Vine Weevil Nematodes (12 sqm )

Vine weevil nematodes (Steinernema kraussei) target vine weevil larvae living in soil around plant roots. Each treatment introduces microscopic transparent worms that enter the larva and stop further damage before it begins. This natural approach helps manage infestations during active pest stages.

Vine Weevil Nematodes for Seasonal Use

Use vine weevil nematodes in late spring and early autumn when larvae are most active. Apply to pots and open ground from March to May and again from August to October. Autumn treatments are often more successful because the larvae are younger and have caused less harm to plants.

How Vine Weevil Nematodes Target Larvae

Once added to moist soil above 5ºC, the nematodes move through the soil and locate vine weevil larvae. They feed and reproduce inside the larvae, bringing this pest stage to an end. For high levels of infestation, a second application can improve results and break the pest life cycle.

Using Vine Weevil Nematodes in Pots and Beds

Apply directly to the soil around plant roots where larvae feed. When used under cover, nematodes can be applied at any time as long as the soil remains above 5ºC. For extra protection, band pots with insect barrier glue to help stop adult pests from climbing in and laying eggs.

Easy Application of Vine Weevil Nematodes

Each pack includes simple instructions and can be applied with a watering can or nematode applicator. Keep soil moist before and after application to support nematode activity. The pack usually has an expiry date of around two weeks.

Frequently Asked Questions

How long do vine weevil nematodes remain active in soil?

They remain active for several weeks as long as the soil stays moist and above 5ºC, allowing them to move and work effectively.

Can vine weevil nematodes be used with other plant feeds?

Yes, they can be used alongside most plant feeds provided the soil is kept moist during application.

Are vine weevil nematodes safe for pets?

Yes, they are naturally present in soil and pose no risk to pets, wildlife, or people.

Can vine weevil nematodes be used on young plants?

Yes, they are suitable for young plants as they only target vine weevil larvae in the soil, not plant roots or shoots.

How soon can plants be watered after applying vine weevil nematodes?

You can water lightly after application to maintain moist conditions, which helps the nematodes move through the soil.

Do vine weevil nematodes need special storage?

Store in a refrigerator and use before the expiry date to ensure they remain active.
