When it comes to plastic worm fishing, I'd bet my last dollar that they're likely to list their favorites—in no particular order— as green pumpkin, watermelon, and black/blue. Well, a few of them might stray a bit and substitute watermelon candy for straight watermelon. Or they might swap green pumpkin with red flake for regular old "G.P.". . Step Three. When the baits are all clean, dry them and then put them in sealed plastic containers. Before you seal the tubs for good, take your favorite oil-based scent and squirt a bunch of it onto your baits and mix them around to make sure they’re evenly covered. Fred does this with his swim baits and bass worms.
