Actually, not any good enough experiences to warrant using them much. Have always had better luck with nightcrawlers or waxworms (for gills or crackers) ... with the nod to nightcrawlers as the better choice. Nightcrawlers are easily caught (free bait) and relatively inexpensive if bought. One nightcrawler serves as a minimum of 6 "pieces", that can be put on a hook or jig, and capable of catching several fish before replacement is necessary.
I think I've used quite a few different "live bait" offerings ... and the 'ol nightcrawler just seems to always produce, and occasionally produces bigger/better fish.
I've used : nightcrawlers, earthworms, redworms, grey crickets, grasshoppers, potato bug larvae, corn worms, stalk borer worms, waterbug cockroachs, Katydids, waxworms, mealworms, black crickets, and probably a few other critters that I can't recollect. Considering ease of obtaining, multiple catches on one whole or piece of any of these .... the nightcrawler comes out on top. That's not to say that mealworms don't catch fish, as I've actually caught a Crappie or two on them Thumbs Up ... but, for Bluegills, Shellcrackers, and various other Sunfish species (which is what I use "live bait" for, most often), I just can't seem to produce the numbers & size that I can with a piece of nightcrawler.
