Boxelder bugs are one of the more recognizable pests in Thurston County, and they’re especially common in Tumwater and surrounding areas like Olympia and Lacey. With their black bodies and striking red lines, they’re easy to spot, often in large numbers along sunny walls or inside homes during seasonal shifts.
While not as alarming as roaches or termites, a boxelder bug infestation can still be a frustrating pest problem for local homeowners.
Let’s walk through how to tell if boxelder bugs are invading your Tumwater home, and what steps to take with a trusted pest control company if they are.
Key Takeaways
- Large numbers of boxelder bugs often gather on sunny Tumwater homes before trying to enter for winter.
- Reddish stains, foul odors, and buzzing in walls suggest boxelder bugs are hiding somewhere inside your home.
- Simple steps, such as sealing cracks, vacuuming for bugs, and trimming boxelder trees, can help prevent future infestations.
- Local homeowners trust PCI Pest Control for year-round pest control services and free consultations across Thurston County.
Lots of Bugs on Sunny Walls?
When the weather starts cooling in Tumwater, especially in fall, boxelder bugs begin to gather in large numbers on the sunniest side of your home.
This behavior is typical across neighborhoods near boxelder trees or wooded areas that back up to the Puget Sound. It’s a strong early indicator that they’re preparing to enter your home to overwinter.
There’s a Persistent, Unpleasant Smell Indoors
Unlike more dangerous stinging insects like yellow jackets or wasps, boxelder bugs aren’t aggressive. Still, when squished, they emit an unpleasant odor that can linger for a long time.
If you’re noticing a funky smell near baseboards or vents, it could be from a hidden cluster or from accidentally crushing a few in your living space.
You Notice Reddish Stains on Walls, Curtains, or Furniture
One of the more frustrating signs of a boxelder bug infestation is the stains they leave behind. Homeowners in Tumwater with light-colored furniture or curtains often notice rusty smears after these bugs crawl across surfaces.
It’s similar to what bed bugs can leave behind, but unique to this particular pest.
Buzzing Sounds in Walls or Attic?
Boxelder bugs can squeeze into tight spaces to escape the cold, and in older homes around Tumwater, that often means attic insulation, wall gaps, or crawlspaces.
If you hear light fluttering, it could be a sign that they’ve settled in. Our exterminators have even found them nesting alongside stink bugs or carpenter ants in those same hidden areas.
You See Them Emerging Indoors as the Weather Changes
When temperatures shift in the spring, any boxelder bugs that overwintered in your home may emerge suddenly.
This can happen even if you haven’t seen them in months. You might spot them near window sills or light fixtures, much like other common bugs.
What to Do if You Suspect a Boxelder Bug Infestation
Do you think you’ve boxelder bugs in your home? Here’s what to do next to stop the infestation and keep them from coming back:
Inspect Your Home’s Exterior
Effective pest management starts with a thorough inspection. Look closely at your home’s siding, vents, window frames, and door seals—especially if you live in the older parts of Tumwater or near natural areas where boxelder trees thrive.
These spots are prime entry points during an infestation.
Seal Potential Entry Points
This is where exclusion becomes key.
Sealing up cracks with weather-resistant caulking and replacing worn weatherstripping helps prevent not only boxelder bugs but also other pests, such as fleas, roaches, and stinging insects, from slipping inside.
Vacuum Indoor Sightings Instead of Crushing
Crushing boxelder bugs can worsen the smell and cause staining.
Vacuuming is a cleaner alternative. Dispose of the vacuum bag immediately to prevent reintroducing them. This approach aligns with the kind of preventative measures we often recommend to keep homes pest-free year-round.
Check the Surrounding Trees, Especially Boxelder and Maples
If you live near boxelder trees or similar species, you may be unintentionally attracting these pests. While we don’t suggest cutting down mature trees without cause, trimming limbs that touch your home and clearing fallen leaves can help reduce the attraction.
This is especially relevant for homes in leafy parts of Tumwater or Olympia.
