Understanding and Managing Boxelder Bugs: A Guide for Homeowners
As the seasons change, many homeowners find themselves dealing with unwelcome visitors—boxelder bugs. These pests, though relatively harmless, can be quite a nuisance when they invade homes in large numbers. At Spray Cool Pest Control, we’re here to help you understand these pests and provide effective solutions to keep them at bay.
What are Boxelder Bugs?
Boxelder bugs (Boisea trivittata) are small, black insects with distinctive red or orange markings on their backs. They are about half an inch long and are primarily found on boxelder trees, maple trees, and ash trees. While they are most visible in the fall and spring, they can become a year-round nuisance if they manage to enter your home.
Why Do Boxelder Bugs Invade Homes?

Boxelder bugs are attracted to warm areas and will seek shelter as temperatures drop. In the fall, they congregate in large numbers on the sunny sides of buildings and eventually find their way inside through cracks, gaps, and other openings. Once inside, they often settle in wall voids and attics, emerging when the weather warms up again.
Are Boxelder Bugs Harmful?
While boxelder bugs do not pose a significant threat to humans or pets, they can be a major annoyance. They do not bite, sting, or cause structural damage. However, they can stain surfaces with their excrement, leading to unsightly marks on walls, curtains, and furniture. Additionally, their sheer numbers can be overwhelming and unsettling.
Preventing a Boxelder Bug Infestation
Prevention is the best strategy when it comes to managing boxelder bugs. Here are some steps you can take to minimize the risk of an infestation:
- Seal Entry Points: Inspect your home for cracks and gaps around windows, doors, and foundations. Use caulk or weatherstripping to seal these entry points.
- Repair Screens: Ensure that all window and door screens are in good condition and free of tears or holes.
- Reduce Attractants: Boxelder bugs are attracted to boxelder, maple, and ash trees. Consider removing these trees from near your home, or regularly maintain them to reduce their attractiveness.
- Use Barriers: Apply insecticides around the perimeter of your home, focusing on potential entry points. This can help create a barrier that deters boxelder bugs.
Dealing with an Existing Infestation
If boxelder bugs have already made their way into your home, here are some tips for managing them:
- Vacuuming: Use a vacuum cleaner to remove boxelder bugs from indoor spaces. Dispose of the vacuum bag or empty the canister outside to prevent them from re-entering.
- Insecticidal Soap: For small infestations, insecticidal soap can be an effective treatment. Spray directly onto the bugs to kill them on contact.
- Professional Pest Control: For larger infestations or for a more comprehensive approach, consider hiring a professional pest control service. We have the expertise and tools to effectively manage and prevent boxelder bug infestations.
