How to hire a pest control pro in Canada

  1. Verify the provincial pesticide applicator/exterminator licence (e.g. Ontario's Ministry of the Environment exterminator licence, BC's Integrated Pest Management licence)
  2. Ask for proof of liability insurance and WSIB/WCB coverage where applicable
  3. Get the pest identified and a written multi-visit plan for roaches, mice or bed bugs
  4. Confirm the retreatment guarantee period in writing
  5. Ask which PMRA-registered products will be used
  6. For condos and apartments, coordinate with property management — adjoining units often must be treated together

Pest control products in Canada must be registered federally with Health Canada's PMRA, while applicator licensing is provincial — Ontario, BC, Alberta and Quebec each run their own exterminator/applicator certification schemes. Check your province's public registry before hiring.

Frequently asked questions

What should I do before the exterminator arrives?

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.

How do I tell termites from flying ants?

Termites have straight antennae, a thick uniform waist, and two pairs of wings of equal length; ants have elbowed antennae, pinched waists and unequal wings. Mud tubes on foundations, hollow-sounding timber and piles of shed wings near windows point to termites — get a professional inspection quickly, since termite damage compounds.

Can I do pest control myself instead of hiring a pro?

DIY sprays and baits handle light ant or roach activity fine. Hire a professional for anything structural or persistent: termites, bed bugs, rodents inside walls, wasp nests in cavities, or repeat infestations. Pros have access to products and application methods retail products don't match, and misapplied DIY sprays can scatter colonies and make infestations harder to treat.

Do pest control companies guarantee their work?

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.

Who pays for pest control in a rental — landlord or tenant?

It varies by lease and jurisdiction, but the common pattern is: landlords are responsible for infestations arising from the building (rats, structural entry, problems present at move-in), while tenants pay when the infestation results from their own housekeeping or was introduced by them (e.g. fleas from pets). In multi-unit buildings, roach and bed bug treatment usually needs adjoining units treated at the same time — coordinate through the landlord or manager.

How much does bed bug treatment cost in Canada?

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.

Do Canadian winters kill off pests?

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.
