What can i give my baby leopard gecko as a treat?

I want to give him a treat, i wanted to know if i could give him something from my garden.

Noooo! Do NOT give your geckos insects from your garden or anywhere from outside!! It could very easily kill your gecko if its carrying anything...try your local pets store and buy some wax worms, leopard geckos go nuts over those things! Just don't give him too much or he can become obese.
