Reminder: February is Browntail Moth
Awareness Month!
Please join us in raising awareness and taking action to reduce this pest's impact!
Not sure how to recognize or remove the webs? Follow the Four Rs below.
Learn to recognize if the trees where you live, work, and play have browntail winter webs.
|
 On sunny days, look for palm-sized webs on the tips of branches. Webs can look like a clump of leaves with white silk tightly around the leaf stem.
Use hand snips or extendable pole pruners to remove webs within reach of the ground and away from hazards such as powerlines.
In areas where hairs will be a nuisance or hazard, recruit professional help to treat webs on the property you own or manage. Licensed professional arborists employing lifts and climbers and FAA certified remote pilots with clipper-outfitted drones offer services to remove browntail webs in larger trees and shrubs in the winter. Licensed pesticide applicators may be able to use insecticides during the growing season to manage browntail moth.

In large, heavily infested trees like these oaks, removal of webs may not be practical because of the time and cost involved in this approach. In trees like this that are a concern from the standpoint of human health or nuisance, licensed pesticide applicators may be able to use insecticides to help reduce impacts from browntail caterpillars.
If you find browntail winter webs in your neighborhood, reach out and let your neighbors and town officials know. The more neighbors, businesses, and others that get together to respond to the problem, the better the results. Consider hosting your own browntail web clipping event in your neighborhood to reduce the itch for your family and your community!
