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).

  1. Nemasys Leatherjacket Killer 100 sqm

    Control leatherjackets naturally by treating with Nemasys® Leatherjacket Killer containing millions of natural nematodes. Apply the nematodes (Steinernema Feltiae) to the infected lawn as soon as the leatherjackets are discovered (and the soil temperature is 10c) or when the leatherjackets are active i.e. NOW. It is best to treat in the Sept/Oct when the leatherjackets are newly hatched as they are the most susceptible to the nematodes. You can treat at other times of the year i.e. in the spring/summer, but then you must treat at double strength as the mature leatherjackets are much harder to kill AND you must treat in Sept/Oct as well - see our DOUBLE DELIVERY. Nemasys® Leatherjacket Killer treats 100 sqm in the Autumn or 50 sqm when applied at double strength at any other time of year. Available NOW.

    N.B. Need a Haws Rose, Hose-end Feeder or Nematode Applicator - Add one to your basket and save £1.00 off a Haws Rose, save £2.00 off a Hose-end Feeder or save £3.50 off a Nematode Applicator when bought with your nematodes (savings applied at the checkout).
