According to National Geographic – ” Cicadas are benign to humans under normal circumstances and do not bite or sting in a true sense, but may mistake a person’s arm or other part of their body for a tree or plant limb and attempt to feed. Males produce this species-specific noise with vibrating membranes on their abdomens. The sounds vary widely and some species are more musical than others. Though cicada noises may sound alike to humans, the insects use different calls to express alarm or attract mates.” I personally love to hear them sing in the evening while sitting in our back yard.
Most species of Cicadas are called annuals because, although individuals have multi-year life cycles, some adults appear every year. Our 17 year wait is over and here they come again. “In places where they’re going to be present, it’s going to be spectacular. Michael Raupp, a professor of Entomology at the University of Maryland, says, “There could be as many as one billion cicadas emerging per square mile,”
Cicadas can cause damage to several cultivated crops, shrubs, and trees, mainly in the form of scarring left on tree branches while the females lay their eggs deep in branches. Cicada control can be established using a dust called Delta Dust and a shot-gun duster applicators for large areas and or a hand duster dust applicator for smaller areas.
