Fully-grown grubs burrow deeper into the soil to pupate, usually in late spring. Plants growing in the open ground are less likely to be damaged, although heavy infestations of grubs can occur on The adult beetles feed on the foliage of many herbaceous plants and shrubs, especially There are several other species of weevil closely related to vine weevil, the adults of which cause similar damage but are usually less problematic as larvae.Vine weevil is a widespread insect in Britain.

Controlling vine weevil grubs.
It is a pest of many garden plants. The adult weevil is matte black with fused wing covers, and is unable to fly. In a mild year, egg-laying could start in early summer.

The adult weevil is around between spring and autumn,so if you can get at them before winter it would help greatly. The main downside with using nematodes to control vine-weevil larvae outdoors, or in an unheated greenhouse, is that they are very sensitive to temperature. If you go out at night with a torch there’s a good chance you will see them feeding on the foliage. Adult weevils may be seen on the foliage at night; during the day they hide in dark places. They often lie in a sort of “C” shape, and look almost like a very fat short caterpillars.

The adult weevils eat leaves during spring and summer, but it is the grubs that can cause the most damage over autumn and winter when they feed on plant roots. Often the first signs of damage are only spotted when a plant completely wilts and dies. This makes August and September the most effective application period, though you can apply in April or May before the adult weevils emerge from their pupae if it is warm enough. (This sort of damage is likely to be caused by caterpillars or slugs.) These eggs are less than 1mm across, white at first, later turning brown. The female weevils lay their eggs in the compost or soil among host plants. They can be a particular problem in pot grown plants and adults seem particularly keen to lay their eggs in peat based compost. The most direct is to keep an eye open for the adults and destroy any that you find. Vine Weevil larvae are ugly-looking grubs which feast on plant roots, often completely severing them from the upper stems. Both the adult vine weevil and larvae cause damage.
Vine weevils have always been a serious pest of greenhouse plants, including grape vines, but commercial growers were able to keep them under control using Aldrin, a soil insecticide.
As a rule, this happens in August and September, though a lot depends on the weather during the previous winter and spring.
