Pesticide control The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner.

They are based on plant extracts, plant oils or other safe compounds and have to be sprayed directly on the to the pest that you are trying to control. As such they will take more than one application over several days to remove all pests. And you can also control the adult beetles with nematodes, using Nematop Adult Vine Weevil Traps. Vine weevil eggs More serious is the damage can becaused by the soil-dwelling larvae, which are plump, white, legless grubs up to 10mm (about 3/8in)long with pale brown heads. These eat the roots of a wide range of plants andcan bore into tubers of cyclamen and begonia, and into stem bases of cacti and succulents. They can kill woody plants by gnawing away the outer tissues of the larger roots and stem bases. Most plant losses occur during September to March, when the grubs are becoming fully grown. Thoroughly rinse the watering can used after use and pour the washings over compost with ornamental plants in pots.

Pour the solution over the compost, at the recommended rate. A litre of solution treats 10 litres of compost.

Sprays that promise prolonged protection after spraying are dangerous to bees and other beneficial insects. The following pesticides (from by the Pesticide Action Network) contain neonicotinoids that are harmful to bees: Physical barriers on top of the soil or compost also work very well. Add a 2cm (0.75in) deep layer of sharp grit or gritty gravel on top of the compost or around the base of the plant to prevent the adults from laying eggs; the egg-laying structure is irritated by the scratchy feel. Weevils are a group of several families of beetles in thesuperfamily Curculionoidea, there are more than 500 species in the UK. All feed on plant material, mostly live plants but a few feed on dry seeds (grain weevils) or rotting wood. Most do not cause noticeable damage to garden plants and several species are uncommon.Vine weevil is classified in a subfamily of the known as the broad nosed weevils (Entiminae), so called because the of the broad snout (rostrum) these weevils have.
