Once home, transfer your crickets into a "critter container" you can find at any pet store in the small animal reptile department. This is a clear container with porous removable lid. I would not recommend making your own container out of a large ice cream or Tupperware container, as they are not the correct dimensions. Your crickets need SPACE or they will die from one of the following; being smothered, not being able to find water or food, being eaten. Other options to accommodate your feeder insects are; large Tupperware containers which you can drill holes in for ventilation.
Pour your bag of bugs directly into the container. Then, place some clean egg cartons in with them (make sure you ask all your friends to save their empty egg crates). Then flush out their systems and "gut-load" them for at least 24 hours prior to feeding them to your chameleon.
