Its extra-durable underside ribs are designed for security and strength.You can use it with the corners open, with or without corner caps, or with central access. If you choose, the bees can also have access through the central chimney. For this, you will need to drill the size of holes you prefer. We recommend 1/2 inch. Some beekeepers like large holes, some smaller. The choice is yours. Again, you can choose whether or not to use a chimney cap to protect the bees from drowning in the syrup.Top feeders are great for feeding raw or dry white sugar in the early and midwinter. If you’re feeding in this way, don’t use a “chimney cap”; just let the bees range across the feeder. Raw sugar is considered better, as it has a bit of moisture in it already and the bees can work it and take it up. If using dry white sugar, you may want to add a small damp sponge to the top feeder to give the bees some moisture to work the sugar.If this top feeder isnt what youre looking for, we sell aPremium Beehive Top Feeder. We also carry a variety of entrance feeders, including the hard-wearingWooden Boardman Entrance Feeder.Check out this video for more information.
