What Are Vine Weevils?

Vine weevils are one of the most destructive garden pests. Adult Vine weevils are nocturnal and can travel quite long distances to infest your plants. All adult Vine weevils are females and can lay high numbers of eggs that develop into Vine weevil larvae. It is these larvae that can cause the most devastating damage to a wide range of plants as they feed on plant roots. The larvae will kill plants by continued feeding on the roots, and plants may appear as if they need watering when they are infested. Adult Vine weevil will also feed on the leaves of plants and damage will show as notches, or half-moon shaped cuts on the edges of leaves. 

What Are Vine Weevil Killer Nematodes & How Can They Help?

Naturally and safely control your Vine weevil infestation with our Vine Weevil Killer Nematodes, which are deadly to the Vine weevil larvae but safe to humans and wildlife. Vine Weevil Killer contains Steinernema species nematodes, or Heterorhabditis bacteriophorain the summer months. These nematodes enter the larvae via a natural opening, like the mouth, and feed on the contents of the larvae. A natural bacterium is produced by the nematodes inside the larvae, which kills it. Infected larvae will be completely broken down by the nematodes. The nematodes also reproduce inside the larvae, releasing more nematodes into the surrounding area. 

When Should I Apply The Nematodes?

We advise applications of Vine Weevil Killer Nematodes between January and May, and again from August to October for outdoor applications. For indoor applications, where there is heating, Vine weevil larvae may be found all year round so treat when required.

Soil, or compost, temperatures should be above 8℃ for optimum application.

In cooler conditions, in the spring and late autumn, Vine Weevil Killer contains a nematode that is active at lower soil, or compost, temperatures. In the summer months Vine Weevil Killer is conversely supplied with a nematode suited to higher temperatures. 

How Many Nematodes Do I Need?

Vine Weevil Killer Nematodes are supplied in the following pack sizes:

- One pack of Vine Weevil Killer 5 million nematodes will treat up to 10m2

- One pack of Vine Weevil Killer 10 million nematodes will treat up to 20m2

- One pack of Vine Weevil Killer 25 million nematodes will treat up to 50m2

- One pack of Vine Weevil Killer 50 million Nematodes will make ten watering cans worth of solution to treat an area of up to 100m2

- One pack of Vine Weevil Killer 250 million Nematodes will treat an area of up to 500m2

- One pack of Vine Weevil Killer 500 million Nematodes will treat an area of up to 1000m2

What Conditions Do The Nematodes Require?

Choose a humid or wet day to apply your Vine Weevil Killer Nematodes. Nematodes are UV-sensitive and will not survive long when exposed to bright, sunny conditions. Apply the nematodes early in the morning or early in the evening in order to utilise the optimum humidity levels. Ensure the soil is moist at time of application.

How Do I Apply The Nematodes?

(The following instruction measurements apply to the 100m2 pack)

1. Open and empty the contents of your 50 million sachet of nematodes into a bucket or container of 5 litres of water and mix thoroughly to make a nematode concentrate solution.

2. Next, take 0.5 litres of nematode concentrate solution and add to an 8 litre watering can and fill with water (or use our specific nematode applicator, the Nema Super Sprayer, for optimum nematode application).

3. Water the diluted nematode solution into the infected area with each watering can covering an area of 10m2. 10 watering cans be made up from the 5 litres of nematode solution which can treat a total area of 100m2.

Ensure your soil area is moist for up to 2 weeks after application. This will help the nematodes enter the compost to search and find the Vine weevil larvae.

Full application instructions are provided on delivery.

Where Should I Apply The Nematodes?

These tiny microscopic nematodes can be watered into pots and containers. They can also be applied to raised beds, flower beds and borders.

Can I Store Nematodes?

You can store unopened nematode packs in a fridge but it is best to ensure you apply your nematodes as soon as possible for the best results.

They really work

This is the 3rd year I've used nematodes against vine weevil. It's only May but I had no damage last year and don't expect any this year. Far more effective than chemicals .
Previously, I lost plants in pots
Definitely recommend this product.

Result hooefully

I have only just today added the product to the hanging baskets so the proof in the pudding is that it dies the job of killing the vine weevils. Will be watching very carefully in the next 10 days or so if the application has been successful.
