I have a yellow jacket nest in my kitchen window. It is up in a corner where the window was never properly trimmed by the previous owner. I never really noticed until we had the problem. The easiest solution to my problem is to wait until fall for the yellow jackets to go away or dormant whatever it is and seal the hole. The problem is that my poor DH was doing me a favor the other day by nailing my stained glass back into the corner of the window. Unfortunately, he went too deep in the wrong direction and cracked the glass. Now the window has to come out to be repaired. I have tried two sprays from Lowe's that promise to kill. One kills on contact and the other is a blanketing foam. I have been using both for two days and they are still going strong. When I see them flying around the window I open the door and spray them (about 6-10 feet away). But now I swear they know that I am coming. The moment I open the door they all disappear. A few minutes after I am gone they are all at the window again. I am at my wits end. I do not want to call an exterminator because I have read multiple stories of people who did and the problem persisted until fall. I am going to try to set up traps outside the window to cut down on the numbers but I have read that it can be in the thousands. I would like to wait until fall but I am afraid that rain will leak into the window or that cold weather will spread the cracks. I am half tempted to seal the cracks with silicone like what you use on fish tanks. It will look horrible but will be efficient until fall. Any ideas??
