if scents are a big deal why isn't there a clear consenus among fishermen as to which scent is the best. anise vs shad, coffee vs craw?? you would think the fish would tell you. maybe they just prefer slippery stuff.
not sure if they work to catch fish but they do a decent job as bug spray.
We were getting skunked on birch pond one day around dusk. My friend tells me he is putting on bug spray, a few minutes later he hands me a bottle and tells me to try it, then casts. I don't look at the bottle and start spraying it on. He turns around and cracks up, he forgot to mention it was earthworm scent, not the bug spray he had used. He still chuckles when he pulls it out of his bag.
