If you suspect your worms to be in an environment which is too dry for them, then after a while they may start to suffer from dehydration. 85% of the weight of a worm is water and they can loose 70% of their body weight without dying. First aid for a dehydrated worms involves putting them in a glass of water for a few hours, while you rectify the wormery conditions, then put them back in the wormery.

One of my worms escaped and dried out. I put it in a glass of water and it has started moving again. Thank you.
