Fishbites do work with spots.....But I'm like you I think the feeding frenzy is what gets them to hit....A spot will usually hit most anything when they are running..........I've seen people use the other fishbites that come in different colors and scents and catch them too......Fishbites have a sandworm that is pink and chartreuse which I think they call the electric chicken......Thought I would give those a try this fall and see what happens..........
Cheat trick :::: Use a regular piece of nightcrawler and a small piece of fishbite together and your worm will catch alot of spot before having to put on more worm......The netting in the fishbites keep the worm from being snatch off the hook.......
Also the color choices you make depending on water clarity at the time they come in should help too........chartruese is a killer on any kindof fish.. Keep your bait moving and off the botom if possible.....
Pompano will also hit fishbites but thats another story.........
