How To Keep Tent Worms Away

Eliminating Tent Worms – Tent Caterpillar Home Remedy Solutions

Nikki Tilley, author of The Bulb-o-licious, contributed to this article. Malacosoma americanum (tent worms) are a common sight in the garden, although they pose little damage to the health of the gardener or his or her family. Getting rid of tent caterpillars, on the other hand, is occasionally essential. We can look into ways to avoid tent worms and, if required, how to eliminate tent worms from your home.

About Tent Worms

Tent caterpillars are commonly mistaken with autumn webworms, although they are very distinct creatures. Tent worms are most active in the early spring, whereas webworms are most active in the late summer and early fall. Tent worms build their tent-like nests in the forks of branches, whilst webworms build their web-like nests at the extremities of branch forks. Fall webworms construct nests that include foliage or leaves as well as their own bodies. Tent caterpillars, on the other hand, do not.

They will, however, build their nests in ash, willow, and maple trees as well as other species.

Large colonies, on the other hand, can cause severe defoliation of trees because they feed on the leaves.

Tent caterpillars may also graze on neighboring plants, according to the USDA.

Tent Caterpillar RemovalTent Caterpillar Home Remedy

It is frequently possible to pluck out the tent caterpillar nests or egg cases by hand when tent caterpillar removal is required. When the leaves fall off the trees in the fall, egg cases are plainly seen. Larger nests may be removed by looping them around a stick, or they can be pruned out and disposed of in the trash. The optimum time to remove tent caterpillars from their nests is in the early morning or late evening, when they are most likely to still be in the nest. The introduction of natural enemies, such as different species of parasitic wasps, can also aid in the reduction of tent worm populations.

How to Kill Tent Worms

When it comes to getting rid of tent caterpillars, sometimes the only option is to kill them. While tiny infestations may be controlled by dumping the nests into soapy water, contact pesticides are the most effective method for controlling bigger populations. Bacillus thuringiensis (Bt) is the most effective of the bacteria types. Because this is a selective pesticide, it only kills tent caterpillars while staying safe for use around other animals.

Directly spray the foliage and tent worm nests with the product. Following these simple techniques will make getting rid of tent caterpillars a piece of cake. The beauty of your trees will be restored in a short period of time. The information in this page was last updated on

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.


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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Wild cherry, aspen, maple, oak, and hawthorn are among the plants that serve as hosts.
  6. Webworms are known to feed on over 85 different types of trees and are found across North America and Mexico.
  7. 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.

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 corrosive, and it will “eat” through almost any type of automotive finish, causing it to deteriorate.

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 little and scarcely apparent, they will eventually grow to reach more than 2 inches in length, necessitating the expansion of the nest’s “tent” to suit each individual’s increased size.

  • Don’t be shocked if you come across nests the size of a basketball or even bigger.
  • From year to year, trees that have been effective in attracting nesting birds will attract additional birds since past generations will automatically recognize a suitable host plant.
  • In addition, if the damage, droppings, and unsightliness of their nests aren’t enough to establish them as a legitimate annoyance, their yearly migration will undoubtedly do the trick.
  • They will begin to leave the main nest once the larvae have consumed sufficient food in order to find an appropriate site where they may undergo transformation.
  • They like to move sites in a safe and discrete manner, and they appear to enjoy man-made structures just as much as they do natural trees while doing so.
  • During this period, the migrating larva will be out in large numbers, moving in all ways from the main nest, and if they come across a house or other structure, they will almost certainly attempt to make it their home for the next month.
  • Indeed, if your property is near the tent caterpillars’ migration route, you may find yourself the victim of an invasion each and every year.

Tent caterpillars are a difficult pest to remove, but there are several extremely efficient treatments for them available.

This concentration is essentially a concentrated bacterium in a concentrated form.

It is safe to spray thuricidal solutions on any plant, vegetable, or fruit without creating a concern, and it is an excellent preventative item to use – particularly if you are treating before the pests come.

Every two weeks, go on a retreat.

Another strategy is to place a band of INSECT GLUE around the trunk of any tree that has been identified.

Make the band at least 1 inch wide; a container of Insect adhesive will treat 3-5 big trees if the band is 1 inch wide.

This is a fantastic preventative treatment that will prevent all insects from gaining access to valuable plants in the future.

Organic products recognized and certified for caterpillar control are few, however we have discovered that BT GARDEN DUST andMULTI PURPOSE INSECT KILLER provide the most effective results.

Caterpillars that are fed with BT dust will die within 7-10 days of consuming plants and leaves treated with the dust.

Because of the height of your trees, dusting will not be an option for you.

While used on organic gardens (fruits and vegetables), this fast-acting concentrate is permitted for usage.

Use no more than 800 sq/ft of foliage to apply the mixture, which should contain 5 oz per gallon of water.

The use of this concentrate on food crops is not recommended; nonetheless, it is wonderful for any tree, shrub, or even for the home’s landscape.

Bifen treatments can last for up to a month and can effectively eliminate virtually every bug that comes into contact with them on treated surfaces.

Because caterpillars have a lot of hair, you need use SPREADER STICKER in your tank mix.

When spraying plants, it is often difficult to get enough coverage due to the fact that leaves have undersides that are resistant to direct spray.

Furthermore, it will increase the immediate effect that Bifen has on the caterpillars that have been targeted.

If you have a large number of nests that you wish to cure immediately, you have two alternatives.

This might be difficult due to the fact that most nests will be located high up the tree and the webbing can be fairly thick.

This will ensure that all caterpillars have returned to the nest and are laying eggs inside of it.

Make three or four holes in their tent with a stick or pole.

Once the access holes have been created, spray the nest with the solution that you have prepared.

HORNET KILLER is another product that may be used as a direct therapy.

Prior to spraying the tents, you will still need to poke 3-4 holes in each of them, but once the access points have been created, soak the nest down for an efficient kill.

Remember, this is only effective for treating nests directly; it is not recommended for spraying over leaves, since this will cause harm to the tree, shrub, or other plant being treated.

Fortunately, there are two items that will both prevent them from entering and kill them if they do attempt to do so.

This concentrate, when mixed with water, may be put to the foundation and up the side of the house a few feet to create a barrier that caterpillars will be unable to crawl through.

Cypermethrin is extremely irritating to caterpillars and will kill those that are present while also leaving a strong residue to deter future infestations.

When caterpillars are active, apply 1 gallon per 500 sq/ft of surface area and retreat once every 2 weeks while they are active.

However, FS MP AEROSOL should be used in areas where a liquid cannot be used.

It, too, may be used along baseboards, around window frames, and even higher up on the ceiling by way of crown molding.

If you don’t act quickly, you may expect to observe a large number of adult moths hatching out of pupa cocoons in the first 1-2 months after the first invasion.

Our regular sprayer has a maximum reach of approximately 15 feet and is adequate for small applications.

It is capable of reaching distances of up to 30 feet and is fully portable due to the fact that it operates by pumping out a mixed solution from a 5 gallon bucket.

These will spray as far as your garden hose is capable of reaching.

However, once they begin their spring feeding, their chewing and devouring may cause significant damage and stress to a wide variety of trees and plants.

With any hope, this will prevent them from entering the structure.

Treat early in the season to keep tent caterpillar numbers under control; kill as many as you can once the season is in full bloom otherwise you will have that many more tent caterpillars to deal with the following year if you do not treat early in the season.

How to Get Rid of Spring Webworms or Eastern Tent Caterpillars

Tree leaves aren’t the only things that burst forth from their shells in the springtime. Pesky insects come to life in the spring after spending the winter hibernating in a safe place. Certainly, tent caterpillars, whose thick, spun webs block out the light from a tree’s blossom, are an example of this phenomenon. Tent caterpillars, on the other hand, are rather easy to get rid of, whether you use a pesticide or a simple home treatment.

Your Guide to Getting Rid of Spring Webworms in Trees

These furry little insects, sometimes known as tent worms or Eastern tent caterpillars, are known for eating tree leaves and weaving huge, silky webs around the limbs of trees. The best time to see them is in the spring, when they may be seen on black cherry, apple, or crabapple trees. They’ll sometimes go for other types of fruit trees as well.

Are tent caterpillars harmful to trees?

When it comes to healthy, mature trees, tent caterpillars are typically not a big hazard. They do take away some of the leaves from the trees and spin some unsightly webs, but that is the extent of their harm to the trees. Only two exceptions exist: black cherry trees, which are particularly prone to tent caterpillars, and young trees, which are extremely vulnerable to tent caterpillars. If you notice caterpillars or their spider-like webs on trees, treat them as soon as possible.

How to Get Rid of Tree Worms

It is really simple to get rid of tent caterpillars. Follow the instructions outlined below to bid these pesky creatures goodnight!

  1. Remove the spider webs by hand, and then use dish soap to destroy the tent worms. If you only have a few of tents, you may simply remove the webs off of the branches with your hands. Choose a time of day when the caterpillars are still within their webs, such as early morning or late evening. If you don’t want to get your hands dirty, you can wrap the webs around a broomstick. Once they are done, place them in a bucket filled with water and dish soap. Take things seriously. When dealing with enormous infestations that are impossible to eradicate by hand, a pesticide containing Bacillus thuringiensis, sometimes known as “Bt,” is extremely successful. Carefully read and follow the packaging directions. Alternatively, contact your local arborist and ask them to handle it. In the winter, you should get rid of caterpillar eggs. Look for eggs on tree branches in the winter to see if the caterpillars have laid any. The eggs will look like glossy, reddish-brown bulbs and will be visible through the winter. You can try scraping them off, and if that doesn’t work, you can trim the branches off the tree.

You’ve come to this location because tent caterpillars are devouring your trees, correct? No surprise that caterpillars are a major issue for trees, and especially fruit trees, in the United States. A huge nest of tent caterpillars may quickly defoliate your trees, but don’t worry, I have a really simple method for killing the caterpillars in your trees that takes just ONE simple thing that you probably already have in your house right now.

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

However, if your trees are young, the stress of losing their leaves might cause them to develop more slowly or, in the worst case scenario, cause them to die.

We had a significant infestation of tent caterpillars the first year they started to produce properly, which was really frustrating.

That year, we were unable to harvest our apple crop, and I vowed to myself that this would never happen again. I’ve discovered a natural solution to eliminate the tent caterpillars that are attacking our trees, and I can’t wait to share it with you so that you can defend your trees as well!

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.

  • These eggs develop swiftly, and by three weeks, the caterpillars will have fully developed into butterflies.
  • Their hatching is timed to coincide with the regrowth of the trees’ leaves.
  • These are initially extremely little, but as the caterpillars develop in size, they become bigger.
  • Look very closely at the forks of the tree branches, since this is where they prefer to make their nests.
  • Typically, this occurs soon before sunrise, throughout the middle of the day, and shortly after sunset.
  • They then return to their nest once they have done feasting.
  • 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.
  • 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.

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.

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

Caterpillars that live in forest tents are distinctive in appearance. It is easy to distinguish them by their blue hue with black specks and the white marks in the shape of feet in the center of their backs, which are in the middle of their backs.

Similarly to spider webs, these are silken mats that are placed between tree branches, and they are not regarded to be “tents.” Some examples of host plants are as follows:

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.

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.

  • Adult moths begin producing new batches of eggs in the summer and continue to do so through the fall and into the early winter months.
  • Safer®Brand Caterpillar eggs are killed by BioNEEM®, a neem oil concentration that is used to kill the eggs of a range of insect pests, including caterpillars.

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 Worm Control: How To Get Rid of Tent Caterpillars (Tent Worms)

This page contains a general control guide for the Tent Caterpillar. Tent Caterpillars can be controlled by using the goods and procedures that have been recommended. If you follow this advice and utilize the recommended products, we promise that you will have complete control over Tent Caterpillars. Those of you who have shrubs, fruit-bearing trees, or other ornamentals in your yard or garden may have noticed Tent Caterpillars on your plants (also known as Tent Worms). Tent caterpillars are notorious for their voracious appetites and may do major harm when they invade landscapes in huge numbers, defoliating trees and wreaking havoc on the environment.

They are most commonly seen in the yard, where they graze on fallen leaves and other organic matter.

Crawling on automobiles and causing damage to the paint job with their droppings is another common occurrence for tent caterpillars.

The following do-it-yourself approach might assist you if you have an infestation of these pests on your land or even inside your home.


First and foremost, be certain that you are dealing with Tent Caterpillars or Tent Worms rather than something else. Because of misidentification, you may end up adopting the incorrect treatment approaches, which may waste your time and money if such procedures are unproductive. Tent Caterpillars exhibit the following characteristics, which might assist you in identifying them:

  • Tent Caterpillars are 2 to 2.5 inches in length and are normally black in color with an often ornate brilliant colored pattern of stripes running down their backs
  • They are also known as tent caterpillars. They hatch out of eggs in the spring, generally from a mass of 150 to 400 eggs, and are known for their hairy and brightly colored appearance. Tent Caterpillars are extremely gregarious creatures, and as they hatch from the mass, they form a white silky tent around themselves, which they use to shelter in in the crotch of a host tree. Their name comes from the fact that they live in a tent-like nest. As the caterpillars increase in size, the tent gets larger and more visible on the ground. When the caterpillars reach adulthood, they begin to leave the tent and roam around aimlessly, with no specific destination in mind. When the caterpillar finds a suitable location to pupate, it will construct a cocoon and, after a period of time, will emerge as a moth, where it will seek a partner, lay eggs, and repeat the cycle.

It is important to note which trees and areas of the yard are more heavily infested so that you may target them during the inspections. Where To LookFor InfestationsBecause the majority of infestations originate in plants, begin your search in the yard. Look for fruit-bearing trees and ornamentals in particular, but don’t forget to thoroughly evaluate every plant, tree, and shrub in your yard as a result of your search.

If you come into a nest, use a stick to wrap it around and thread the silk around it as if you were creating cotton candy to keep it from falling apart.

Regardless of whether you have one or several nests, eradicating them is critical for treatment since this is where they dwell. If you have discovered Tent caterpillars or their nests, proceed with treatment as soon as possible.

Following your successful extermination of Tent Caterpillars from your yard, you need take precautions to ensure that they do not return. Check your landscape for re-emergence on a regular basis, and remove any egg masses that have accumulated in your ornamentals and fruit-bearing trees throughout the winter to prevent them from hatching in the spring. This is an excellent method of reducing their population before it becomes a problem. Early in the spring, be diligent in removing any nest or tent that you come across using a stick.

In order to maintain control, reapply every 90 days.

This is an excellent method of organically controlling their population while allowing the birds to perform all of the work.

Question: How To Keep Tent Worms Away

While tiny infestations may be controlled by dumping the nests into soapy water, contact pesticides are the most effective method for controlling bigger populations. Bacillus thuringiensis (Bt) is the most effective of the strains available. Because this is a selective pesticide, it only kills tent caterpillars while staying safe for use around other animals.

How do you stop tent worms?

Insecticides can be used on spider webs as a spot treatment to eliminate the infestation. Early morning or late evening applications are recommended in order to concentrate the spray on the tents when the caterpillars cluster.

If you want to keep eggs from hatching throughout the winter, spray them with dormant oil, which is a highly refined oil that distributes consistently and covers both dormant insects and their eggs.

What do you use to get rid of tent caterpillars?

For caterpillar infestations, a dormant oil spray applied to sensitive trees in late winter can prevent the eggs from hatching before the caterpillars emerge in early spring. Dried eggs, mites, scales, and other insects can be controlled by applying dormant oils to fruit trees over the winter.

What time of year do tent caterpillars come out?

The caterpillars hibernate as pupae in cocoons that are either concealed in the bark of trees or in the soil to protect them from the elements. The moths begin to emerge between the middle of March and the middle of late April. They are glossy white with brown wing dots on a white background. Female moths lay their eggs on the underside of leaves in masses ranging from 200 to 500 eggs in size after mating.

Can vinegar kill caterpillars?
