Our chicks have only been outside for a week, and about a week before that we discovered we have some mice in the basement, and a rat in the garden. Needless to say, over the course of two weeks, we've discovered we actually have mice throughout the house, and rats have even made their way in. We're in the city, in an old house, with partial basement/partial crawlspace, so blocking them from getting in has turned out to be nearly impossible. For the last week or so, I've been making 1:1 peanut butter/plaster of paris balls, and my husband has been trying to block whatever entry/exit point he can. Well, the peanut butter balls go like hotcakes, and I have yet to smell the 'sweet smell of success' (AKA-dead rotting rodent carcasses), and the target of my hard work are just digging lower and holes around the house keep reappearing. We've busted out the poison now, and snap traps (no luck on the traps)....but I guess my question is just as in the title....is there a chance it could take that long for the POP to work? I am certain they are being eaten by the truckloads, and would love to hear that it could actually take days or a week to kill, because I feel better about using this method than the poison, which I can only put in the crawlspace, to keep away from my 2yearold and 3 dogs. But I also hate the thought that I'm actually just creating protein packed super rats with bowels of steel. My next step will the be the bucket trap approach, but would love to avoid the sight of a drowned rat. All responses and experience are totally appreciated!
