Pests in Lake Oswego
What we deal with most around Lake Oswego, OR
Mature landscaping brings lovely shade, and it also gives carpenter ants a steady supply of damp wood. Stumps, fallen limbs, wood mulch and fence posts can all shelter colonies, and once they move toward the house they can excavate window frames, decks and roof edges. Termites work more quietly, feeding on framing that stays in contact with moist soil.
Rodents and squirrels look for warm attics and crawl spaces once the weather cools, and they can gnaw through insulation and wiring. Spiders and wasps colonize eaves, outdoor lights and garden structures, and mosquitoes breed in pooled water, including water in planters, gutters and unused containers. Homes near wooded areas also see ticks, and stink bugs gather on sunny siding before moving inside in the fall.
Weather and pests
How Lake Oswego's weather affects pest activity
Lake Oswego has a mild, wet climate. According to 1991-2020 NOAA climate normals from a nearby weather station, which are a guide and not a forecast, July highs average about 84 degrees and August is the warmest month. Around 20 days a year reach 90 degrees or higher, so summers are pleasant but can get warm.
December is the coldest and wettest month, at about 7 inches of precipitation, and January lows average near 37 degrees. Around 30 nights a year fall to freezing or below, and snow is essentially absent. Annual precipitation is about 45 inches, which is a substantial amount of rain and keeps soil, mulch and wood damp through much of the year. That steady moisture is why carpenter ants, termites and mosquitoes are such regular visitors.
The best approach is to control moisture and access. Keep mulch a few inches away from siding, direct downspouts away from the foundation, and trim branches so they do not touch the roof. Do a spring check for damp wood, a summer check for standing water and nests, and a fall check for gaps around pipes, vents and garage doors before rodents move in for the season.
How we fix it
Pest control services in Lake Oswego
Ant treatment in Lake Oswego
Ants are among the most common calls we get in Lake Oswego, 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 Lake Oswego
Mice and rats look for food, warmth and shelter, and Lake Oswego 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 Lake Oswego
Termites are a quiet threat because damage often goes unnoticed for years. Regular moisture around foundations makes regular checks especially worthwhile. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your Lake Oswego home is built.
Cockroach control in Lake Oswego
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 Lake Oswego apartments, restaurants and older homes alike.
Spider control in Lake Oswego
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 Lake Oswego
Lake Oswego's wet weather makes mosquitoes a real nuisance. 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.
