What Can Crested Geckos Eat?

Complete food safety list — 20 foods reviewed with preparation tips and feeding frequency.

Safe — Occasionally (19)

Apples

Apples are non-toxic to crested geckos and safe as a rare treat, but their inverted calcium-to-phosphorus ratio (~0.5:1) and high sugar content (~10 g/100 g) disqualify them from regular rotation. Offer a few small pieces once or twice a month at most, always alongside a balanced commercial CGD paste.

Apricot

Apricot flesh is safe for crested geckos in very small amounts but its high sugar content and phosphorus-heavy calcium-to-phosphorus ratio (≈0.56:1) mean it should be offered no more than once a month. The pit is toxic and must always be discarded.

Banana

Banana is non-toxic to crested geckos and can be offered as an infrequent treat, but its heavily skewed calcium-to-phosphorus ratio (≈1:4) and high sugar content mean it should never become a dietary staple. Limit servings to once or twice a month alongside a complete crested gecko diet (CGD) base.

Blueberries

Blueberries are non-toxic and safe for crested geckos as an infrequent treat, but their unfavorable calcium-to-phosphorus ratio (roughly 1:2) means they should never replace a complete crested gecko diet (CGD). Limit offerings to once or twice a month and always pair them with a calcium-dusted staple.

Crickets

Crickets are a safe, nutritious protein boost for crested geckos when properly gut-loaded and calcium-dusted before feeding. They should supplement — not replace — a complete crested gecko diet (CGD) and be offered no more than 1–2 times per week.

Figs

Fresh figs are non-toxic to crested geckos and carry a favorable calcium-to-phosphorus ratio (~2.5:1), making them a nutritionally acceptable treat. Because figs are high in natural sugars, they should be offered no more than once or twice a month to prevent obesity and digestive upset.

Grapes

Grapes are non-toxic to crested geckos and can be offered as an infrequent treat, but their poor calcium-to-phosphorus ratio (~1:1.7) and high sugar content (≈16 g/100 g) rule them out as a dietary staple. Limit to once or twice a month alongside calcium-dusted insects and a balanced CGD to prevent metabolic bone disease.

Hornworms

Hornworms are safe and nutritious for crested geckos, delivering high moisture and a favorable calcium-to-phosphorus ratio rarely seen in feeder insects. Offer them no more than once or twice a month — excess water intake from overfeeding causes chronic loose stools and masks true hydration status.

Kiwi

Kiwi is non-toxic for crested geckos, but its unfavorable calcium-to-phosphorus ratio (~0.65:1) and moderate oxalate content cap it at a once-a-month treat. Always peel, dice small, and remove any uneaten portion within 24 hours.

Mango

Mango is safe for crested geckos as an occasional treat, but its high sugar content (~13.7 g per 100 g) and phosphorus-dominant calcium-to-phosphorus ratio (~0.8:1) mean it should never crowd out a balanced commercial crested gecko diet (CGD). Limit servings to once or twice per month and always dust with calcium powder.

Mealworms

Crested geckos can eat mealworms as an infrequent treat, but their high fat content and heavily phosphorus-skewed mineral ratio (roughly 1:7 Ca:P) make them a poor dietary staple. Limit to small juveniles-safe sizes, gut-load beforehand, and dust with calcium to partially offset the imbalance.

Papaya

Papaya is a safe, gecko-friendly fruit with a favorable calcium-to-phosphorus ratio near 2:1, making it one of the better fruit options for crested geckos. Offer it as an occasional supplement to a balanced crested gecko diet (CGD), not as a staple, due to its moderate sugar content.

Peaches

Peaches are non-toxic to crested geckos but their unfavorable calcium-to-phosphorus ratio (~1:3.3) and high sugar content (8.4 g/100 g) mean they should be offered at most once or twice a month as a small supplement to a balanced CGD-based diet. Remove the pit and skin before serving.

Pear

Crested geckos can safely eat pear as an occasional treat — roughly once or twice a month. Pear's high sugar content and unfavorable calcium-to-phosphorus ratio prevent it from being a dietary staple, but small peeled pieces pose no toxicity risk.

Raspberries

Raspberries are non-toxic to crested geckos and can be offered as an occasional treat, but their high natural sugar content and slightly phosphorus-heavy calcium-to-phosphorus ratio (~0.86:1) mean they should appear on the menu no more than once or twice a month. They must never substitute a complete commercial crested gecko diet (CGD).

Strawberries

Strawberries are non-toxic for crested geckos but their inverted calcium-to-phosphorus ratio and high sugar content make them a special treat at most once or twice a month. Always pair with a calcium-dusted staple diet to offset the phosphorus load.

Superworms

Superworms are safe for adult crested geckos in strict moderation — no more than once or twice a month — due to their high fat content and heavily imbalanced calcium-to-phosphorus ratio. Juveniles under six months should avoid them entirely until they are large enough to handle the prey safely.

Watermelon

Watermelon is non-toxic to crested geckos and can be offered as an infrequent treat, but its high sugar content and inverted calcium-to-phosphorus ratio (≈0.6:1) make it a poor dietary staple. Limit servings to a pea-sized piece no more than once or twice per month.

Waxworms

Waxworms are not toxic to crested geckos, but their very high fat content (≈22%) and poor calcium-to-phosphorus ratio make them suitable only as an infrequent treat. Offer no more than 1–2 waxworms once or twice a month to avoid obesity and nutritional imbalance.
