The New Pesky Pest: Elm Seed Bug

The elm seed bug has come to stay for the summer. Native to Europe, this pest didn’t live in Utah 10 years ago. Over time it has become more and more common along the Wasatch Front and in Cache County. The insect gets its name from where it’s found and what it eats: seeds from elm trees.

Identifying the Elm Seed Bug

Easily confused with the boxelder bug because of its brown and black colors, the elm seed bug doesn’t harm elm trees or humans. It’s a nuisance, though, because of the odor it lets off. When the bug is squashed or killed, it gives off a bitter almond smell.

While boxelder bugs are usually black with more reddish accents, elm seed bugs tend to be brown with dark orange dots on the edges and an x-shaped mark on the back.

Getting Rid of the Elm Seed Bug

They invade homes from late May to September and are hard to get rid of. A few things homeowners can do to prevent elm seed bugs from invading are as follows:

  • Use pest sprays to keep the bugs away. Stewart’s pest service technicians can spray for elm seed bugs.
  • Make sure your windows have tight window screens and check for cracks in the caulking around the window frame. If your window frame is cracked, seal it up to help keep the bugs out.
  • Check door frames for gaps or cracks, and make repairs as necessary. Doors with tight sweeps will stop elm seed bugs (and other nuisance pests) from entering the house.

Stewarts has a bug barrier program that is perfect for solving your pest problem. If you’re seeing elm seed bugs or any other insect around your home, call or text 801-226-2261 today for a free estimate.
