North Shore Exterminator: Carpenter Ants, Mice and Wasps

We cover the whole North Shore: Laval, Terrebonne, Blainville, Saint-Jérôme, Repentigny and the towns between them. Indoor treatment starts at $399. Mice and rats start at $429 for a house. Call in the morning and there is often a slot the same day, depending on how the day is already booked.

Cities we serve on the North Shore

What the North Shore deals with

The North Shore is not built like the island. Most of it is detached houses and bungalows on wider lots, with garages, sheds and treed yards. That changes which pests show up and where they get in.

Carpenter ants

Mature trees near a house are the main reason carpenter ants are so common from Blainville through Saint-Jérôme. They nest in damp wood, a leaking deck ledger, a window frame or a fence post, and move indoors along branches that touch the roof. You usually see them swarm in May. Treatment starts at $399 indoors, or $229 for a single outdoor visit.

Field mice in autumn

Houses backing onto farmland or green space, common around Saint-Eustache, Deux-Montagnes and the edges of Terrebonne, get mice as soon as the fields are cut and the nights turn cold. They come in under garage doors and through gaps where the siding meets the foundation. Perimeter control is $299 and is worth more than repeat indoor treatments.

Wasps in late summer

Wasp calls peak in August on the North Shore, because there are more sheds, decks and soffits to build under than on the island. One nest is $189. If you have found more than one, the full-house treatment at $259 covers every nest we find.

Rats along the rivers

Properties near the Rivière des Mille Îles and the Rivière des Prairies see more rat activity than inland streets. If you are catching one rat rather than treating a population, that is $230.

What it costs

Prices are the same across the North Shore as they are on the island. No travel surcharge for Laval, Terrebonne or Blainville.

How fast can we get there?

Laval, Sainte-Thérèse, Boisbriand and Terrebonne are closest to us, so a morning call there often gets a slot the same day. Saint-Jérôme, Saint-Eustache and Deux-Montagnes are further out and may fall to the next morning. We will give you a real time when you call, not a maybe.

Questions we get from the North Shore

Do you charge extra to come off the island?

No. A Laval or Terrebonne call is the same price as a Montreal one.

My neighbour has the same problem. Should we book together?

For detached houses, no. Each property is treated on its own. For a semi-detached or a plex, yes, because the two units share walls and the pests move between them.

Are the products safe with kids and pets?

Yes, when applied properly. Our technicians are certified in Quebec, and we tell you exactly how long to stay out of a treated room before you go back in.

How Our Montreal North Shore Extermination Service Works

Inspection

A crucial part of each pest control service in Montreal North Shore is an inspection of the property. That way, the pest exterminator will be able to determine the type and severity of the infestation. Based on that, he will choose the most suitable treatment to resolve the pest problem.

Treatment

Depending on the type of the pest, it might include spraying or fogging of affected areas, targeted baiting, or sealing of small entry points. No matter the case, the Montreal North Shore pest exterminator will choose the proper course of action and help you eliminate the intruders.

Follow Up

Some infestations require more than one visit, and with our guaranteed pest control service, additional visits can be organised upon your request. After a certain time, the specialist will return and re-examine the property. If there are still signs of infestation, he will proceed with further treatment.

Prevention

Our Montreal North Shore pest specialist will share helpful advice and give you some tips on preventing further infestation. Following his recommendations will guarantee that your property won't be reinfested again and assure the best results from the pest control service.
