Are Boxelder Bugs Dangerous?

Nope, not really. Boxelder bugs don’t bite, sting or transmit disease. They are relatively harmless bugs that, during the summer months, are often found on boxelder tress as well as maple and ash trees. Generally speaking, they only become a pest problem starting in late summer and extending through the fall. That’s because they seek out shelter from the cooling weather and often times that means they move into homes and businesses.

Homeowners may find excrement on walls, furniture, curtains and other items, but that damage is not really cause for concern. Especially not when you compare this pest to termites or mice.

Why Do I Have Boxelder Bug Problem?

Again it comes back to the time of year. To these bugs, your home or business offers the perfect place to spend the winter months. They’ll start by taking up space on the warm, sunny exterior of your structure and then make their way inside through cracks in the foundation or siding. Gaps around doors and windows also make access easy for these pests to invade.

You may also see boxelder bug activity in the spring when the weather warms up and these bugs move back outside.

How Can I Prevent Boxelder Bugs from Infesting in the Future?

The best way to prevent a boxelder bug problem is to keep these pests out by fortifying the exterior of your home. We recommend:

  • Sealing any cracks and crevices found in your home’s foundation
  • Caulking gaps around exterior windows and doors
  • Repairing any damage to siding or roof shingles.
  • Trimming trees or shrubs so that they don’t touch the exterior of your home or building.
  • Our Colorado’s Choice plan is a great option to keep boxelders and 20 other common pests out of your home

If boxelder bugs are a serious problem, you might consider removing boxelder trees and other seed bearing trees from your property or at least move them further from your house.

Great experience with the pest control service. Alexander did a thorough job spraying both the inside and outside of the home and took the time to explain what they were doing. I especially appreciated that he didn’t just treat the home but also pointed out areas around the house that could allow pests to get inside and recommended repairs and preventative measures to help keep them out. The service was professional, thorough, and informative, and I appreciated the attention to detail. I would definitely recommend them to anyone looking for reliable pest control and helpful advice from Alexander on preventing future pest problems.

Our garage had been infested with mice. They left quite a mess. EnviroPest has systematically worked to eradicated the mice, mitigate entry points, and most recently completed a thorough cleanup and sanitation process. Along the way, they have all been professional, friendly, and have gone out of their way to explain their findings and recommendations. I never felt like we were being upsold. Overall very satisfied and would call them again if needed.
