How to Keep Boxelder Bugs Out of Your Snohomish Home This Fall
Late September in Snohomish county means boxelder bugs are on the move. Although they have a scientific name, Boisea Trivittata, they often go by the name boxelder bugs due to their tendency to gather and feed on boxelder trees. They are a part of the “true bug” family, or the Hemiptera, and have a ½ inch black body with reddish-orange markings along the body and wings.
Boxelder bugs tend to feed primarily on boxelder trees, which is where they get their name. They also feed on both maple and ash trees, sucking the sap from leaves, flowers, and seed pods. Though they rarely cause tree damage, large populations of boxelder bugs can put stress on young trees. This time of year they are typically trying to seek warmth in your home, often in garages, attics, and wall voids.
Are They Dangerous?
The good news about boxelder bugs is that they are not a danger to you. They don’t bite, sting, or damage structures, but they do tend to gather on, and inside homes as the weather gets colder. Whether you live in Edmonds, Mukilteo, or Shoreline, homeowners know how irritating it is to have them swarming walls and sneaking inside during fall. When they are crushed or squished they release an unpleasant smell similar to stink bugs (halyomorpha halys) which they are often confused with, and leave a reddish stain on walls and furniture. While they are not a danger, they are very annoying and irritating. If you find yourself swatting them away this season, give us a call and we would be happy to take care of them for you.

Boxelder Prevention Tips:
- Seal entry points: use caulk to seal cracks around windows, doors and siding.
- Repair screens: ensure that window and door screens are intact and there are no openings.
- Close gaps: check around rooflines and utility pipes for places they could get into your home.
- Yard maintenance: rake seed pods from trees (specifically boxelder trees) and trim back shrubs touching your house. This is especially helpful in tree-filled areas like Gold Bar, Granite Falls, and Sultan, where boxelder trees are common.
Final Thoughts
There are some non-chemical treatments like vacuuming the bugs or spraying them with a soapy water solution. However, these methods will only kill the bugs already inside. Prevention treatments are recommended because the other home remedies or treatments can leave residues in your home, something that could build up over time.
