How pest control works, from request to follow-up
Successful pest control always follows the same order: understand the problem, inspect it, agree in writing, treat, then check that it worked. Skipping a step is the most common reason a treatment has to be redone. Here is what each step means in practice for a house in Brossard, an apartment in Longueuil or a business in Saint-Jean-sur-Richelieu.
Ask for the CD5 certificate
In Quebec, anyone who performs or offers to perform pest control work with pesticides must hold a CD5 certificate from the Ministry of the Environment. It is valid for five years. Ask to see it before any work begins.
A written quote
Method, number of visits, price and warranty must be in writing before the work, not after.

The five steps
1You describe the situation
Your town, the pest if you know it, what you are seeing, since when, and whether the home is rented. A photo helps a lot. The request is routed by your town's zone.
2Inspection, remote or on site
A wasp nest clearly visible in a photo can often be assessed remotely. Bed bugs, cockroaches or rodents indoors almost always need an inspection to find the real extent and the entry points.
3A written quote
Method, number of visits, total price, preparation required and warranty. Nothing is committed before you have read that document. Inspection fees are sometimes charged separately and then deducted from the treatment: see the pricing page.
4The treatment
Depending on the case: residual treatment, heat treatment, baiting, trapping or exclusion. The technician explains what was applied, where, and how long to wait before using treated rooms again.
5The follow-up
Bed bugs and cockroaches usually need two or three spaced visits to break the egg cycle. For rodents, the follow-up checks that sealed entry points are holding. What the warranty covers is written in advance, not negotiated afterwards.
What is different on the South Shore
Apartment buildings. In the multiplexes and towers of Longueuil or Brossard, treating a single unit often fails: insects travel through shared walls and ducts. The quote must say which neighbouring units will be inspected, and who notifies the tenants.
The farmland ring. In the Saint-Luc and L'Acadie sectors of Saint-Jean-sur-Richelieu, in Sainte-Julie or in Varennes, mice and Asian lady beetles come in from the fields after harvest. Treating indoors without sealing entry points only solves the current season; sealing is part of the method.
Distances. The territory runs from Châteauguay to Granby. That is why each request is tied to a specific zone: no exterminator reasonably covers this whole territory from a single base.
Preparing for the visit
For bed bugs, do not throw out furniture before the inspection: a mattress dragged into the hallway infests others. Wash bedding on the hottest setting and keep it in sealed bags. For cockroaches, clear out under the sink and the kitchen cabinets. For rodents, note where the droppings are: they are the best clue to the runways. The frequently asked questions cover safety for children and pets.
Frequently asked questions
Is an on-site visit always necessary?
Not always for a first estimate. An indoor infestation generally needs an inspection before a firm price can be given, because the real extent is rarely what you can see.
Can the price change after the inspection?
Yes, up or down, if the real situation differs from what was described. That is the point of the inspection: to replace an estimate with a firm price, before treatment rather than after.
What must a written quote include?
The planned method, the number of visits, the total price, the preparation required, the re-entry time and what the warranty covers, for how long. A quote missing any of these is incomplete.
How can I check the technician is qualified?
Ask to see their CD5 certificate, issued by Quebec's Ministry of the Environment for applying pesticides in pest management. It is a legal requirement, and a serious technician shows it without hesitation.
