Here we have an example of a wolf spider. These are typically pretty fast runners. Right now he is affected by an insecticide. They'll set up camp inside the weep holes; that's the gap between the bricks that is established by the builder to let moisture out of your wall. You can see his fine, little threads of web in there. Problem is, often times they lay their eggs and their baby spiders inside the walls and then you see them inside your house.
So how do all those little spiders get inside your home? The ones that kind of run along, jump along the grass, they hunt organisms like these pincher bugs and other insects down-deep right along the foundation where the grass meets the foundation. What happens though is that these running hunting spiders will set up camp inside what we call the weep hole. That's a gap between the bricks that allows moist air to escape your wall; that moist air draws insects in. They'll set up camp and nest back there and unfortunately when they lay their eggs their eggs are inside your wall two to six hundred babies will then hatch inside the wall and you'll start seeing little tiny spiders running around the corners of your home. You also see little cobwebs set up in the corners. This is where it comes from. Bulwark Exterminating is the #1 pest control option for keeping pests out of your home.
