Oshawa’s got character. It’s Durham’s biggest city — 175,000 people, a lot of automotive history, and neighborhoods that range from Lake Ontario waterfront homes to brand-new subdivisions pushing north toward the farmland. That mix of old and new means pest problems show up in different ways depending on where you live. Carpenter ants love the newer builds. Silverfish and moisture pests creep into waterfront basements. And every fall, like clockwork, mice start looking for warm garage spaces and basement corners.
We’re CallPest. We dispatch licensed exterminators across Oshawa, Whitby, Courtice, and the rest of Durham Region. Same-day service. No runaround. You call, we show up, we fix it.
Pest Problems in Oshawa — What We See Most
Carpenter ants in the north subdivisions. If your house was built in the last 10 years anywhere north of Taunton Road, you’ve probably seen them. Big black ants, wings in the spring, sawdust trails near window frames. They show up April through June when the weather warms up, and they’re not just annoying — they’re chewing through structural wood. The newer the neighborhood, the more exposed lumber there is during construction, and that’s where infestations start.
Silverfish and moisture pests near the lake. Oshawa’s waterfront is beautiful, but Lake Ontario brings humidity. Older homes near Lakeview Park or along the waterfront trail deal with silverfish in bathrooms, basements, and laundry rooms. You’ll see them darting across tile floors at night. They don’t bite, but they eat paper, fabric, and anything with starch in it — which means books, clothing, and wallpaper are all fair game.
Mice and rats every fall. September hits, temperatures drop, and rodents start moving indoors. Garages attached to houses are the easiest entry point. They chew through weatherstripping, squeeze under garage doors, and set up nests in insulation or storage boxes. By the time you hear scratching in the walls at night, they’ve been there for weeks.
Wasps in the summer. Wasps build nests under eaves, in soffits, and inside sheds. June and July are when we get the most calls — someone’s mowing the lawn, gets too close to a ground nest, and suddenly there’s a problem. Don’t try to knock it down yourself. One nest can hold hundreds of wasps, and they will defend it.
Bed bugs year-round. Oshawa’s got apartment buildings, rooming houses, and a lot of turnover in rental properties. Bed bugs don’t care how clean your place is — they hitch rides on luggage, furniture, and clothing. If you’re waking up with bites in clusters or finding dark spots on your mattress seams, call us today. Bed bugs spread fast, and DIY treatments don’t work.

FAQ — Pest Control in Oshawa
How much does pest control cost in Oshawa?
Depends on the pest and the size of the job. Mouse trapping and exclusion typically runs $300-600. Bed bug heat treatment is $500-1,200 depending on how many rooms. Wasp nest removal is usually $150-300. We give you a firm quote before we start — no surprises.
Do you offer same-day service in Oshawa?
Yes. Most calls get same-day service if you call before early afternoon. Emergency jobs — like wasps in a kid’s bedroom or a raccoon in the attic — we prioritize and often arrive within a couple hours.
Are your treatments safe for pets and kids?
Yes. We use eco-friendly products wherever possible, and we’ll walk you through any precautions (like keeping pets out of a room for a few hours). Most treatments are safe for re-entry within 2-4 hours.
What’s the best time of year to prevent carpenter ants in Oshawa?
April and May, right before they start swarming. If you live in one of the newer subdivisions north of Taunton, consider a preventative perimeter treatment in early spring. Once they’re inside the walls, treatment gets more complicated.
Do I need to leave my house during pest treatment?
Not usually. For most jobs — mice, ants, cockroaches — you can stay home. For bed bug heat treatment, you’ll need to be out for 4-6 hours while we bring the room temperature up to 130°F. We’ll let you know ahead of time.
