Box elder bugs are one of the most recognizable fall invaders in Nebraska — red-and-black insects that swarm on the sides of homes every autumn, clustering in large groups on warm exterior walls before pushing their way inside to overwinter. They’re not dangerous, but they’re a nuisance in numbers, and they can stain fabrics and surfaces with their reddish feces. If they’re showing up on your Springfield property every fall, there’s a reason — and a solution.

Signs of a Box Elder Bug Problem

  • Large clusters on exterior walls in fall — red-and-black bugs, about ½ inch long, gathering in sunny spots on the sides of homes and fences in September and October
  • Bugs indoors at windows and warm surfaces — if they’ve gotten inside, you’ll find them near windows, around baseboards, and in other warm spots
  • Reddish staining on curtains or walls — their excrement leaves reddish-brown stains on light fabrics and painted surfaces
  • Mild odor when crushed — like many true bugs, they emit a faint unpleasant smell when smashed
  • Spring reappearance — overwintering bugs emerge in March and April as temperatures warm, sometimes surfacing in living spaces

Why Box Elder Bugs Are Common in Springfield

Box elder bugs feed on the seeds of box elder trees — and box elder (Acer negundo) is one of the most common volunteer trees in Nebraska. It grows along fence lines, creek banks, alleys, and property edges throughout the Omaha metro and surrounding communities. Wherever box elder trees grow, box elder bugs follow.

Springfield has the tree coverage, the seasonal temperature swings, and the residential building stock that makes it perfect box elder bug territory. These insects spend the warm months feeding and reproducing on box elder trees. As fall arrives, they move toward warm structures in large aggregations. A home or building on the sunny side of a block with mature trees nearby is particularly attractive to them.

Once inside, they overwinter quietly in wall voids and attics. Spring warming brings them back out — sometimes in large numbers, and sometimes into the wrong rooms.

Our Box Elder Bug Control Process

Exterior barrier treatment in fall is the primary approach. Miller Pest Solutions applies residual insecticide to exterior walls, around windows, door frames, and foundation gaps — the routes box elder bugs use to enter. Treatment is timed to coincide with their fall aggregation, before they’ve entered in large numbers.

We also evaluate the property for exclusion opportunities — gaps around utility penetrations, worn caulking around window frames, attic vents without proper mesh, and door seals that aren’t making good contact. Sealing these points reduces box elder bug pressure year over year.

For existing interior infestations, we can treat void areas accessible from the interior and exterior. If you’re seeing them emerge in spring, addressing the entry points before next fall is the smart move.

Box elder tree removal isn’t something we do, but if you have a box elder tree immediately adjacent to your home and box elder bugs are a persistent problem, it’s worth considering as a long-term landscape solution.
