It’s the same fungus New England arborists and scientists tried to spread a century ago. Pay close attention to your surroundings when outside and avoid places that are heavily infested with caterpillars. The Browntail moth is an invasive species found along the coastal regions of Maine.
The hairs on the caterpillars can float through the air on windy days. They lay eggs on the underside of leaves. You Can Kind of Tell. Though retired, Groden continues to work on the browntail project, alongside newly hired UMaine entomologist Angela Mech. The nests are much smaller than tent caterpillar nests. “You’re leaning out of the bucket to get each nest, and all the nests tend to be on the tips of branches.”. It has two broken white lines on each side of its brown body and two orangy-red spots on the end of its back. The list of signs and symptoms mentioned in various sources for Browntail moth caterpillar poisoning includes the 10 symptoms listed below: . Dry in the dryer. The breeze sent microscopic hairs drifting towards her face and left her itching for days, with welts that wrapped around her neck. The browntail moth caterpillar has tiny poisonous hairs that cause dermatitis, similar to poison ivy on sensitive individuals. Outbreaks have hit New England periodically since the first infestations were in recorded in the late 1890s, in Massachusetts, and the early 1900s, in Maine. For more information and resources on controlling and removing the population on your property, contact the Maine Forest Service.
“Now we know they are here, and they are probably not going away, unfortunately, until the natural cycle wanes.”. While there is nothing that will make the rash go away, there are a few different options for treatment which are focused on relieving symptoms and eliminating exposure.
The caterpillars are the larvae of browntail moths, notorious for the rash they cause when their tiny, toxic hairs contact human skin. Under the right conditions, it kills caterpillar bodies from the inside out and spreads rapidly by forming “fungal cannons,” inverted nipples that pop out when exposed to moisture, flinging spores into the surrounding environment. However, hairs can remain toxic for up to three years so it is possible for a reaction to be seen at other times throughout the year as well. Some people have severe allergic reactions to the caterpillar hairs.
Another option is to manually remove nests and burn them, as school kids did a century ago. These dots are one behind the other. Kennebec Pharmacy compounds a prescription spray that has helped many customers alleviate symptoms associated with browntail moth rash.

The easiest way to protect yourself and your loved ones are to know your risk and take the necessary precautions throughout the year to help limit infestation in your area. What scientists do know is that the caterpillars don’t sport their toxic hairs until emerging from their webs in late April, after growing through the winter. Larval feeding damages and sometimes kills the host, but the primary human impact from the browntail moth is the result of contact with poisonous hairs found on the caterpillars. The mention of pesticides in the fact sheets linked to these pages does not imply an endorsement of any product. “When you have a really high density [of caterpillars],” Groden says, “it just rips through the population.”. She’s optimistic about their ability to get more tools into the hands of arborists, who can help homeowners in critical areas, but she doesn’t see an end in sight for the caterpillars. She has just finished telling me, at length, about the dangers of touching these insects. And a state entomologist said Thursday that the worst conditions in … A dry spring has made for an itchy and scratchy summer along Maine’s coast, the result of a bumper crop of browntail moths. Their team is conducting experiments on how different environmentally friendly options — from essential oils to detergents to tiny pathogenic worms called nematodes — might weaken those protective winter webs, stopping the devastation before it emerges with the caterpillars in the spring.
In early to mid-July the moths break out of the cocoons and mate. They glisten in the sun. Keep car and house windows closed in high-risk areas. In late June the caterpillars spin cocoons. The chance of contacting browntail moth rash increases during dry, windy conditions. Once they’re out, they devour leaves (in high enough numbers, they can denude a single tree in weeks) and continue growing larger and more toxic until late June, when they build cocoons and prepare to transform into harmless white moths.
The fibers that they molt remain toxic for up to 3 years. It has recently become a big problem in coastal Maine. Be wary opening up camps in infested areas because the fibers settle out of the air over the winter (which I think may have been a factor in my case).

The caterpillars are the larvae of browntail moths, notorious for the rash they cause when their tiny, toxic hairs contact human skin. Towns paid bounties for the nests, which school children collected by the bushel and piled into truck beds to be transported to furnaces and burned. Some people also have breathing problems from inhaling the hairs. Ste. In recent years, populations of these caterpillars have exploded in pockets of Maine, notably around the midcoast and Merrymeeting Bay, although they’ve been found along the coast from Kittery to Mount Desert Island and as far inland as Corrina. In late August the larvae hatch from eggs laid on the undersides of leaves and form overwintering webs in trees and shrubs. At Kennebec Pharmacy and Home Care, we are dedicated to making better living possible for the people we serve. Maine Center for Disease Control and Prevention has created a new service for Mainers to speak to a specialist about browntail moth issues, including biology, management, pesticide options, health concerns, reducing toxic hair exposure, and potential public policy and economic impacts. It is the policy of the State of Maine to minimize reliance on pesticides. Jesse Wheeler, exotic plant program coordinator at Acadia National Park, took this approach after a visitor spotted a few webs last year, the first of this outbreak.

The most promising countermeasure to emerge from the UMaine team’s research is a naturally occurring fungus, Entomophaga aulicae, that proves lethal to browntail caterpillars but relatively benign to the rest of the ecosystem. The Maine Department of Agriculture and the Maine IPM Council encourage everyone to practice integrated pest management and to use pesticides only as a last resort. Browntail moth caterpillars are active from May-July which is when most rashes occur.
The rash often appears on skin inside the elbow, around the waist or on the neck.

This prompted the city to prune and spray nests with pesticides, both as a public safety precaution and to protect the city’s heritage oaks, says Ethan Hipple, deputy director of Portland’s Department of Parks, Recreation and Facilities. Wings and midsection are pure white while the abdomen (rear part of the body) is brown with a conspicuous tuft of brown hairs at the tip. It’s similar to an allergic reaction to poison ivy — blistery, irritating, and all-too-familiar to an increasing number of Mainers. The caterpillars prefer Oak and Apple trees. These dots are one behind the other. Prescriptions can generally provide relief with one bottle as opposed to using multiple lotions, creams, or sprays. The work doesn’t come without discomforts, though: researchers on Groden’s team regularly end up with rashes after tromping through the woods or even leafing through field notes back at the lab. Urticaria; Skin rash; Conjunctivitis Most individuals affected will notice signs after outdoor activity where they have been exposed to trees or shrubs that are home to the pests or from wearing clothing that has been exposed to airborne hairs. Browntail Moth Rash, also known as Browntail Moth Itch, occurs after coming into contact with the poisonous hairs shed by browntail moth caterpillars. The browntail moth larva has prickly hairs covering its body. In a sense, the team is the only line of defense — since the pests currently plague no other state (just a few isolated spots on Cape Cod), they aren’t a priority for many other researchers in the country. The larval stage (caterpillar) of this insect feeds on the foliage of hardwood trees and shrubs including oak, shadbush, apple, cherry, beach plum, and rugosa rose.
