Boxelder Bugs

 Boxelder bugs are considered nuisance pests. They do not sting or transmit disease, and are generally not known to bite, though there are rare reports of defensive biting. Boxelder bugs are not known to cause damage to dwellings or significant damage to plants. However, their feces will stain light colored surfaces when they are present. Smashing them can also release an unpleasant odor.
