Leather Jacket
Leather Jacket
These nematodes are designed for areas that are showing signs of infestation which is either leatherjackets within the soil or when crane flies are seen emerging from the soil therefore for optimum control we advise two applications of nematodes each year; the first treatment during spring, and the second during summer.
Leatherjackets are the larvae of Crane Flies, and cause damage to lawns, and other grassed areas, by feeding on grass roots which leads to the areas becoming yellow and the grass coverage patchy. Lawns will generally suffer secondary damage when animals such as badgers, or birds will attempt to feed on the larvae and will dig or peck areas of lawn in the process.

Product Description
Leatherjackets are the larvae of Crane Flies and cause damage to lawns, and other grassed areas, by feeding on grass roots which can lead to areas becoming yellow and the grass coverage patchy. Lawns will generally suffer secondary damage when animals such as badgers, or birds will attempt to feed on the larvae and will dig or peck areas of lawn in the process.
To protect your grassed areas, we recommend treatments being made from February through to May (to kill overwintering leatherjackets) and August to October (2 weeks after seeing adult crane flies emerge from the soil). Please be aware of the temperature during the earlier weeks; ensure the possibility of frosts have passed, and that the soil temperature is over 10oC.
• Storage of Nematodes
As the nematodes are supplied live, it is important that you use them as soon as possible, ideally when they arrive, but if not possible then unopened containers can be safely stored in a fridge (at or around 4oC) until you are able to use them. Do not allow the contents of packets to freeze. You should not store opened packets or mixed solutions.
• Required Conditions
These nematodes are designed for areas that are showing signs of infestation which is either leatherjackets in the soil (for the early treatment) or crane flies emerging from the soil (for the later treatment). Before applying we recommend raking / scarifying or spiking the area which will help the passage of the nematodes into the soil. The nematode solution should not be applied during hours of bright sunshine as the nematodes are UV sensitive. We recommend applying during the early morning or evening when the UV levels are lower, the temperature will have reduced, and the humidity level will be better suited. The area should be moist before application and kept in this state for two weeks after.
• Usage Instructions
o Empty contents of packet (25 million/50 square metres) into a bucket containing 2.5 litres of water and mix. Continue mixing until the solution is free of lumps. You have now made your nematode concentrate.
o Add this 2.5 litres to a further 5.5 litres of water, and continue to stir until all lumps are removed.
o This 8 litres of solution is now ready to apply.
o Use the full 8 litres, do not store the solution.
• Next Steps
For heavy infestations, it may be necessary to repeat the treatment process every two weeks during the summer season.

FAQs
IS IT EASY TO APPLY YOUR NEMATODES?
The nematodes are supplied as a powder so once mixed with water it is ready to use but you must ensure there aren't any lumps in the solution. As you will be applying the Leatherjacket Killer Nematodes at ground level you can apply with either a watering can or a sprayer. If using a sprayer we recommend removing any filters from with the hose or spray gun to minimise the chance of blockages.
CAN I STORE THE NEMATODES?
Nematodes should be used as soon as possible. Unopened packs can be safely stored in a fridge, until you are able to use them, but please apply the treatments as soon as you are able.
WHEN SHOULD I APPLY THE LEATHERJACKET KILLER NEMATODES?
Treatment is most suitable from February through to May, as the Leatherjackets overwinter in the soil, however we recommend not applying if frosts are due or if the soil temperature is below 10oC. You should only apply this treatment if there are signs of Leatherjackets within the soil. Secondary to this we advise a treatment during the summer months based on the presence of the adult crane flies. This treatment should be made 10-14 days after seeing the adult crane flies emerge from your soil and is generally between late August to October. These summer applications are the most effective as the soil is warmer which provides better conditions for the nematodes.
HOW DO I APPLY THE NEMATODES?
As the Leatherjacket Killer nematodes are applied to grassed areas we recommend the use of either a sprayer or a watering can. A sprayer will allow you to monitor the coverage and to target your spraying but, for some, a watering can is easier to use.
WHICH PACK SIZE SHOULD I HAVE?
Obviously you should select the pack that corresponds with the size of area that you are looking to treat however we recommend allowing a little more square meterage than you may actually have to give a little leeway when applying. You may also want to consider the possibility of a second application as if you have a heavy infestation then a repeat treatment may be required one week after the first.
