We thought our fruit flies were a problem, but realized the real problem was the massive hornet infestation. On Monday we had dinner out on the patio, and before we were finished we were surrounded by hornets. We thought we knew where their nest was, but we were way off. When the exterminator came, he pointed out this very unsubtle nest on the farthest corner of the house. I don't know how we had missed it. Except perhaps that we didn't walk all the way around the house.
The exterminator made quick work of getting rid of the hornets and their nest, so we all should be spared stings.
