Scotts GrubEx is not labeled to control cicadas. 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 over watering during their season will help prevent them. Unfortunately, there is no fool proof way to prevent cicada killer wasps.
We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young. The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.

Grubex would not be harmful to trees as it is only an insecticide that works as a contact kill on existing grubs and plant damaging insects the first 24-48 hours after you apply it.

Please see our Mole Control Guide and the appropriate treatment methods to eliminate them from your lawn in a more direct fashion.
