I've done/tried it myself. Not too many times, but it did work on occasion. It didn't seem to work spraying it on live bait, but on lures. Large mouth bass and Northern. Sometimes it works. Or was it the lure/bait I was using???? Just like any of the gazzillion gadgets out there. If you use them enough, they'll usually work at least once. Maybe. It can mess up a lure also.............................................. ..............
