How to Get Rid of Boxelder Bugs

A closeup of a boxelder bugBoxelder bugs, named for their diet of boxelder tree seeds and leaves, are black insects with reddish or orange markings on their back. Adult boxelder bugs are about a half inch long with an elongate-oval body. Nymph boxelder bugs look like adults but are smaller, bright red with little to no black, and do not have wings.

While boxelder bugs are native to the western United States, they can be found from eastern Canada through the eastern U.S. and west to eastern Nevada—wherever boxelder trees are found.

What Causes Boxelder Bugs?

Boxelder bugs are considered nuisance pests. They are known to enter structures, including homes, sheds, and garages in the fall to survive chilly winter weather. Homeowners may spot these pests once winter ends and the boxelder bugs leave to reenter the outdoors. Even though boxelder bugs do not pose a threat to humans, many people still want to know how to get rid of boxelder bugs, and why you shouldn’t try to kill them.

How to Get Rid of Boxelder Bugs — Inside and Outside in Your Home

Getting rid of boxelder bugs outside your house starts with first eliminating any potential points of entry. Repair holes in door and window screens, seal crevices and cracks with caulk and install door sweeps to all exterior entrances.

When removing boxelder bugs, avoid outright killing them, especially if they have already entered your home. That’s because killing boxelder bugs results in dead insect bodies that attract hungry dermestid beetles in search of food. Instead, you can get rid of boxelder bugs by using a vacuum cleaner. After vacuuming, remove the bag before they escape. Then, seal up points of entry around the exterior of your home to prevent a future infestation. But keep in mind that pest experts recommend waiting until the summer when all the overwintering adults have left the structure.
