Are You Expecting Boxelder Bugs To Show Up Soon?

Did you notice anything unusual happening on the outside of your home last fall when the temperatures began to drop? Perhaps you saw several black bugs with distinctive red and orange markings hanging out on the sunny side of your home or business? If so, were you concerned? After all, what harm can a bunch of relatively pretty boxelder bugs do while warming themselves in the sun?

Unfortunately, boxelder bugs don’t stay outside

The problem with boxelder bugs on the outside of your structure in the fall is that they will not be content to stay there as temperatures dip lower and lower. You see, these insects are cold-blooded creatures that need to stay where it is warm. If they get too cold, they will die, which is why they move inside heated structures in the fall. 

If they found their way in last fall and spent the winter in your attic or wall voids, there’s a good chance they’ll do it again this fall. 

How can you prevent boxelder bugs from infesting your home?

There are several steps you can take to prevent a boxelder bug infestation in the future. Doing the following will not only keep boxelder bugs out, but will help keep many other pests out as well.

  • Carefully inspect the outside of your home for gaps, cracks, or holes. Seal these areas by using a caulking gun. Pay special attention to areas around pipes, wires, air conditioning units or any other item that pass through your exterior walls.
  • Seal any gaps around exterior windows and doors.
  • Check areas where different building materials meet, such as siding and brick, and make sure there are no gaps.
  • Check all your screens and door sweeps and repair or replace any that are damaged or absent.
  • Install or replace screens in roof and soffit vents.
  • Inspect your walls and roof and replace or repair damaged siding or roof shingles.
  • Make sure all trees and shrubs are trimmed back away from your home or business.
  • If you have box elder trees on your property, consider removing them. If you plan to add box elder trees to your yard, consider choosing male (non-seed bearing) trees, since female box elder trees are more susceptible to infestation.
