About our service
Pest control for Mercer Island, WA
Mercer Island is a city of about 25,300 people, and it is defined by water on every side. Public spots such as Groveland Park, Miller Landing, Forest Landing, Franklin Landing, Hollerbach Park, Mercerdale Park and Island Crest Park make it easy to get outdoors, and they also put trees, shade and moisture near many homes. Pests take advantage of exactly that combination, so a pest problem here is rarely just about the house.
Natural Pest Solutions provides ant treatment, rodent control, termite control and pest inspection service on Mercer Island. We offer natural pest control options, using non-toxic, low-impact products that are safe around kids and pets. There is no long-term contract, and you can request a free quote before deciding on anything.

Pests in Mercer Island
What we deal with most around Mercer Island, WA
The pests we hear about most on Mercer Island are carpenter ants in damp wood, termites near soil and foundations, mice and rats in attics and walls, and spiders around windows and outdoor lights. Mosquitoes use gutters and shaded planters, and wasps build nests in eaves and hedges by late summer. Homes with mature trees and dense landscaping give all of these pests more cover and more ways to reach the house.
Mercer Island has about 30 nights a year at or below freezing and only about 3 days a year at 90 degrees or higher, so weather here is on the gentle side. That is a mixed blessing. Insects and rodents rarely face a hard reset, which lets ant colonies and mouse populations carry on close to homes for much of the year.
Weather and pests
How Mercer Island's weather affects pest activity
Mercer Island receives about 36 inches of precipitation in a typical year and essentially no snow. July highs average about 77 degrees, and August is typically the warmest month. January lows average around 37, and December is usually the coldest. November is the wettest month, averaging about 5.8 inches. These figures are 1991-2020 NOAA climate normals from a nearby weather station, so they are a guide, not a forecast.
The mild temperatures and wet fall mean wood and soil stay damp long enough to attract carpenter ants and termites, particularly on shaded sides of a house, around decks and near irrigation. Since hard freezes are uncommon, ants may start foraging again on the first warm days of late winter, and spiders and other insects remain active longer into the year than many people expect.
A year-round routine works well here. In late winter, look for early ant trails and moisture damage. In spring, cut back plants touching siding. Through summer, keep water from pooling and watch for wasp nests. In fall, clear gutters and seal gaps around pipes, vents and garage doors before rodents come looking for a warm spot.
How we fix it
Pest control services in Mercer Island
Ant treatment in Mercer Island
Ants are among the most common calls we get in Mercer Island, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Activity climbs quickly once spring temperatures arrive. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in Mercer Island
Mice and rats look for food, warmth and shelter, and Mercer Island buildings offer plenty of all three. They can be a year-round issue. Our exclusion-based approach combines inspection, sealing entry points, trapping and monitoring, so you fix the reason rodents got in, not only the rodents you can see.
Termite control in Mercer Island
Termites are a quiet threat because damage often goes unnoticed for years. A yearly inspection costs little next to the cost of repairs. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your Mercer Island home is built.
Cockroach control in Mercer Island
Cockroaches are hard to get rid of with store-bought sprays. We locate the hiding places, treat cracks, crevices and voids, and use monitoring so we know the treatment worked. It is a common request in Mercer Island apartments, restaurants and older homes alike.
Spider control in Mercer Island
Most spiders are harmless, but nobody wants webs around the door or a spider in the basement. We remove webs and egg sacs, treat the perimeter and reduce the insects that spiders feed on, which keeps them from coming back.
Mosquito control in Mercer Island
A little standing water is all it takes for mosquitoes to breed in Mercer Island. We treat resting areas in your yard, help you find and remove breeding sites and schedule visits through the warm season so you can use your yard again.
