One side of the house looks perfectly normal. The sunny side apparently has a guest list.
If you’ve noticed clusters of black-and-red bugs on your siding, you’re seeing a familiar fall habit of box elder bugs. Around Bloomington, sun-warmed walls give them a place to gather as temperatures cool, especially on the south and west sides of homes.
The part worth getting ahead of? Small gaps around windows, doors, and siding can let them move from sunbathing outside to sheltering inside.
Take a look around the areas where they’re gathering. Worn weatherstripping, torn screens, and openings around utility lines are good places to start.
At Scott’s Termite & Pest Control, our box elder bug control in Bloomington addresses exterior gathering spots and the entry points that can lead to repeat indoor sightings.
Seeing more bugs on the siding than you’d like? Reach out today, and let’s work on keeping that fall gathering outside.
