Adult vine weevils feed on plant foliage taking distinctive "U" shaped notches from the edge of the leaf (pictured left). Adults are about 1cm long, brownish black with drab yellow spots on their backs (pictured right). They are nocturnal and unable to fly, but being quick moving they 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. N.B. Leaf damage is a sure sign of vine weevil activity, so check for the more destructive grubs in the roots of your plants.
Vine weevil grubs are the real problem, attacking the roots of plants. 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. Control vine weevils naturally by applying Nemasys® Vine Weevil Killer as soon as you discover grubs (and the soil temp is 5c) or when the grubs are at their most destructive i.e. in the Spring and Autumn.

Nemasys® Vine Weevil Killer contains the natural nematode, Steinernema Kraussei, which is effective at controlling vine weevil grubs, but is totally safe for children, pets and wildlife and can be used on edible crops too! It comes as a powder simply 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.
How is it sent? - Nemasys Vine Weevil Killer is a perishable, living product, so it is sent out fresh by Royal Mail 1st class post. Being a perishable, living product, it must be used before the expiry date (which is marked on the inside of the pack and will be at least 2 weeks) and it must be stored in the fridge until it is needed. Once opened, the contents do not keep, so it must be used in one day - do NOT store the made up solution or powder. 1 or 2 packs will go through your letterbox and should be popped in the fridge as soon as possible - they are fine on the doormat while you are at work.
How to apply? - Nemasys Vine Weevil Killer is easy to use. Simply mix the harmless powder with water & apply to the soil around the plant using a watering can fitted with a rose (we recommend the Haws Rose no.14) or use a hose-end feeder / Nematode Applicator. 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 root ball of each plant or soak pots to make sure the nematodes come into contact with any grubs present.

Great service at a good price
I have used Green Gardener products for a number of years. They supply a number of natural pest control options and I have tried several of them.
I have used nemaslug successfully for several years, also vine weevil control for adults and grubs. I have also tried encarsia in the greenhouse, adult ladybirds, larvae and lacewing larvae to control greenfly. All products that have worked well and benefitted the garden.
They provide a good and reliable service, particularly the two part delivery which ensures that you treat at the right time
- Vine Weevil Killer
I have bought vine weevil nematodes from Green Gardener for many years now and have had hardly any vine weevil grub attack, despite seeing adults in the garden regularly. Many of my plants have been in pots for the past 2 years because we moved house, but the twice-yearly application of nematodes have kept them clear, even the weevils' favourites, heucheras and ferns! Delivery is always prompt and customer service friendly. I would recommend them.
- Vine Weevil Killer
Easy access online. Good coverage of products available. Reasonable price, with good delivery service to your door. My lawn was infested with chafer grubs and a complete mess of brown and dead/dying patches. Now in mid-October and a proud owner of a full green lawn. May I also recommend Nemasys Biological vine weevil killer. Marvellous. Follow all the instructions for both products and you will not be disappointed.
