Why You Keep Seeing Spiders After "Treating" for Them in Keswick
Our guide Spiders in Your Home? Here's Why Spraying Baseboards Never Fixes It (An Ontario Exterminator Explains) covers this in full. This is the part that matters most when you check a home in Keswick.
- The technician sprayed visible webs and baseboards, but never injected pesticide into the wall void where the spiders and their prey were actually nesting.
- No one addressed the insect population (moths, flies, silverfish) the spiders were actually hunting.
- Egg sacs tucked behind furniture, in window tracks, or in wall voids were never located or removed.
- Exterior harborage, woodpiles, dense shrubs against the foundation, unsealed vents, kept feeding new spiders inside.
Named parks near the centre of Keswick include Gwendolyn Park, Keswick Beach Association and Purdy Beach Park, and spiders that live in green space can reach nearby homes along fences, gardens and tree lines.
