You can get a plastic or glass tank.
An unclean tank may contain harmful bacteria or chemicals that could make your crickets sick. Do not use other chemical cleaners as they could be harmful to the crickets.
Without the proper habitat, crickets may fight each other for space.
Dead crickets and feces can make your crickets sick.
Make sure there are adequate air holes in the top of the box that you use to transport the crickets.
Crickets won’t overeat, so don’t worry about overfeeding them.
