Pesticide Application for Browntail Moth

The caterpillars of the browntail moth release tiny hairs that cause itchy rashes and sometimes respiratory distress. In July and August the moths can be seen on structures. They have a wingspread of about 1 1/2 inches and are strongly attracted to light. 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. Fall is a good time to plan for next year—learn about removing nests during the winter.
