Box Elder Bugs in Southeast Idaho
How and Why Box Elder Bugs Get Inside
In Rexburg and across Southeast Idaho, box elder bugs are a normal part of the landscape. They feed and breed on box elder, maple, and similar trees through the warm months, then gather in large numbers on sunny siding, brick, and south- or west-facing walls as the weather cools.
When temperatures drop, they look for sheltered spots to ride out the cold. They slip into cracks around siding, vents, windows, doors, and rooflines, tucking themselves into wall voids and other protected spaces. On warm or sunny days, they follow the heat and light and end up on interior walls and windowsills, which is why it can feel like they keep coming back even after you've vacuumed and sprayed the ones you can see.
Do I Have a Box Elder Bug Problem?
Common Signs of a Box Elder Bug Infestation
Seeing a few box elder bugs outside isn't unusual, but certain patterns can point to a real problem. Watch for:
- Large clusters of bugs on sunny exterior walls, especially on the same side of the home every year.
- Bugs gathered around doors, windows, or garage doors where people come and go.
- Box elder bugs appearing indoors on warm or sunny days, especially near windows or in upper stories.
- Repeated fall and spring activity where the same areas of your home are covered in bugs each season.
If this sounds like your home, a targeted treatment can help cut down the numbers dramatically and make your home much more comfortable during box elder season.
