Box Elder Bug Behavior
In their proper habitat, Boxelder Bugs inhabit ash, maple and seed-bearing Boxelder trees, feeding on soft plant tissues, leaves, and flowers.
The main concern with Boxelder Bugs in our area is that they have no major known predators, which allows their reproduction rate to get out of control if left untreated. In Spring they can swarm and cover the warm sides of houses and buildings by the hundreds of thousands, literally covering the entire surface.
When the colder weather arrives and they seek the indoors. Boxelder Bugs become a major nuisance and health hazard inside our home, commercial, and industrial properties. The primary health concern comes from the excrement they leave behind on curtains and other interior surfaces.
