How To Feed Gnats To Crested Geckos?

Gnats can be fed alive, dead, or blended.

Feeding live gnats to crested geckos can be tricky. Because their flying makes them evade a gecko easily. To prevent that from happening you will have the put the gnats and your gecko in a closed enclosure.

This will prevent the gnat from escaping making it easy for the gecko to catch. A tip before live feeding gnats is by gut loading them on fruits 12-24 hours before being fed to a crested gecko.

This significantly increases the nutritional value of the gnats.

Gnats can be fed dead. This removes the hassle that comes with live-feeding gnats. Furthermore, you can dust dead gnats with nutritional supplements.

This boosts the nutritional value. Gnats can be bought dead from the store or killed by high/cold temperatures.

Finally, you can feed gnats by blending them into a paste. This is the best way to feed gnats to young crested geckos. Furthermore, you can blend the gnats with fruits or other insects.


A handful of gnats is more than enough for an adult crested gecko. A half handful is enough for hatchling and juvenile crested geckos.


Gnats are small insects and are rarely bigger than a crested gecko’s head. Therefore, size shouldn’t be a problem when feeding gnats to a crested gecko.

Because geckos can eat insects equal to or smaller than the size of their head.

How Often?

Gnats can be fed as many times in a week or month to a crested gecko.

However, we recommend switching things up with other diets so your pet won’t be lacking in other nutrients or minerals.
