![]() It sounds like a joke but is a very effective method of control! Just don’t get tennis elbow. Other times, a more physical approach to removal can involved using a tennis racket to kill them. Sometimes, simply setting up a sprinkler and regularly running it in the area can make it wet enough that the wasps are discouraged away. They can be scary for people and annoying as they fly around. UK entomologists routinely receive reports of them digging in between parts of retaining walls and also appearing on open playgrounds. They like areas with loose, dry, light textured soils in the open sun. However, cicada killer populations can build in a local area over time. Because of this, it is rare that cicada killer wasps need to be managed. Because they are solitary, they lack the defensive mindset that leads to stinging incidents occurring with bees and hornets. They can sting and it has happened before, but it is rare. (Photo: Jody Green, University of Nebraska).Ĭicada killers are not considered a stinging hazard. While cicada killer wasps can be annoying and a little scary, they mean humans and pets no harm. (Photos: Northern giant hornet photo–Washington State Department of Agriculture Cicada killer–University of Florida).įigure 3: The face of death for a cicada. Note differences in the size of the head, coloration, and patterns on the abdomen. Figure 2: A comparison of Northern giant hornets (on the left) and cicada killers (on the right). The cicada killer is darker overall and has distinct patterns rather than bands on their abdomen. The Northern giant hornet’s head is much larger and broader than the cicada killer they also have a yellow-orange coloration for their head and their abdomen is banded black and yellow-orange. The two species also look different upon closer inspection. This means they have a much higher propensity to sting. For example, whereas cicada killers are solitary wasps, the Northern giant hornet is a social insect. There are many differences between the species. Confusion Over Identityīecause of their size, there have been many inquiries about cicada killers being the Northern giant hornet (scientific name Vespa mandarina, but most famously known as the “murder hornet” in popular media). The height of cicada killer season is late July and early August. In the burrow, a chamber with a female egg may get 2 to 3 cicada to eat while male eggs get 1 cicada. ![]() When they sting a cicada, they either fly it back to the nest, drag it, or do a series of aimed “jumps” where they carry it to a tree or bush and jump/glide to get it home. An individual female may excavate about 100 cubic inches of soil to make a home for her young. ![]() As mentioned before though, they don’t have a true stinger, so they are all bark and no bite.Ĭicada killer burrows can be quite long underground. Females tend to disregard people, but males may attempt to deter humans from approaching burrow areas by hovering near your face. ![]() Males can be found hovering near areas of female activity. Solitary females construct their burrow in the soil and hunt for cicadas. These are not social wasps they don’t have a colony with a queen and workers like yellowjackets or European hornets. (Photo: Jessica Louque, Smithers Viscient, ) They are up to 2 inches long and both males and females have dark orange heads/thoraxes with black and yellow abdomens. Females also have a stinger at the tip of their abdomen, while males have a pseudostinger (it isn’t hooked to a venom sac).įigure 1: Female cicada killers can be found flying or burrowing. The females have spurs on their back legs, which will help them with digging tunnels used as a nest for their larvae. Both sexes have orange-colored heads and thoraxes with black abdomens that have yellow designs on them. It’s a bug eat bug world out there! Cicada Killer BasicsĪdult cicada killer females are up to 2 inches in length, while males are a little smaller, usually around 1.5 inches long. After the eggs hatch, the immature wasps will slowly devour the cicada alive. They have to be big because they hunt those large cicadas, sting, and paralyze them, and then drag their body to a hole in the ground where the wasp will lay her eggs on the cicada. This parasitoid wasp is one of the largest wasp species in Kentucky. ![]() Depending on your opinion of their singing talents, you might be delighted or horrified to learn of the cicada killer wasp. As we head into the latter end of summer, the trees are alive with the sound of insect music thanks to annual cicadas. ![]()
