But first I had to trim away some of the shrubs growing up around the window frames . I trimmed other brush , too , because I was out in the yard working , anyway . Foul white flies and other winged pests flew up around me as I worked . I found a nest yellow - jackets in a hole by the apple tree , and killed them .

Question: How may they have killed the yellow jackets ?
Answer: They used a machine gun to spray them with lead .They used a fly swatter to scare them all away .None of the above choices .They used their hands to squish them till they died .
