Pest Control in Toronto

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.

Most reputable firms include a retreatment guarantee — commonly 30-90 days for one-off jobs, and continuous coverage on service plans. Get the guarantee in writing, including what voids it (e.g. not following prep instructions, sanitation issues). 'Lifetime' guarantees usually mean an ongoing paid contract, not a one-time promise.

If you have a single, identifiable problem (a wasp nest, one ant trail), a one-off visit is cheaper. If you get recurring seasonal pests, an annual plan with quarterly visits usually costs less than three separate emergency callouts and includes free retreatments between visits. Check the plan's cancellation terms before signing — auto-renewal with exit fees is common.

Clear access to skirting boards, under sinks and behind appliances; store open food and utensils away; note where and when you've seen pests (photos help); secure pets and cover fish tanks. For bed bug jobs, follow the company's prep sheet exactly — bagging laundry and decluttering — or the treatment can fail.

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.
