Tempo dust would be a good choice to help control the cicada killers. Tempo dust offers a pretty fast knockdown though you should note that it does not offer an instant knockdown. You may want to consider using a instant knockdown spray such as Eco PCO Jet-X. Eco PCO Jet-X provides instant knockdown and kill of stinging insects. The Jet Spray can be sprayed up to 15 ft. Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. Unfortunately there is no fool proof way to prevent cicada killer wasps.
