Just got a press release from Biobest on its ThriPher pheromones. They "contain a sexual aggregation pheromone to attract Western Flower Thrips." It lures male and female thrips from their shelters and leaves beneficial insects alone.
And the pheromone cones pop right into your sticky card traps. The company says it attracts two to three times as many thrips to the traps, allowing earlier detection of a problem.
