Why are they in my home and business?

If you are experiencing an outside infestation, it is due to the type of landscaping in your area. Boxelder Bugs are attracted to certain tree types and, unfortunately, the bugs might be coming from a tree up to two miles away! Boxelder Bugs tend to congregate on or near the sunniest or warmest side of homes and other buildings before infesting the interior. If they have infested your home or commercial building, they have found tiny openings to get in through. This could be a hole in a screen, or an unsealed crevice on the building itself.

Why should I treat for them?

Boxelders will cause major damage to landscaping around residential and commercial buildings. When they enter a building, they aren’t known for damaging structures. The main concern when they enter a structure is that they can be present in numbers ranging in the 1000s. It should be noted that this type of bug doesn’t reproduce in the structures it infests. Boxelders aren’t known to bite humans or animals, but their infestation can cause odors on draperies, linens and other surfaces from their fecal matter. When the Boxelder bug is crushed, it omits a foul-smelling odor.

How much service is typically required?

Once Boxelders have invaded your home, complete service is recommended. This type of insect is very difficult to remove from buildings once it gains access. Insecticides and maintenance/repair of any openings in a structure must be used.
