So we have a small critter cage for our crickets with the orange slice things used for both water, vitamins and food source for the crickets changed every day as well as an egg carton. We buy usually 20-30 at a time and within a night or 2, a majority are dead. They are kept in room temperature. What are we doing wrong?! Getting very tired of the daily trips to petsmart/petco!!! please help!
