“Excellent mouse extermination service! Very professional, punctual and reassuring technician. He took the time to inspect the house, find the entry points and explain every step of the treatment. Since the visit, no more noises or signs of mice. Clean, fast and effective work. I highly recommend this company to anyone with a rodent problem!”

Why treat the outside 3 times a year?

Insect infestations usually don’t start inside your home. Given enough time and opportunity, pests from outside will find a way into your home. Homes should be treated 3 times a year for continuous protection during the summer season.

Which pests do you treat in homes?

Fleas, ants, woodlice, spiders, grain beetles, cockroaches, earwigs, wasps, bed bugs, mice, rats, carpenter ants and other critters. To learn how to spot carpenter ants, watch our video (in French): carpenter ants, a hidden danger that threatens your home.

Why call a professional service?

Prevention and control of at-risk areas, safety and health (some pests can pose risks such as insect bites, allergies and diseases), specialized techniques, custom assessment and a 12-month written guarantee: if the problem persists, we come back at no extra charge, as long as the technician’s written recommendations are followed.

Are you certified?

Our certified technicians work professionally, efficiently and discreetly, 24 hours a day, 7 days a week. We hold a permit from Quebec’s Ministry of the Environment.

What should you do while waiting for the technician?

No need to panic. Avoid store-bought insecticides: they can scatter some insects and make identification harder. Note where and when you see the pests, keep food in closed containers and, if possible, keep a specimen in a closed jar. These clues help the technician target the treatment from the first visit. If you have children or pets, keep them away from the affected areas and mention it to the technician when you call. After the visit, the technician leaves you written recommendations to keep the pests from coming back.

How can I keep pests out of my home between visits?

Residential pest control works best when it’s paired with a few good habits: store food in airtight containers, take out the garbage often and keep bins closed, fix leaks and reduce humidity in the basement, and seal cracks around the foundation, pipes, doors and windows. Outside, keep firewood, compost and vegetation away from the walls of the house, and pick up fallen fruit and pet food. Inspect boxes and second-hand furniture before bringing them inside, since some pests travel that way. After each visit, our technician leaves you written recommendations adapted to your home.

How much does the service cost?

The price depends on the pest and the size of the infestation. The final price is set on site, after the inspection. Call us at 1·888·582·2191.
