In late summer I had a bees/wasp nest in the ground in the duck enclosure, but in the furthest corner away from them. I ended up hanging up a bee/wasp trap with 3 different attractants in it. This reduced the amount of flying ones to almost none. Now is winter and nothing is flying around and I thought the nest was gone for sure. Boy was I wrong. The 9 ducks found it and dug it up completely. They ate everything that was dormant and sleeping in it. Good duckies!!! Now I'm sure the nest is gone for sure. No survivors means no off springs next year. This also tells me that I have to take on beekeeping away from the duckies. No problem with 22 acres.
