You’ve come to this location because tent caterpillars are eating your trees, correct? No surprise that caterpillars are a major pest for trees, and especially fruit trees, in the United States. A large nest of tent caterpillars can quickly defoliate your trees, but don’t worry, I have a very simple method for killing the caterpillars in your trees that uses only ONE simple ingredient that you probably already have in your home right now.

Healthy trees will simply regrow a new set of leaves when they are damaged.

However, if your trees are younger the stress of losing their leaves can greatly hold back their growth or worse still, kill the tree.

The first year they started to produce well we got a major infestation of tent caterpillars.

We lost our apple harvest that year and I knew I never wanted to let it happen again.

To control a pest in your garden you need to understand its life-cycle.

Tent caterpillars can be found in all three of the following kinds, depending on your geographic location. Despite the fact that they seem different from one another, they both cause the same sort of damage to your trees. Contrary to the fall webworm, which may be spotted in trees throughout the late summer and early fall, these are not the same thing.

Eastern Tent Caterpillars

In color, the Eastern Tent Caterpillars are mostly black, with a white stripe running down the middle of their back and a row of bright blue dots on either side of their body. Cherry, apple, and crabapple trees are among their favorite food sources, although they will also consume other types of trees such as shade trees.

Western Tent Caterpillars

The Western Tent Caterpillar is a yellowish-brown caterpillar with a series of blue and orange dots running down its back. They eat fruit from trees such as cherry, apple, plum, willow, birch, poplar, and oak.

Forest Tent Caterpillars

The Forest Tent Caterpillar has a similar appearance to the Eastern Tent Caterpillar in terms of coloration. They are black with white keyhole-shaped markings running down the rear of their bodies. Unlike other tent caterpillars, which build nests in the forks of trees, these caterpillars form a silk mat along the surface of the branches they feed on. Tent caterpillars are one of the most gregarious forms of caterpillars, and they are members of the moth family Lasiocampidae. The eastern tent caterpillar is the most common variation seen in our region, and it is the most common variety in the world.

  1. These eggs develop swiftly, and by three weeks, the caterpillars will have fully developed into butterflies.
  2. Their hatching is timed to coincide with the regrowth of the trees’ leaves.
  3. These are initially extremely little, but as the caterpillars develop in size, they become bigger.
  4. Look very closely at the forks of the tree branches, since this is where they prefer to make their nests.
  5. Typically, this occurs soon before sunrise, throughout the middle of the day, and shortly after sunset.
  6. They then return to their nest once they have done feasting.
  7. In the final stage of the caterpillar’s existence, they separate from one another in order to select a suitable location for forming their individual cocoon.
  8. They are nocturnal, and you have most certainly seen these medium-sized brown moths fluttering around in the dark throughout the night.

They reproduce quickly after hatching, and the females die within a few days of depositing her clutch of eggs. Because you now understand the tent caterpillar’s life cycle, it will be much easier to maintain control.

How To Kill Tent Caterpillars In Your Trees

Tent caterpillar nests are frequently destroyed by burning them with a tiny propane torch, which is highly effective. This is the method I learnt as a child, and I’ve witnessed many others use it to eliminate caterpillar nests. However, there are several drawbacks to this approach.

  1. Caution should be exercised while burning caterpillar nests since it may cause harm to your tree and leave huge, unsightly black patches behind. This is something I’ve done in the past, and it is quite unsightly! It is possible to get around this by cutting the branch after it has been burnt. However, this causes further harm to the tree, and what if your nest is located at a high point in the tree or on a huge branch? You really don’t want to inflict any serious damage to your trees, do you? Indeed, isn’t that what you’re attempting to protect them from in the first place
  2. When the weather is windy, it might also be difficult to burn the nest with a torch since little torches are readily blown out of their holders. If the nest is located at a high point in your tree, going up to it or using a ladder is not the safest option when using a torch

So the really easy way that we came up with for killing tent caterpillars is simplyvegetable oil!

It’s really that straightforward! The understanding of the caterpillar’s life cycle is essential to make this work. You must wait until all of the caterpillars are in the nest at the same time before spraying the nest well with vegetable oil. Because insects breathe via their skin, this method is effective. When they are covered with oil, they are unable to breathe and die within minutes. However, because I’m a frugal person, I keep the wasted oil from our deep fryer, which I then use in this recipe.

I really like the heavy-duty spray bottles that I’ve been using.

I frequently use them not just to make an oil spray for caterpillars, but also to apply combinations of tea tree oil or liquid fertilizers as a foliar spray on the leaves of plants.

The Benefits Of Using Vegetable Oil

  1. It kills the caterpillars swiftly and does not leave any unsightly black patches on the leaves of your plants. If left to its own devices, the nest will disintegrate and collapse in a short period of time. It is also lot simpler to spray the oil on the nest that is higher up in your tree than it is to attempt to burn them with a torch.

Would you like to see just how well this works?

Watch my video to see how simple it is to use this approach of controlling caterpillars in my fruit trees in your own yard. Isn’t it great when you can find simple and safe techniques to keep pests under control in your garden?

Other Ways To Control Tent Caterpillars

While spraying the nests with vegetable oil is my preferred method of controlling these pests, it is no longer effective once they have outgrown the communal nest. However, there are still simple ways to get rid of tent caterpillars on your trees and in your yard. Read on for more information.

How To Get Rid Of Tent Caterpillars With Dish Soap

Another quick and simple method for getting rid of caterpillars is to spray them with dish detergent. The key to making a dish soap spray effective is to avoid allowing the soap to froth excessively. Fill the spray container almost to the brim with water, then add 1-2 teaspoons of dish soap per gallon of water and shake well. After that, finish topping off the water supply. Give the sprayer a slight shake to ensure that all of the soap is included. This helps to keep the soap suspended in the water rather than having it float to the surface as bubbles.

Use BTK Spray

The best alternative if your trees are being devoured by tent caterpillars but you can’t discover a nest to remove is to use an organic BTK (Bacillus thuringiensis) spray, which is safe and effective.

This naturally occurring bacterium is only harmful to caterpillars, and it is completely safe to use around birds and bees. Simply spray BTK on the leaves of your trees, and the caterpillars will be killed as a result of eating the poison.

Tent Caterpillars – How do I get rid of tent caterpillars?

Wizzie Brown contributed to this article. Tent caterpillars attack a variety of broadleaf trees and shrubs, causing unattractive webs, or tents, to appear on the leaves. When their populations reach a critical mass, the caterpillars can defoliate trees, causing them to develop more slowly. They prey on ornamental and fruit trees, among other things. Early and correct identification of tent caterpillars, knowing their life cycle, and the use of suitable cultural or chemical management strategies are all essential for their eradication from the environment.

The eastern tent caterpillar, Malacosoma americanum, is the most troublesome of the four.

Life Cycle

Female moths lay their egg masses on tree trunks or tiny twigs throughout the late spring to early summer period (Fig. 1). The females of all Texas species, with the exception of the Sonoran tent caterpillar, utilize spumaline, a sticky, foamy substance, to “glue” the eggs to the bark or twigs of trees and shrubs. The spumaline also functions as a protective shell surrounding the egg mass, providing a firm, durable surface. During the majority of the summer, fall, and winter, egg masses linger on the branches of the trees.

  1. Eastern and western tent caterpillars begin feeding on these fresh leaves within a few days of their appearance.
  2. In most cases, the web is situated in the crotch of tiny limbs (Fig.
  3. Because the larvae wander away from their tents to feed on leaves, harm can occur even if the web is located a long distance away from the tents.
  4. These enormous, noticeable webs are created by the eastern and western tent caterpillars.
  5. The larvae molt, or lose their skin, multiple times throughout their development.
  6. The color pattern can also alter from instar to instar depending on the species.
  7. 3).
  8. Between feedings, dozens of caterpillars may assemble on these mats to wait for their next meal.
  9. Protected areas like as the web, under the bark, among dead plant material on the ground, within a curled leaf, or under the eaves of homes are all common locations for spiders to hide.
  10. Generally speaking, cocoons are loosely made of silk with a white or yellowish crystalline component dispersed throughout the whole thing.
  11. Tent caterpillars in their adult form are brown and yellowish moths with two diagonal patterns on the front wings of their bodies (Fig.

4). Their wingspans are around 1 inch in length. They are drawn to lights, like do other moths. A single generation of tent caterpillars occurs once a year in all species. Adults only survive for a few days, during which time they mate, lay eggs, and do not consume any food.

Biology

Tent caterpillars in its infancy are brightly colored and grow to be approximately 134 inches long when fully grown. The only lengthy hairs on their body are found around the sides and on the back. Individual species may be distinguished by the colors and patterns on their larvae. If you come across tents with larvae that do not fit the descriptions in Table 1, it is most likely that they are autumn webworm tents. Fall webworms may construct tents throughout the late summer and fall and can have numerous generations per year, depending on the species.

Management

The degree of defoliation, unattractive webs, and nuisance caused by the caterpillars should be taken into consideration when developing a management strategy. It is possible that you may need to utilize a combination of cultural and chemical procedures to achieve the optimum results. Control over one’s culture. During winter pruning, look for egg masses, which show as swellings on tiny, naked branches and are a sign of infestation. When trees are pruned, the tent caterpillar eggs are frequently removed before they develop.

  1. When you discover spider webs on twigs in the spring, prune them as soon as you notice them.
  2. It is not suggested to burn the web or caterpillars since it is quite dangerous.
  3. Remove the dead caterpillars from the ground and dispose of them.
  4. Beneficial insects can help to lower the number of tent caterpillars.
  5. Trichogramma species prey on the eggs of tent caterpillars.
  6. Control through chemical means.
  7. The use of insecticide is pointless if the tent caterpillars have been allowed to feed and develop to completion.

Tents are weather-resistant and will remain in the tree for an extended period of time until they are removed.

Early morning or late evening applications are recommended in order to concentrate the spray on the tents when the caterpillars cluster.

The species that may be sprayed with these oils will be listed on the label of the product.

Some organically generated goods contain active substances such as Bacillus thuringiensis (Bt)varietykurstaki, spinosad, or insecticidal soap, which are all derived from bacteria.

In order for the Bt kurstaki and spinosad to be taken up and consumed by the caterpillars, spray the plant well before applying the substance to the leaves.

Contact-kill insecticides such as insecticidal soap must be applied directly to the caterpillars in order for them to be killed.

Some of these formulations operate when they come into direct contact with the pest, while others may have an oil-based component that is comparable to horticultural (petroleum-based) oils in their composition.

There are several long-lasting, synthetic pesticide solutions available that give quicker and longer-lasting control than most plant-derived insecticides while also working on all phases of the caterpillar’s life cycle.

Bifenthrin, cyfluthrin, esfenvalerate, fluvalinate, permethrin, lambda-cyhalothrin, indoxacarb, acephate, and carbaryl are all active chemicals to search for in a pesticide formulation.

Pesticide users are accountable for the impact pesticides have on their own plants or home goods, as well as any difficulties that may arise as a result of pesticide drift from their own properties to the properties or plants of their neighbors.

Also prone to change are the regulations governing the use of insecticides and pesticides. Always read and carefully follow the instructions on the product label for the most dependable instructions.

How to Get Rid of Tent Caterpillars

Tent caterpillars are the larvae of various moth and butterfly species (mentioned below), which are referred to as a group by their common name. These caterpillars, which are found throughout most of the United States and Canada, reproduce quickly and have the ability to defoliate a significant number of deciduous trees and shrubs in a short period of time. These pests are frequently seen on wayside trees and in abandoned orchards. Aside from defoliation, the larvae build big unattractive webs, or tents, in the crotches of tree limbs, which are difficult to remove.

Despite the fact that tent damage is ugly, infestations of insects seldom endanger the life of trees.

Identification

The Eastern Tent Caterpillar (Malacosoma americanum) is a species of caterpillar that may be found east of the Rocky Mountains and north into southern Canada. In their full developed state, caterpillars are sparsely hairy and black in appearance, with a row of pale blue markings on either side of their bodies. They may be distinguished by a white stripe running down the middle of their backs, which helps to identify them. Adults are reddish brown moths that are 1-1/2 inches in length and have two white stripes running diagonally across each forewing.

  • The Western Tent Caterpillar (Malacosoma californicum) is a pest that may be found in the northern and western regions of the United States as well as in adjacent Canadian territory.
  • Approximately 1-1/2 inches in length, adult moths are orange-brown in color with two faint yellow lines on the underside of the wings.
  • Malocsoma disstria is a forest tent caterpillar that may be found across the United States and Canada anywhere hardwoods can be found in the forest.
  • americanum are similar in appearance to the adult, but instead of a solid line running down their back, they have a series of keyhole-shaped white dots.
  • Wild cherry, aspen, maple, oak, and hawthorn are among the plants that serve as hosts.
  • Webworms are known to feed on over 85 different types of trees and are found across North America and Mexico.
  • One-inch-long caterpillars are coated with long hairs and range in color from yellow to green, with a black stripe along the back and a yellow stripe on each side of the body.

The color of their heads is either red or black. Adult moths (1 inch in length) are pure white in color with black markings on the wings, which are characteristic of the species.

Life Cycle

The egg stage is where the majority of tent caterpillar species overwinter. Egg masses ranging in color from dark brown to gray and holding 150 to 400 eggs are adhered to the short twigs of trees and bushes. Hatching takes occur around the time when leaf buds begin to open, which is normally in the early spring months. They are social creatures who quickly build silken tents, which they use as a haven during the early morning and evening hours, as well as during rainy spells, to protect themselves from the elements.

The larvae reach full maturity around six weeks after hatching and five instars following that time period (up to 2 inches long, sparsely hairy).

Adult moths emerge around two weeks later and deposit the overwintering eggs within a short period of time.

Note: When larvae begin to travel to sheltered regions in order to pupate, they can become a nuisance.

How to Control

  1. Prevent the larvae from starting to eat by scraping off and discarding overwintering egg masses and tearing the protective tents out by hand before they start to feed. With this method, you may restrict caterpillar mobility and deny them access to eating locations. Sticky Tree Bands or Tree Tanglefoot Pest Barrier are two options for preventing pest infestations. The naturally occurring soil-dwelling bacteriumBacillus thuringiensis, often known as Bt-kurstaki, is highly powerful against all species of inch worms. At the first indication of damage, use a spray that is simple to apply to knock out the worms and safeguard the foliage. It is safe to use BTKsprays near dogs and children since they do not damage honey bees or birds
  2. Spinosad, a biological substance developed from fermentation, is also extremely useful in a variety of applications. In fact, it’s the active ingredient in Monterey Garden Insect Spray, a product that has been classified as organic by the United States Department of Agriculture’s National Organic Program and listed for organic use by the Organic Materials Review Institute
  3. AzaMaxcontains azadirachtin, which is the key insecticidal ingredient found in neem oil. This very powerful spray interferes with the growth and development of nuisance insects while also acting as a repellant and anti-feedant. In addition to being non-toxic to honey bees and many other helpful insects, it should only be used as a last resort for dealing with bug infestations. Natural pesticides, which are derived from plants that contain insecticidal qualities, have less adverse side effects than synthetic chemicals and degrade more quickly in the environment.

Note: Although more than 80 species of predators and parasites have been identified in the United States, none of them are now available for purchase on the market. During the majority of the year, these insects serve a crucial role in keeping pest populations under control. As a result, extreme caution must be exercised while spraying pesticides in order to avoid causing harm to these important species.

Home Remedy for Tree Caterpillars

The majority of the time, caterpillars of butterflies and moths do not pose a significant threat to tree health in North America. There are many species that eat the leaves of trees, inflicting superficial harm and, when in great numbers, limiting the amount of leaves that are produced by the trees, which provides them with food. Other caterpillars pose a threat to the health of smaller plants. Unfortunately, the use of pesticides and insecticides can cause considerable harm to other plants, animals, insects, and microorganisms in the area where they are sprayed, as well as to the people who use them.

What Are Caterpillars, and What Kinds Will Hurt Trees?

The phrase “caterpillar” refers to the larval stage of several insects, including moths and butterflies. There are many thousands of different variations, and as a result, they can range from smooth to spiky to hairy in appearance. In general, though, they have somewhat long bodies, many feet, and a mouth that is adapted to devour plant stuff, among other characteristics. Caterpillar webs can be found on shrubs and trees, and many people will notice them. Tent caterpillars, sometimes known as tent worms, leave behind silken bags that are easy to identify.

A variety of trees are targeted by the eastern tent caterpillar (hairy and 2-inches long with rows of blue spots down their backs), while the western tent caterpillar (similarly long with a black body and white stripes down the back) targets the same trees as their eastern counterparts as well as aspen, willow, poplar, birch and a variety of other trees in the western United States.

Soap to Remove Tree Caterpillars

Although pesticides have proved to be quite effective in the removal of caterpillars, they can also kill beneficial insects in the process. The usage of common household soap, on the other hand, can be used to make DIY “insecticides.” The procedures for accomplishing this are pretty simple. The first method involves dissolving soap flakes in a liter of water by stirring constantly until they are completely dissolved. Use finely minced onions, garlic and fiery chilies to make an all-around pesticide by covering the ingredients with warm water and soap.

Remove the plant stuff by straining it out and diluting it with additional water.

It is effective against other insects as well.

Other Methods to Remove Tree Caterpillars

Making handmade barrier bands, which are bands coated in a sticky material that catch caterpillars that have wrapped themselves around the trunk of a tree, is another option. They can be created in a variety of methods, but they must fit specific requirements. A minimum of 2 inches in width, manufactured of a sturdy and rain-resistant material, and the sticky material must remain sticky for extended periods of time are all requirements. Tanglefoot, horticultural glue, or petroleum jelly (which isn’t sticky but can still capture caterpillars) are all options.

Remember to avoid placing any chemicals directly on the bark of a tree because this might do it harm.

However, while some “pests” that are good to the environment are attracted to backyard gardens, they are also attracted to a number of creepy crawlers that are destructive to the plants, such as caterpillars. It is the voracious appetites of these microscopic rodents that have left disgruntled homeowners on the lookout for their destruction.

Method 1: Hand-Pick Your Least Favorites

Hand removal of caterpillars is the most efficient method of dealing with the problem—specifically, glovedhand removal. Toss a couple of teaspoons of mild dish soap into a bucket half-full of hot water, then put on a pair of rubber or canvas gardening gloves and walk out to your garden to perform a new type of picking. Instead of picking caterpillars off the leaves, you’ll want to lift them off the undersides of the leaves, where caterpillars are renowned for hiding, and put them into the bucket to drown them in the bucket of water.

The protective hand gear will prevent you from being stung by the spines on some caterpillar kinds, like as the saddleback, when you are handling them in your hands. While this strategy is the most proactive, it may take a number of repetitions in order to completely eliminate the population.

Method 2: Empty the Nest

The destruction of the caterpillars’ nest is a more aggressive approach to the problem, and it is literally more hostile. These silk-spun dwellings may often be found dangling from tree limbs in the wild. Simply insert your instrument of choice (either a long sharpened stick or a broom handle will work well) into the nest itself, then spin and scrape your way through the nest’s inside to remove all of the creatures that have taken up residence within. Remove the nest and its contents after that, then submerge them in a basin of warm, soapy water to kill any caterpillars that are still alive.

However, if any leftover caterpillars manage to rebuild their house, this procedure may need a few further rounds before it becomes successful.

Method 3: Poison the Hungry Caterpillars’ Food

Homeowners who are not interested in finding and handling these pests might choose to give Bacillus thuringiensis, which is a hands-off—and hands-down most effective—extermination option (Bt). Caterpillars are killed in a couple of days by this naturally occurring soil bacterium, which attacks and destroys the lining of their stomachs. Put the powder or mist straight onto your garden plants, and then wait for the caterpillars to get interested. Don’t be concerned about unwanted side effects when you use this product: Bt is absolutely non-toxic to plants, pollinators, pets, and humans in general.

If your infestation persists after a week or two, you will need to reapply because your first treatment will have degraded due to exposure to direct sunshine and moisture.

Method 4: Homemade Caterpillar Deterrent

Instead of spending money on caterpillar control, you may make a homemade solution that will work just as well as the professional kind. When spraying plants with a molasses solution (1 tablespoon molasses, 1 teaspoon dish soap, and 1 liter of warm water) or a garlic solution (three smashed cloves of garlic, 1 tablespoon vegetable oil, 1 teaspoon dish soap, and 1 liter of water), insects are discouraged from eating the plants.

How to Get Rid of Eastern Tent Caterpillars

It’s possible that you’re dealing with a widespread insect found across North America: the tent caterpillar, if you detect web-like formations between branches of your trees, including your decorative and fruit trees. Rather from being pests, these pests are really the larvae of several different varieties of moths that establish their homes in your trees and eat on the leaves of plants. They are appropriately called for the prominent silk tents that they construct in the branches of their host trees throughout the course of their life cycle.

Tent caterpillars may be extremely destructive to plants, so understanding how to get rid of them and using safe management measures can help you preserve your plants from potentially devastating infestations.

The type of tent caterpillar you’re dealing with, as well as the most effective management strategies, can be determined by your geographic region.

Eastern Tent Caterpillars

Eastern tent caterpillars may be found in abundance throughout the eastern United States and the Rocky Mountains. Infestations of this species can inflict considerable harm to the look of ornamental trees, and their populations fluctuate from year to year. Soon after hatching, the caterpillars crawl up into the bends of trees where they construct webs to keep themselves warm. These parasites can be found in a range of common host trees. Eastern tent caterpillars have a hairy black body with yellow stripes and oval-shaped blue spots down the sides, and they are a kind of moth.

Gypsy moths, on the other hand, do not have this stripe.

Western Tent Caterpillars

West-coast tent caterpillars are more frequent in the Northwest, although western tent caterpillars may also be found on particular host trees in the southern Rocky Mountains, where they are known as forest tent caterpillars. The two are roughly the same size, but they differ in a number of significant ways. The tent caterpillars of the western hemisphere are orange with black patterns that run down their backs. As soon as their eggs hatch in the spring, their “tents” begin to emerge. Trees are beginning to blossom at this time, and these pests begin feasting on new growth as soon as they emerge from their eggs.

Forest Tent Caterpillars

West-coast tent caterpillars are more frequent in the Northwest, although western tent caterpillars may also be found on particular host trees in the southern Rocky Mountains, where they are known as mountain tent caterpillars. Despite the fact that they are about the same size, the two are distinct in other ways. These caterpillars are orange with black patterns running down their backs, which distinguish them from other tent caterpillars. It is during the spring season that they begin to emerge from their “tents.” Trees are beginning to blossom at this time of year, and these pests begin feasting on new growth as soon as they hatch from their egg cases.

Other Insects That Are Mistaken for Tent Caterpillars

There are several different sorts of moths and insects that are often mistaken for tent caterpillars, including lacewings and aphids. They have a variety of consequences for your property.

Gypsy Moths

Gypsy moth caterpillars are distinct from tent caterpillars, which implies that gypsy moth caterpillar control methods will differ slightly from tent caterpillar control methods. Gypsy moths don’t come in the spring, but rather later in the year, when the weather warms up. An entirely new generation arises each year, and they harm a wide variety of ornamental shrubs, conifers, and trees. They can also be seen on fruit trees and shrubs.

Fall Webworms

If you hear someone mention tent worms, it’s possible that they’re referring about autumn webworms instead. Although they are not tent caterpillars, the terms “tent caterpillar” and “tent caterpillar” are sometimes used interchangeably. Fall webworms are distinguished from eastern tent caterpillars by their appearance and behavior. They are creamy-white, hairy, and speckled with black spots, but eastern tent caterpillars are not.

Their webs are spun over the tops of branches and leaves, and they also eat within their webs, as opposed to tent caterpillars, which only utilize their tents for protection. Fall webworms are most active during the fall season, as the name indicates.

Tent Caterpillar Lifecycle and Control

Knowing the pest’s lifecycle is essential when dealing with tent caterpillars or removing a caterpillar infestation from your property. During the early spring, eastern tent caterpillars make their initial appearance and finish their lifecycle by the end of the summer. This implies that host trees have more time to produce new foliage and are less likely to perish as a result of an infestation. They can, however, do damage to the beauty and health of a tree. During the months of January through March, eastern tent caterpillars deposit their eggs in host trees.

Pruning and the introduction of natural predators are two more techniques of removing tent caterpillars from a structure. The natural enemies of caterpillars include birds and wasps, among others. Predators pluck these bugs out of trees and consume them because they are poisonous. As an alternative, if the caterpillars’ tents are within reach, you might consider cutting off the afflicted branches and burning them to get rid of tent caterpillars completely.

tent caterpillar control and treatments for the yard home and garden

Tent caterpillars are a very busy pest that may be found throughout the year. They have voracious appetites and will consume nearly any plant they come upon. Their nests are unattractive, their feeding habits are detrimental to plants, and they quickly move inside practically any building, creating a shambles in the process. Tent caterpillars are covered in full in this article, which will also explain how to control local infestations and nests on your property, as well as what products to use.

  1. These animals are normally dark in appearance — primarily black – with a few lengthy, brightly colored stripes running down their backs.
  2. It is possible that these lines be brown or yellow in color.
  3. Even though they are scarcely detectable at this time, they will become more active when the surrounding plant life begins to produce their spring foliage in the coming months.
  4. In the event that the host tree or shrub on which they originated does not supply sufficient food, the ants will travel to other adjacent native plants for sustenance.
  5. Every evening after dark, the spiders will return to their host tree and begin spinning a “tent” that will continually expand to meet their ever-increasing size.
  6. These tents, which are generally ugly, are white and silky in appearance and arise where the host tree’s limbs grow in two different directions at the same time.
  7. These colonies will begin with several hundred caterpillars, and their “tents” can range in size from as tiny as a soccer ball to as huge as a compact automobile!

All of the tents will have been deserted, and caterpillars will be observed traveling in all directions, with no apparent purpose in mind.

In the course of their journey, they would frequently crawl on top of houses.

Once they have selected a comfortable area where they feel safe and sheltered, they will spin a cocoon and go through the process of transformation.

Females (adult moths) will search for a suitable host plant on which to lay eggs, and after they have located one, they will deposit 200-300 eggs on a branch that is kept together by a sticky material that is produced as part of the egg laying process.

When tent caterpillars feed, they may do a great deal of harm.

Because they will be unable to perform normal photosynthesis without their leaves, they will have to expend a significant amount of time and energy growing new leaves to replace those that have been lost, and as a result, they will be significantly more vulnerable to other problems such as disease and parasites.

Furthermore, caterpillar droppings will be found below host plants and will create a sloppy mess on automobiles, homes, lawn chairs, and other items of furniture.

They may be found beneath any host plant and can become quite a nuisance if the local populace is in high numbers and consuming the droppings.

Their excrement is acidic, and it will “eat” through almost any type of car finish, causing it to rot.

In proportion to the size of each individual caterpillar, the colony will expand the size of their “tent.” Despite the fact that caterpillars begin each season small and barely noticeable, they will eventually grow to be more than 2 inches in length, necessitating the expansion of the nest’s “tent” to accommodate each individual’s larger size.

Don’t be surprised if you come across nests the size of a basketball or even bigger.

From year to year, trees that have been successful in attracting nesting birds will attract more birds because previous generations will instinctively recognize a good host plant.

And if the damage, droppings, or unsightliness of their nests isn’t enough to make these insects a bona fide nuisance, their annual migration surely will.

Once larvae have had enough to eat, they will start to leave the main nest in search of a good location where they can undergo metamorphosis.

They like to choose secure and discreet locations for this change and seem to like man made structures just as much as any tree.

The migrating larva will be out in great numbers during this time traveling in all directions from the main nest and if they encounter a home or other structure, chances are they will try to make it their home for the next month.

In fact many homes will actually get invaded each yearif they are located in the migration path of tent caterpillars.

Fortunately, there are some very effective treatment options for controlling tent caterpillars.

This concentrate is basically a concentrated bacteria.

Thuricide can be sprayed on any plant, vegetable or fruit without posing a hazard and is a good preventive material to use – especially if you are treating before they arrive.

Retreat every 2 weeks.

Another approach is to apply a band ofINSECT GLUEaround the trunk of any targeted tree.

Make the band at least 1 inch wide; a tub of Insect glue is enough to treat 3-5 large trees.

This is an excellent protective treatment that will stop all insects from accessing beneficial plants.

There are a few organic products approved and certified for caterpillars but we have foundBT GARDEN DUSTandMULTI PURPOSE INSECT KILLERto perform the best.

Feeding caterpillars will die within 7-10 days of eating plants and foliage with BT dust.

If you have tall trees, dusting will be ruled out as an option.

This fast acting concentrate is approved for use on organic gardens (fruits and vegetables) and will last up to 7 days so expect to treat weekly when caterpillars are active.

The strongest spray available for killing tent caterpillars immediately isBIFEN XTS.

It has a very low odor and will both kill quickly and last a long time.

Mix 1 oz per 5 gallons of water and use this to treat up to 5,000 sq/ft of turf and plant foliage surface area.

This additive will allow the concentrate to better coat the target plant and the caterpillars when spraying them directly.

Spreader Sticker will help get coverage in these areas by dispersing the spray once it lands on targeted treatment sites.

Add 1 oz per 5 gallons of mixed solution with the Bifen.

The Bifen XTS with Spreader Sticker will typically work if you can strike the nest with enough strength to penetrate.

Wait until the evening before treating active tents.

Next, prepare the spray and ensure that the sprayer you are using will be able to reach a high enough altitude to adequately wet the nest.

Huge enough for the treatment to penetrate, but not so large that all caterpillars fall out, is the ideal size for holes in the ground.

Soak it to the point of runoff, ensuring that the ones already there will be killed and that a long-lasting residue will be present to capture those that may have escaped.

Although this substance is often used to control bees and wasps, the particular mixture has been discovered to be effective against caterpillars as well.

A single can of insecticide should be sufficient to treat between one and three average-sized nests.

The migrating adult tent caterpillars are a serious threat to the safety of your home.

First, CYPERMETHRIN should be sprayed on the whole outside of the house.

As a precaution, spray the eaves and undersoffits of any buildings that have caterpillars up in them or under them.

1 oz per gallon of water, plus 1 oz of the Spreader Sticker (see above) to your tank mix will yield a good result.

Cypermethrin can be applied to affected areas if the pests have already entered the house.

Because it comes with a convenient tube injector, it is more suited for getting into cracks and crevices.

A good treatment should be administered as soon as possible since tent caterpillars will stay active for a few days inside the residence.

In order to spray for tent caterpillars, anyPUMP SPRAYERwill suffice.

If you need to reach heights of 20 feet or more, a TROMBONE SPRAYER is the best option.

SPRAYER AT THE END OF THE HOSE is another possibility.

Tent caterpillars are generally regarded to be non-venomous pests.

Using any of the concentrations indicated above, you can keep them under control in the backyard.

However, once inside the house, apply Cypermethrin and FS MP Aerosol to exterminate the intruders.
