The problem: Spotted wing drosophila (SWD) is an increasing pest many fruits including: raspberries, cherries, strawberries, plums, currants, blueberries, grapes, gooseberries and blackberries. Adult flies are attracted to unripe fruit. Adults lay their eggs in green unripe fruit which can lead to fruit drop or in ripe fruit which then have fly larvae (maggots) present at harvest.

The product: Drosal® Pro traps are designed to trap adult SWD flies and not harm beneficial insects or bees. Product is suitable for use in all fruits where SWD is a problem.

  • Specifically designed to catch SWD.
  • Attracts and traps flies approaching from all directions.
  • Can be reused for multiple years.

How to use: Traps should be used when plants are in fruit. Drosal® Pro traps should be placed around the edge of a planting area, spaced at 1 per 10 m². Hang traps at fruit height, or on tall plants, at least 1 meter high preferably on the shady side of plant. Add approximately 100 ml of liquid attractant to a trap. Traps should be monitored for the presence of SWD regularly. Liquid attractant should be replaced every few weeks and when the level lowers from evaporation.
