The other posters had very good points, but if you only have a few leos, I would keep this in mind. It has been my experience that most of my adult leos will not eat full sized mealworms. Only one of my 16 adult leos enjoys supers, and he could eat them all day if given the chance. This is by no means a scientific study, just what I’ve seen in my geckos. If at all possible, I would try to find a local pet store or bait shop that could provide you with a small quantity of superworms. My Petco has them in a 20 pack, for a few dollars, and they are two miles down the road. This way if your geckos don’t like them much, you won’t be stuck with a lot like I was. They are very easy to care for, just keep them at room temp. They need some high quality food, so they are nutrition to your leos. Best of luck, and let us know how it turns out.
