Pest Control near you in Canada

It depends on the pest. Wasp nests and one-off ant trails are usually solved in a single visit. Cockroaches, bed bugs, fleas and rodents almost always need 2-3 visits, because eggs laid before the first treatment hatch after it. Ask upfront whether follow-up visits are included in the quoted price.

Bait and traps knock down the current population, but permanence comes from exclusion: sealing gaps bigger than a pencil around pipes, vents, doors and rooflines, plus removing food sources. Good rodent jobs are quoted as a program — initial treatment, follow-up checks, and proofing — not a single bait drop.

Exterior barrier sprays typically remain effective 60-90 days, less in heavy rain. Gel baits keep working for weeks as insects share them. Rodent programs are about proofing, not just bait, so results last as long as entry points stay sealed. This decay is why prevention plans run quarterly.

That's usually the flush-out effect: insecticides drive insects out of harborage areas, so activity spikes for 1-2 weeks before dropping sharply. If you're still seeing live pests after 2-3 weeks, call the company back — most guarantee retreatment within 30-90 days.

For prevention, quarterly service is the industry standard — barrier treatments wear off after 60-90 days. Active infestations (roaches, mice, bed bugs) usually need visits every 2-4 weeks until cleared. Food businesses and homes backing onto woodland or water often move to monthly service.

Expect roughly $400-$1,000 per room for insecticide programs over 2-3 visits, or $1,200-$3,000+ for whole-home heat treatment. Toronto and other large rental markets have heavy bed bug pressure, so multi-unit coordination through your landlord is often required.

Cold knocks down exterior insect activity, but it pushes mice, rats and squirrels indoors — rodent calls peak in fall and winter. Overwintering insects like cluster flies and boxelder bugs also move into wall voids in autumn, so exclusion work is best done in late summer.
