Earwigs are a moisture pest, and old Boise gives them two things at once: deep, damp garden beds and an old house full of gaps to slip through. This page covers why Boise homes collect earwigs, how we keep them out, and what you can do yourself. Rather just talk it through? Call (208) 949-5184.
Why Boise gets earwigs
Boise is not one pest job, and earwigs prove it. A 1920s North End bungalow and a ranch on the Bench share the one trait earwigs care about most: mature, heavily irrigated landscaping that has been building damp organic soil for decades. Thick mulched beds, old shade trees dropping leaf litter, and watered lawns keep the ground cool and moist right against the foundation, which is exactly the daytime shelter an earwig needs to keep from drying out.
The Boise River and its greenbelt add moisture on the south side, and the foothill drainages feed it down from the north, but the real earwig engine is the irrigated yard itself. This is high desert, and the ground bakes without water. The mulched, watered beds of an established Boise neighborhood are an oasis of damp in dry country, and earwigs pack into them. What turns a yard problem into a house problem is the housing stock. Older Boise homes have settled over decades, opening pencil-width gaps along the foundation and around doors that no longer seal, so on a hot night the earwigs ride straight in. The full story of what makes them a moisture insect is in our earwigs in Idaho guide.
How we treat earwigs in Boise
With earwigs the habitat carries most of the load, so we start at the beds. On a Boise visit we point out the wet mulch, the overwatered plantings, and the leaf litter feeding the population, then treat the damp bands where earwigs hide and travel along the foundation and through the beds. We put a Bifen barrier around the base of the house, the band earwigs cross on their way to the doors and weep holes, applied according to its label with kids and pets in mind. The full method, and the non-repellent products labeled for earwigs, is on our earwig control service page. Because the same damp ground and old plumbing bring Oriental cockroaches up through basement and floor drains, our cockroach control in Boise leans on the same moisture work.

Earwig numbers hit their yearly peak in the hot midsummer weeks. Through the baking days of July and August, the surface of those mulched Boise beds dries out while the population is at its high, so the earwigs crowd toward the cool, damp ground at the base of the house and slip inside after dark. In an old home with settled gaps, that indoor push can feel sudden. A barrier set before the July peak keeps them out of the bathroom and basement. Our Treasure Valley pest calendar shows when the push tends to land.
What you can do yourself
Earwigs are one of the most DIY-friendly pests there is, because they live or die on moisture. A few changes around an older Boise home do most of the work.
- Pull the mulch back off the foundation. Keep it to a couple of inches and leave a strip of bare, dry soil between the beds and the wall. A thick, wet mulch layer against an old foundation is prime harborage.
- Seal the settled gaps and fit fresh door sweeps. Old Boise homes leak at the low cracks and worn thresholds. Closing those shuts the doors earwigs use on a hot night.
- Water deeply and in the morning. Long, infrequent morning watering lets the surface dry by nightfall instead of staying damp when earwigs feed.
- Clear leaf litter and debris. Under mature Boise trees, piles of leaves, boards, and bricks against the house are daytime hideouts. Move them well back.
When to call
If you have dried the beds, sealed the gaps, and still find earwigs indoors every morning, the population around your home is big enough that a perimeter treatment will earn its keep. Earwigs are rarely the only pest an old Boise home deals with, and the same recurring visit covers the rest, which is what our broader Boise pest control is built for. Every plan carries the Pynk Guarantee: if earwigs come back between visits, so do we. Request a free Boise quote whenever you are ready.
Common questions
Those pincers look nasty. Can an earwig actually hurt me?
Not really. The pincers are a bluff. An earwig has no venom and no sting, and even a large one can only give a faint pinch that will not break the skin, so there is nothing to fear for you, your kids, or your pets. Earwigs use the forceps to fend off rivals and handle food, not to attack people. The reputation is far worse than the insect.
Where are earwigs getting into my older Boise home?
At the low, damp gaps an older house collects. Decades of settling open pencil-width cracks along the foundation, and worn thresholds under exterior doors let earwigs walk straight in on a summer night. Many North End and Bench homes still have original doors and sills that no longer seal tight. Sealing the ground-level gaps and fitting fresh door sweeps closes the routes earwigs actually use.
Should I get rid of the mulch in my Boise garden beds?
You do not have to. Mulch is good for the garden, and earwigs are only a problem when it sits thick and wet right against the house. Keep the mulch to a couple of inches, pull it back a few inches off the foundation, and leave a dry gap of bare soil there. That single change removes most of the harborage while your beds keep the mulch they need.
Do earwigs mean my Boise house is dirty?
No, and this trips a lot of people up. Earwigs are not drawn to garbage or crumbs the way ants and roaches are. They are chasing moisture, full stop. A spotless Boise home with damp, mulched beds against the foundation will collect more earwigs than a cluttered one with a dry perimeter. The fix is about water and harborage, not housekeeping.
Do earwigs come back every summer?
They can, because the conditions that grow them return every year. The mature, irrigated yards of older Boise neighborhoods stay damp all season and produce a fresh crop of earwigs each summer, so a single treatment handles this year but not next. A recurring plan keeps a barrier up through each midsummer peak, and under the Pynk Guarantee, if earwigs come back between visits, so do we.
