I usually buy 1000 small BSFL from symptomBSF and I feed them the leftover greens my beardie doesn’t eat. But when they eat it, it fills the container with this black, sticky, smelly mucus and I have to clean the cage for the worms regularly. I have no interest in breeding them. Do I have to feed them? I usually only have them for a month or so since I have a baby beardie so will they last that long without food? Thanks
