Earth Worms for Leopard Geckos?

Hello again everybody! I have a quick question again. I have two leopard geckos my female eats crickets and my male eats worms (meal worms, super worms, and wax worms as treats). Lately the prices of the worms have become outrageous. I have a few earth worms that I caught outside and they have now multiplied quite a bit. I was wondering if you can feed earth worms and night crawlers to leopard geckos?
