For the first time in seven years, I've killed three American paper wasps (thin-waist, black/dark-red-brown striping) in my chicken coop. I suppose they were trying to set up a nest, but I haven't found the nest yet. If one of the wasps I killed was the queen, the problem might be nipped in the bud. Every since I got stung three times in less than two months one summer by paper wasps (requiring treatment with steroids, which cause their own problems), I will NOT allow wasps nests near humans. Honeybees, bumblebees, mason bees, mud dauber wasps, etc. are just fine, but all paper wasps, hornets, and yellowjackets will absolutely be eradicated. Anyone else running into hazardous stinging insects in the coop? I'm pretty mad now. I don't like to use the sprays near my chickens (they're so poisonous!), but now I've stored a can in the storage area of the coop for quick access.
