1-2 Vial Pack Swarm Catch contains Nasonov, the orientation pheromone, sometimes called the "come hither" pheromone. On average, swarms will occupy 50-80% of catch boxes with Swarm catch (provided there is a reasonable amount of swarming in the area). Place Swarm Catch lure into a super with empty drawn comb (should not contain honey). You can use a frame with beeswax foundation if frames of drawn comb are not available. Store lures in the freezer until use. - Capture swarms from your own hives thus reducing loss of honey bees. Add to your hive count and honey yield by capturing stray swarms from other hives in the area.
