When I had ASF's they were like Tribbles and at the time I only had a couple snakes so I split the colony up and let them die of old age. Now that the collection has grown I will probably get a new group of ASFs since they are very prolific and several times I have found good deals on snakes that the seller claims are 'stuck' on live or ASFs. While my animals all eat f/t except the lizard eating vine snake having a live food source available could prove beneficial.
