Dude, I found 5 of the same kind on the front porch, one in my living room, and 3 on the back porch at the same time! I'm following this thread to see if someone has a suggestion.

One thing hat worked for us with spiders and scorpions was something called Demon WP that I picked up at a self-chem store. It's a powder that you mix in a sprayer with about 2 gallons of water. I sprayed a barrier along the baseboards inside the house and another one on the outside of the house. It worked for me. But, I want to see if someone has another idea.
