How listings are vetted

  1. 1

    Start from Google Maps

    Every listing begins as a public Google Maps record in the pest control category, anywhere in Ontario.

  2. 2

    Keep the active ones

    Businesses with no reviews, or no update in the past year, are left out. Duplicate records are merged.

  3. 3

    Read their own words

    Each company's website and review topics are read for the pests it treats and the services it offers.

  4. 4

    Mark what is unknown

    When a company says nothing about a service, the listing says "not enough info" instead of guessing.

This directory started from every Google Maps business in Ontario filed under pest control, about 940 records. We dropped businesses that had no reviews or had not been updated in a year, merged duplicate records, and set aside companies whose own websites showed they do other work, such as lawn care, cleaning, roofing or wildlife removal on its own. That left 845 companies.

For each company we read its own website and the topics in its Google reviews, then marked fifteen services as yes, no or not enough info: bed bugs, heat treatment, mice and rats, rodent proofing, cockroaches, ants, wasps, mosquitoes and ticks, wildlife, commercial work, eco-friendly options, same-day service, a treatment guarantee and a stated exterminator licence. A yes means the company says it offers the service. We have not inspected any company or checked any licence, so confirm both before you book.

Owners can claim a listing to correct details or add photos. A person checks every claim. Published by Dennis Bobby.

How to choose a pest control company in Ontario

The work Ontario pest control companies take on most often is a short list: mice and rats, ants, wasp nests, bed bugs and cockroaches, in that order on this directory. Most companies handle several of them, so the useful question is not who does pest control, but who does your pest, at your address, the way you need it done.

Start with the pest

Each listing shows a service grid. A tick means the company says it treats that pest or offers that service; a cross means it says it does not; "not enough info" means it says nothing either way. Bed bugs are the clearest case for reading the grid closely. Of the 531 companies here that treat bed bugs, 134 say they offer heat treatment, which some households prefer to chemical treatment. For mice and rats, look for rodent proofing as well as treatment: a company that seals entry points is working on why the mice got in, not only on the ones already inside.

Check the licence

Ontario requires an exterminator licence from the Ministry of the Environment, Conservation and Parks for anyone who applies pesticides as an exterminator, and a business that does the work for pay needs an operator licence. Technicians may work under a licensed exterminator's supervision. The grid shows whether a company states a licence on its own website; we have not checked any of them. Ask for the licence number on the first call, and ask which products will be used. Every pesticide registered in Canada carries a Pest Control Product (PCP) number on its label.

Renting, or a landlord?

Ontario's maintenance standards require a rental building to be kept reasonably free of rodents, vermin and insects, and openings in the building to be screened or sealed against pests. If you rent, the landlord is usually the one to call first. If you own a building, look for companies marked for commercial work: 583 on this directory take commercial jobs, from restaurants and warehouses to apartment buildings.

Read the rating with the review count

A 5.0 from three reviews tells you much less than a 4.8 from four hundred. The listings on each city page sort companies by rating weighted by how many reviews stand behind it, and every card shows both numbers. Read a handful of recent reviews for the pest you have: a company praised for wasp nests may never have treated a bed bug problem.

What to ask on the first call

Ask what the inspection involves and whether it is free, how many visits the treatment needs, what you need to do before and after each visit, and what the guarantee covers if the pest comes back. 504 companies here say they offer a guarantee, so it is fair to ask for its terms in writing. If you need someone today, filter for same-day or emergency service. If children, pets or a home business make low-toxicity products matter to you, filter for eco-friendly options and ask what those products are.

Frequently asked questions

Do pest control companies in Ontario need a licence?

Yes. Ontario requires an exterminator licence from the Ministry of the Environment, Conservation and Parks for anyone who applies pesticides as an exterminator, unless an exemption applies, and a business that does extermination for pay needs an operator licence. Technicians can work under a licensed exterminator's supervision. Ask for the licence number when you call.

My landlord will not deal with mice or cockroaches. What can I do?

Ontario's maintenance standards require a rental building to be kept reasonably free of rodents, vermin and insects, and the Landlord and Tenant Board says landlords must take steps to control pests such as cockroaches and mice. A tenant whose landlord does not maintain the unit can apply to the Board on Form T6.

Which companies on this directory use heat for bed bugs?

134 companies on this directory say they offer bed bug heat treatment, and 531 treat bed bugs by some method. Type heat in the search box and pick bed bug heat treatment, or open your city page and look for it in each company's service grid.

How do I know a pest control product is approved in Canada?

Every pesticide registered for use in Canada carries a Pest Control Product (PCP) registration number on its label. Ask the company which products it will use and check the label for that number.

Are the ratings on this directory reviews of your own?

No. The rating and review count on each listing are the business's Google rating and review count when the directory was last rebuilt. We do not collect reviews or change them, and a paid placement does not change a company's rating.

Do you charge companies to be listed?

No. A basic listing is free and stays free. Companies can pay for a featured position on a city page, a region or the whole province, or for a premium listing with photos and a followed website link. Paid positions are always marked.

My company is listed with wrong details. How do I fix it?

Claim the listing from its page. A person checks every claim against the business's Google listing, its website domain or a call to its listed number, then updates the details and rebuilds the directory. Claiming is free.
