Browntail moths are expected to terrorize Maine again if we don’t get more rain

BANGOR DAILY NEWS • May 12, 2022

Bad news for Mainers: It’s likely to be another bad season for browntail moths. While Mainers have been enjoying picturesque, sunny spring weather in recent weeks, it’s not the type of weather that will help reduce browntail moth caterpillar populations ― and the tree defoliation and rashes they cause ― in coming months. Forest insect experts predict that this year’s browntail moth conditions will be as bad as last year ― the worst Maine has ever experienced ― unless more rain falls in the next month and a half to help bolster the spread of diseases that kill the caterpillars.
