What to do with yellow jacket in house in winter?
Yellow Jackets over winter in a semi-dormant stage. They emerge when the weather gets warm enough. Every hornet that emerges in the spring has the potential of becoming a queen. So by destroying the early emerges, or the ones that get into your house you are effectively eliminating a nest. They are groggy when awoken before their emergence time. You can just catch it a rag or with gloves And put it outside and let nature take its course.
