Product Information

Nemasys Vine Weevil Killer is the simple solution to control vine weevil.
Apply to pots and open ground March to May and August to November. This is when the vine weevil larvae are present and the soil is above 5ºC (40ºF). If applying under cover the pest’s lifecycle is broken and Nemasys Vine Weevil Killer can be applied at any time, as long as the soil is above 5ºC (40ºF). Apply directly to the soil around the roots which is where the larvae will be feeding.
To keep a minor problem at bay, one autumn treatment should be adequate. However, for a serious infestation, treat in the spring and again in the autumn. When treating pots take care that the pots are not allowed to dry out.
The nematodes (Steinernema kraussei), seek out the vine weevil larvae and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey. Nemasys Vine Weevil Killer will kill larvae present in the area and protect against further larvae damage for up to four weeks.

What damage do they do and how do I recognise it?:

The adults eat plants in summer and autumn, leaving distinctive crescent-shaped notches on leaves. Finding and destroying the adults is difficult as they are nocturnal, quick moving and play dead once disturbed.

The vine weevil grub (larvae) is far more of a danger to plants than the adults. The young larvae feed on plant root systems, initially on small fine outer roots, but progressively attacking the more important main roots as they grow bigger.

The first signs of attack by the larvae are usually when the plant starts to wilt. This is too late to save it! It is therefore more important to kill the larvae than the adults.

Primulas, fuchsias, begonias, most evergreen plants and all plants in pots are particularly at risk. They also attack strawberry and raspberry plants.                                                                      

This pack contains 6 million nematodes which is sufficient for treating 12m2
