HELP!!! We have been overwhelmed by aggressive, biting greenhead flies this year. This is our 4th summer with our pool, and we've never had anything like this. I'm guessing it may be related to the very wet fall and summer last year, as well as a terribly wet spring and early summer this year. I know that areas along the mid-Atlantic coast and marshes and along the Eastern Shore deal with this every year, especially New Jersey. Anyone out there have any ideas/suggestions about how to combat these bloodthirsty pests? At this point, I'm open to anything and everything (up to and including napalm... No, not quite that desperate yet, but close!)
