An article that I read said a trap can be made out of a small box that's set outside. The box is to have holes poked in it all around the bottom...holes poked through with a pencil, because that's the size they prefer to crawl into...which is just about the size of an EAR opening.
I did sleep with cotton stuffed in my ears the other night! Just as I was about to get ready for bed I saw one of those critters. So I started runnin' around the house knocking on bedroom doors to hand out cotton balls.
