Cicada killers are ground nesters. They bore a hole into the ground and lay their eggs in a cicada (locust) that they have buried. Killing the adult cicada killers can be a futile task. The only thing you can do is to try to find the ground holes and treat them with a product such as Bifen. Saturate the holes and the ground around it. Killing the adult cicada killers may not be possible unless you can hit them directly with either Bifen or wasp spray. They are very fast fliers and hitting them with any chemical will be a lesson in target practice.
