I had one still alive in a snap trap with it's back broken. Went and got a live trap and, with peanut butter, catch them. We then take them for a ride about a mile down the road and let them out. If they find their way back they deserve to get in. LOL Since we live in the country it is almost impossible to keep them out but I bought one of those electronic thingys that you put in the outlet last year and have not had any, that I know of anyway, get in since. The thing also works on ANTS which have been a huge problem several years ago. I also found that a white bowl set on the floor with a night light over it works as a GREAT FLEA trap!! Who would have thought?
