Spider Control That Keeps Them Outside
Spider Squad applies our professional-grade treatment to the full exterior perimeter of your home - targeting the foundation, soffits, eaves, window frames, and every gap where spiders harbour or enter. One visit. Results within hours.
The Spiders Most Often Getting Into Ontario Homes
Not all spider infestations look the same. The species determines where they're coming from, what's attracting them, and how targeted the treatment needs to be.
House & Cellar Spiders
The tangled-web spiders you find in corners, basements, and window frames. They're persistent colonizers - low light, high humidity zones indoors attract them year-round. A treated exterior perimeter eliminates the primary entry vector.
Wolf Spiders
Fast-moving ground hunters that don't spin webs. Wolf spiders enter through foundation gaps and door thresholds in late summer and fall while searching for prey and shelter. Large size (up to 30 mm) makes encounters unsettling even though they're harmless.
Jumping & Sac Spiders
Active hunters that move through wall cracks, window tracks, and door seals. Yellow sac spiders in particular tend to appear on walls and ceilings in fall. Both species are effectively controlled by the exterior perimeter barrier.
How Spider Control Works
Our treatment strategy addresses spiders where they enter and harbour - the exterior of the building - rather than chasing them indoors after the fact.
Step 1 - Full Foundation Perimeter
We apply our professional-grade treatment along the entire foundation line, covering the lower 2–3 feet of exterior wall and 1–2 feet of adjacent ground. Any spider crossing this zone to reach a wall or entry point contacts the active ingredient.
Step 2 - Eaves, Soffits & Upper Perimeter
Orb weavers and web-building spiders concentrate at eaves, soffit vents, and porch ceilings. We extend the treatment upward to address these high-traffic zones, which are responsible for most of the visible webs on the exterior.
Step 3 - Window Frames, Door Frames & Entry Points
Gaps around window sills, door thresholds, weep holes, pipe penetrations, and utility entries are the primary indoor access routes for wolf spiders, house spiders, and sac spiders. These points receive focused application.
Step 4 - our licensed treatment product Residual Barrier
our licensed treatment product is a professional bifenthrin suspension concentrate formulated for extended outdoor residency. The micro-encapsulated formulation bonds to exterior surfaces and remains effective for weeks, resisting UV exposure, rain, and irrigation without washing off or breaking down rapidly.
Web Cleanout Add-On: We can physically remove existing webs before or after treatment, giving you a clean baseline. Any new webs that appear post-treatment are immediately visible - and their absence confirms the barrier is working. Ask about web cleanout when booking.
Spider Activity Calendar - Ontario
Spiders are active year-round at some level, but entry pressure peaks predictably each year. Timing your treatment around these windows maximizes effectiveness.
The most effective treatment windows are late May to June (before populations peak) and late August (at peak pressure, before indoor migration begins). An annual plan puts you on both windows automatically.
Professional Treatment vs. Store-Bought
| Factor | Spider Squad | DIY (Hardware Store) |
|---|---|---|
| Active Ingredient | Bifenthrin (our licensed treatment product) - professional grade | Typically cypermethrin or deltamethrin - lower concentration |
| Formulation | Micro-encapsulated suspension - weather-bonded residual | Water-based spray - breaks down rapidly outdoors |
| Coverage | Full perimeter including eaves and upper zones | Typically low-reach only |
| Residual Duration | 30–90 days | Days to 2 weeks outdoors |
| Respray Guarantee | ✓ Included within 2 weeks | ✕ No guarantee |
| Time Investment | None - we handle it | 2–4 hours of your time per application |
Store-bought products are formulated for indoor use or short outdoor exposure. Exterior surfaces break down active ingredients within days. Professional-grade formulations like our licensed treatment product are engineered to stay on rough masonry, painted wood, and porous surfaces for the long term.
Before Your Treatment
There's no prep required for a standard exterior treatment. However, a few simple steps in the days before your appointment maximize results:
🌿 Clear Vegetation Contact
Shrubs, vines, or branches touching the exterior wall create bridges past the treated zone. Trimming them back 6–12 inches before your appointment prevents spiders from bypassing the barrier entirely.
🚲 Move Deck Furniture & Stored Items
Patio furniture, firewood, storage bins, and garden equipment stored against the house give spiders harbouring sites directly adjacent to entry points. Moving them outward 2 feet lets the technician treat the full foundation zone.
