Use as cricket carrier or holding pen. Simply slide the tube out of the Exo Terra Cricket Pen and drop the flapper down to prevent escapes. If needed, cover the tube opening with one hand while transporting it to the terrarium or feeder. Remove your hand and lightly tap on the tube to release the appropriate number of crickets for feeding. Only one tube should be removed at a time to avoid crickets escaping. Crickets should be kept in a well-ventilated room at a temperature range between 21-23C (70-75F) with low humidity. Keep the cricket pen out of direct sunlight and cold drafts. Always keep the cricket pen clean and dry. High quality cricket food and water (gel) should be provided at all times, both of which should be offered in the shallow food and water dishes provided. Cleaning Instructions: It is necessary to clean the unit regularly. Remove all debris and waste and clean the entire unit with hot tap water.
