Hello everybody! Currently I feed my Hyla Cinereas three different food items. Crickets are their main staple, and occasionally I feed them mini mealworms and waxworms just to vary it up a bit. However, my waxworms die pretty fast; they only live for a few weeks (I feed very few during this time because of their high fat content). So the question is, how do I keep them alive? I refrigerate them in about 42 degrees Fahrenheit.

In the case that I can't keep the waxworms alive, I was thinking about completely removing them from the frogs' diet, and instead feeding them something else (something that's also healthier). I know nightcrawlers are often recommended; however, I don't have the heart to cut them up into smaller pieces while they are still alive to feed to the frogs. Roaches I don't feel comfortable with. As for fruit flies, I (and my mom) don't want to take the risk of them escaping into the home. So is there any other insect (I'm thinking some kind of worm?) that I could feed the frogs in substitute of the waxworms? I want the frogs to have at least three different feeder items in their diet.

Thanks for any advice!
