No they are insectivores which means they eat insects they never eat plants because i have a gecko my own and he doesn't eat the phoney baloney stuff. He only eats bugsActully, they are insectivores! That means they have a consistante diet of small insects. In a geckos case, crickets, meal worms, wax worms, super worms. Check your local pet store to find out what kind of gecko eats what.
The beaded gecko of the colenyx family are insectivores eating live prey.

A gecko's niche is probably that it eats mosquitoes to help other animals from them.
