The size of the entrance hole in a native bee hive varies depending on the specific design and purpose of the hive. Common sizes range from 3/8-inch to 13mm in diameter, with some hives featuring rectangular entrances measuring 3/8-inches high by 3-inches long. The entrance size can often be adjusted or closed using sliding doors, which also serve as mouse guards to prevent rodents from entering. Additionally, the ideal size for a beehive entrance hole, as discovered by Tom Seeley, is between 10 to 15 cm squared, approximately 1.5 to 2.5 inches. This variability ensures that the hive is accessible to bees while protecting them from environmental factors and pests.
Key Points Explained:
-
Common Entrance Hole Sizes:
- The entrance hole in a native bee hive typically ranges from 3/8-inch to 13mm in diameter.
- Some hives feature rectangular entrances measuring 3/8-inches high by 3-inches long.
-
Adjustable Entrances:
- Many hives are equipped with sliding doors that allow beekeepers to adjust the size of the entrance hole or close it completely.
- This feature is particularly useful for controlling the hive's environment and protecting bees from adverse weather conditions.
-
Mouse Guards:
- The entrance hole can also function as a mouse guard, especially during times when rodents are likely to enter the hive.
- The size of the entrance hole in mouse guards is typically around 3/8 inch to 1/2 inch in diameter, allowing bees to pass while preventing mice from entering.
-
Ideal Entrance Size:
- Research by Tom Seeley suggests that the ideal size for a beehive entrance hole is between 10 to 15 cm squared, which is approximately 1.5 to 2.5 inches.
- This size ensures efficient hive management and accessibility for bees.
-
Environmental Protection:
- To protect the hive from rain, it is recommended to use a short length of irrigation hose in the entrance hole.
- This simple modification helps keep the hive dry and maintains a healthy environment for the bees.
-
Full-Sized Hives:
- In full-sized hives, the entrance hole is often kept small, sometimes only a few square inches.
- The larger number of bees in these hives can manage the space more effectively, making a smaller entrance sufficient.
By understanding these key points, beekeepers can make informed decisions about the size and features of the entrance hole in their native bee hives, ensuring the health and safety of their bee colonies.
