some pet shops name mealworms wrong a local one I got worms from has small mealworms and large meal worms. when in fact the small mealworms were large mealworms and the large ones were them nasty giant mealworms my geckos wont eat and I dont blame them i for sure would stay away from them. as others have said order your worms from one of the many online stores. I use
www.wormman.com most of the time. I also used sunshine once.
