These pests get their name from their reputation for living around boxelder trees and are common in central and eastern areas of North America. The Boxelder Bug is an insect with the shape of an elongate oval, primarily black coloring, and reddish or orange markings. They are not dangerous but are a nuisance when they infest homes, sheds, garages, etc. The more effective prevention method is to seal holes and cracks in the home, especially exterior features. If an infestation is already underway, a licensed pest control professional is the best resource for inspection and treatment.
