Chafer Grubs - Spotting the adult chafer beetles will help you to identify the pest responsible for the damage, BUT always inspect the lawn for the grubs to be sure. Chafer Grubs are creamy coloured, approx 1.5 cm in length, have distinctive legs and will be found in the grass roots. They are often mistaken for vine weevils - but vine weevil tend to be smaller and do not have legs. Like leatherjackets, chafer grubs attack the grass roots causing identical symptoms, but chafers are larger and creamy coloured, making them easy to identify. Sampling your lawn to identify the pest - Inspect discoloured areas of lawn by cutting a 6" X 6" section of turf on three sides and peeling back the sod. Examine the upper 2 inches of roots for white grubs. Shake the sample or probe through the soil with knife or screwdriver to dislodge the grubs. As the grubs will not be distributed evenly, examine other parts of the lawn to find out the extent of the infection. 

The Garden Chafer Beetle emerges in May/June from the lawn and mate before laying eggs. These eggs hatch to produced chafer grubs. The eggs are often laid in the same place each year so the problem gets progressively worse. The Chafer Grubs feed on grass roots from July until late Autumn before burrowing deep into the ground to pupate. They are a source of food for large birds-crows and woodpeckers as well as foxes and badgers. These may do more harm to your lawn by ripping it up to get at the grubs. The Chafer Grubs then lay dormant during the winter deep in the ground before moving to the surface the following spring to emerge as beetles in May / June and starting the process again. As only the newly hatched grubs are susceptible to nematodes, there is only one opportunity a year i.e. August/early September to kill them when the grubs are newly hatched and near the surface.

Nemasys® Chafer Grub Killer - Control chafer grubs naturally by applying Nemasys® Chafer Grub Killer, which contains Heterorhabditis megidis nematodes that kill chafer grubs, but are harmless to children, wildlife and pets and the lawn may be used immediately after application. 

Nemasys® Chafer Grub Killer - Nemasys® Chafer Grub Killer should be applied to the lawn in August when the grubs are close to the surface and active.
