Can Crested Geckos Eat Waxworms?

Can a Crested Gecko Eat Waxworms?

Yes — a crested gecko can eat waxworms, as an occasional treat rather than part of the regular diet.

Waxworms are 15–25% fat and 15–18% protein — among the fattiest feeder insects available. That is the whole story of how they should be used: they are a treat, a tool for putting weight on a thin animal, and a way to tempt something that has gone off its food. They are not a staple for anything.

How Many, and How Often

One waxworm once a week, alongside a proper prepared diet.

The Risk That Matters for a Crested Gecko

Crested geckos get most of their nutrition from prepared diet rather than insects, so a waxworm is a treat on top of a treat. Easy to overdo without noticing.

What to Feed Instead

The staple should be a complete prepared diet plus discoid roaches. Waxworms sit alongside a proper diet or they sit in the fridge — they do not replace anything.

When Waxworms Are Genuinely Useful

Three jobs, and they do all three well: putting weight on an underweight animal, tempting one that has stopped eating, and conditioning an animal before breeding. Outside those, there is usually a better feeder for the same meal.
