Full Description

Adult Vine WeevilAdult 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 GrubVine 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.

Control vine weevils naturally by applying Nemasys® Vine Weevil Killer, which unlike chemical controls, kills the vine weevil grubs BEFORE they attack the plants and is so safe you can use on pot plants (both in the greenhouse and conservatory), container plants outside, and anywhere in the garden. It also SAFE to use on food crops such as strawberries and herbs! Nemasys® Vine Weevil Killer is safe to you, your children, pets and wildlife. Nemasys® Large Pack treats 100 sqm or 500 x 2L pots. For pot application, measure 10% of the pot volume and apply an equivalent amount of nematode solution i.e for a 10 litre pot apply 1 litre of solution. Apply Nemasys® Vine Weevil Killer as follows :-

  • Treat grubs discovered UNDERGLASS at anytime of year. Available all year round.
  • Treat grubs discovered OUTDOORS as long as the soil temp is 5c i.e. normally between March and October.

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 Fine as Rain Rose no.14) or use a NemaCan Watering Can, or use a EasyNem Applicator / Hose-end Feeder for larger areas. 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.

N.B. Need a Coarse Rose, NemaCan Watering Can, EasyNem Applicator or Hose-end Feeder  – Add one to your basket and save £1.00 off a Coarse Rose OR save £2.00 off a EasyNem Applicator, Hose-end Feeder or NemaCan when bought with your nematodes (savings applied at the checkout).

    I have been buying Vine Weevil Nematodes for a good few years now and they work. Last year I bought Nematodes for scale insects for the first time. Although I failed to follow the instructions fully, this spring is the first year the climber has been almost clear of insects, looks very green and healthy. Another product I will be buying regularly, (and using properly!) Reliable deliveries. Good products.

    I ordered Nemasys Vine Weevil Killer, the package arrived promptly even though it was a Bank Holiday weekend. I put the package in the fridge until I was ready. No problems with vine weevils since. So I can only assume it’s worked. Would recommend this company.”

    I have used Green Gardener several times for Vine Weevil nematodes and spoken to their team on the phone for advice as well. They have always been knowledgeable and very helpful. Delivery has always been on time and the product selection on their website is terrific. Highly recommended!

    A spring application of vine weevil treatment rescued my potted fuschias and primulas and I have just given them an autumn top-up to eradicate any which may have arrived since. It’s an effective organic product which is easy to apply and a lot cheaper than replacing plants, not to mention avoiding the distress of finding a sickly plant and uncovering those nasty grubs!

    I purchase a bulk order from Green Gardener twice a year. They are always most helpful and efficient. I would highly recommend.

    Prompt delivery of Nematodes, well packed, clear instructions for application. Fingers crossed now! I did use the nematodes last year, Spring and Autumn and this Spring there are hardly any grubs to be found but I am not taking any chances and have applied the Nematodes again. Those Vine Weevils are sneaky little blighters and I am on to them!!

    Brilliant range of products at competitive prices, delivered quickly and i always appreciate the delivery being included! Never had a problem with any of my orders, products are great quality. I order a lot of the vine weevil nematodes and they are very effective.

    Nematodes from you to deal with vine weevil grubs have been useful over the years in dealing with what would otherwise here be a major pest in containers. The ladybird house was simple to put together, seems sturdy, and we hope will be a good addition to insect provision in the garden. Delivery time was good, & packaging sensible.
