How can I prevent grubs eating the fruit on my raspberries?

The raspberry beetle is a common pest of raspberry plants but can also attack loganberries and other hybrid berries.

In June and July the female beetle lays its eggs on the stamen and other parts of the flower. The larvae which are a creamy - white with brown markings hatch about two weeks later and start feeding by tunnelling into the developing fruit. After about a month the larvae make their way to the soil where they pupate. The adult beetles emerge during April and May. They then fly on to apples, hawthorn or other flowers where they feed on the flowers, stamen and pollen before moving onto raspberries as the fruits start to open.

The raspberry beetle can be controlled at flowering time by spraying with Bayer's Ultimate Fruit and Vegetable Bug Killer. As with all chemicals follow the manufacturer's recommendations.
