What Can Crested Geckos Eat?

Hornworms are a safe, hydrating live feeder for crested geckos but their poor calcium-to-phosphorus ratio and very high moisture content make them a once- or twice-monthly treat, not a staple. Always dust with calcium powder and choose worms no wider than the space between the gecko's eyes.

Superworms are safe for adult crested geckos in strict moderation—no more than once or twice a month—because their high fat content (~17% dry weight) and severely phosphorus-skewed Ca:P ratio (~1:18) make them a nutritional liability as a staple. Always gut-load and dust with calcium + D3 before offering.
