As temperatures drop, overwintering pests — boxelder bugs, stink bugs, Asian lady beetles, and cluster flies — seek warm shelter inside the walls and attics of your home. Once they’re in, they’re hard to remove and reappear all winter and spring.
The key is timing. A targeted exterior treatment applied in early fall, before they move in, creates a barrier on the sunny exterior surfaces these pests gather on — stopping the invasion before it starts.

Frequently asked questions
Late summer to early fall, before the first cold snap drives invaders toward your walls. Once they’re inside, treatment is far less effective.
Pests that overwinter inside wall voids re-emerge as it warms. Treating in fall prevents them from settling in to begin with.
DIY methods (vacuuming, soapy water) handle bugs you can already see, but they don’t stop the next wave from moving into your walls. A professional exterior treatment applied at the right time targets the gathering spots before that happens.
