How to Get Rid of Tussock Moth Caterpillars Naturally: Effective and Eco-Friendly Solutions

Tussock moth caterpillars are native insects that can suddenly become quite abundant in some areas. These hairy creatures are known to feed on certain types of trees, including oak trees, causing damage to foliage. Dealing with them naturally can help protect your plants, trees, and natural surroundings.

There are several methods for controlling tussock moth caterpillar populations without resorting to chemicals or pesticides. These natural techniques are aimed at preserving the environment while ensuring the health and beauty of your greenery.

Some natural methods include:

  • Introducing beneficial insects like ladybugs
  • Removing caterpillar-infested branches and leaves
  • Creating physical barriers to prevent access to plants

Identifying Tussock Moth Caterpillars

Tussock moth caterpillars can be easily identified by the following features:

  • Hairy body
  • Red head
  • Light-colored tufts of hair along the back
  • Red spots on top
  • Orange stripe along each side

These distinctive features help distinguish them from other caterpillars, such as the rusty tussock moth1.

Tussock moth caterpillars are typically found during the summer months, when they feed on leaves. They hatch from eggs laid by adult moths in spring2.

Caterpillars vs Moths:

Characteristic Caterpillars Moths
Stage Larvae Adult
Feeding Yes No
Appearance Hairy Winged

One helpful characteristic for identifying tussock moth caterpillars is their hairy appearance. In particular, the tufts of hair on their back are unique to this type of caterpillar. Additionally, the red spots and orange stripes can serve as reliable identifiers.

In conclusion, if you notice caterpillars in your garden or on your trees with the aforementioned characteristics, it is likely that you are dealing with tussock moth caterpillars.

Life Cycle and Feeding Habits

Tussock moth caterpillars go through a life cycle that starts with eggs laid on leaves or cocoons in spring. Once hatched, tiny hairy caterpillars begin to feed and grow1. These caterpillars can inflict significant damage to plants due to their strong appetites2. Adult moths fly and lay eggs around May-June3.

For example, the feeding habits of two common tussock moth caterpillars:

  • Milkweed Tussock Moth Caterpillars2: They feed in clusters during early instars, causing damage to milkweed plants.
  • Hickory Tussock Moth Caterpillars3: They feed in groups during their early stages and become more solitary as they grow.

Tussock moth caterpillars mostly infest trees and plants during spring, and their larvae can spread using silk strands4. To manage the infestation naturally, introduce Bacillus thuringiensis5, a soil-dwelling bacterium, to your garden or shrubs. It’s an organic method of eliminating the caterpillars without causing damage to plants.

Pros and Cons of using Bacillus thuringiensis:

Pros Cons
Organic and safe for plants May need multiple applications
Targets caterpillars specifically Not effective against adult moths

In summary, understanding the life cycle and feeding habits of tussock moth caterpillars can help develop effective strategies for managing infestations in gardens and keeping trees and plants healthy.

Natural Control Methods

Biological Controls

One effective way to control tussock moth caterpillars is by introducing beneficial insects in your garden, such as:

  • Predatory insects: Parasitic wasps and lady beetles can help control tussock moth caterpillar populations.

  • Birds: Encouraging birds to visit your garden by providing food, water, and shelter can also help control these pests.

  • Bacillus thuringiensis (Bt): A naturally occurring bacterium, Bt is effective against tussock moth caterpillars when ingested. Apply Bt on affected plants, but note that it can harm butterflies as well.

Physical Removal

Physically removing tussock moth caterpillars involves:

  • Handpicking: Wear gloves and collect the caterpillars from your plants.

  • Traps: Use sticky traps or pheromone-based traps to catch adult moths and reduce their reproduction.

Natural Pesticides

Using natural pesticides can provide an effective and environmentally friendly solution for controlling tussock moth caterpillars. Some options include:

  • Neem oil: Derived from the neem tree, this natural pesticide can be applied to affected plants to deter caterpillar feeding.

  • Pyrethrins: Extracted from chrysanthemum flowers, pyrethrins are insecticidal compounds that can be used as a natural pesticide.

Method Pros Cons
Biological Controls Targets specific pests, eco-friendly May take time to establish
Physical Removal Immediate action, no chemicals Labor-intensive, may not be feasible for large infestations
Natural Pesticides Less harmful to the environment, pollinators May require multiple applications, potential harm to beneficial insects

Remember to be cautious when using any control method, as some can harm beneficial insects, birds, and pollinators such as bees and butterflies. A combination of these natural control methods can provide an effective and eco-friendly way to manage tussock moth caterpillar populations in your organic garden.

Prevention and Maintenance Strategies

To keep your garden safe from tussock moth caterpillars, adopt these preventative and maintenance strategies:

  • Inspect your trees and plants regularly, especially in spring when the caterpillars are most active.

  • Wear gardening gloves when handling plants, as the caterpillars’ hairs can cause skin irritation.

  • Remove and destroy cocoons found on trees or near your house.

  • Introduce beneficial insects like ladybugs or lacewings to your garden, which can naturally reduce caterpillar populations.

  • Consider planting sage, as it is known to deter many pests.

Methods/Products Pros Cons
Inspections Early detection May be time-consuming
Ladybugs Natural pest control Small impact
Sage plants Easy to care for Effectiveness varies

Preventing tussock moths and caterpillars helps maintain the overall health and appearance of your landscape. Remember to stay vigilant, and keep your gardening gloves handy.

Safety Considerations and Tips

When dealing with tussock moth caterpillars, safety is important for both humans and the environment. Here are some guidelines and tips to keep in mind:

Non-toxic methods:

  • Soapy water can be an effective and non-toxic method to remove tussock moth caterpillars. Combine water and a few drops of dish soap in a spray bottle, then spray it directly on the caterpillars.
  • Neem oil is another natural option that can help control these pests. However, be sure to follow the label instructions and avoid contact with skin, pets, or children.

Protective gear:

  • Wear gardening gloves when handling caterpillars to prevent itching and rash.
  • Use tweezers or a broom to remove the pests without directly touching them.

Watch out for beneficial insects:

  • Be cautious not to harm beneficial insects, such as ladybugs or bees, while treating for tussock moth caterpillars. They can help keep the population in check and maintain a healthy garden ecosystem.

Here’s a comparison table for some popular natural methods:

Method Pros Cons
Soapy water Non-toxic, easily available May not affect all caterpillars
Neem oil Natural, effective Can be harmful if not used properly

Remember to be cautious and always prioritize safety when dealing with tussock moth caterpillars. Keep pets, children, and beneficial insects in mind while implementing any control methods.

Western Tussock Moth Caterpillar

Hi Rolf,
Your Western Tussock Moth Caterpillar,
Orgyia vetusta, shares many similar characteristics with its close relatives in the genus.  BugGuide only reports this species from California, though its relatives including the White Marked Tussock Moth, Orgyia leucostigma, are found throughout North America.  You should handle the Western Tussock Moth Caterpillar and its relatives with caution because BugGuide notes:  “Contact with hairs may cause an allergic reaction.

Dear bugman,
Earlier today, we had a caterpillar sitting for hour on the exterior wall next to our apartment’s door. I eventually scooted a piece of paper underneath it and repatriated it to the front of the building, primarily to appease my wife and also to protect it from other tenants smashing it.  Nevertheless, I am curious what it was that we saw there.
Thank you very much for your time and effort,

Dear Carol and Roland,
We are guessing from your combined requests that you are a married couple.  We think it is sweet that you each contacted us, and in an odd way, it reminds us of the “Starbucks scene” in Best in Show where Parker Posey and Michael Hitchcock meet at Starbucks, but at different Starbucks across the street from one another.  This is a Southern Tussock Moth Caterpillar, 
Dasychira meridionalis, or another member of the genus, and you can compare your caterpillar to this photo from BugGuide.  Some Tussock Moth Caterpillars have irritating hairs, but we are not certain if this is one of those species.

Letter 5 – White Marked Tussock Moth Caterpillar

identify this picture

Despite being annoyed at the terse demanding tone of this query, we are posting a relatively lengthy answer, however our personal reply was equally brief. This is a White Marked Tussock Moth Caterpillar, originally Hemerocampa leucostigma and now identified as Orgyia leucostigma. It is a pest on most shade and ornamental trees. They can become so numerous that they defoliate trees. Though the caterpillar is quite beautiful, the moth is small and inconspicuous.

Dear Mikala24,
This is either a White Marked Tussock Moth Caterpillar,
Orgyia leucostigma, or a closely related species in the same genus.  According to BugGuide:  “CAUTION: Avoid handling the caterpillar, as its hair is known to cause allergic reactions, especially in areas of the body with sensitive skin (e.g. back, stomach, inner arms). Seek medical treatment if a severe reaction occurs.”

Letter 7 – Flightless Female Western Tussock Moth and Egg Mass

 

Subject: Unknown Bug
Location: California Bay
November 20, 2012 11:30 pm
Hello there. There are these strange looking bugs that have been seen near where I live (Pacifica and San Bruno California) and I have no idea what they are. Can anyone identify them? I’ve never seen anything like this before!
I’ve seen more than one now, they are very hairy and squishy. They have at least 4 or 6 legs (near their head) and they are always attached to a hairy sack with a hallow black exoskeleton inside and next to what looks like an egg sack. They have wing-like appendages that are small and hairy near their heads.
Signature: Alexsis Johansen

Flightless Female Western Tussock Moth with Egg Mass

Dear Alexsis,
Your description is perfect and it could not be more accurate.  This is a flightless female Western Tussock Moth,
Orgyia vetusta, and we identified it on the Moth Photographers Group Flightless Females page, but there is even more information on the Moth Photographers Group Tussock Moth Parasitoids page that documents the life history as well as a significant parasitoid predator, a species of Tachinid Fly.  According to Joyce Gross of the University of Berkeley:  “Adult females are wingless. When they emerge from the cocoon (eclosure) they remain upon it and release a pheromone, a sex-attractant that brings males to her. The large antenna of the male is very sensitive to the species-specific pheromone and any males downwind of the female will quickly follow the scent to her location.”  There is also a very nice photo on BugGuide of a newly emerged female.  You can see photos of the caterpillars of the Western Tussock Moth in our archives.

Update from November 22
Now that I have viewed the website I have realized that I have been seeing those western tussock moth caterpillars my whole life and I never would have guessed they would turn into that moth! That is truly amazing. Here is a photo that I took of the caterpillar a few months ago. Thank you so much for your response!

Hi Alexsis,
More than a week has passes since you submitted the caterpillar photo, but we were away for Thanksgiving, and there is way more mail in our inbox than we can read.  We are updating the posting with your new photo.

 

Letter 8 – Probably Western Tussock Moth Caterpillar

 

Subject: unknown tussock moth caterpillar

Friends who live in Napa California recently photographed this caterpillar on their property.
After going through your caterpillar pages, we concluded it was a tussock moth caterpillar but couldn’t match the color pattern with any of the species shown. The closest seems to be that of the
Western Tussock Moth. What is your identification of this caterpillar?
Signature: Mike Walsh

Probably Western Tussock Moth Caterpillar
Probably Western Tussock Moth Caterpillar

Dear Mike,
There are several species of Tussock Moths in the genus
Orgyia that are found in California, and we believe this is most likely the Caterpillar of the Western Tussock Moth, Orgyia vetusta, but it may be impossible to determine the exact species with an image since all members of the genus have very similar looking caterpillars and there is also much variation within the species.  See this BugGuide image for comparison.

Letter 9 – Western Tussock Moth Caterpillars

 

Pacific Tussock Moth
I’m just one of those people who work at the Exploratorium who loves your site, so I thought you might like to see an invader that concerned me earlier this year. The caterpillar in question was eating all the ground cover over a large area on the side of the hill where I live on Mount San Bruno, just south of San Francisco. Here’s what it looked like on the human-scale: Note the brown eaten area. Not a leaf left! I consulted a local expert and he informed me that the culprit was the Pacific Tussock Moth, Hemerocampa vetusta, which I couldn’t find in your collection of caterpillars, so here you go – a small portion of the MILLIONS that were out there: And a close-up: Keep up the good work!
Ron

Hi Ron,
Thank you for the nice letter. As you stated, this is a new species for us. We always like to research new species. We did locate a caterpillar on BugGuide that looks identical to yours that is identified as the Western Tussock Moth Caterpillar, Orgyia vetusta. The genus formerly known as Hemerocampa is now recognized as Orgyia. Thank you for the images.

Letter 10 – Western Tussock Moth Caterpillar

 

Unknown caterpillar?
Hi there!
We were watering the plants in the yard and came across three of these on our geranium and one on our rosebush. We live on the central coast in California and have never seen these in our yard. The closest match we could find is the White Marked Tussock Moth Caterpillar. Watcha’ think?
Thanks,

Dear Vera,
This appears to be the caterpillar of a Western Tussock Moth,
Orgyia vetusta, which is pictured on BugGuide.  BugGuide makes no mention of irritation caused by the hairs, but other members of the genus including the White Marked Tussock Moth are known for having urticating hairs.  Of that species, BugGuide notes:  “CAUTION: Contact with hairs may cause an allergic reaction.”  According to the Moth Photographers Group:  “Dozens if not hundreds of these caterpillars have been busy eating leaves on a Coast Live Oak.”

Your letter to the bugman:  We were curious as to who this is. Having grown up in TX, my husband knew all about urticating hairs; hence the stick! Better safe than sorry. It was near fir, pine, sarviceberry, chokecherry, wild roses and currant for the bigger forage plants we have. Other than that, it’s a real dry climate. Thanks.

Western Tussock Moth Caterpillar

Dear Cathy,
Your subject line caught our attention because of the mohawk description.  Based on its color and markings and your location, we believe this is a Western Tussock Moth Caterpillar as pictured on BugGuide, but we would not rule out a similar looking relative in the same genus.  Handle Tussock Moth Caterpillars with caution.  The hairs might cause a skin reaction in sensitive individuals.

As I was a “bug queen” for a day a few years ago on WTB, I thought I would ask about something I’ve never seen before.
The enclosed pics are of the siding in my house. There appears to be a “nest” to the left of a white moth. However, I did NOT see any wings on this “moth.” The nest had soft dried grass to the left, but the white part to the right was hard like plastic.
Would appreciate some bug love with an answer as to what my new critter friend is.

  1. Hi,
    Just came on this web site. I also have this white marked tussock moth caterpillar all over my hop plants. I also am a home brewer. These hops have been here for 5 to 10 years and this is the first year I have seen them and they are very abundant, so I am highly confident they came from some other source as we have an extensive garden. We live in central Michigan 5 miles north of East Lansing in Bath. I wonder what adverse affects they have caused since this post is 2 years old.
    Thanks Tom D.
