Elm Seed Bug and Boxelder Bug Control in East Denver

Posted by Mosquito Squad

December 12, 2025

When late summer turns into early fall in East Denver, the cooling temperatures may signal the end of mosquito season… but they also signal the beginning of a new era of pests. Elm seed bugs and boxelder bugs are both known throughout the state for seeking warmth as the weather shifts, and unfortunately, homes like yours are prime spots.

 

If you’ve noticed these insects gathering around doors, windows, or siding, now is the time to act. Mosquito Squad offers effective elm seed bug control in Denver and boxelder bug control in East Denver that can help keep your home feeling cozy all fall and winter long.

The Problem With Elm Seed Bugs and Boxelder Bugs

Both elm seed bugs and boxelder bugs are opportunistic pests that spend most of their time looking for the comforts of stable conditions, plentiful food, and warm sunny areas. On sunny fall days, you may see them gathering on the side of your home or clustering around south- and west-facing windows. While they’re mostly harmless to humans, they can be pretty irritating when they’re indoors.

 

Elm seed bugs, in particular, release a noticeable odor when crushed or disturbed. Boxelder bugs, though less pungent, tend to appear in large numbers and are known to stain surfaces with their excrement. Both types of pests tend to gravitate toward wall voids, attics, and other hidden spaces, and will throughout the winter whenever indoor heat entices them out.

What makes them especially frustrating is how persistent they can be. Once they’ve chosen your home for winter shelter, they’ll return year after year unless you take action.

How These Pests Get Inside

Both elm seed bugs and boxelder bugs are pros when it comes to breaking and entering. Some of their most common entry points include:

  • Cracks in siding and foundations
  • Gaps around windows and doors
  • Unscreened attic vents or chimneys
  • Openings around utility lines or exhaust vents

 

Because they move in groups and multiply quickly, it’s not uncommon for homeowners to discover dozens — or even hundreds — inside within a few days.
