Capsanem Leatherjacket Killer is a leatherjacket treatment containing Steinernema carpocapsae; a species of native entomopathogenic nematode (microscopic worms) which controls infestations of crane fly larvae safely and effectively.

There are two application windows in the pests life cycle suitable for applying a leatherjacket treatment. The first window is during the late summer/autumn, from early August to the end of October, with the second window the following spring during March and April.

For best results apply Capsanem leatherjacket treatment to moist turf areas from early August to late October as this targets the pest early in its life cycle when it is more susceptible to control.

During the spring window the larvae will have grown to a stage where effective control of any type is significantly reduced. As a result it is important to note that the required application rate is higher for the spring window compared to the late summer into autumn window.

This means that a pro-active preventative approach to controlling crane fly larvae in turf areas is required. By treating with Capsanem Leatherjacket Killer in the August to the end of October application window, direct damage from the grubs and indirect damage from predators hunting for them in the following spring and summer is avoided.
