Friends of ours dealt with a rat infestation by feeding peanut butter and quick-crete. The rats were gone in a week.I'll go next pay day, to the big city, and get the ones that work. In the meantime, I thought maybe the peanut butter might work. I also wanted to give the plaster of paris mixture a try. Some say it works, others say it doesn't. Regardless, I will be getting the baits that I know will work, within a short time.
