Winteris Coming

摘要

You know about occasional invaders—those outside perimeter pests like earwigs, pillbugs, millipedes and crickets — that occasionally find their way inside. There's a subset of occasional invaders that can be called fall invaders. These are the peststhat enter buildings in the fall as the weather cools, with the intent of finding a sheltered place to spend the winter. Some of our most problematic overwintering fall invaders are the Asian lady beetle, brown marmorated stink bug, boxelder bug, elm leaf beetle, cluster fly and paper wasps.
