Spike is a little smaller than a wax worm. To me? They are hard to hook, they almost always pop open. I don't know if you can get them or not, but we've been using Butter Worms. Walmart had them for $3.96 for 20. A little pricy, but you can get 3-4 fish on one. They are a reddish yellow & bigger than a wax worm. We really been getting the panfish on them..Hope this helps a little..
