Talstar P will kill Cicada Killer that come into contact with treated areas for a sufficient amount of time to receive a lethal dose. You will need to dilute 1 fl oz of Talstar P per gallon of water and broadcast spray over the areas where you have noticed activity. Most folks notice only very limited results from broadcast sprays of insecticides for cicada killers because they don't land and walk around for a long enough time before entering their underground burrow. Please read below for the most effective treatment method:
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.For prevention you can try to use a granular insecticide such as Talstar PL Granules in the couple of weeks before this pest is known to emerge. For current infestations, you would need to use Delta dust in each individual burrow.
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.
