When using a product like Permethrin SFR, the hornets would have to directly contact the treated areas to be affected. We recommend using a product such as Delta Dust Insecticide to apply directly to the bored holes, and this product can be reapplied every 2 weeks as necessary. You can use a Bellow Hand Duster to make the application. This way, the hornets will fly through the dust picking it up and carrying it on their bodies back to the nest. Please be sure to review the product label for more information and complete instructions.
Permethrin SFR 36.8% is labeled for use on cluster flies but as an outdoor broadcast application. Please take a few minutes to read over our article entitled: How To Get Rid of Cluster Flies.

Dusting the holes with something like Tempo 1% Dust will allow it to flow through the nest better than a liquidMany of our customers have used Delta Gard Granules to help limit the number of cicada killers in their yard with some success. Still, the only surefire way to get rid of them is to treat the individual burrows.
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.
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.

Permethrin also would not be recommended as the best option for caterpillars or worms in the soil nor is it labeled to be used on edible crops. Most caterpillar control comes from spraying the foliage of the plants they may try to ingest or damage during the first signs of insect activity during the season. A popular choice for this would be Southern Ag Thuricide.
