Do any of you have any problems with wasps nesting in your coops? Over the past several years, we have been having a huge problem with paper wasps building nests everywhere. They are the invasive European variety and are very aggressive. They have almost completely displaced the native wasps, which would generally build their nests in out of the way places. The European wasps build in or on anything that hasn't moved in a day or two, from ground level on up. I normally avoid spraying poison around, but have made an exception for these wasps. I eliminate every nest I find. I would not spray in or around a coop, though. As I am building my coop, I am trying to make it "wasp proof". It seems like the kind of structure they would like, though. They can get in through mesh as small as 1/4", so I may be wasting my time. Thoughts?
