Swarm Commander is a popular beekeeping product that uses a synthetic formula mimicking the natural "Nasonov pheromone" to attract and capture passing feral honeybee swarms, helping beekeepers establish new colonies easily and efficiently. Available as a spray, gel, or crush vial, it's applied inside bait hives or traps to lure scout bees, often outperforming traditional lemongrass oil lures and offering a reliable way to expand apiaries.
