Vine weevils are a serious threat to a wide range of plants, particularly those in pots, containers, and cultivated in both ornamental and fruit-growing settings. While adult weevils feed on leaves during the warmer months, their larvae pose the greatest danger. These white, legless grubs with brown heads burrow into the soil, feeding on plant roots, which leads to weakening, wilting, and often plant death—especially in autumn and winter. Potted plants, whether grown outdoors or under cover, are especially vulnerable. Vine weevils are one of the most destructive garden pests. Adult Vine weevils are nocturnal and can travel quite long distances to infest your plants. It can also be effectively used against Sciarid fly (fungal knats), Carrot Root fly and Cabbage root fly .

How These Nematodes Work

Our beneficial nematodes actively seek out and infect vine weevil larvae in the soil. Once inside the larvae, they release symbiotic bacteria that cause fatal infections, halting the pest’s lifecycle. These nematodes specifically target the larvae, reducing vine weevil populations before they mature into adults. Suitable for use in containers and garden or open-field cultivation.
