Some brands even include insect protein for optimal nutrition. To be most beneficial, supplement with live insects at least once every week.


Freeze-Dried Worms

Crested geckos are omnivorous creatures and may consume various feeder insects and fruits as well as greens and other vegetables. Crickets or insects with low levels of fat should make up a bulk of their diet.

An insect and worm variety will provide your crested gecko with protein while also providing her with essential vitamins and minerals. Avoid feeding mealworms, maggots or wax moth larvae (commonly referred to as “nymphs”) which have hard exoskeletons which could potentially impair digestion.

Consider offering dubia roaches or other small feeder cockroaches that are easy to care for and rich in nutrients as feeders for your crested gecko. In addition to food, your crested gecko needs plenty of water; an ideal shallow dish should be provided so she can drink daily from it. Misting can help maintain humidity within her enclosure.


Crested geckos must be provided with a variety of feeder insects and worms as they all offer different vitamins. While crickets may have become the traditional food source for gecko feeders, other feeder insects should also be added into its diet for maximum benefit.

Waxworm (Ladybug or lesser wax moth larva), another popular feeder insect, provides protein and fat. Unfortunately, however, their high phosphorous levels mean they should only be given as treats to your crested gecko.

Misting your crested gecko’s tank regularly to maintain high humidity levels and prevent fungus and other health problems, fruit smoothies or purees may be offered as secondary foods; just avoid anything with citric acid or added sugar that contains citrate or contains citric acid as they could contain citric acid and add unnecessary sugar content to their diets. Offering homemade recipes once or twice monthly or when running out of commercial crested gecko food mix is ideal.

Butter Grubs

As homemade crested gecko food, butter grubs make an ideal treat. Packed full of healthy vitamins and minerals from fruits and berries as well as protein from whey, they come in various flavors to suit different crested geckos’ preferences.

Alternative diets provide an excellent way to provide their crested geckos with essential calcium and vitamin D3 supplements, though supplemental feedings should still be supplemented regularly to prevent Metabolic Bone Disorder or other health problems caused by vitamin deficiency. An easy way to do so is by dusting feeder insects with calcium powder supplement before feeding them to their crested gecko.

Some fruits and berries contain high concentrations of oxalic acid, which binds calcium and prevents its absorption. Therefore, it’s wise to limit consumption of blueberries and figs. A more nutritious choice would be making a green smoothie from various vegetables such as escarole, endive, alfalfa or dandelion greens.

Commercial Mixes

Crested geckos are fruit eaters, yet need additional protein, vitamins, and minerals in their diet. Commercial crested gecko food offers an ideal solution to this dilemma as it was specifically formulated with their needs in mind.

These complete diets typically come in powder form that can be mixed with water to form a paste- or smoothie-like consistency, usually made available through pet food companies like Repashy or Pangea Diet.

These commercial mixes should be offered three to four times weekly along with live insects, and should include various safe fruits like mangoes, peaches, berries and pears cut up or mashed before feeding. Oxalic acid-containing fruit should be avoided as this may bind calcium absorption.

Avocados and apples may also be given on an occasional basis as treats; watermelons should only be given as special occasions.
