Boxelder Beetles Invade Homes as Temperatures Drop

Ways To Subscribe

Good morning!

I’m Lacy McKay.

Here’s the KSJD outdoor report

You’ve probably seen them — those black bugs with bright red stripes crawling on windows or ceilings or really anywhere with light. They're called boxelder beetles, and while they’re mostly harmless, they can definitely be a nuisance. These insects are attracted to the warmth of buildings as the weather cools, often clustering on the sunny sides of homes and sneaking in through tiny gaps to overwinter indoors. Once inside, they won’t reproduce or do any damage, but they can stain surfaces and — yes — occasionally end up in your hair or clothes.

To keep them out, start by sealing up cracks around windows, doors, and siding. Repair torn screens, and check that your attic and basement vents are tightly fitted. Vacuum up any beetles that make it inside — don’t squish them, as they can leave a smelly stain. Outdoors, try removing nearby female boxelder trees if the problem is severe, since these bugs rely on them for food. And remember — while they may be annoying, boxelder beetles don’t bite, sting, or cause structural harm.

That’s the KSJD Outdoor Report for today.

Stay safe out there.
