Cicada Killer Wasps


Understanding Cicada Killer Wasps: The Giants of the Wasp World


If you’ve noticed large, intimidating wasps buzzing around your yard, there’s a good chance you’ve encountered cicada killer wasps. Though their appearance may be alarming, these wasps are often misunderstood. As part of our ongoing series on garden and yard pests, we aim to shed some light on cicada killer wasps—what they are, why they’re actually beneficial, and what to do if they become a problem in your outdoor spaces.


What Are Cicada Killer Wasps?

Cicada killer wasps (Sphecius species) are large, solitary wasps native to the United States. Adult wasps are around 1.5 inches in length, with a black body covered in yellow markings. Unlike social wasps like yellowjackets, cicada killers are generally non-aggressive and are not interested in your picnic food or sugary beverages.


The Role of Cicada Killer Wasps in the Ecosystem

Cicada killers play a critical role in regulating cicada populations. Female wasps hunt for cicadas, paralyze them with a sting, and then transport them back to their burrows to serve as a food source for their larvae. While the idea of this may sound menacing, it is part of a natural ecosystem balance. By controlling cicada numbers, these wasps indirectly protect trees and plants, which cicadas damage by laying eggs in the branches and consuming sap.



  1. They Are Aggressive

Contrary to common belief, cicada killer wasps are generally not aggressive towards humans. The males don’t have stingers, and although females do, they are usually not interested in humans unless directly threatened.


  1. They Are a Threat to Bees

Cicada killers specialize in hunting cicadas, not bees or other pollinators. Your garden’s bee population is generally safe from these large wasps.


  1. They Build Nests Like Other Wasps

Cicada killers are solitary wasps. They dig individual burrows rather than building communal nests. These burrows are usually constructed in well-drained, sandy soil.


When Do They Become a Problem?

Although they play a beneficial role in the ecosystem, cicada killer wasps can become a nuisance in some cases. Their burrowing can disrupt lawns and gardens, and some people are simply unnerved by their large size and presence.


Managing Cicada Killer Wasps

If you feel that cicada killer wasps have become a problem in your outdoor space, here are some steps you can take:


  1. Natural Deterrents

Changing the soil conditions to make it less suitable for burrowing can be an effective way to deter these wasps. Adding mulch or moisture can make your yard less attractive to them.
