I was cleaning my mantids tank and one of them jumped off my hand before i was able to transfer it to the clean holding tank. It ran across the floor and onto the curtains. When I got her she was weird. Her legs seemed to lose control and twist upside down. I recently had new neighbors move in and infested the building with bedbugs. In an effort to keep them under control until the exterminator got here I treated the area with Diatomaceous Earth. it is deadly to any creature with exoskel like my mantids. So I vacuumed it all from everything i saw it accumulated on but found out today that the curtains had a very thin film on them. Usually DE takes 48 hours to kill via dehydration, the pest. I have since washed all curtains in the house and will be doing blinds window panes etc. If not the DE could the spray the exterminator have taken affect that quickly??? What else would kill her like that she was stiffening up right before my eyes. So... I just freezered her. She was my last wide arm female. She made it to L3 without a problem.
