Over time, cricket droppings will accumulate on the egg cartons and the cartons will need replacing. The egg cartons are most easily handled if they are glued together in sets of 4 or 5 for easy removal from the container. Feeding Feeding the crickets the right diet is important for two reasons. Firstly the crickets need adequate nutrition to survive and breed. Secondly, the nutrition from the crickets will be passed on to your reptiles or amphibians and so it is important to keep them healthy.
Crickets require a high-protein diet.
Without, and often with, an adequate diet the crickets will prey on each other. Commercial cricket foods are available in large and small quantities. The large sacks of cricket chow may not be available everywhere, check with a local feedshop. The smaller jars of cricket food sold at pet shops are very expensive and I have heard mixed results about some brand's quality and acceptability to the crickets. Tropical fish flakes have also been recommended as food but the expense is astronomical if you are raising a large number of crickets.
