These are professional strength glue traps that are easy to use. Mice simply step on and then cannot step off again. Begin by separating the traps and then placing glue side up near walls where mice run. Take a look to see if a mouse has taken his last step onto your glue board. Make sure you place these in multiple locations or move them after a few days. Simply throw away when done. No need to bait. These are ideal for attics, basements, garages and sheds.
