Cicada killers are large wasps often mistaken for more aggressive insects due to their size. These solitary digger wasps are known for preying on cicadas. Female cicada killers build individual nests in the ground. They spend their summers hunting from late June or early July until September or October.
Do Cicada Killers Sting Humans
Female cicada killers possess a stinger, primarily used to paralyze cicadas for their offspring. They are generally not aggressive towards humans and rarely sting unless severely provoked, such as being stepped on, grasped, or caught in clothing. Male cicada killers do not have a stinger and are incapable of stinging. They may exhibit territorial behavior, flying aggressively, but this poses no threat to humans.
Understanding a Cicada Killer Sting
If a sting from a female cicada killer occurs, it typically results in localized pain, swelling, and redness. The sensation is often described as a minor pinprick, similar to a common wasp sting. The venom is primarily designed to paralyze cicadas, not to cause significant harm to larger animals. Basic first aid involves cleaning the affected area and applying a cold compress to reduce swelling and discomfort. Medical attention is rarely necessary unless an individual experiences a severe allergic reaction, such as difficulty breathing or widespread swelling.
Identifying Cicada Killers
Cicada killers are among the largest wasps in North America, with females reaching nearly 2 inches and males around 1.5 inches. Their bodies are robust, black, and marked with distinctive yellow or orange bands on the abdomen. They have reddish-brown heads and thoraxes, with amber-colored or brownish wings. These solitary wasps create burrows in well-drained, often sandy or loose soil, identifiable by a U-shaped mound of excavated dirt. Unlike social wasps like yellow jackets or hornets, cicada killers operate individually.
Living Alongside Cicada Killers
Cicada killers are beneficial insects because they help control populations of annual cicadas, which can sometimes damage trees. Their presence in a yard often indicates loose, sandy soil and a nearby cicada population. To minimize interactions, avoid walking barefoot in active areas and refrain from disturbing their burrows. Maintaining a healthy, dense lawn with consistent watering can also deter them, as they prefer to nest in sparse, dry soil. If their numbers become overwhelming or burrows cause significant disruption, professional pest control can be considered.
