Strawberry blossom weevil: how to recognise and treat it
Pest

Symptoms
- Flower buds hang on a partly severed stalk, wither and drop without opening; the female lays an egg in the bud and then gnaws the stalk.
- A small, curved, creamy-white larva with a brown head lives inside the withered bud.
- Dull black weevils 2–4 mm long with fine grey hairs and a long snout on buds and flowers in spring.
- Small round holes in petals and in young folded leaves.
- Damage is patchy and worst near hedges and woodland; in a heavy attack most flowers can be lost.
Organic treatment
- Pick up and destroy severed buds, on the plant and on the ground — the larvae develop inside them.
- Brush or shake the plants over a light-coloured bowl to catch and destroy the adult weevils.
- Spare spiders, ladybirds and birds; small parasitic wasps also attack the larvae.
Chemical treatment
- Pyrethrins on the adult weevils before flowering, when the first severed buds appear; good spray cover is needed. Check the product is approved for strawberries in your country and follow the label dose and pre-harvest interval.
Reference information, not a guarantee. Read and follow the label of any product: dose, safety and the days to wait before harvest.
Prevention
- From the start of flower-stalk growth in spring, check the plants weekly for severed buds and adult weevils.
- Inspect first the edges of the bed next to hedges or woodland, where the adults overwinter in the leaf litter.
- Early varieties and young plants suffer most; everbearing varieties usually make up for lost buds later in the season.
