What are leatherjackets?

Leatherjackets are the larvae of the crane fly. Or, as we better know them: daddy long legs. During the autumn months one female crane fly can lay up to 300 eggs in your lawn. Once hatched, the larvae wreak havoc in two ways: firstly, by feeding on grass roots which results in dead patches of lawn; and secondly, by causing their natural predators such as foxes, badgers, birds, and moles to dig up your lawn looking for food.

How do I spot leatherjackets?

The first obvious symptom of leatherjackets is yellow and brown patches of dead grass, but this is also a symptom of many other lawn issues. By digging into a small section of turf you will be able to see the leatherjackets in the affected layers of the soil. 

You will also spot leatherjackets on the surface of your lawn during heavy rainfall, as the water forces them above ground.
