You can either give them to science teachers, friends, gardeners, sell them to people who want the egg cases to hatch for agricultural uses.
Step 3: First foods and molts.
Fruit Fly Cultures ~ The first type of feeder insects you will need to feed your mantis is the WINGLESS fruit fly species. USDA/APHIS approved Hybrid wingless fruit flies can not fly and will not populate in your home. No care needs to be provided for the fruit flies. Fruit flies are self sustaining and require no care on your part. You just keep them at room temperature (about 72 degrees) One culture is enough to feed up to 20 baby mantids for about 2 - 4 weeks! Simply tap about 4 to 12 fruit flies into the mantis container every 2 days or so for young mantids untill they outgrow the food at which time you will need to graduate the mantids to eating crickets and other larger insects.
