Garages offer shelter, insects, and dark corners, making them prime real estate for Ontario spiders. Follow our guide to clean out your garage and keep it spider-free.
Your garage is an extension of your home's exterior environment but protected from the weather. Spiders enter through gaps around garage doors and set up webs near light sources that attract their insect prey. Cluttered corners, tool benches, and stored cardboard boxes provide the undisturbed breeding habitats they love.
Standard garage lighting attracts flies, moths, and mosquitoes, drawing spiders to build webs directly around doorways and windows.
Cardboard boxes, stacked tires, and lawn gear offer protected spaces where spiders can spin webs and lay egg sacs safely.
Worn garage door bottom seals and gaps around side entry doors allow crawling insects and spiders to walk right inside.
Clean out existing infestations and establish long-term protection with these active steps:
If your garage has become an intimidating zone of webs and crawling spiders, our licensed technicians can clear it out and prevent their return.
We sweep the entire garage ceiling, joists, corners, and under tool benches to clear out all active webs, spiders, and egg sacs.
We treat the inside perimeter baseboards, door tracks, and window frames. Outside, we apply a high-durability residual barrier around the garage doors, entry door frames, and foundation lines to stop spiders before they enter.
What types of spiders live in Ontario garages?
The most common garage residents are common house spiders, cellar spiders, wolf spiders, and funnel weavers. Wolf spiders are particularly active on garage floors during the late summer and fall.
Do garage spiders move into the house?
Yes. Garages often share entry doors with the main house. When temperatures drop in the fall, spiders in the garage will seek warmth and crawl under doors into your living areas.
Are black widows found in Ontario garages?
Northern Black Widows are native to Ontario but are rare. They prefer dark, undisturbed dry spaces like woodpiles, outhouses, or the back corners of old garages. If you suspect a black widow infestation, contact a professional exterminator immediately.
