Boxelder Bugs

What do boxelder bugs look like?

Boxelder bugs are easily recognizable by the orange-red geometric markings on their backs.  They are often noticed in the fall as they begin to enter buildings in preparation for winter.  Though they do not spread disease, they can leave behind stains from their excrement, and are still a nuisance.

 

Do boxelder bugs bite?

No. Boxelder bugs are virtually harmless to humans, pets and plants.  But if you notice large numbers of them in or around your home, you should contact a pest control company like Ace Walco for service and they can put a quick end to the problem before they move in with you for the winter.  Read on for more information.

 

What damage do boxelder bugs do?

Boxelder bugs are mostly harmless, in that they do not bite or carry dangerous diseases.  However, their excrement can leave stains on various surfaces.  If they show up en masse, you should call an exterminator.  Luckily, treating a boxelder bug problem is quick and effective.

 

Habits

Boxelder bugs are active in the daytime and feed in and around their namesake trees, the boxelder.  They emerge and lay eggs in the spring, then gather in large groups in fall when they prepare to go inside for winter.  They like to gather on south or east-facing walls of buildings where the sun is warm.  Then they will gain access to structures through cracks, open windows or other entry points and live indoors until spring.

 

Habitat

Boxelder bugs live in trees, particularly their namesake, the boxelder tree, but they also live in ash and maple.  This is where they lay their eggs and feed throughout the spring and summer.  In winter, they live indoors.  They gain entry to a structure through exterior cracks and open windows.

Threats

Boxelder bugs do not bite or spread diseases, but they can leave stains from their excretion.
