Lemon balm (Melissa officinalis) is considered an excellent natural swarm lure for honey bees because it closely mimics the scent profile of the pheromones bees use to communicate — especially during swarming and nest-finding.
Here’s why lemon balm works so well:
🧪 1. Chemical Similarity to Nasonov Pheromone
-
Honey bees release the Nasonov pheromone to signal other bees to a location, such as a new nest site.
-
Lemon balm contains citral, geraniol, and nerol — volatile compounds that are chemically similar to the components of the Nasonov pheromone.
-
This makes lemon balm smell familiar and attractive to bees searching for a new home.
🐝 2. Attracts Scout Bees
-
During swarming, scout bees search for suitable nesting sites.
-
If they detect lemon balm, they are more likely to investigate and, if suitable, lead the swarm to that location.
🌿 3. Natural and Readily Available
-
Lemon balm is easy to grow, non-toxic, and a low-cost alternative to synthetic swarm lures.
-
You can use it fresh by rubbing the leaves inside a bait hive or by using essential oil.
🏠 4. Enhances Bait Hive Appeal
-
A bait hive smeared with lemon balm (or its oil) mimics a site that has already been visited or claimed by bees.
-
It gives scout bees a chemical signal that the location may be safe and previously occupied.
🧴 How to Use Lemon Balm as a Swarm Lure
-
Fresh leaves: Crush and rub them inside the bait hive or on the entrance.
-
Essential oil: Use a few drops on a cotton ball inside the hive.
-
Reapply regularly: The scent fades, so reapply every few days during swarming season.
🐝 Pro Tip:
To maximize success, combine lemon balm scent with:
-
A properly sized bait hive (about 40 liters)
-
Old brood comb (smells like a used hive)
-
A good location (dry, shaded, 6–15 feet above ground)
Summary:
Lemon balm is a great swarm lure because it mimics bee pheromones, is natural and accessible, and helps scout bees identify a potential new home.
