The only leatherjacket lawn treatment available is to apply nematodes in the Autumn and Spring.
Once applied to the lawn, the nematodes will attack and infect the leatherjackets in the lawn.
A couple of leatherjacket lawn treatments may be necessary to control the initial infestation of leatherjackets followed by regular annual leatherjacket lawn treatment.
The number of eggs laid in the soil by the crane fly can be reduced by applying a chemical spray in August & September.
The photos above show a small lawn that underwent leatherjacket lawn treatment after being affected by leatherjackets in the lawn. The first photo, taken at the end of March, shows the lawn completely stripped by leatherjackets from eating the grass roots. The second photo was taken at the end of June after the following leatherjacket lawn treatment was carried out on the lawn in April:
- The lawn was spiked with 3" tines
- The lawn was sprayed with nematodes
- The lawn was topdressed with compost
- The lawn was overseeded with rye, fescue and bent mix
- The lawn was fertilised with high nitrogen and phosphate
