*Can take up to 8 weeks to hatch* All Carolina Egg Cases are FRESH the season and they hatch out a lot of mantis! Top Educational Project for The Classroom or At Home. Carolina Praying Mantis are also a benefit in the green house or garden. The Carolina Mantis Eggs (Ootheca) come attached to a stick with coconut fiber to help maintain a proper moisture level. They will come packed in their own hatching container. Simply remove the packing. The Carolina Ootheca should be lightly misted every other day as they need some moisture to hatch. Do not place near a heat source that is over 80 degrees F. Do not keep the Mantis Egg under 65 degrees F. Ideally the temperature should be between 75- and 80-degrees F.

Guarantee: WE DO GUARANTEE HATCHING We do what others don't do....that is we do guarantee hatching of your eggs. Even though we have no control over the hatching process, we want all of our customers to be happy with their purchase. Therefore, if after the allotted time, your egg cases do not hatch, all we ask is that you reach out to us personally and send us a photo of the mantis egg cases cut in half so we can see inside the mantis eggs. This will help us with quality control. We will send one replacement per unhatched egg. Your replacement will be for the egg only, so please keep your hatching cup. Things to keep in mind when hatching your egg case: If the egg dries out it will not hatch. If it is placed in direct sunlight and gets too hot it will not hatch. If it is kept too wet, it will not hatch. Some have put the egg case in a freezer thinking this would be the best way to store them until they hatch; that will destroy the mantis nymphs.
