Vine weevil larvae are one of the most damaging pests affecting container plants, ornamental borders, fruit crops and greenhouse collections. Because the larvae live beneath the soil surface and feed on plant roots, infestations often remain hidden until plants suddenly wilt or collapse.
Gardening Naturally Vine Weevil Nematodes provide a safe and effective biological solution for controlling vine weevil larvae in soil and compost. These beneficial nematodes actively search for larvae and stop them before they destroy plant roots.
Vine weevil larvae are the immature stage of the black vine weevil (Otiorhynchus sulcatus). These creamy white, C-shaped grubs live in soil or compost where they feed on plant roots, crowns and tubers. Larvae typically grow to around 5–10 mm long and can quickly kill vulnerable plants if left untreated.
Gardening Naturally Vine Weevil Nematodes contain Heterorhabditis bacteriophora, a beneficial microscopic organism used in biological pest control. Once applied to moist soil, the nematodes move through the root zone searching for vine weevil larvae.
After locating a host, they enter the pest and multiply, preventing further feeding and reducing the population.
