What is the main benefit of using a screened bottom board in beekeeping?

The primary benefit of using a screened bottom board in beekeeping is that it assists in the control of pests, particularly Varroa mites. A screened bottom board allows for fallen mites and other debris to drop through the screen and exit the hive, reducing the population of these harmful pests. This is crucial because Varroa mites are one of the most significant threats to honeybee colonies, leading to weakened bees and potential colony collapse if not managed properly.

Additionally, the use of a screened bottom board provides an opportunity for better monitoring of mite levels, as beekeepers can observe the number of mites that fall through the screen. This can inform management strategies and the timing of treatments. While elements such as maintaining hive temperature, increasing honey production, and improving ventilation can be associated with hive design, these are not the primary purpose of a screened bottom board. Its main function is focused on integrated pest management, highlighting its importance in maintaining healthy bee populations.
