This product is for an 8-Frame Hive. We also have 10 frame versions listed. Made and shipped from USA! These boxes solve many issues for those who need to winter over their hives. We use these boxes on every hive we have on our farm and so do thousands of other beekeepers, with great success. Letting your bees cluster in the hive like normal is very inefficient. The bees mash between each frame trying to cluster as much as they can to keep warm, but the whole hive doesn’t have a chance to cluster together to stay warm. These winter boxes help the entire hive cluster in one large ball making them MUCH more efficient at keeping warm. Unlike just adding another medium to allow them to cluster, our winter boxes allow for moisture wicking insulation on either side of them and allows for your sugar board or feeder to encourage them to cluster in the best spot in the hive. These boxes allow for insulation to be put on the two compartments on the outside and your candy board or feeder in the middle compartment. The screen on the outer two insulation areas is small enough to not let the bees pass through (or your insulation like sawdust or wood chips), but large enough to let air keep flowing. The middle compartment screen is large enough to let the bees easily travel though, without them even scraping their wings. This center compartment allows your sugar board or feeder to sit on the screen and allows the bees to use the screen to hang on to as they cluster in the middle to stay warm and feed, surrounded by moisture wicking insulation on both sides of them. Please note: The feeders will come with the two inside walls of the feeder raised slightly higher than the rest of the box, this is meant to be used with a screen inner cover over the winter, preventing the bees from getting into the moisture compartments and dying over the winter. We recommend you use a winter screen cover between this feeder and your outer lid because the feeder, when filled with the moisture wicking material and feed, reduces air flow considerably in the hive. With the inner screen cover on all winter, the air flow is better regulated reducing the chances that moisture builds up inside the hive. Please see our other products for the Inner Screen Cover if you wish to purchase it as well. **Please note, the box in the pictures is painted yellow. Your box will not come painted, so slap a fresh coat on paint on it in any color you like! Give your bees a nice warm and cozy spot to spend their winter this year!
