1. Boardman Entrance Feeder with Reduced Access
Easily monitor your hive's sugar syrup levels without disturbing your bees using this sturdy, pre-assembled wooden entrance feeder. Simply attach a standard mason jar (not included) to provide convenient and visible bee feeding.
Boardman feeders sit right at your hive entrance, which sounds counterintuitive for preventing robbing. But here’s the thing, when you pair them with entrance reducers during vulnerable times, your bees can defend a smaller opening while still accessing feed.
The design is straightforward: an inverted jar or bottle sits in a wooden base that slides into your entrance. Your colony guards the feed naturally because it’s inside their defensive perimeter, not exposed in the open where every bee within flying distance catches the scent.
How It Prevents Robbing Behavior
The reduced entrance creates a natural choke point that your bees can actually defend. Instead of robbers flooding in from multiple angles, they face your guard bees at a narrow gate they already patrol.
Think about it this way, would you rather defend a wide-open door or a single narrow passage? Your bees make the same calculation. When you reduce that entrance to just one or two bee-widths during feeding times, even a weak colony can mount an effective defense.
The positioning also means any fighting happens outside the hive rather than contaminating stored honey and brood. You’ll see skirmishes at the entrance, but they won’t escalate into full-scale invasion if your entrance is properly sized.
One caveat: Boardman feeders work best when robbing pressure is moderate, not during a full-blown dearth when every colony in the area is desperate.
Best Use Cases for Hobby Beekeepers
Use Boardman feeders when you’re supplementing strong colonies that just need a boost between flows. They’re particularly useful in early spring when your bees are building up but natural nectar isn’t flowing yet.
They’re also practical for medication delivery, you can easily add treatments to small amounts of syrup without wasting product or creating excess feed that attracts trouble. The small capacity (typically one quart or less) means you’re feeding exactly what your colony can take in a day or two.
Avoid Boardman feeders during fall feeding when robbing pressure peaks and you need to deliver large volumes quickly. Their small capacity becomes a liability when you’re trying to get 20-30 pounds of sugar into a hive before cold weather hits.
For beginners working with just one or two hives, these feeders offer an affordable entry point, usually $10-15 for the base, and you can use canning jars you already own.
2. Frame Feeder with Internal Access Only
Frame feeders replace a single frame inside your hive, putting syrup exactly where your bees are without creating any external access point. Robbers literally can’t reach the feed unless they fight their way through your entrance, past guard bees, and into the brood box.
These feeders look like a deep frame but hold syrup instead of comb. Your bees access the feed from inside the hive, and because the syrup isn’t generating external scent trails, neighboring colonies don’t even know you’re feeding.
Installation and Placement Tips
Place your frame feeder right next to the brood cluster, typically one or two frames from the edge. Bees cluster for warmth, and they won’t venture far from the brood to reach syrup in cold weather, positioning matters more than most beekeepers realize.
Remove a frame with little to no brood to make space. Never sacrifice frames full of brood just to add a feeder: you’re creating exactly the weakness you’re trying to avoid. If your hive is so packed you can’t remove a single frame, they probably don’t need feeding anyway.
Check that your feeder sits level, any tilt concentrates syrup on one side, which can lead to spillage and fermentation. Most frame feeders have some kind of float or ladder system, but these only work if the feeder maintains proper orientation.
When you first install it, watch your entrance for a few minutes. If you suddenly see orientation flights or unusual activity, you might have spilled syrup during installation. That external scent can trigger robbing even with an internal feeder.
Capacity and Refilling Frequency
Most frame feeders hold 1-3 quarts depending on whether you’re working with deep, medium, or shallow boxes. That capacity lets you feed less frequently than entrance feeders, usually once every 3-5 days during active building periods.
The tradeoff is disruption. Every time you open the hive to refill, you’re breaking propolis seals, releasing hive scent, and potentially triggering defensive behavior that can escalate into robbing if neighboring colonies are on edge.
During high robbing risk periods, late summer and fall especially, plan your refills for early morning or evening when flight activity is minimal. A 9 AM feeding on a warm September day is asking for trouble. That same feeding at 7 AM? Much safer.
Some beekeepers maintain two frame feeders and alternate them, which lets you extend the time between openings. When one’s empty, the other still has syrup, so your colony never experiences an abrupt feed cutoff that might send foragers searching elsewhere and attracting attention.
3. Top Feeder with Sealed Design
Safely feed your bees with this leakproof, 4-gallon top feeder. The galvanized steel screen prevents drowning, and the top-fill design allows easy refills without disturbing the hive.
Top feeders sit directly on your hive boxes under the outer cover, creating a completely enclosed feeding system. They typically hold several gallons, which means you can feed heavily without constant intervention, a significant advantage when you’re racing against seasonal deadlines.
The sealed design is their primary anti-robbing feature. Bees access syrup through screened holes or channels from below, while the solid walls prevent any external access. Even when you’re pouring in gallons of syrup, robbers have no way to reach it.
Why Top Feeders Minimize Robbing Risk
The physical barrier matters more than most beekeepers appreciate. Unlike feeders with external access points, top feeders create zero opportunity for robbers to directly reach syrup, they’d have to fight through your entire colony first.
Scent management is the hidden advantage. When you refill a top feeder, you’re essentially creating a closed loop, the syrup scent disperses inside the feeder chamber, but it’s contained by wooden walls and your hive cover. Compare that to entrance feeders that broadcast “free food” signals across your entire apiary.
The large capacity also means less frequent refilling, which means fewer disruptions during vulnerable feeding periods. Opening a hive even briefly releases pheromones and hive scent that can alert nearby colonies. Every inspection is a potential trigger event.
One consideration: top feeders add significant weight when full. A three-gallon feeder loaded with 2:1 syrup weighs about 25 pounds. If you’re managing hives solo or have mobility limitations, this matters. You’ll need to lift the feeder off to inspect boxes below, and that’s not trivial.
Choosing the Right Size for Your Hive
Match your feeder capacity to your feeding goals, not just your hive size. If you’re doing emergency feeding for a weak nuc, a 5-gallon commercial feeder is overkill, you’ll have stale syrup sitting around fermenting while your small colony slowly works through it.
For fall feeding when you need to get 30-40 pounds of sugar into a hive quickly, larger feeders (3-5 gallons) make sense. You can load them once and let your bees process the syrup over a week or more without additional disturbance.
Consider your climate too. In warm fall regions, you might feed steadily through October or November, making larger capacity valuable. In northern areas where feeding windows slam shut fast, you need maximum capacity to deliver feed before cold weather stops your bees from taking it.
Box compatibility matters, some top feeders only fit standard 10-frame equipment, while others work with 8-frame hives. Measure before buying, especially if you’re running mixed equipment or non-standard sizes.
4. Division Board Feeder for Discreet Feeding
Feed your bees easily with this 2-pack of 3.3L beehive frame feeders. The built-in ladders with grooves ensure bee safety while drinking water or syrup.
Division board feeders are essentially deep frame feeders on steroids, they’re wider (often 2-3 inches) and hold more syrup while still fitting inside your hive body. They create the same internal access advantages as frame feeders but with capacity that approaches top feeders.
The “division board” name comes from their dual function: they can partition your hive box while providing feed, which is particularly useful when you’re feeding a small split or nuc in a larger box. You’re using one piece of equipment to solve two problems.
Advantages Over External Feeders
Internal feeding eliminates the scent trail problem that plagues external systems. When bees carry syrup from a division board feeder to storage cells, they’re moving it through enclosed spaces where the scent doesn’t escape. External feeders create a literal pathway of sugar scent from feeder to entrance.
You also maintain better control over who’s feeding. With external feeders, you’re often inadvertently feeding multiple colonies, wasps, yellow jackets, and whatever else finds the setup. Division board feeders keep feed strictly within your target hive.
The temperature advantage is subtle but real. Internal feeders stay warmer because they’re within the hive’s thermal envelope. In early spring or late fall when ambient temperatures drop at night, your bees will take syrup from an internal feeder when they’d ignore a cold external one.
Installation requires sacrificing 1-2 frames worth of space, which can be a tough call during honey production season. You’re essentially removing productive comb to add a feeder. During buildup or fall feeding, that’s a reasonable trade. During a strong flow when you want maximum honey storage? Less ideal.
Preventing Bee Drowning in Division Feeders
Bee drowning is the primary failure mode with division board feeders, and it’s entirely preventable with proper setup. Bees aren’t good swimmers, they need physical structures to climb on while accessing syrup, or they exhaust themselves and drown.
Most commercial division board feeders include some kind of ladder or float system, wire mesh, wood slats, or plastic structures that break the syrup surface. These work, but they require maintenance. Wax and propolis buildup gradually reduces their effectiveness, especially if you’re reusing feeders season after season without cleaning.
Some beekeepers add their own drowning prevention, wine corks floating in the syrup, small sticks creating a lattice, or even plastic window screen cut to size. The key is ensuring bees always have an easy exit route, even as syrup levels drop.
Check your feeders the day after installation. If you find dead bees floating, your drowning prevention isn’t working properly. Don’t wait to fix it, a feeder that kills bees is worse than no feeder at all. You’re literally weakening the colony you’re trying to strengthen.
Refill strategy matters too. Never fill division board feeders completely to the brim. Leave at least an inch of clearance at the top so bees landing on the lip have space to orient before accessing syrup. That buffer zone saves lives.
5. Baggie or Ziplock Feeder System
Baggie feeders might look improvised, but they’re remarkably effective anti-robbing tools disguised as budget solutions. The concept is simple: fill a one-gallon freezer bag with syrup, lay it flat on top of your frames, cut small slits in the top surface, and close up the hive.
Bees access syrup through the slits while the plastic bag prevents drowning and external access. The entire feeding system is enclosed within your hive, and there’s virtually zero external scent because the bag contains the syrup completely until bees actually consume it.
DIY Setup for Budget-Conscious Beekeepers
You need heavy-duty freezer bags, the one-gallon size works well for most applications. Standard sandwich bags are too thin and prone to failure. When a bag splits and dumps syrup inside your hive, you’ve created an internal robbing situation that’s arguably worse than external robbing.
Keep food fresh and protected from freezer burn with Hefty Slider Freezer Bags. The MaxLock Track clicks closed, ensuring an extra-strong seal with an easy-to-use slider.
Fill bags about three-quarters full, roughly 3 quarts of syrup, and seal them carefully. Remove as much air as possible before sealing: air pockets create instability that can lead to rolling and spillage when bees move across the bag.
Place the bag directly on top of your frames, centered over the brood cluster. Lay it as flat as possible, then use a pin or razor blade to cut 3-4 small slits (about one inch long) in the top surface. Start with fewer, smaller slits, you can always add more if flow is too slow, but you can’t un-cut plastic.
Add an empty hive body or shallow box above your top bars to create space for the bag. The thickness of the filled bag means you need about 2-3 inches of clearance. Your regular inner and outer covers go on top of this empty box.
When to Use Baggie Feeders vs. Traditional Options
Baggie feeders shine during high robbing risk periods when even internal feeders with wooden reservoirs can attract attention during refilling. Because you’re placing sealed containers, there’s minimal scent release during the installation process.
They’re also ideal for emergency feeding situations, you can prepare multiple bags at home, transport them easily, and install them in minutes without mixing syrup in the field or dealing with equipment. When you discover a starving hive during an inspection, speed matters more than elegance.
The low cost makes baggie feeders perfect for new beekeepers managing multiple hives on tight budgets. Five dollars of freezer bags can feed several colonies, whereas commercial feeders run $20-50 each. When you’re starting out with 3-4 hives, that cost difference is meaningful.
Keep food fresh with these Amazon Basics freezer quart bags. Each BPA-free bag features a double zipper closure and a Stand and Fill base for easy use.
Avoid baggie feeders when you need to deliver large volumes quickly, fall feeding especially. Refilling requires opening the hive and replacing bags frequently, which increases disturbance. For heavy feeding, top feeders or large division board feeders make more sense even though higher upfront cost.
Some beekeepers report bees chewing through bags, though this seems more common with lower-quality bags or when bees are stressed. If you encounter this, switching to thicker contractor-grade bags usually solves the problem.
Frequently Asked Questions
What is robbing in beekeeping and why is it dangerous?
Robbing occurs when stronger bee colonies raid weaker hives to steal honey and resources. It can turn a peaceful apiary into chaos and may result in the complete loss of weaker colonies before beekeepers notice the problem.
What is the best anti-robbing feeder for fall feeding?
Top feeders with sealed designs are best for fall feeding. They hold several gallons, minimizing refilling disruptions during high robbing risk periods, and their enclosed system prevents robbers from accessing syrup while allowing rapid feeding before cold weather.
How do internal feeders prevent robbing better than external feeders?
Internal feeders like frame feeders and division board feeders eliminate external scent trails that attract robbers. The syrup stays enclosed within the hive, so neighboring colonies can’t detect feeding activity, and robbers must fight through guard bees to access food.
When is the highest risk period for bee robbing?
Late summer and fall present the highest robbing risk when natural nectar flow stops and colonies become desperate for resources. During these periods, beekeepers should use enclosed feeders and feed during early morning or evening when flight activity is minimal.
Can you prevent bees from drowning in division board feeders?
Yes, use ladder systems, floats, wire mesh, or items like wine corks and sticks to give bees climbing structures. Never fill feeders to the brimâleave one inch clearance at the top so bees can orient safely before accessing syrup.
Are baggie feeders effective for emergency hive feeding?
Baggie feeders are excellent for emergencies because they’re quick to install, inexpensive, and create minimal scent during setup. Fill gallon freezer bags three-quarters full with syrup, place them over frames with small slits cut on top for bee access.
