A 10-count bag of Gulp worms costs $5-6 here.
Many places carry them, including BPS/Cabela’s, Wal-mart, Amazon, and other sporting goods stores. I’ve used several different “Gulp” soft baits (minnows, night crawlers, red worms, liver, etc) and have had good luck. Some of those come in little plastic jars; others in resealable bags, but they all have the “stinky juice” on them and enough in the package to keep them wet for at least a year or more.
They are made by “Berkeley” and claim to have 400% more smell dispersion. I’ve never used ANYTHING stronger smelling! I believe that’s why they work so well.
Give ‘em a try!
If you Google Berkeley Gulp, it shows hundreds of available soft baits with Gulp juice.
