Bill, et. al. - Thanks for the informative replies. I was not so concerned about the whirligig beetles until they seemed to overrun the pond. I have hundreds, if not thousands, in a 1 1/3 acre pond. It just seems like too many. I appreciate the advice on HBG. I'll do the northern BG with RES instead. Maybe I should try HSB and WE as predators since they probably won't overrun the pond.

Thanks again for the great advice.

Walt.
