And here are a couple pictures of the modified top feeders. As shown elsewhere on this site, we’ve modified some top feeders we bought from Miller Bee Supply (the green box in these photos) by cutting another hole behind the hole the bees originally used to enter feeder. I then added a dam across the width of the feeder and moved the screen/feeder access back a few inches. The feed chamber is a little smaller yet still holds better than a gallon of syrup, and now the bees can enter and exit the hive from the top. For a bee to get to the syrup from outside, she must pass through the front-most chamber in the modified feeder, crawl down into the hive, then can come back up through the second chamber. The syrup is completely isolated from the entrance.
