I have reason to believe that the hive I found full of poop recently might not have Nosema, but I’ve been dealing with it, just to careful, as if it does have Nosema. Here’s a long video of me digging into the mess and dealing with it by knocking the colony down to a single medium super. I may update this post with more information later. I’m kinda busy at the moment trying to become an expert on Nosema. (Update: In the video, I leave an open feeder full of thin sugar syrup so the bees could clear out their guts of possible Nosema spores, but I changed my mind and removed it the next day. The risk of spreading Nosema through the syrup seemed too great. Maybe the risk is low, but I don’t want to take any chances.)
“Don’t use open feeders for your bees… unless you know what you’re doing.” That’s the common wisdom flying around the backyard beekeeper’s world these days, and it’s a smart rule to follow. So, naturally, I had to try open feeding to find out for myself.
This isn’t the most informative video. I’ve written in detail about opening feeding in other online forums. While I understand why it’s generally discouraged, one doesn’t have to look far to see commercial beekeepers using open feeders in the spring to get their bees off on the right track.

New beekeepers are usually told to never feed their bees using an open feeder because it can trigger robbing and fighting instincts in the bees, transforming them into bees that are not fun to be around. The bees act like they’re hepped up on caffeine. They behave frantically. As usual, I don’t believe anything until I try it myself and, indeed, through the wonderful world of experiential learning, I discovered that open feeding can have that effect on the bees. But not always.
In my experience, any sugar syrup close to the hive, whether in an open feeder or spilled on the ground, can trigger the robbing instinct, especially if the syrup is spiked with something like anise extract. However, if the open feeder it placed 30 metres or so from the hive (~65 feet), the bees might crowd in on the syrup, but don’t usually start fighting each other to the death to get at the syrup, and when they fly back to their hives, they don’t try robbing the neighbouring hive of all its honey.
I prefer this method of feeding at certain times of the year — long before or long past harvesting any honey — because it’s so easy to do. I don’t have to load up each hive with a feeder. I just refill the open feeder once it gets empty. Open feeding usually doesn’t last more than week. Continue reading →
