I am having the same problem. I live in a rented house and go to college. The owners put poison out but my dog got ahold of the poison and had to be taken to the emergency clinic. I then took the poison out of my house. NOW I have a nice BIG friend that I want to get rid of. I got traps and have just learned of teh Electronic Pest Control so I am going to try that but I need help to. I want them gone.
