A signature feature of a Langstroth beehive is the bottom board, which holds the entrance to the beehive and closes the hive at the bottom. All other components of the Langstroth beehive stack rest upon this bottom board. The bottom board you use can be either solid or screened, and both types have their advantages and disadvantages. Beekeepers may choose build the bottom board for their beehives or purchase one. In this article, we’ll be discussing the commercially available bottom boards.
Types of Bottom Boards
As mentioned, the two types of bottom boards used with Langstroth beehives are the screened bottom board and the solid bottom board. Screened bottom boards are used for their help with ventilating the beehive and reducing the severity of Varroa mite infestations. Live mites that fall off bees go through the screened bottom board and fall to the ground. They cannot climb back into the beehive. Due to allowing entry of air into the beehive, screened bottom boards are removed in cold weather or seasons and replaced by solid bottom boards. The main disadvantage of screened bottom boards is that they sometimes cause honey bees to build comb under them, on the outside the beehive.
Solid bottom boards are great for beehive insulation. They keep the heat in the beehive and the cold out. Beekeepers in cold regions are best suited using solid bottom boards, but can have screened ones to use in warm seasons. The smell of the beehive does not escape through the bottom board. It helps with preventing predators finding out the presence of the beehive from the smell. When applying treatments for various pests, parasites and diseases of honey bees, it is best to use a solid bottom board or seal up the screened bottom board you have in place.

Inspection of a Beehive Bottom Board
Beehive maintenance requires you to check on it at certain intervals. During a hive inspection, all parts of the beehive including the bottom board are checked. With a screened bottom board, you should check the slide-out tray if there is one installed. Uncapped cells produce some wax debris in the beehive. It falls onto the bottom board, where it is arrested if the slide out tray is in place. With a solid bottom board however, it remains in the beehive. A screened bottom board allows debris to fall through it, so you might not be able to read much from it.
If the slide-out tray was left in before your inspection, look for Varroa mites being on it, or on the surface of a solid bottom board when you are using one. If there are mites on the bottom board, consider treating the beehive to stop the infestation. Mite fall due to treatments applied prior to inspection helps you to determine their effectiveness.
The slide-out tray can inform you to the presence of wax moths and most other pests and parasites of honey bees. Larvae of wax moths and other pests such as small hive beetles might be found on the tray of the bottom board. Adults too might be lurking there sometimes. Every time you see some sign of pest infestation, analyze the extent of it and decide what treatment to apply if necessary. You should be vigilant about pests and the signs are often found by examining the bottom board. If you do not see the pest itself, its feces might be on the bottom board. Experienced beekeepers can tell the difference between the various types of feces found.
Another thing you should check during inspection is debris on the bottom board. Items falling from the hive will settle there. Often, dead bees and wax are found on the bottom board. Clear the beehive debris during the inspection to maintain good hive hygiene.
When to Remove a Screened Bottom Board
Screened bottom boards are not often suitable for use on a beehive all throughout the year. Despite the advantages they have, a screened bottom board can cause problems in the beehive when used at the wrong time. In cold weather and as winter approaches, it is best to remove the screened bottom board and replace it with a solid one. Sometimes, you can just seal up the screened bottom board using its slide-out tray if there is one installed and everything will be fine.
Screened bottom boards left on the beehive in cold weather, allow cold air and moisture to enter the beehive. There, condensation and excess exposure can kill bees. It causes a lot of resources to be expended in keeping the beehive warm. More bees die because of this and the colony might be left very weak. A sealed hive retains heat better and gives you a strong colony after winter is past. Strong colonies in spring give you higher yields of beehive products at the end of the production year.
When applying treatments to the beehive, it might be necessary to remove the screened bottom board. Application of vapors and fogs requires you to seal up the beehive, so that the treatment vapor does not escape. A screened bottom board will allow escape of the vapors and render your treatment useless or less effective than could be realized. Once the treatment is done and enough time has passed, you may return the screened bottom board to the beehive.
