The wasps built their nest in the back garden in the cats’ enclosure and before I noticed it, they had begun to occupy it. That was a few months ago, and soon it grew longer. I knew they wouldn’t harm anyone if they were left alone, but I was worried the cats may leap at it. I kept a watch on the cats for a few days but they and the wasps paid no attention to each other. Then, as winter approached, by the beginning of November, the wasps departed.
Unnecessarily people knock down their nests or smoke them out. They disturb no one, if they are undisturbed, and help the environment too. In Dehradun, India.
