I know, the name sounds scary and this insect looks pretty intimidating, but the truth is that cicada killer wasps are just another beneficial insect you are bound to run across at this time of year … and you can’t miss them. They are very large, ranging in size from 1 to 2 inches. Their long bodies are black and have distinct yellow markings on the lower part.

Dr. Nancy Hinkle, University of Georgia Cooperative Extension Entomology specialist says, “Although intimidating in appearance, these wasps are not something we humans have to worry about. Cicadas, on the other hand, should be very afraid. Cicada killer wasp adults feed on nectar but use paralyzed cicadas to feed their young.”

Since cicadas can do damage to shrubs and trees in your landscape, these insects are actually beneficial to you. They prey on a damaging insect and do not harm people. There is generally no need to control them, as they do not pose a hazard to people. 

But what about stings, you ask? Females have a stinger, which they use to paralyze the cicadas they provide to their offspring, but the females are so focused on this task that they rarely pose a hazard to humans and are not likely to sting. 

The males may act aggressively in their quest to protect the female and offspring. However, male cicada killer wasps do not have a stinger, so they are not capable of stinging. They will behave in an intimidating way to try to keep potential predators away from the females as they go about their cicada hunting. Those behaviors are all for show.
