How to Eliminate Boxelder Bugs from Indoor Spaces

 

Boxelder bugs are black insects with red or orange markings that often enter homes as the weather gets colder. They do not bite or cause significant property damage, but they can become a real nuisance, especially in large numbers. To get rid of boxelder bugs indoors and prevent future invasions, you’ll need to remove any currently present, block their entry points, and reduce any attraction factors.

 

Remove Boxelder Bugs Currently Inside

 

• Vacuuming: Use a regular vacuum cleaner to suck up boxelder bugs you see indoors—on windows, walls, or other surfaces. Immediately empty the vacuum bag or canister outdoors to prevent bugs from crawling back out.
• Manual Removal: You can also pick up bugs with a tissue or paper towel and flush them down the toilet or discard them outside, far from your home.

 

Seal Entry Points to Stop Their Return

 

• Windows and Doors: Examine all windows and doors. Make sure weatherstripping and door sweeps are intact and properly placed. Repair or replace damaged parts.
• Cracks and Gaps: Look for cracks around your foundation, window frames, siding, and where utilities enter your home. Use silicone caulk to seal small gaps and expandable foam for larger holes.
• Screens: Repair or replace any torn window or door screens so boxelder bugs can’t sneak in.

 

Reduce Attractants Inside Your Home

 

• Light: Boxelder bugs are drawn to warmth and light. At night, keep curtains or blinds closed and try to minimize leaving lights on unnecessarily, especially near doors and windows where bugs could get in.

 

Safe Indoor Solutions

 

• Soap and Water Spray: Fill a spray bottle with soapy water (a small amount of dish soap mixed in water). Spray directly on bugs; it will kill them without the need for harsh chemicals.
• Avoid Insecticides: Most over-the-counter indoor insecticides are not especially effective against boxelder bugs and can be harmful to pets or people if not used correctly.

 

Discourage Future Invaders from Gathering Outside

 

• Boxelder and Maple Trees: Boxelder bugs feed on boxelder, ash, and silver maple trees. If these are close to your home and are causing major problems, consider consulting an arborist about managing these trees—though removal is a drastic step.
• Yard Debris: Rake leaves and remove plant debris near your foundation to reduce outdoor gather spots.

 

What to Avoid

 

• Don’t Crush Them: Crushing boxelder bugs inside releases a strong, unpleasant odor and can stain walls, curtains, or furniture.
• Don’t Rely on Traps: Sticky traps may catch a few but are ineffective at solving large infestations.
• Don’t Use Exterior Sprays Without Professional Advice: Some perimeter sprays are toxic and need professional application; improper use can harm your health and the environment.

 

When to Call a Professional

 

If you consistently find large numbers of boxelder bugs inside despite these steps, or if sealing entry points is difficult due to your home’s design, consider hiring a pest control technician. Professionals can pinpoint access points you may have missed and safely apply effective, targeted treatments.

 

Summary

 

Boxelder bugs are pesky but harmless. The best way to remove them from indoor spaces is to vacuum or sweep them up, seal all cracks and gaps in your home, fix screens, and use mild soap sprays if needed. Prevent future problems by reducing outdoor attractions and keeping your home well-sealed. Avoid crushing bugs indoors and only use pesticides or tree removal when absolutely necessary or when advised by a professional. By following these steps, you can effectively keep boxelder bugs out of your indoor spaces and prevent future infestations.
