praying mantis egg case

I was gifted a praying mantis egg case by my secret santa. It’s a very thoughtful, awesome gift, but… 

1.) I have no way of knowing what species it’s from.
2.) I have never seen a praying mantis here and don’t know if they’re indigenous to the area.

When the babies hatch, there will be hundreds of them. What am I supposed to do? I can’t raise more than one to adulthood in captivity in my current living situation, and I don’t want to release a potentially invasive species. Should I just… keep them contained and let them eat each other until only one remains? Kill most of them? Find some way to ship them to someone in an area where they’re indigenous and have them release them?
