Ecological Note: Spiders play a crucial role in pest control. A single spider can consume hundreds of insects per year. Consider relocating spiders outdoors rather than killing them, or simply leaving them in areas where they don't interfere with daily life (like basements or garages).
Spider Prevention Strategies
Reduce clutter in basements, attics, and storage areas
Seal cracks and gaps around windows, doors, and foundations
Install or repair window screens to prevent entry
Remove vegetation and debris from around the foundation
Reduce outdoor lighting that attracts insects (spider food)
Use weatherstripping on doors and windows
Store items in sealed plastic containers rather than cardboard
Regularly vacuum corners, baseboards, and under furniture
Natural Spider Deterrents
Peppermint Oil
Mix 10-15 drops with water in spray bottle for natural repellent
Chestnuts
Place near entry points; spiders reportedly avoid them
Cedar
Cedar chips or oil have natural spider-repelling properties
Citrus Peels
Rub lemon or orange peels on surfaces to deter spiders
Vinegar Solution
Equal parts water and vinegar as a cleaning spray
Effectiveness Note: Natural deterrents have varying levels of effectiveness and work best as part of a comprehensive prevention strategy combined with good housekeeping practices.
Spider Control in Calgary — What You Need to Know
Spiders are one of the most common household pests in Calgary, especially during late summer and fall when they seek warm shelter indoors. While most spiders in Alberta are harmless, their webs, droppings, and presence can be a nuisance — and for homeowners with arachnophobia, even a single spider can cause significant distress. Calgary Pest Guard provides professional spider control services that include identification, web removal, targeted treatment of entry points, and prevention strategies to keep spiders out of your home long-term.
Calgary's spider population peaks in August through October, when temperatures drop and spiders move indoors. The most common species found in Calgary homes include house spiders, wolf spiders, jumping spiders, and cellar spiders. None of these species are dangerous to humans, but their webs can collect dust and debris, and large wolf spiders can be alarming when they scurry across floors. Professional spider control targets the areas where spiders enter and nest — cracks in foundations, gaps around windows and doors, and dark undisturbed areas like basements, attics, and storage rooms.
Effective spider control goes beyond just killing visible spiders. Our technicians identify and seal entry points, remove existing webs and egg sacs, apply targeted treatments to cracks and crevices where spiders hide, and provide recommendations for reducing the insect populations that spiders feed on. This comprehensive approach ensures long-term spider prevention rather than just a temporary fix. Call (825) 760-5364 for a free spider control quote.
Spider Control Calgary — FAQ
Are spiders in Calgary dangerous?
No. Calgary has very few dangerous spider species. The spiders commonly found in Calgary homes — house spiders, wolf spiders, jumping spiders, and cellar spiders — are all harmless to humans. However, their webs and presence can be a nuisance, and some people have severe arachnophobia that justifies professional control.
How much does spider control cost in Calgary?
Spider control typically starts at $250-$400 depending on the size of the property and severity of the problem. Treatment includes web removal, crack and crevice treatment, entry point sealing, and prevention advice. For a free quote specific to your home, call (825) 760-5364.
How long does spider treatment last?
Professional spider treatment provides 2-3 months of protection. We recommend quarterly treatments for homes with recurring spider problems, especially in late summer when spiders are most active indoors. Prevention strategies like sealing cracks and reducing outdoor lighting can extend effectiveness.
Is spider control safe for pets and children?
Yes. We use targeted treatments applied to cracks, crevices, and entry points — not broadcast spraying. Products are applied in areas where spiders hide and travel, minimizing exposure to living spaces. We provide clear re-entry instructions and offer eco-friendly options upon request.
