How to Get Rid of Boxelder Bugs
Boxelder bugs are a fall problem you see coming. On warm autumn days they gather by the dozens on the sunny side of the house, then look for any crack to slip inside and wait out winter in the walls. The move is to treat the outside before they pile in, which is exactly what the kit does.
How to identify them
Adults are about half an inch long, black with three orange-red lines behind the head and orange-red edges along the body, and their wings cross flat on their backs. You will spot them in clusters rather than one at a time. Do not crush them indoors, they leave a stain and a foul smell.
Where they hide
In fall they cluster on south- and west-facing walls, siding, and around windows and doors, following the warmth. From there they push into gaps under siding, eaves, soffits, and vents to overwinter in wall voids, then reappear in spring.
Why it matters
Boxelder bugs do not bite, sting, or damage the structure, so the problem is the sheer numbers. They stain siding, curtains, and surfaces with their droppings, and crushing them leaves a lasting odor. Once they settle into wall voids in fall, they keep reappearing indoors through the winter, which is why treating early matters.
How to get rid of them
Timing matters. Treat the exterior perimeter in late summer and early fall, before they migrate inside, focusing on the sunny south and west walls, the eaves and soffits, and around windows and doors. A residual perimeter spray on those surfaces kills the bugs on contact and keeps working as more arrive. For the few that already made it indoors, vacuum them up rather than crushing them.
