Rodents!

Living on a farm all my life, rodents were always a problem. We used a poison from Purina. It would make the critters leave the area in search of water, and we would never find the dead bodies. The barns did not have the Stinky mouse smell. However; the best way to stop is to fix the holes that they enter in the trailer. My mother was great at this. She would crawl around on the ground and find any place that looked like a hole and stuff steal wool in it. You can put lights in your rig, and crawl all around and if you see light shining through stuff steel wool.
