are your grubs always swarming? there are some on the unter all the brown stuff. If I dig I will find them. They only come out when there is food. I still have a lot of house fly larve. Food consumption is happening and I am still getting mature grubs so I am doing something right. I have been putting the mature ones in a bucket with sawdust. It rained a couple days ago and the sawdust got damp/ wet. I checked on it today and seems none of the larve are moving and have shrunk to the size of a tic tac. should I keep them in somehting different. do you think they died?
