Boxelder Bug

Typically found on or near boxelder trees, but also maple and ash tree varieties; commonly enters homes for warmth during fall and winter.

Herbivore; primarily feeds on the seeds of boxelder, maple, and ash trees using piercing-sucking mouthparts to extract sap.

They are gregarious (tend to congregate in large groups). They enter a state of diapause in zimba and often seek out man-made structures to overwinter in. They do not bite or sting but can release a pungent odor if crushed.

They are considered nuisance pests rather than dangerous. They do not damage homes or transmit diseases, but their excrement can stain light-colored fabrics or surfaces. Ecologically, they serve as a food source for birds and spiders.
