As the temperatures drop in Des Moines and across Central Iowa, it’s not just leaves falling from the trees—it’s boxelder bugs invading homes and businesses. At Janssen Pest Solutions, we’ve been protecting Iowa families from seasonal pests for over 35 years, and boxelder bugs are among the most common and frustrating fall invaders.

Here’s what you need to know about these nuisance pests—and how our locally owned team can help you get rid of them for good.


What Are Boxelder Bugs?

Boxelder bugs are black insects with reddish-orange markings on their backs. They get their name from their favorite host: the boxelder tree, although they’re also attracted to ash and maple trees. During spring and summer, they live outdoors, feeding on seeds and tree sap. But when fall arrives, these bugs start looking for a warm place to hunker down for winter.

Unfortunately, that place is often your home.

Why Boxelder Bugs Invade Des Moines Homes

As soon as the weather cools in Des Moines, Waukee, Ankeny, and other Central Iowa communities, boxelder bugs begin clustering on the sunny sides of buildings. They squeeze into cracks around windows, doors, siding, and rooflines—eventually slipping into walls, attics, and living spaces.

While boxelder bugs don’t bite, sting, or carry disease, they stain curtains and walls, emit a foul odor when crushed, and can show up in large numbers—making them a major nuisance.


Where You’ll Find Boxelder Bugs

Boxelder bugs are typically spotted:

  • Around south- and west-facing walls
  • Near windows and door frames
  • In attics, basements, and wall voids
  • Inside homes during warm winter days

Once inside, they can reappear during mild spells throughout the winter—often catching homeowners off guard.
