Spiders, ants and crawling insects often invade the exterior walls and entrances of homes in Greater Montreal. To keep them from settling in, an exterior treatment works well: instead of waiting for an infestation, you create a barrier right where insects come through.
What an exterior treatment does
The technician sprays registered products on exterior walls, around doors and windows, and on soffits, decks and other problem areas. This barrier works through the season against spiders, ants, earwigs, sowbugs and other bugs trying to get in. The result: clean exterior walls, fewer insects inside and, in turn, fewer spiders.

Why every year
Insects breed fast, and outdoor populations come back every season. A yearly treatment, done at the right time, keeps the protection going from one year to the next. It's especially useful for homes with a deck or pool, apartment buildings, restaurant patios and businesses with storefront windows.
Getting the timing right
Ideally early in the warm season, as soon as insects become active. Depending on your situation, the technician will tell you the most effective time and, if needed, when to schedule a touch-up during the season.
Making the treatment last longer
- Seal cracks in the foundation and repair screens.
- Keep firewood, thick mulch and debris away from the walls.
- Cut back on outdoor lighting that draws insects to your doors.
- Keep eavestroughs clear and avoid standing water.
Precautions for your family
The products are registered and targeted at the areas most at risk, in compliance with federal, provincial and municipal laws and regulations. The technician will tell you what precautions to take, including how long to wait before using the deck again.
