Plastic totes just give them more to chew on. And a mouse or rat can make that 12" jump. Get rid of their food source, get rid of the rats and mice. Make them scatter and scrounge hard for a living in the wild where the predators will make short work of them.I put everything into a container. I mean everything..tarps...tools, anything plastic, anything they could chew on or pee on, because they would chew and pee on anything, even the plastic tote I put my stuff in. They ate my life jackets before I could save them. And I stated this earlier, my feeder was hanging 12 inches off the ground!!!
