Vine Weevil Killer Nematodes

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 soil is not left 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 causes blood poisoning stopping the larvae from feeding, quickly killing it. The nematodes then 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.
