Cicadas produce exceptionally loud songs by vibrating drum like tymbals rapidly. They are generally 2-3 cm long and have large, clear wings with many wing veins. Their eyes are large, reddish or black and set apart on each side of the head. Cicadas don’t cause damage by chewing leaves, but do create damage as they lay eggs. Adults live for 2 to 7 weeks during which time they mate, lay eggs and die. One type of cicadas emerges from the soil every year, while the periodical, emerge at either a 13 or 17-year interval. Periodical cicadas are so predictable that charts can forecast when they will appear. Some effective methods of cicada treatment include: picking adults and nymphs off plants by hand, knocking cicadas off plants by spraying water, wrapping tree trunks and large bushes with foil or sticky bands and protecting young or valuable plants by covering them with netting.
