WINTER MOTH WORKSHOP
Late October is a great time to learn about winter moths and prepare for their arrival. Adult winter moths typically become active in late November and can remain active through January whenever temperatures are above freezing.
Winter moth larvae feed on many of Maine’s deciduous trees and shrubs, including oak, maple, apple, elm, ash, crabapple, cherry, and blueberry. Repeated heavy infestations can lead to branch dieback and even tree mortality.
Join the City of Bath and the Bath Community Forestry Committee for a free community workshop to learn how to identify signs of winter moth infestation and help protect Bath’s trees and shrubs.
Wednesday, October 21
9:00 AM
BCFC Nursery at Oak Grove Cemetery
Enter from Old Brunswick Road at the Oak Grove Cemetery entrance, just past the middle school when leaving town.
During this hands-on workshop, participants will learn about:
• Signs of winter moth infestation
• Risks to trees in our community
• Integrated pest management strategies
• Using sticky trap barriers to help manage adult winter moths
The workshop is free and open to the public, and no registration is required. It will run for up to two hours.
Parking is available at the nursery and along the cemetery access road. Handouts will be available to take home, along with additional resources from the Maine Forest Service.
