Same-day pest removal in Oshawa. Licensed, insured, and guaranteed.
Get a Free QuoteOshawa is Durham’s biggest city, and it has the pest problems that come with a big, mixed housing stock — older homes downtown, a large rental and student market near the universities, and new subdivisions pushing north. If something’s moved into your place, we can be there fast.
We’re CallPest. We dispatch licensed exterminators across Oshawa the same day you call — downtown, Lakeview, Donevan, Vanier, McLaughlin, and the newer Windfields area up by Ontario Tech and Durham College. No runaround, no next-week booking, no surprise fees.
Oshawa’s combination of aging houses and constant rental turnover is exactly what pests like bed bugs, cockroaches, and mice thrive on. We know the patterns here because we treat them every week.
Oshawa’s most common pest problems
Bed bugs in rentals and student housing. Oshawa has a large rental market and thousands of students at Ontario Tech and Durham College. High turnover, shared houses, and secondhand furniture make bed bugs one of our most frequent Oshawa calls. It has nothing to do with cleanliness — it’s about exposure. Heat treatment clears a room in one visit.
Cockroaches in older multi-unit housing. Downtown Oshawa and the older apartment stock along King and Simcoe have long-standing German cockroach populations. They spread between units through shared walls and plumbing. Treating one unit while the neighbours are infested just moves the problem around — we handle it properly.
Mice in older homes and new north-end builds alike. The older neighbourhoods (Vanier, Donevan, central Oshawa) have decades of foundation settling and worn weatherstripping. The new Windfields subdivisions sit on former farmland. Both get mice every fall — just for different reasons. We seal the way in either way.
Carpenter ants near Oshawa Creek. Homes along the Oshawa Creek valley and the older tree-lined streets see carpenter ants in spring and summer, nesting in damp or damaged wood. Left alone, they can do real structural harm.

Why Oshawa chooses CallPest
Plenty of Toronto-based companies quietly deprioritize Durham — they’ll take the booking but you’re at the back of the line. We keep technicians in Durham Region every day, so Oshawa gets the same same-day urgency as anywhere in the GTA.
We also work with landlords and property managers, which matters in a city with this much rental housing. For recurring problems in multi-unit buildings, we’ll build a plan that actually addresses the source instead of chasing it unit by unit.

Questions about pest control in Oshawa
Do you offer same-day pest control in Oshawa?
Yes. Oshawa is one of our busiest Durham Region areas and we keep technicians nearby. Call before noon and we can usually be there the same afternoon.
Do you treat student rentals and apartments in Oshawa?
Yes — we work with students, tenants, landlords, and property managers near Ontario Tech, Durham College, and across the city. For bed bugs and cockroaches in shared or multi-unit housing, coordinating treatment across affected units is the only reliable fix, and we can help arrange it.
How much does pest control cost in Oshawa?
Typical ranges: bed bug heat treatment $300-800 per room, cockroaches $200-500, mice $250-600, ants $200-400. We quote everything before we start — no hidden fees, no trip charge.
Why does Oshawa have so many bed bug calls?
It comes down to a large rental market, a big student population, and lots of moving in and out. Bed bugs travel on furniture, luggage, and clothing, so high-turnover housing spreads them fast. Again — it is not about how clean a home is.
Are your technicians licensed in Ontario?
Yes. Every technician holds a valid Ontario Exterminator Licence under the Pesticides Act and carries full liability insurance. We use only Health Canada-registered products.
