More on spiders for Wismer 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.
