Earwigs are a moisture pest, and Star hands them two water sources at once: the Boise River along the edge of town and the fresh, heavily watered landscaping on its fast-growing new lots. This page covers why Star homes get earwigs, how we keep them out, and what you can do yourself. Rather just talk it through? Call (208) 949-5184.
Why Star gets earwigs
Star went from a small farm town to one of the fastest-growing places in Idaho, and most of that growth is new homes built on what was pasture and horse property a few years ago. Those new lots come with fresh sod, drip-fed beds, and a bark mulch collar against the foundation, all of which hold moisture right where earwigs want it. When ground is graded from pasture into a subdivision, the insects living in the old field move into the new landscaping, and earwigs are among the first to settle into the damp mulch against a new house.
The Boise River is the other half of the story. The river corridor runs along the south side of Star, keeping the ground and air damp and growing a heavy insect population in the cottonwoods and bank vegetation. Homes in newer subdivisions near the river, and on former pasture ground elsewhere in town, sit close to that moisture. This is high desert, so the river and the irrigation are doing all the work of keeping things wet, and earwigs concentrate wherever that water collects, especially the mulched beds nearest the foundation. Moisture drives their whole life, as our earwigs in Idaho guide explains.
How we treat earwigs in Star
With earwigs the habitat carries most of the load, so on a Star visit we start at the wet ground. We walk the foundation and point out the fresh sod, wet mulch, and low spots holding moisture against the house, then treat the damp bands where earwigs hide and travel along the slab. We put a Bifen barrier around the base of the house, applied according to its label with kids and pets in mind. The full method and the non-repellent products labeled for earwigs are on our earwig control service page. Because the river-bottom damp and unused new-build floor drains also bring Oriental cockroaches up from below, our cockroach control in Star uses the same moisture work.

Earwig numbers peak in the hot midsummer weeks. Through July and August the surface of the beds and the river-bottom ground dries during the day while the population tops out, so the earwigs crowd toward the cool, damp soil against the foundation and move indoors after dark. Homes closest to the river and on freshly landscaped lots tend to feel it first. A barrier set before that peak keeps them out of the bath and kitchen. Our Treasure Valley pest calendar shows how the earwig peak fits the rest of the year.
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 a Star 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 so the wet layer is not touching the house.
- Water the new sod and beds deeply in the morning. Long, infrequent morning watering lets the surface dry by nightfall instead of staying damp when earwigs feed.
- Fix the low spots the new lot left behind. Fresh grading often leaves dips that pond and stay soggy. Regrade so the ground next to the house drains and dries.
- Seal the low gaps and add a tight door sweep. On a new build, the door sweeps and utility penetrations are the routes earwigs use on a hot night. Close them.
When to call
If you have dried the perimeter and still find earwigs indoors, the population around your home is big enough that a perimeter treatment will earn its keep. A new Star lot rarely has just one pest moving in, and the same recurring visit covers the rest, which is what our broader Star pest control is built for. Every plan carries the Pynk Guarantee: if earwigs come back between visits, so do we. Request a free Star quote whenever you are ready.
Common questions
Are earwigs dangerous to have around the kids?
No. Earwigs are harmless to children. The pincers look alarming, but they hold no venom, they cannot break skin, and the most a large one can manage is a faint pinch if a curious kid picks it up. They do not bite, they do not sting, and they are not looking for people. If your child finds one in the bath, it is a startle, not a hazard. The forceps are for other earwigs, not for us.
We are near the Boise River in Star. Is that why we have earwigs?
It is a big factor. The river corridor keeps the ground and air damp along that side of Star, which suits earwigs perfectly, and the cottonwoods and vegetation along the bank feed a large population that spreads into the nearest yards. You cannot dry out the river, but you can keep your own foundation dry and defended, so the earwigs moving off the river bottom do not find easy harborage the moment they reach your house.
Our Star subdivision was pasture a couple years ago. Does that matter for earwigs?
It does. When pasture and farm ground is graded into a subdivision, the fresh sod, new beds, and bark mulch that replace it hold moisture against brand-new foundations, and the displaced insects from the old ground move into the new landscaping. Newer Star neighborhoods often see earwigs build over their first summers. Pulling the mulch off the slab and drying the perimeter gets ahead of it.
Are earwigs a sign of a bigger problem in my new Star home?
Usually not. Earwigs indoors almost always mean damp harborage right outside, not structural trouble or an infestation breeding in the walls. They are outdoor insects wandering in from the wet mulch and river-bottom ground, so a cluster in the tub points to moisture at the foundation, which is fixable. The one exception worth checking is a plumbing leak or a chronically wet crawl space, since those can hold earwigs and other damp-loving pests inside.
Do earwigs come indoors in winter, or just summer?
Almost entirely summer. Earwigs overwinter outdoors in the soil, where the females guard their eggs, so you rarely see them inside in the cold months. The indoor problem is a midsummer one, driven by the July and August heat pushing the peak population off the drying ground and toward the damp foundation. If you are finding live earwigs indoors in winter, it usually means a warm, damp spot inside, like a leak or a wet crawl space, is holding them.
