To help reduce cicada damage, it is recommended to homeowners that they not prune trees this spring. Instead, damaged twigs may be pruned out later in the summer, after the cicada invasion has run its course. In affected areas of the state, most tree damage can be avoided by delaying new plantings of woody ornamentals and trees until fall or the following spring.
Brood 14 is expected to emerge in Champaign, Greene, Warren, Clinton and Butler counties within the Miami Valley. This brood of Cicadas will appear in 12 states.
For more information regarding insecticide recommendations, homeowners should contact their local extension agent or entomologist, being certain to follow all insecticide label directions carefully.
