Identifying Leatherjacket Lawn Damage
Lawns develop patches where the grasss turns yellowish brown and often dies. Lift the turf affected to see if you have leatherjackets in the soil
Birds will search for leatherjackets in turf and leave small round holes in the lawn where they have inserted their beaks.
In flower beds or vegetable plots, seedlings and small plants can be killed when the stems are damaged at soil level
