Drosal Pro®

Small refillable black lidded cup trap for monitoring Spotted Wing Drosophila (SWD, Drosophila suzukii)

How to use


Traps should be placed at regular intervals (5-10 m) around the edge of a crop and checked regularly.

Drosal Pro® does not include liquid attractant. This should be brought separately. Andermatt recommends using Drosal Pro trap with Drosalure attractant.

Each Drosal Pro® trap should be half-filled with approximately 75 ml of liquid attractant.

Attractant may need to be refilled through the season as liquid evaporates.

Drosal Pro® traps can be used for multiple years. Use fresh attractant each year.


Drosal Pro® is specifically designed for trapping Drosophila suzukii (SWD) flies with its small entrance holes, therefore preventing accidental trapping of non-target organisms. Fewer non-target insects makes assessing trap catches less time consuming.

Accurate monitoring of pests allows more selective use of pest control products.
