Leatherjackets are the larval stage of the crane fly or daddy-long-legs, they are are about 2.5cm (1" long), greyish black in colour, legless and with no distinct head (see pictures above).
Also known as Tipula paludosa (European crane fly) or Tipula oleracea (Marsh Crane Fly).
Use Nemasys Leatherjacket Killer to deal with a leatherjacket infestation, without any of the precautions associated with harmful chemicals.
Nemasys Leatherjacket Killer is incredibly effective and is 100% safe for children, cats, dogs, other pets and wildlife.
When you start to see the adult daddy-long-legs in your garden (towards the end of August) you will know that in a few days they will be laying eggs. These will hatch quickly; therefore aim to apply two weeks after you see the adults.
This is when the young leatherjackets are active in the soil and is when they are most susceptible to the nematodes.
If you have discovered Leatherjackets (not daddy long legs) at any other time of year i.e. in the spring/summer then treat at double strength as the mature LeatherJackets are much harder to kill - you must treat in autumn as well.
Where a severe LeatherJacket infestation is present, multiple treatments over an extended period (spring and autumn) may be required.
The nematodes (Steinernema feltiae), seek out the leatherjackets and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest.
The nematodes then reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey.
Beneficial nematodes are living organisms, so they must be used before the expiry date (which is marked on the inside of the pack and will be around 2-3 weeks) and should be stored in the fridge until it is applied.
Prior to applying the nematodes:
To avoid desiccation of the nematodes:
Applying Nematodes with a hose end feeder:
To calculate your area measure the width and length of the area to be treated and multiply them by each other e.g. 5m x 10m = 50 sq.m
Leatherjacket Killer - Spring application must be made at double strength - therefore this pack treats 50 sq.m - even though the outer sleeve shows 100 sq.m.
