Adhesive monitoring trap with dual attractant action, chromotropic and pheromone, easy to use, to detect the presence of the cherry fly. It is odourless, non-toxic and insecticide-free. Weather-resistant, the chromotropic action in combination with the specific pheromone attracts only the target insects, so it is safe for the environment and other animals.
