Scent integration

Apply a few drops of lemongrass or peppermint essential oil to the top bars of both colonies several hours before combining them. Alternatively, feed both hives sugar syrup infused with a drop of anise extract. This masks each colony's distinct odor and reduces aggression during the merge.

Why It Works

Bees identify nestmates primarily by colony-specific pheromone profiles. Introducing a strong, shared scent temporarily overrides these odor signatures, making bees from both hives less likely to treat each other as intruders.

Tips

• Use only food-grade essential oils in small quantities -- one or two drops per hive is sufficient
• Combine scent integration with the newspaper method for the highest success rate
• Apply the scent to both colonies equally so neither group smells foreign
• Avoid using synthetic fragrances, which may contain chemicals harmful to bees
