Leatherjacket Control

Leatherjackets are the larval stage of the crane fly or daddy long legs and they can quickly devastate a lawn. Control leatherjackets naturally by treating with Nemasys® Leatherjacket Killer when they are discovered and the soil temperature is 10°c or apply when they are at their most destructive i.e. in the spring (April) and in the Autumn (Sept/Oct).
