Grass growth slows and yellow patches appear as the leatherjackets get munching. As a result grass is easily pulled up, with little or no root growth.
In August you might see clouds of daddy-long-legs emerging from lawns in the early morning and this is a sure sign of leatherjacket infestation.
Starlings peck at the grass in an attempt to eat the grubs.
Wildlife, such as foxes and badgers, can also create a lot of damage as they dig up your lawn in search of grubs for food.
Use Nemasys Leatherjacket Nematodes to deal with a leatherjacket infestation, without any of the precautions associated with chemical use, such as excluding children and pets from treated areas.
Apply when the young leatherjackets are active in the soil, this is typically late August through to the end of October.
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.
Apply to moist lawns when the soil temperature is above 12ºC
