I don't think it really matters but if you have more noisy crickets to get rid of, then by all means lol!

When I'm feeding crickets, I know it sounds bad, but since emperors ARE lousy hunters and slow, I pull one of the hind legs off each large cricket. Pull the fake plants out of the viv to give them less places to hide, and often try to offer it via feeding tongs first. That way, if my girl doesn't take it from me, at least they will be slow enough for her to catch them and they are a lot less likely to make noise.
