More on spiders for Richmond Hill homeowners
The chain is simple: light attracts insects, insects become prey, and spiders position themselves where the hunting is good. If the same window or light fixture keeps producing webs, it's telling you that location consistently produces insects, not that the spider has any particular interest in your siding or trim. Why Spiders Are Inside Your Home (And What They're Actually Following)
Although centipedes have poisonous glands and may bite, their venom is not poisonous to humans or pets, and the type found in Canadian homes typically does not have the jaw strength required to pierce the skin easily. So the reason to treat them isn't personal safety. Centipedes in Your Basement? Here's What They're Actually Telling You
The better question isn't "what does my house have that spiders love?" It's "what is attracting the spiders here?" Spiders are hunters, not scavengers looking for crumbs. A clean home with an active insect population outside can have just as many spiders as a messy one. Why Spiders Are Inside Your Home (And What They're Actually Following)
