We have tons of worms in our backyard here in Washington. How do I know which ones are safe and which are bad?

Oh and I got some Herptivite vitamin supplement by Rep-Cal for the snakes does any one have any experience with this?

How in the heck are you getting them to eat fish fillets? I can't get my WC snake to eat anything that isn't moving around.

I have been feeding my cornsnake the same diet except more... It that OK?
