Chafer grubs cause extensive damage by feeding on plant roots in turf. The secondary damage is just as destructive when birds, badgers, foxes, moles and other small mammals rip up the already weakened turf in search of their protein rich larvae. Tell-tale signs of infestation include birds pecking at the grass, poor grass growth, the appearance of yellow patches and the ability to pull the turf up because there is little or no root growth. Nemasys G is made up of the beneficial nematode: Heterorhabditis bacteriophora, which able to neutralise chafer grubs when they are just larvae.
