The water dispenser is a commercial chick waterer which is essentially a plastic jar inverted over a circular trough which holds the water. Plastic scouring pads or Dacron quilt batting should be cut to fill the trough. They will soak up water, making it available to the crickets while preventing them from drowning. On top of these are placed two plastic tubs, such as sour cream or yogurt is purchased in. A heat pad is placed on top of the lid of the storage box to provide adequate warmth.
Crickets thrive at temperatures higher than the average house temperature.
If you place them in a warm herp room this should provide them with enough heat. At lower temperatures they will survive and even breed, but yields will be much reduced. They also seem to live longer at lower temperatures, something to keep in mind if you find yourself with an excess which you want to keep alive as long as possible. Maintenance of the breeding colony comprises of filling the food, keeping the nesting material damp and filling the water when empty. A 1 litre waterer will last 4-5 weeks.
