I have used the electic traps for mice and they work really well! No messy bodies or traps to touch. No poison for the pets. Just cute, *dead*, mice, dumped in the woods.
Yes, they are expensive, but they are reusable forever.
Also, I know that mothballs thrown under a porch will keep out wild critters like skunks and possum. I don’t know if it works with rats or not.
Thanks Grammy.
