Good idea but no, I bought larva with no adults. They are now all adults. Still no eggs or larva unless the adults are eating them as fast as they come. I've tried picking the adults out and putting them in a different container so any eggs could develop. Several times. I still put cut potatoes or carrots in all the containers in case it takes a long time to get larva big enough for me to see. Still nothing. The adults seem to be doing well.Hey, I read that some mealworms are treated so that they don’t pupate… could this be your reason for only adults?!
