Red beans as a rat poison? Never heard of it. Why do people insist on trying these convoluted, unproven, complex methods when there are time tested solutions that everyone knows work?
Last spring, I had a stubborn and clever pack rat that was coming into one of my coops every night and dragging in all sorts of trash and refuse to make nests in the laying boxes. It was not attracted to food because no food is available overnight in my runs due to needing to prevent bears from being interested in breaking in. It just thought the coop was a very handy and attractive hotel.
The rat defied my usually very effective bucket roller trap. So I dragged out my trusty large spring rat traps and baited them with peanut butter. Got the darned critter finally.
Red beans. Makes my brain tired.
