Solid Bottom Board | Yellow Pine Wood

The solid bottom board is the floor your hive stands on — a closed yellow pine base that keeps the nest warmer in cool weather and gives a colony a draft-free footing. It sits under your brood box on any standard Langstroth hive and works with an entrance reducer to control the doorway. Available in 5, 8, or 10 frame.

Features

• Solid yellow pine floor — a closed base that holds heat
• Reversible rim sets a deeper or shallower entrance on most sizes
• Pairs with an entrance reducer for winter and robbing season
• Fits standard Langstroth equipment in 5, 8, or 10 frame

How it works in real life

Set your brood box directly on the bottom board, entrance to the front. The solid floor keeps a colony warmer than an open screened base, which is why many keepers run solid boards for cold-climate wintering or any time they want a closed bottom. On most sizes you can flip the board to raise or lower the entrance height, and slide an entrance reducer in during winter, dearth, or while a young colony is still building up and vulnerable to robbing.

Before you order

Choose the size that matches your hive body — 5, 8, or 10 frame. This is a solid floor, so it doesn't drop mites or vent like a screened board; if you want airflow and Varroa monitoring, see the screened versions below.

• Screened Bottom Board — open mesh floor for ventilation and mite drop
• Screened Bottom Board with Insert — mesh floor plus a removable counting tray
• Entrance Reducers — control the doorway through winter and robbing season
• Wooden Inner Cover — the matching solid top cover

FAQ

What are the dimensions?

Each board is built to the standard Langstroth footprint for its frame count — a 10-frame board matches a 10-frame box, 8-frame matches 8-frame, and so on — so it lines up with any standard equipment of the same size.

Solid or screened — which should I run?

Solid floors keep the nest warmer and are favored for cold-climate wintering. Screened floors add ventilation and let Varroa mites drop out of the hive. Many keepers run screened most of the year and close the floor for winter.

How does the reversible entrance work?

On most boards you can flip the board to set a taller or shorter entrance, then add an entrance reducer to narrow the opening during winter, dearth, or robbing.

Which size do I order?

Match it to your hive body — 5, 8, or 10 frame.
