Boxelder bugs, Boisea trivittata, got their household name because their favorite habitat is on or around boxelder trees. Box Elder bugs are native to the western United States, but can be found throughout Canada and the eastern United States, essentially wherever boxelder trees can be found. Boxelder bugs are known as a nuisance pest because they do not pose any real threat to humans. They simply invade domiciles and garages to avoid the winter chill.
Boxelder bugs are entirely black, however, they have distinct orange or red markings across their backside. Full grown adult Box Elders are roughly half an inch long and have a unique ovular shape. Box Elders have two antennas they use to perceive their surroundings, and they skitter around on six small legs. The female Box Elders resemble the males body shape but are entirely red and do not have any wings.
Box Elder bugs are typically not an issue until they begin to invade homes and garages during the winter. Unfortunately, most homeowners are unaware of their presence until spring cleaning time when the traces of their presence are typically uncovered. The best practice is to hire recurring pest control services to maintain a preventative line of defence against these pesky invaders
