Hi everybody, i have a few questions about worms as food for garters:

1.- Can i feed a garter with common earthworms or there is a special kind of worms?
2.- Are they parasit safe?, if not, What kind of parasites can contain the worms?

The reason for this questions is that i want to make a earthworm breeder to feed mi garter but i dont know very much about this kind of food.

Thanks, ill be waiting for an answer.
