In captivity, feed a leopard gecko a mix of gut-loaded insects such as crickets, dubia roaches, and silkworms, dusted with calcium, every day for babies and two to three times a week for adults. Leopard geckos eat insects only, so they do not need fruit or vegetables.
Best staple insects
- Dubia roaches: high in protein and easy to keep.
- Crickets: a classic, though they can be noisy.
- Silkworms and hornworms: soft, moist foods that add variety.
Foods to limit
- Mealworms and superworms: okay in moderation, but hard shells and high fat make them a smaller part of the diet.
- Waxworms and butterworms: treats only, one or two a week at most.
How much and how often
| Age | Frequency | Amount |
|---|---|---|
| Baby (under 4 months) | Daily | 5 to 7 small insects |
| Juvenile | Daily or every other day | As many as eaten in 15 minutes |
| Adult | 2 to 3 times a week | 5 to 8 medium insects |
These numbers are a starting point. Adjust based on your gecko’s body and tail condition. A healthy tail is plump but not bulging.
Supplements
Dust insects lightly with calcium at most feedings. Use a multivitamin once or twice a week, following the package. If your gecko has UVB lighting, a vet may suggest using calcium without D3 on most days. Ask your vet to tailor this.
Size and safety
Insects should be no larger than the space between your gecko’s eyes. Do not use wild-caught bugs from the yard, which may carry pesticides or parasites. Remove uneaten crickets so they do not bite your gecko.
Water
Provide a shallow dish of fresh water at all times and clean it daily. Keep a humid hide for shedding.

Bottom Line
A leopard gecko thrives on variety, proper size prey, and calcium. Contact an exotics vet if your gecko shows tremors, a thin tail, or refuses food for more than a couple of weeks.
