Boxelder Bug / Beetle
- Color: Black with reddish lines on its wings that form an inverted V when at rest.
- Body Size: About 1/2 inch long.
- Found: Boxelder bugs get their names because they are a major pest of boxelder trees. They become a nuisance pest when they congregate on the exterior of structures, sometimes in great numbers, then enter between cracks and crevices in walls and siding. These overwintering adults may emerge into homes during the winter. Their fecal matter can then stain curtains, drapes, clothing, and surfaces on which they rest. They also may occasionally bite.
