Query: Did not kill anything

I bought the rat zapper a couple months back because some rats got into my basement an made themselves at home. Months later they are still living there and the rat zapper has not killed a single one. I baited it with peanut butter like others and after a week nothing so I thought to myself maybe the rats are to smart to go in. I decided to try a more attractive bait so I put a small piece of colby jack cheese in the back and a tiny piece of chicken. I figured the rat could not resist. About a month later still no flashing lights and I pick up the zapper and the cheese and chicken are gone. I turned the zapper off and on again to see if the battery had died and the light turned green indicating that the battery was still good. I dont know about others that bought this but either this dont work or mines is defective.
