About our service
Pest control for Ontario, OR
Ontario sits in one of the driest, hottest parts of the state we cover, and that changes how pest problems show up. With a population near 12,000, the city has ball fields, parks and campuses to go with its homes and businesses: Lions Park, Laxson Park, Moore Park, Eastside Park, Treasure Valley Community College and Eastern Oregon University's Ontario location, among others.
Natural Pest Solutions provides ant treatment, rodent control, spider control, mosquito control and pest inspections for Ontario residents and businesses. We offer natural pest control options with non-toxic, low-impact products that are safe around kids and pets. You will not be asked to sign a long-term contract, and a free quote comes first so you can see the plan before any work starts.

Know your pests
Pests we treat around Ontario
Pests in Ontario
What we deal with most around Ontario, OR
Hot, dry summers push insects toward anything with water, shade and food, and that usually means your yard, your kitchen and your irrigation lines. Ants are a constant, especially where sprinklers keep soil damp. Wasps look for sheltered spots under eaves and in sheds, spiders follow whatever insects gather near porch lights, and mosquitoes breed wherever irrigation water sits still for a few days.
Cool months bring a different problem. Ontario has about 150 nights a year at or below freezing, so mice and other rodents are looking for warm, quiet shelter for a long stretch. Boxelder bugs can gather on sunny walls when the weather turns, and cockroaches stay comfortable indoors year round. Sealing gaps in the fall does more than any product applied after the fact.
Weather and pests
How Ontario's weather affects pest activity
The figures here are 1991-2020 NOAA climate normals from a nearby weather station, so treat them as a guide, not a forecast. Ontario gets only about 10 inches of precipitation in a typical year, and winters bring some snow (about 15 inches). July highs average about 93 degrees, and roughly 62 days a year reach 90 degrees or higher. Winters are cold, with January lows around 23 degrees and December the coldest month. December is also the wettest month, at just 1.6 inches.
In a place this dry, water is the magnet. Lawns, drip lines, leaky spigots and pet bowls all draw pests, and a small damp patch beside the foundation can support ants and termites for a long time. Long stretches of heat also speed up insect life cycles, so populations can jump quickly in midsummer. In the evening, standing water in planters, buckets and clogged gutters is enough for mosquito control to become a real need.
For Ontario homes we suggest a rhythm built around the extremes. Treat the exterior in late spring before the heat arrives, fix irrigation leaks and drain standing water through summer, and close up cracks, garage gaps and vent screens by early fall. Once the long freezing season starts, a quick check of attics, sheds and crawl spaces for rodent activity can save you from a bigger repair later.
How we fix it
Pest control services in Ontario
Ant treatment in Ontario
Ants are among the most common calls we get in Ontario, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Hot summers keep colonies growing all season. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in Ontario
Mice and rats look for food, warmth and shelter, and Ontario buildings offer plenty of all three. With a long cold season, the pressure builds every fall. 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 Ontario
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 Ontario home is built.
Cockroach control in Ontario
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 Ontario apartments, restaurants and older homes alike.
Spider control in Ontario
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 Ontario
A little standing water is all it takes for mosquitoes to breed in Ontario. 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.
