Formula 25 will give your live bait that extra element of scent you need to lure in those big cats. Not another spray, in fact this is not a spray at all. It is a solution that you soak your bait in before you use it. Use with shrimp, livers, cut bait, hot dogs, really any kind of catfish bait. Comes in an 8 oz. flip top bottle. Made by us – and used by us!
