The worm ranch thing got a lot of good reviews...it's just basically worm bedding, food, and a container to house the worms. Better than buying it all separately if it works...I might try it.
I put in old veggy left overs with mine sometimes. I just make sure it isn't really acidic stuff, like orange peels and pomegranate stuff. I had a batch of worms die when my mom put orange peels in the container. Salad stuff that doesn't have anything on it is good, the worms I used to have loved old lettuce.
Let's get something straight. Worms that we feed to our snakes don't eat scraps. That job is for red wigglers. Earth worms eat what has already been broken down by bacteria and composting worms. In other words they eat what has already been composted. Putting rotting scraps in with earthworms just invites mold and bacteria that will kill them.
From now on, I'll treat others like they treat me. Some will be glad, others should be scared
