Adult vine weevils feed on plant foliage during summer and autumn, taking "U" shaped notches from the edge of the leaf. Adults are about 1cm long, brownish black with drab yellow spots on their backs. They are nocturnal and unable to fly, but being quick moving if disturbed are difficult to spot. They are fond of rhododendrons, camellias and azaleas as well as herbaceous plants. They only munch the edge of the leaf, which is unsightly, but it won't seriously harm the plant, unless there are lots of adults, but it's a good indication of vine weevil activity, so check for the more destructive grubs.
Vine weevil grubs are the real problem, attacking the roots of plants from late summer until the following spring. The grubs over-winter in the roots and emerge as adults in late spring / summer. These adults lay eggs in the rootballs of plants. The eggs hatch and feed before over-wintering and then the whole process starts again.Vine weevil grubs grow to about 1cm and are creamy coloured and crescent shaped with an orange head. Affected plants will wilt even though the soil/compost is moist and as more of the roots are destroyed the plant will eventually topple over.

Nemasys® contains the natural nematode, Steinernema Kraussei, which is effective at controlling vine weevil grubs. It comes as a powder,which is easy to use - just mix with water and apply like a liquid feed to the soil around the roots. Once applied, the nematodes seek out the vine weevil grubs and invade them. They multiply inside the grub turning it brown and papery before it disintegrates.The nematodes are then released back into the soil to get rid of more grubs. Easy!
How to apply? - Simply mix the harmless powder with water and apply to the soil around the plant roots with a watering can or a hose-end feeder. Use the whole pack before the expiry date which is marked on the inside of the pack and will be at least a couple of weeks. Apply to the rootball of the plants to increase the chances of vine weevil grubs coming into contact with the nematodes.
