How to Remove a Large Number of Drones?

Drones are one of the three types of bees (queen bee, drone, and worker bee). They develop directly from unfertilized eggs. Normally, there are hundreds or even thousands of drones in a colony, and their primary function is to mate with virgin queens. Once the queen has successfully mated, drones become a burden. Let's look at how to remove a large number of drones.

1. Drone Definition
Drones are haploid male bees that develop directly from unfertilized eggs. In a normal situation, a colony contains hundreds to thousands of drones. Drones are larger and more robust than worker bees, and their bodies are darker, usually black. Their heads are nearly round, their compound eyes are larger than those of worker bees and queens, they have 11 segments in their antennae, and they have large wings and short, thick legs.

2. Role of Drones
Drones neither collect nectar nor produce honey like worker bees, nor do they lay eggs and reproduce like queens. However, they play an irreplaceable role. First, virgin queens must mate with drones to produce fertilized eggs; otherwise, they can only produce unfertilized eggs. Second, drones carry genetic material, and the quality of the queen depends largely on the quality and number of drones she mates with.

3. Drone Lifecycle
Drones typically live for 3 to 4 months, but they can live for more than 6 months. A drone mates with a queen only once, and after mating, its reproductive organs detach, leading to its death. Once the queen has successfully mated, drones become unnecessary. When nectar is abundant, worker bees tolerate drones, but when food is scarce, worker bees will drive them out or even bite them to death.

4. Methods for Removing Drones
1.Manual Removal: If there are a large number of drones in the colony, they can be manually removed. For example, one can stand near the hive entrance and crush any drones that appear (drones do not have stingers, so they won't sting). During hive inspections, drones can also be captured and eliminated. However, this method is time-consuming and labor-intensive and is only suitable for small colonies.

2.Destroy Drone Cells: Drones develop in drone cells, which look similar to worker cells but are slightly larger and are often found near the top bars. When inspecting the hive, the drone cells can be destroyed or removed, reducing the number of drones and alleviating the workload for worker bees while conserving resources.

3.Use Drone Excluders: Drones have difficulty passing through or cannot pass through drone excluders. Since drones tend to leave the hive on sunny days, excluders can be installed at the hive entrance between 2:00 and 3:00 PM on a sunny day when drones are out. This prevents the drones from re-entering the hive. Repeating this process two or three times can eliminate most drones.
