I have seen these Crawfish traps in walmart for 5$ a piece and I was wondering if anone has used them. They are only like 1' by 1'. I thought it would be more economical to just buy one rather than spend hours trying to make one. I do want to know some different designs for Crawfish traps if anyone would like to share them with me. Oh ya, does anyone here ever have problems with snakes getting in your traps and eating all your bait? That just eritates the heck out of me.
