Pest Control in Saint John

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.

For standard sprays and gels, you typically only need to stay out of treated rooms for 2-4 hours until surfaces dry. Fogging or flea treatments may require 4-6 hours away. Whole-structure fumigation (rare, mostly for termites or severe bed bugs) means vacating for 1-3 days. Your technician must give you re-entry instructions — ask if they don't.

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.

A typical visit includes an inspection, interior treatment of kitchens/bathrooms/entry points, an exterior perimeter barrier spray, and a written report. It usually covers common crawling insects (ants, roaches, spiders). Rodents, termites, bed bugs, wasps and mosquitoes are almost always quoted separately — confirm what's on the ticket.

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.

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.
