about the product

Weevil larvae in the soil look like white grubs and cause the most damage by eating the roots, reducing the ability to take up water and nutrients. Often the first sign of vine weevil damage is a wilting plant. Black weevil adults also eat the leaves and create notches on the edges.

Product contains living nematodes and should be applied as soon as possible. Fresh is best!

How to apply vine weevil nematodes:

1. Store package in fridge (4°C) until use. Do not freeze.
2. If applying with a watering, mix contents of pack in a bucket containing 1.5 L of water.
Add one third of the bucket contents to a watering can and fill the watering can with additional water.
3. Apply to one third of the area to be treated through a coarse rose. Then repeat the above two steps until all product is used.
4. If applying with a hose end sprayer, mix with water and add to the applicator. Apply evenly over area to be treated.
5. After applying nematodes, additional water should be applied to the treated area to wash nematodes into the soil.
6. Use the entire pack in one go. Do not store opened packs or made up solutions.
Soil should be kept moist for 2 weeks after application to help the nematodes work.

When soil temperatures are above 12C, normally April to October.

Traditionally adults emerge from May to July when a female has the potential to lay up to 1,500 eggs. After hatching the larvae pupate the following spring before adults emerge again from May. However, a combination of milder winters and increased use of protected growing has meant this lifecycle is no longer as structured and larvae may be present at any time during the year.

How does vine weevil killer work?

Vine weevil nematodes hunt down the vine weevil larvae in the soil, burrow inside and kill them. They then reproduce inside the larvae, producing more nematodes to hunt down more vine weevil until none are left.
