Beekeeping Moisture Board
A winter moisture board sits above the inner cover and soaks up the condensation a clustered colony gives off, venting it away through cross-flow so the moisture doesn't drip back down onto the bees. Keeping the cluster dry is one of the biggest factors in overwintering survival. Fits 8- and 10-frame equipment and works in any climate.
Features
- Absorbs hive moisture and vents it through cross-flow ventilation
- Keeps condensation from dripping onto the winter cluster
- Works in any climate
- Available for 8-frame and 10-frame equipment
How it works in real life
Through winter a clustered colony keeps itself warm, and that warmth meets the cold lid and condenses into water. Cold water dripping on bees kills more colonies than cold air alone. The moisture board takes up that excess humidity and lets it evaporate away through the sides, keeping the inside of the hive dry. Set it on top of the inner cover, then put the outer cover over it.
Before you order
Choose 8-frame or 10-frame to match your equipment. Use it over your inner cover, under the telescoping outer cover; it pairs naturally with a screened inner cover for even better airflow.
Pairs Well With
- Wooden Inner Cover — sits beneath the moisture board
- Screened Inner Cover — adds ventilation under the board
- Telescoping Outer Cover — goes on top

FAQ
Where does the moisture board go?
On top of the inner cover, with the telescoping outer cover over it.
Do I need one in a mild climate?
It helps in any climate — wet, mild winters create condensation just like cold ones, and keeping the cluster dry improves survival.
Which size do I order?
Match it to your hive — 8-frame or 10-frame.
Can I use it with a screened inner cover?
Yes — the two work well together for moisture control and airflow.
