Beekeeping Glossary
Essential beekeeping terms — from frames to foragers.
BAIT HIVE
An empty hive or box set up specifically to attract a passing swarm looking for a new home. Scout bees inspect potential cavities and report back to the swarm cluster, and a well-placed bait hive can intercept them before they move into a tree or wall. Old comb, a few drops of lemongrass oil, and ideal placement — around 15 feet off the ground near known swarm activity — dramatically improve your odds.
BEARDING
A behavior in which large numbers of bees cluster on the outside of the hive, typically on the front face or beneath the bottom board, resembling a beard. It commonly occurs on hot, humid nights when bees move outside to reduce heat and moisture inside the hive, and is generally not a cause for alarm.
BEE BLOWER
A high-powered blower used to clear bees from honey supers at harvest time. Rather than brushing bees off frame by frame, beekeepers using a blower direct a strong airflow through the super, pushing bees out quickly and efficiently. It is fast and gentle on the bees when used correctly, though the noise and wind can temporarily rile up a hive. Most useful when harvesting large numbers of supers at once.
BEE BREAD
Pollen that worker bees have packed into comb cells, mixed with nectar and beneficial microorganisms, and allowed to ferment slightly. This fermentation makes bee bread more digestible and shelf-stable than raw pollen, and it is the primary protein source for growing larvae and young nurse bees. Its color varies widely depending on what flowers the bees are visiting — a single frame can look like a stained-glass window of yellows, oranges, and grays.
BEE BRUSH
A soft-bristled brush used to gently sweep bees off frames during inspections or harvest. A good bee brush does its job without injuring bees or triggering alarm pheromones. Some beekeepers prefer it to shaking bees off frames, especially when working with fragile comb. Look for long, pliable bristles — stiff brushes annoy bees and can crush them. A little practice makes brushing feel natural and smooth.
BEE ESCAPE
A one-way device placed between honey supers and the brood box the evening before harvest. Bees move down through it naturally overnight but cannot find their way back up, leaving the supers largely bee-free by morning. The most common design is the Porter bee escape, a small plastic or metal insert fitted into an inner cover. It is a calm, chemical-free way to clear supers without a blower or brush.
BEE LOUSE
Braula coeca, a wingless fly that lives in honey bee colonies and clings to adult bees, particularly queens, to steal food during trophallaxis. Though often confused with Varroa mites, bee lice are harmless to individual bees and rarely present in numbers large enough to cause colony problems.
BEE METAMORPHOSIS
The four-stage developmental process all honey bees go through: egg, larva, pupa, and adult. Each stage takes place inside comb cells and is carefully tended by nurse bees. The transformation from a tiny curled larva to a fully formed adult bee — with wings, legs, sensory organs, and complex behaviors — happening silently inside a wax cell is one of the quiet wonders you witness every time you inspect a healthy hive.
BEE SPACE
The critical gap measurement — roughly 3/8 of an inch (about 9.5mm) — that honey bees leave open as a passageway inside the hive. Spaces smaller than bee space get sealed with propolis; larger gaps get filled with brace comb. Reverend Lorenzo Langstroth's recognition of this principle in 1851 made removable frames possible and transformed modern beekeeping. Every well-designed hive component is built around maintaining proper bee space throughout.
BEE VEIL
Protective headgear designed to keep bees away from your face and neck — the areas where stings are most alarming and uncomfortable. Veils come in several styles: round, square, and fencing-style, each attaching differently to a hat or hood. Wearing a veil is non-negotiable for most beekeepers, regardless of experience level. Even the calmest colony has moments of unpredictability, and protecting your face lets you inspect with confidence rather than anxiety.
BEE VENOM
The complex mixture of proteins and peptides a bee injects through its stinger. The primary active component is melittin, which triggers pain and inflammation. Worker bee venom is delivered through a barbed stinger that detaches after stinging a mammal, causing the bee to die. Queen stingers are smooth and reusable. Most people experience only local pain and swelling, though a small percentage have serious allergic reactions — knowing the difference matters.
BEEHIVE
The managed structure where a honey bee colony lives, works, and raises its young. Modern beehives are deliberately designed to mimic the cavity dimensions bees naturally prefer, while giving beekeepers easy access for inspections. The Langstroth hive is by far the most common in the US, though top-bar and Warre designs are popular alternatives. A beehive in good condition is a self-regulating, thermally efficient, and remarkably productive little ecosystem.
BEESWAX
The natural wax honey bees produce from specialized glands on the underside of their abdomens. Worker bees chew and shape tiny wax flakes into the precise hexagonal cells that make up honeycomb. Beeswax requires a significant investment of energy — bees consume roughly eight pounds of honey to produce one pound of wax. Beyond the hive, it has countless uses in candles, cosmetics, wood polish, and food preservation.
BOARDMAN FEEDER
A simple, inexpensive entrance feeder consisting of an inverted jar that fits into a wooden or plastic holder at the hive entrance. Bees access the syrup through small holes in the jar lid. Boardman feeders are easy to monitor and refill without opening the hive, making them popular with beginners. However, they can trigger robbing from neighboring hives and are not well-suited for cold-weather feeding when bees cluster away from the entrance.
BOTTOM BOARD
The floor of the hive that all the boxes sit upon. Standard solid bottom boards provide a landing platform and protect the colony from drafts. Screened bottom boards — with a mesh floor and removable sticky board — are widely used in integrated pest management, allowing beekeepers to count varroa mite drop as a monitoring tool. The choice between solid and screened involves tradeoffs in ventilation, moisture management, and pest monitoring strategy.
BRACE COMB
Irregular comb that bees build to bridge gaps between frames, boxes, or between comb and the hive wall — essentially any space larger than bee space that the bees decide to fill. Brace comb makes inspections harder and can connect frames together in frustrating ways. Regular inspections and proper equipment spacing minimize it, but some brace comb is simply a fact of beekeeping life. A hive tool and a little patience handle most of it.
BRAULA COECA
A tiny, wingless fly — sometimes called the bee louse — that lives on the bodies of honey bees and queens, stealing food directly from their mouths. Braula coeca is not a true parasite in the damaging sense; it causes little direct harm, though heavy infestations on queens can be disruptive. Once widespread, it is now uncommon in many parts of the US, partly because varroa treatments have coincidentally suppressed it as well.
BROOD
The collective term for all developing bees inside the hive — eggs, larvae, and pupae at every stage before they emerge as adults. Healthy brood is one of the most important things to evaluate during an inspection. It should be laid in a tight, consistent pattern with few empty cells scattered through it. The brood nest is the warm, carefully maintained heart of the colony, and understanding what healthy brood looks like is a foundational beekeeping skill.
BROOD BREAK
A deliberate or natural interruption in queen egg-laying that results in no new brood being raised for a period. Brood breaks are a valuable integrated pest management tool because Varroa mites reproduce inside capped brood cells, and a brood break disrupts the mite reproductive cycle.
BROOD CHAMBER
The section of the hive where the queen lays eggs and young bees are raised — typically the lowest one or two boxes in a Langstroth setup. The colony works hard to maintain the brood chamber at a precise temperature near 95°F (35°C) regardless of outside conditions. Beekeepers generally leave brood chamber honey for the colony's own use and harvest only from supers placed above, respecting the essential role this space plays in colony survival.
BROOD NEST
The area of the hive where the queen lays eggs and where brood is reared, typically occupying the lower boxes in a Langstroth hive. Bees maintain the brood nest at a precise temperature of approximately 93-95 degrees F regardless of outside conditions.
BURR COMB
Irregular wax comb that bees build in unintended spaces — between frames, on top bars, or along hive walls. Bees fill any gap larger than about three-eighths of an inch (bee space) with comb, and any smaller gap with propolis. Regular inspections let you scrape burr comb away before it complicates frame removal or traps your queen.
