Vine Weevil

Vine weevils are beetles

  • They have a long thin snout and are approximately 8-14 mm (¼ to ½ inches) in length. They are dull black with patches of tiny yellow bristles. They cannot fly but can walk 3 miles in a year.
  • All adults are female and lay hundreds of white eggs, approximately 0.8 mm in diameter and round. They rapidly turn brown as they mature.
  • The eggs are often confused with slow release fertiliser pellets, such as Osmocote, which are found in most common compost mixes. The Osmocote pellets are 2 mm in diameter, release liquid fertiliser when squashed and range in colour from yellow to dark brown

Vine weevils are beetles

  • The eggs hatch in to larvae that are ‘C’ shaped and legless, with a small head. The larvae feed and grow throughout late summer and autumn. During winter their growth slows as temperatures decrease and feeding activity also decreases. As the temperature rises in spring, larvae activity starts to increase again causing more and more root damage.
  • Eventually the larvae stop feeding and pupate (during May) and quickly hatch into adults; and so the cycle continues.
  • Outdoors, the adults emerge in early summer (June) and lay their eggs immediately, starting the year long lifecycle again.
  • Indoors, vine weevil will breed all year round resulting in the pest being present at all stages at any one time.
Adult Vine Weevil

Vine Weevils Can Cause a lot of Damage

  • The adults eat plants in summer and autumn, leaving distinctive crescent-shaped notches on leaves. Finding and destroying the adults is difficult as they are nocturnal, quick moving and play dead once disturbed.
  • The vine weevil grub (larvae) is far more of a danger to plants than the adults. The young larvae feed on plant root systems, initially on small fine outer roots, but progressively attacking the more important main roots as they grow bigger.
  • The first signs of attack by the larvae are usually when the plant starts to wilt but by then it is too late to save it! It is therefore more important to kill the larvae than the adults.
