I've tried a lot of different setups over the years, but I always find myself coming back to pail feeders for bees when the fall feeding season hits. If you've been keeping bees for more than a single season, you know the drill. Sometimes the nectar flow just reduces early, or you've got a new swarm that needs a little boost to build out their comb before the cold sets in. There are a dozen ways to get sugar syrup into a hive, but the humble pail—or bucket feeder, as some call it—is probably the most reliable tool in my shed.
It isn't fancy, and it certainly isn't high-tech, but it solves a lot of the issues that other feeders appear to create. You don't have the drowning issues you see with open troughs, and you don't have the "robbing invitation" that entrance feeders tend to send out to every yellow jacket within the county. It's only a simple, effective way to get your girls fed without making a massive mess.
Why the pail method works so well
The logic behind pail feeders for bees is actually pretty clever once you see it for. It relies on a basic vacuum. You fill a plastic bucket with your syrup—usually a 1: 1 ratio in spring or perhaps a 2: 1 in fall—and then you snap the lid on tight. The lid has a small patch of fine mesh screen or a few tiny pinholes drilled into the center. Whenever you flip that bucket upside down over the hole in your inner cover, a little bit of syrup might drip out in the beginning, but then the vacuum kicks in.
The syrup stays put until the bees come up and pull it through the mesh with their proboscis. It's a bit like a giant version of those gravity waterers you see for chickens or dogs. Because the syrup is only accessible from inside the hive, the bees don't have to leave the heat of the cluster to get a drink, which is a huge deal during those chilly autumn nights.
I also love that these feeders have a superior capacity. Most of the ones I use hold in regards to a gallon or two. If you're using those little internal frame feeders, you're out there every 2 days refilling them. With a pail, I can set it and forget it for per week or so, depending on how hungry the colony is. It saves a lot of back-and-forth trips to the apiary, which my lower back definitely appreciates.
Setting things up without the mess
Setting up pail feeders for bees is pretty straightforward, but there are a number of tricks to avoid wearing the syrup yourself. First, you want to make sure that your lid is seated perfectly. If there's even a tiny gap in that seal, the vacuum won't hold, and you'll finish up dumping two gallons of sticky sugar water right down onto the cluster. That's a death sentence for a hive, especially in cold weather.
What I usually do is fill the pail, snap the lid on, and after that flip it over the spare empty bucket first. You'll hear a "glug" sound, a few tablespoons of syrup will drain out, and then it will stop completely. If this keeps dripping, something is wrong with your seal. Once it's holding steady, I make it over to the hive.
You'll need an extra empty hive body (a deep or a medium box) to go around the pail. You place the pail directly over the hole in the inner cover, then put the empty box around it, and finally, put your outer telescoping cover on top of that. This keeps the feeder protected from the wind and prevents any neighborhood raccoons from trying to get a free snack.
Comparing pails to other feeder types
I've spent way too much money on different gadgets, and I've learned hard way that "more expensive" rarely means "better" in beekeeping. Take the entrance feeders—the ones that resemble a little jar sitting on a plastic tray at the front of the hive. They're great for seeing the syrup level from your kitchen window, but they're notorious for starting robbing wars. When the scent of sugar is right there in front door, every scout bee in a two-mile radius is going to take notice.
Then you have the top feeders, those large plastic troughs that sit on top of the frames. They're fine, but I've found that even with the "bee-safe" ladders, I still end up with lots of drowned bees floating in the syrup. It's heartbreaking to open a hive and see a couple of hundred of your workers gone because they couldn't find their solution of the liquid.
Pail feeders for bees really hit that sweet spot. Since the bees are drinking through a mesh screen, there's zero chance of them falling in and drowning. And since the feeder is tucked away within the hive under the outer cover, the smell of the syrup is much better contained. It stays warm from the heat rising off the cluster, too, which makes it easier for the bees to take it down even when the mercury starts to drop.
A few downsides to remember
Now, it's not all sunshine and roses. The main gripe I have with pail feeders for bees is the storage. When you have ten or twenty hives, you suddenly have twenty extra buckets taking on space in your garage or barn throughout the summer. They don't always stack as neatly as you'd like if the lids have those mesh inserts.
There's also the "mold factor. " If the bees are slow to take the syrup, it can start to ferment or grow black mold around the holes in the lid. I usually try to add a tiny splash of something like Hive Alive as well as just a bit of lemon juice to help stabilize the pH, however you still have to keep a watch on it. If I see the syrup getting cloudy or the bees stop visiting the feeder, I'll take it off, give it a good scrub using a mild bleach solution, and start fresh.
Another thing is that you can't really see how much is left without cracking the hive open. With a clear jar feeder, you understand exactly where you stand. With a pail, you have to lift the outer cover and give the bucket a little "thump" or a lift to feel the weight. It's a minor inconvenience, but something to be aware of if you're a hands-off kind of beekeeper.
Tips for the DIY crowd
If you don't are interested specialized pail feeders for bees , you can actually make your own pretty easily. Any food-grade plastic bucket will work—think of those 1-gallon honey pails or use the smaller icing buckets you can sometimes get for free from bakery departments.
The key is the lid. You can take a very fine drill bit (we're talking tiny, like 1/32 of an inch) and poke about 20 to 30 holes in the center of the lid. Some people choose to use a hot nail to melt the holes, which works too. Just don't go overboard. If the holes are too big, surface tension won't be enough to hold the liquid, and you'll have a mess.
Personally, I prefer the store-bought lids with the stainless-steel mesh. The mesh allows for more "surface area" for the bees to congregate. You'll often see a solid layer of bees hanging upside down on that mesh, happily drinking away. It's much more efficient than making them compete for several tiny drill holes.
When to take the feeder off
Knowing when to stop using pail feeders for bees is just as important as knowing when to start. I usually keep mine on till the bees have filled their winter stores—in my area, that's about 60 to 80 pounds of "honey" (or cured syrup) for a double deep setup. Once the daytime temperatures consistently stay below 50°F (10°C), the bees won't have the ability to evaporate the moisture out of the syrup anyway.
Leaving liquid feed on in its final stages into the winter can in fact do more harm than good by jacking up the humidity inside the hive. High humidity leads to condensation, and cold water dripping on a winter cluster is a recipe for a dead colony by February. When it gets that cold, I swap out the pails for dry sugar or fondant.
At the end of the day, beekeeping is all about observing what your colonies need and reacting. Pail feeders are just one tool, but they're one of the most reliable ones I've got. They aren't flashy, they're a bit bulky to store, and they also might give you sticky fingers once in a while, but for sheer efficiency and bee safety, they're hard to beat. If you're looking for a way to strengthen your hives before winter, give the pail method a shot. Your bees will thank you—mostly by not drowning and by having plenty of food to obtain through the long haul.
