Wild Earthworms For Pac Man Frogs.

[Monza geckos]

personally i wouldn't take the risk but they can be very nutritional but i see where your coming from in my point of view to solve the parasite problem breed them a generation and then feed the young as they will be captive bred and be gutloaded which will minimise all risks or you could go on ebay and buy lob worms and night crawlers in bulk for cheap if there's no pet stores near that supplies them

I believe wild red wigglers (this is the species we have in most of the US) are mildly toxic.

Thanks everyone for your replies. I will pass on the earthworms.
