Release Instructions for Praying Mantis:

Once you have made it home with your insects, you may store them in a refrigerator but DO NOT FREEZE THEM. If stored in a refrigerator, the Mantis eggs will remain unhatched. However we recommend releasing before August. Hatching later than this may not give the baby Mantids time to mature and reproduce before the winter freeze. There are two different approaches to releasing, specifically designed for outdoor or indoor release. Each egg case will hatch about 50-200 baby Mantids.

 

Outdoor hatching: We recommend tying a string to the piece of the twig the egg case was originally spun around. Hang the egg case about 1 foot off the ground. Once the egg begins to hatch babies will crawl from between tiny flaps in the case and use a silken thread to climb down to the ground or onto surrounding plants. Once the egg has hatched it will be very hard to tell that it has hatched. The babies will disperse and find an area in your yard to call home and the egg case will look the same to most untrained eyes. If you want to make sure they hatch we recommend using the indoor hatching application.

 

Indoor hatching: Place the eggs of the Praying Mantids in separate clear containers and keep them in a warm place out of direct sunlight. Praying Mantids eggs need at least to be in 70 degrees for 2-3 weeks to get through their incubation period to hatch. However do be patient for it can take up to 8 weeks to hatch, depending on when the mother Praying Mantids have laid their eggs.

Praying Mantids eggs are a large spongy case that protects the eggs that the female Mantids attach onto leaves or branches. When hatching, the young Mantids crawl from between tiny flaps in the egg case and hang from silken threads about 2 inches below the egg case. After drying out, the young will disperse into their surroundings. This will happen within an hour or two. It is very difficult to know if hatching has occurred, unless the elusive and well camouflaged young are found.
