Boxelder Bug Control in Summerville

Frequently Asked Questions

When Are Boxelder Bugs Most Active and Likely to Infest Homes in Summerville?

Boxelder bugs are most notably active and prone to infesting homes in Summerville during late summer and particularly in the fall, as cooler temperatures signal their need to find overwintering sites. They are attracted to warm, sunny surfaces, often congregating in large numbers on the south and west-facing sides of homes before attempting to squeeze through cracks and crevices to seek shelter inside wall voids, attics, and other protected areas for the winter. While adults emerge in spring to feed and reproduce on boxelder and sometimes maple trees, it's their mass migration indoors during the autumn that makes them a prominent nuisance for homeowners.

How Do Boxelder Bugs Get Inside My House?

Boxelder bugs typically gain entry into homes through very small openings, seeking warmth and shelter as outdoor temperatures drop. They can squeeze through tiny cracks in foundations, gaps around window and door frames, unscreened vents, and even through openings where utility lines enter the house. Any unsealed or poorly sealed crevice in the exterior of your home, including those around fascia boards, soffits, and siding, can serve as an invitation for these persistent pests to invade and find suitable overwintering spots within your walls, attics, or basements.

Do Boxelder Bugs Cause Damage to Homes, Plants, or People?

While boxelder bugs are primarily considered nuisance pests, they generally do not cause significant damage to homes, plants, or pose a direct threat to people. They are not known to bite or sting, nor do they transmit diseases. On plants, their feeding on seeds or leaves of boxelder, maple, and sometimes fruit trees can occasionally lead to minor leaf discoloration or misshapen fruit, but this is rarely severe. The main complaint homeowners have is the reddish or brownish stains their excrement can leave on light-colored surfaces like curtains, walls, or upholstery if they are crushed or congregate in large numbers indoors.

How Long Does Boxelder Bug Control Last, and Will They Come Back?

The longevity of boxelder bug control depends on the thoroughness of the treatment and ongoing preventative efforts. Professional treatments targeting existing populations and sealing entry points can provide significant relief, often lasting through the overwintering period. However, boxelder bugs are strong fliers and can travel from nearby host trees, meaning that new populations might emerge from surrounding areas in subsequent years. Without continuous preventative measures, such as maintaining a sealed home exterior and managing host trees, re-infestations are possible, making long-term control a partnership between professional service and homeowner vigilance.

What Preventative Measures Can I Take to Keep Boxelder Bugs Out of My Summerville Home?

To effectively keep boxelder bugs out of your Summerville home, focusing on exclusion is key. Begin by thoroughly inspecting your home's exterior in late summer and early fall, sealing any cracks, crevices, or gaps in the foundation, siding, and around windows and door frames with good-quality caulk. Ensure all window and door screens are in good repair and consider installing mesh screens over vents, including attic, soffit, and dryer vents. Trimming back boxelder or maple trees near your home, especially female seed-bearing trees, can also reduce nearby populations, as these are their primary food and breeding sources.
