Mantis nymphs from this site are sold as pets only. Please do not release them into the wild. They are not for pest control. If you are looking to purchase nymphs for pest control, please consult your local plant nursery or garden shop. They often carry local species ootheca to be hatched and used as a natural pest control.
I know it would be nice to have lots of orchid mantids on the orchid flowers in your garden, or Rose mantids in your rose garden, but it is highly illegal to release any non-native mantis species into the wild. I get many emails from people wanting to do such things and little do they realize the potential damage this could cause. It is quite disappointing to see the lack of care for the environment some people have.
If you have trouble finding ootheca for your garden locally, please feel free to contact me. I know of many places online to purchase them, even Ebay has some available.
