I bought a preying mantis egg case a few weeks ago thinking it would be fun to watch the babies hatch from it. I kept the egg case in in an aquarium closed off with a screen top. Unbeknownst to me, the baby praying mantises are so tiny they can fit through the holes of a screen. Now I have hundreds of these things hopping around my house. What should I do now? I really don't want to kill them, but I may not have any other choice.
