Weevils are a group of beetles that are distinguished by long snouts and legless larvae. The adults and larvae can be pests in the garden; the adults eating notches in the edges of leaves and the larvae/grubs eating plant roots.
Pest weevils in the garden include Fuller’s rose weevil, black vine weevil, vegetable weevil, garden weevil, white fringed weevil and Argentine stem weevil. Although each weevil species has a favoured plant to feed on they will attack a variety of crops or plants.
Weevils are commonly found attacking:
Fuller’s rose weevil – roses, citrus, strawberry, potato and grape.
Black vine weevil – greenhouse plants, strawberry, blackcurrant, grape and rhododendron.
Vegetable weevil – brassicas, carrot, parsnip, lettuce, beet, spinach as well as citrus, grape, gerbera and mallow.
Garden weevil – agapanthus, aster, chrysanthemum, crocus, gerbera, grape, succulents and many others.
White fringed weevil – potato, kumera, lettuce, tomato, rnunculus and brassicas.
Argentine stem weevil – ryegrass and other grasses in lawns and pasture.
In all cases the larvae eat the roots and the adults eat foliage. It’s always better to prevent your plants from being infected with diseases rather than trying to cure them. We at NorthWest Pest Patrol have the knowledge and technology to resolve your weevil related problems.
