This might sound silly, but pets are amazing spider deterrents. Cats especially love to hunt them. It’s like having a furry little pest control agent who works for treats and belly rubs. Dogs will also sniff them out and bark like it’s a major national emergency.
Even if you don’t have a pet, just the smell of cat hair in certain areas can make spiders nervous. Not a science-backed trick for everyone, but it’s free entertainment if you’ve got a curious feline friend.
