Boxelder bugs: harmless… but definitely not welcome.
These black-and-red pests love trees like maple and ash but when temps drop, they start looking for a warm place to crash… aka your house.
They don’t bite or damage your home but they will:
- Gather in huge numbers around windows & siding
- Sneak in through tiny cracks
- Leave stains and odors if crushed
Why are they all over your house?
- They’re drawn to sunny walls (especially south & west facing)
- Fall weather triggers them to move indoors to overwinter
Want fewer of them?
- Seal up cracks & gaps
- Keep leaf litter and debris away from your home
- Treat around windows, doors, and siding
They may not be dangerous but when they show up by the hundreds, it’s a problem.
