These caterpillars are poisoning people in Maine, causing painful rashes

Another insect is wreaking havoc in Maine in the midst of the cicada's invasion – a poisonous caterpillar.

The browntail moth caterpillar has been seen in multiple counties in Maine and is an invasive species found only there and in Cape Cod. The hairs of the moth contain poison and can cause a reaction similar to that of poison ivy, according to the Maine Center for Disease Control and Prevention.

“People are finding them everyplace: on the ground, on the picnic table, on the electrical box, on the corner – you name it," Jim Britt, spokesman for the Maine Department of Agriculture, Conservation and Forestry, told The New York Times.

The caterpillars are 1½ inches long, are dark brown with white stripes and have two orange dots on their backs.

The caterpillar's hairs can go airborne. When they contact a person’s skin, they can cause a rash that lasts several hours, or for those with sensitive skin, the rash can last several weeks.

If the hairs are inhaled, respiratory distress can be serious, state health officials said.

The Maine Center for Disease Control and Prevention declared the critter a public health nuisance, and the city of Bangor said in a Facebook post that it was formulating a plan to address the infestations popping up around the city and other locations.

Amanda Umble told Bangor Daily News she didn’t recall coming into contact with one when she broke out in a rash on her forearm.

“It feels like you have bugs in your bed,” Umble said. “It feels like things are on me the whole night biting me.”

Umble told the newspaper she tried Benadryl cream, then tried Cortisone 10, which worked better to clear her rash up after about a week. There are no specific treatments for the rash, but experts say a cool bath with baking soda, hydrocortisone cream and calamine lotion can help.

State officials said this year's invasion may have worsened because of a warmer spring.

Several municipalities have advised residents to wear goggles, take cool showers and dry laundry inside until after summer.

Maine isn't the only state seeing an increase in caterpillars this season. Vermont is experiencing its worst outbreak of leaf-munching gypsy moth caterpillars since 1991, according to state foresters.
