My pond has so many wasps buzzing around it . The last couple of summers we have had tons of dragonflies around the pond but this year I've only seen a couple here and there. I'm sure it has to do with the wasps . Hubby found seven hives in the horse trailer with he sprayed when it got dark. We also found small ones under our umbrella on the deck that we got rid of, also a small one in the sailboat that hubby found today behide a curtain that he will spray tonight. And under the eves of the house there's a few openings that we see them crawling into. That ones going to be a little harder to get rid of, we're going to have to cover up the openings and hope they die.
