Awesome book. If you have extensive rodent problems, this book is a must have book. I have been in this business since 1982 and mice and rats have most always been my public enemy #1. What I have learned from this book has increased my success rate for trapping and baiting rodents. I highly praise this book and feel it is for PMPs that want a better succes rate for baiting and trapping rodents, especially mice and rats.
