Hi, I've never had any worms die, maybe just 1 or 2. Mine are on oats that you buy from the store, sometime wheat bran. I also feed them carrots, lettuce, apples, bread, cereal etc. How is your humidity? Are the in the dark? Where are you buying them from? They will only drink as much water as they need. Do you have any mold growing? Too much heat will kill them, too cool and it slows down the process. Could very well be humidity or the feed.
