Boxelder Infestation

Boxelder bugs can be a nuisance in certain homes, particularly those with boxelder trees in the yard. When the winter months are approaching, these bugs will seek entrance into the home or underneath a building's siding. As they desire warmth, homes with increased sun exposure are typically more likely to experience a boxelder bug infestation. Once inside, they hibernate until spring, though a home's heating system can spur the insects to activity sooner than natural.

A boxelder bug is rarely anything more than inconvenient. They do not pose any health concerns and almost never bite humans. They also lay their eggs exclusively outdoors. These pests can, however, stain curtains and other fabrics with their excrement, and they release an unpleasant odor into the air when crushed or threatened.
