Feeding and Nutrition


Leopard geckos are easy to feed, as long as you don’t mind feeding them live insects only. Leopard geckos will not eat any dead insects (many seem to not bother with insects unless they are wriggling and moving) and certainly will not eat a plant-based diet.

The main insects fed to leopard geckos are:

  • Crickets
  • Mealworms
  • Locusts
  • Dubia roaches
  • Waxworms (occasionally)
  • Superworms


It is important to “gut load” your insects at least 24 hours before feeding them to your leopard gecko. This means you’ll need to feed the insects with all the nutrients you want your gecko to ingest, which will then be passed onto your gecko when it eats the insect.

You should also dust the insects with calcium powder at every feeding, and about twice per week dust the insects with calcium combined with vitamin D3 powder. Leopard geckos can overdose on vitamin D3, so it is best to restrict this to a couple of times per week, however it is impossible for them to overdose on calcium, so it is safe to use calcium with each feed.

Quantity and Frequency

It is recommended that you feed baby and juvenile leopard geckos on a daily basis, however adults have a slower metabolism, therefore only need feeding every couple of days.

There is some debate over how many insects should be fed to your geckos, but geckos tend to stop eating when they’re full, so trying around 6-8 insects to begin with would be a good start to see the quantity needed per feed, and adjusting if necessary.
