Fall cankerworms have caused significant damage to Wasatch Front trees and oak-brush for the past three or four years, but residents can fight back.

The Utah Division of Forestry, Fire and State Lands will conduct a one-hour workshop that covers the life cycle of the insects, types of damage they can cause and options to deal with the pests.The workshop will start at 6:30 p.m. April 15 in the conference room of Bountiful City Hall, 790 S. 100 East.
