I actually picked up some nice pesticide free dirt today for my own earthworm colony.. I'm going to try keeping them in my fridge in a critter keeper.

It took me a while to get my frogs to eat reptomin too, I didn't feed them for days at a time and eventually they accepted it. I shake the bottle in front of the tank now and they start their little 'feed me' dance so just have patience and let them get hungry enough to accept it, once they start eating it, they'll be hooked.
