Vine weevils love to over-winter plants in containers, especially if they have some nice fresh pansy leaves (and later, roots) to feed on. The semi-circular chunks missing from the edges of the leaves reveal their presence. However, they do not usually chew holes in the centre of the leaves.
A dose of 'Provado Vine Weevil Killer' (9g/litre thiacloprid, mixed at 30mls per litre of water) will protect containers until spring.Vine weevils (especially the grubs, which chew through the roots) are also a problem for primroses, often used in winter containers as a source of bright colours. 'Provado' protects these as well.
