Cicada Killers, also known as ground digger wasps, are a common wasp species encountered by homeowners, especially those living in the warmer parts of the country. Cicada Killers can be alarming to see at first glance because they look like an over-sized bee flying around in yards or gardens. Due to their size, Cicada Killers are often mistaken for the European Hornet and, most recently in the U.S., the Asian Giant Hornet.

Inspection
After properly identifying cicada killers on your property, you can proceed with inspection. During this step, you are determining where cicada killers are found in your yard and conditions attracting them to your home.
Where To Inspect
Cicada Killers like to hang around in backyards, flower beds and grassy areas, which is why homeowners frequently run into them.
However, the presence of Cicada Killers may not indicate that a nest is in the area. Cicada Killers like to burrow their nests in the ground, especially in sandy soils.
What To Look For
Look for Cicada Killer Wasp themselves or Cicada Killer Wasp nests. It may be helpful to observe their flight tendencies.
If you find one, follow it closely and they may lead you to where their nest is if it is set up in your yard.
Cicada killer nests are tunnels that are dug in the ground. They will appear as a hill of dirt with a 1 to 1.5 inch diameter hole in the middle that they use as their entrance. Once you have identified their nests you're ready for treatment.
Treatment
If you are up to the job, it’s best to gear up and have protective clothing and gear on to keep you safe from potential harm.
To get rid of Cicada Killers Wasps, figuring out where they are nesting and treat the hole directly with Sylo Insecticide.
Remember to first read all product labels and follow the application instructions on these labels, and stay safe by wearing personal protective equipment.
Step 1 - Direct Nest Treatment With Sylo Insecticide
Sylo Insecticide is a synthetic pyrethroid insecticide that contains the active ingredient Cypermethrin and serves as a good contact insecticide that will effectively kill Cicada Killers. This chemical is a residual insecticide and should be used if you have located the nest so you can spray directly inside the tunnels. The chemical traces allow the larvae to get killed as well.
You will use a 0.25% emulsion (1.3 fl. oz. per gallon) of Sylo Insecticide in a sprayer with a gallon of water to spot treat the nests you have located, making sure to apply to all of them in one visit. Locating the nest and treating it directly is vital to successfully controlling the Cicada Killers as the product will not work as a spot treatment if you can't find the nest.
To treat Cicada Killer Wasp burrows, place your sprayer on a pinstream setting and then spray at a low-pressure. Spray a small area of the solution around the entrance of the burrow and then apply the Sylo Insecticide directly into the nest. Cicada burrows can run up to 5 feet in length and 15 inches deep underground, so spray the hole thoroughly.
You should apply the insecticide preferably in the evening time as this is when it is most likely that all the adult Cicada Killer Wasps are inside. Proceed with caution and have on protective long-sleeve clothing as there is a chance Cicada Killers may come out and try to sting you.
Prevention
After successfully getting rid of Cicada Killer Wasps from your yard, you want to make sure they don't make a return. Chances are, Cicada Killers may have laid eggs before succumbing to insecticides and soon the eggs will hatch, bringing on a new generation of Cicada Killers creating problems. Also there may be Cicada Killer Wasp pheromones left behind that may draw other Cicada Killers to your property.
Some cultural practices you can implement to reduce Cicada Killer Wasp populations and discourage them from your property is to:
- Properly maintain your lawn to promote thick, dense turf.
- Water your lawn deeply with 1 to 1.5 inches of water.
- Put out mulch of at least 3 inches under shrubbery and in your garden or flowerbeds.
- You can also try mowing the lawn on a higher setting of 3 to 4 inches as tall vegetation is unappealing to Cicada Killers and will make them less likely to dig a nesting tunnel in your yard.
- If visible tunnels pop up, apply Sylo Insecticide directly to these tunnels as soon as they are spotted.
