Breeding Crickets
Crickets are the main food supply of most carnivorous and omnivorous lizards. The bill for constantly buying crickets can add up quickly. Crickets are the easiest insect food to breed, and if you have the space, a good idea.
Housing
For a small crop of crickets, a 40 gallon glass aquarium with a screen top is sufficient. As your 'colony' grows, increasing the size of the aquarium will be needed. Crickets need space as well as your lizards, as they can get stressed easily. You must give them a lot of standing room, so you must include empty egg cartons and empty toilet paper/paper towel rolls. This allows them a lot of standing room and hiding places. These must be changed whenever there is a lot of excrement covering them.Food & Water
You will want to provide the crickets a wide variety of food. The more nutrition you feed your crickets means they will be healthier, which in turn helps the lizards you are feeding. This is called 'gut-loading'. Provide your crickets with an assortment of fruits including apple slices, pears, small portions of oranges, slices of banana and cut grapes. For the vegetable side, shaved carrots, green leaves (avoid iceberg lettuce, it has no nutritional value), sweet potato, broccoli, beans, etc. Dry dog/cat food is also recommended as it is high in vitamins. You can also purchase pre-made cricket food from you local pet store to supplement the real food. Do not leave standing water in your cricket aquarium, as crickets have a habit of drowning in the smallest amount of water. You can use a hamster water bottle, stuffed with cotton, for the water. You should also mix a multi-vitamin supplement into the water supply.Breeding
Breeding crickets will require a substrate; something to lay their eggs within. You can cut the bottoms off of large pop bottles, but any small container will do. Line these with a damp substrate, like peat moss or potting soil. Keep the substrate damp, but not overly wet.Temperature
Keep the temperature of the cricket enclosure between 76 degrees F to 84 degrees F.
