Cicada killers are solitary wasps measuring about two inches long. Their huge size makes them look scary but they really don't bother people. The males, although territorial, can't sting. The females are not aggressive and may only sting if stepped upon or crushed by the hand. Eastern Cicada killers resemble European hornets but are bigger and darker looking. Their coloring is black with reddish markings and light yellow stripes on their abdomens. Cicada killers will emerge from holes in the ground in June or July and live until September or October. These wasps got their name by killing and feeding on cicadas. Southeast Bee Removal does not deal with cicada killers.
