Stryker Wasp and Hornet Killer will kill wasps on contact up to 20 ft. away. For cicada killer wasps, it is commonly recommended to use Delta Dust in each individual burrow. 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 overwatering during their season will help prevent them. Unfortunately, there is no foolproof way to prevent cicada killer wasps.
