Grabbing them by their antennae and bulldogging them down to the table top is no easy matter either! And then, even if you manage to hold their feet still, your own fingers get in the way. I give up. Anyway, thats just too .... uhhh..."nitpicky!" I'm going to get one of those air guns that shoot rock salt, and take it to a whole nother level!
Just catch them and take their wings off. My wife used to catch them when she was little and take their wings off so they would have to walk, saying she would more relatives that way. (Her maiden name was Walk)
