Lemon grass
strongly attracts bees by mimicking the queen bee's Nasonov pheromone, acting as a powerful lure for swarms to new hives or swarm traps, helping beekeepers establish colonies, though it's best used in unoccupied spaces to avoid attracting robbers or disrupting established hives. Beekeepers use it to guide new colonies to a home, attract swarms, and strengthen weak hives.
