What Do Geckos Eat?

Originating from the Gekkonidae family, Geckos are insectivorous, or insect eaters. This makes it slightly easier for gecko owners and caretakers to ensure geckos get a similar diet in captivity. At, we help lizard caretakers learn more about the nutritional needs of their pets and help them find out what geckos eat.

If you’d like to learn how to create a nutritionally complete diet for your gecko, read on.

What Do Geckos Eat in the Wild?

Wild geckos are known to eat anything that is smaller than them so that they can easily overpower and eat it. This includes crickets, spiders, small rodents, spiders, grasshoppers--and even hatchling fellow geckos.

What Do Geckos Eat in Captivity?

While in captivity, geckos should typically be fed size-appropriate crickets along with occasional waxworms and mealworms as treats (this is good for them as they are high in fat). This cricket foundation works for all geckos because the large variety of worms that different species prefer differs greatly and may not provide them Although this isn’t an exact duplication of their diet in the wild, it is similar and will provide them the nutrients they need.

A good rule of thumb to remember is to make sure to not feed an insect to a Gecko that is larger than the size of its head. This will help to prevent choking or digestive blocking for your gecko. There are some species of adult geckos that can even be fed an occasional pinky mouse. Again, geckos will pretty much eat any insect or small animal that they can fit in their mouths.

How To Feed Your Gecko

Adult geckos should be fed 2-10 crickets every other day while growing baby geckos can require 20 crickets. Again, geckos will pretty much eat any insect or small animal that they can fit in their mouths so use their heads as a reference when buying insects.

Dust over the insects once or twice a week before they are fed to your gecko: one that is just calcium/D3 and another that is a reptile multivitamin. A small dish of pure calcium should also be left Gecko’s environment at all times.

Once a Gecko reaches its full adult size you can begin to introduce frozen pinky mice into their diets to keep them in their prime.

Make sure that when you are feeding your geckos they aren't eating their surroundings (sand, etc.) as well - this can lead to serious gut impactions. Some people recommend feeding lizards in another cage that has newspaper or paper towels as a base layer.

Remember, never leave insects in a gecko’s cage for more than a half hour, they can bite the gecko, and these bites can become nasty sore that have a potential for infection.

Also, don’t forget to keep your gecko hydrated. Geckos, like humans, need access to water. A small flat dish should be plenty; we don’t want to include a body-sized dish-- they’ll think it’s bath time and contaminate their drinking water!
