Droso-Trap is a trap that has been specially designed to effectively attract the Spotted Wing Drosophila (Drosophila suzukii). This trap allows for early detection of the presence of the pest in susceptible crops such as fruit trees and berries. Once trapped inside the Droso-Trap, the adults end up drowning in the attractant liquid. For best results, please use Dros'Attract Food Attract.
