Oh I see you have carpet. Putting Borax down (you can get it in grocery stores, WalMart, etc. in the laundry section NOT BORIC ACID, BORAX!!) for a few hours and then vacuum it up. Dispose of vacuum bag in outside garbage. I would even spray it down, seal it in a bag, and then dump it. I don't know if the spray would be okay for carpeting, as I don't have any THANK GOD
You may even have to resort to hiring a professional pest control company to help you with this, as carpet tends to complicate things. They can burrow deep down in there.
Good luck!!!!
