First, let me say I have no personal experience with guineas!
Ok.. that out of the way
I looked them up a couple of days ago (also for bug killing properties) and what I read was that the females make a variety of noises, while the male only makes one and was, therefore, somewhat quieter.
Don't know how true that is, but wanted to pass the tidbit on to you! I'd love to know how the guineas work out for you.
