Fishbites Bag O Worms - Comes in both Fast Acting and Longer Lasting formulas. Maximum scent for minimum bucks is the motto for these Fast Acting baits. The rate of release and the percentage of stimulants have both been kicked up a notch in order to make the Fast Acting baits live up to their name. If target fish are plentiful and bait stealers are few, then the Fast Acting baits are a good bet.
