Hey that's very funny guys, very funny. I'm the one that started this thread, and now I just read that link; that says maybe I didn't get rid of them after all. The only way to seal this old building or to even start would be to pour a slab in the crawlspace, too expensive. Lots of other places for them to "squeeze through a hole the size of a dime"! It also says they get a tolerance to the poison, freakin wonderful.
Seems like they are gone, but I better get some glue traps much as I hate to make 'em suffer. But I didn't hesitate to poison them when the "scratch scratch scratch" started driving me crazy!
I love cats, but they come with their own set of problems...
