Hive Management

Part of Beekeeping

Regular hive inspection and frame management are the core skills that separate a productive colony from a failing one. Understanding what a healthy colony looks like at each season allows you to intervene before problems become fatal — preventing swarms that cost you half your workforce, catching diseases before they spread, and ensuring the colony enters winter with enough food and population to survive.

Inspection Principles

When to Inspect

• Spring: Every 7–10 days once daytime temperature exceeds 14°C. The colony is expanding rapidly and swarming is imminent.
• Summer: Every 10–14 days. Monitor honey stores, queen laying pattern, and space.
• Autumn: Monthly through September/October. Assess winter stores and treat for varroa if needed.
• Winter: Do not open the hive when temperatures are below 10°C. Inspect only through the entrance or by heft test.

Never inspect in cold (below 12°C), rain, or high wind. Chilled brood dies within minutes of exposure. A stressed colony that is inspected in poor conditions may abscond or become persistently defensive.

Equipment and Approach

• Light the smoker with dry wood chip or burlap. Puff smoke at the entrance before opening, and under the cover when lifting. Smoke triggers bees to gorge on honey (a fire-escape response) and masks alarm pheromone.
• Work slowly and deliberately. Avoid crushing bees — crushed bees release alarm pheromone that recruits stings.
• Wear a veil at minimum. Gloves sacrifice sensitivity but are valuable for beginners.

Reading the Frames

Healthy Brood Pattern

A productive queen lays in a tight, concentric pattern — called “solid brood.” A comb with many empty cells scattered among capped brood (shotgun pattern) indicates disease, a failing queen, or chalkbrood.

Indicator	Healthy	Problem
Brood pattern	>80% cells filled, few gaps	Scattered, many skipped cells
Capped brood color	Tan to light brown	Dark brown, sunken, perforated
Larvae appearance	White, glistening, C-shaped	Off-white, twisted, dried out
Queen cells	None (outside swarm season)	Multiple (swarm or supersedure)
Eggs visible	Single upright egg per cell	Multiple eggs per cell (laying worker)

Assessing Food Stores

Hold a frame up to the light and estimate the proportion of cells containing:

• Honey: Capped with light-colored wax. Feels heavy.
• Pollen: Brightly colored (yellow, orange, red, purple), packed in cells adjacent to brood.
• Brood: White larvae or capped cells.

A full Langstroth frame holds approximately 2.7 kg of honey. A deep brood box with 10 full frames holds roughly 27 kg — more than a colony needs for a moderate winter (see Leave Enough).

Seasonal Management

Spring Expansion

As the colony expands, it will run out of space and prepare to swarm if you don’t intervene. Swarm prevention is the single most important spring management task.

Checklist (every 7-day inspection):

• Is there empty comb for the queen to lay in? Add a frame of drawn comb if fewer than 3 empty frames remain.
• Are there queen cells? (elongated, acorn-shaped cells on frame edges or faces)
• Is the brood box 80% full? Add a super above a queen excluder.

Summer Management

• Ensure adequate ventilation — tilt the hive forward 5° so condensation drains out.
• Add supers before the bees need them; they are reluctant to draw comb in a nectar dearth.
• Check for laying workers (multiple eggs per cell, small worker-sized larvae in drone cells) — this indicates a queenless colony that has been queenless for more than 3–4 weeks.
• Monitor varroa mite levels (see Pest Management).

Autumn Preparation

Task	Timing	Action
Varroa treatment	After last honey harvest	Oxalic acid or thymol treatment
Feed assessment	September	Heft test — lift rear of hive. Should feel very heavy.
Fondant feeding	September–October	Feed 2:1 sugar syrup or fondant if stores feel light
Mouse guard	October	Fit metal strip over entrance reducing to 7 mm gap
Remove supers	October	Remove all honey supers before winter

Winter

The colony clusters around the queen for warmth. They do not hibernate — they continue generating heat by vibrating their flight muscles. They consume approximately 1–2 kg of honey per week in cold climates.

• Do not disturb the cluster unnecessarily.
• Ensure ventilation (condensation is more lethal than cold — slightly prop the lid or use a ventilated crown board).
• Heft check monthly: Lift the rear of the hive. A hive that has become alarmingly light needs emergency feeding with fondant placed directly on the frames above the cluster.

Splitting Colonies

Splitting divides one colony into two, preventing swarms and increasing colony numbers.

Walk-Away Split

The simplest method — requires no queen introduction.

1. Identify the frame with the queen (look for eggs; the queen will be near recent eggs).
2. Place this frame plus 3–4 additional frames of brood, bees, honey, and pollen into a new hive body.
3. Leave the original hive in place. Move the new split to a location at least 3 km away (or bees from the split will return to the original hive).
4. The split with the queen continues normally. The original colony, now queenless, will raise a new queen from existing young larvae (the youngest larvae, ideally less than 3 days old, will be selected).
5. New queen emerges in 16 days (for honeybees), mates over the following week, and begins laying about 28 days after the split.

Check the queenless half 5 days after splitting. You should see queen cells being constructed on frames containing young larvae. If no queen cells are visible, the colony has no young enough larvae — you may need to introduce a frame of young brood (eggs and larvae under 3 days) from the queened half.

Splitting with a Purchased or Caught Queen

If you have a mated queen available (from a split, a caught swarm, or purchase):

1. Make the split as above, ensuring the split you want to queen is queenless.
2. Introduce the queen in a queen cage (a small wooden or plastic cage with one end plugged with candy).
3. Hang the cage between frames, candy end up.
4. Bees eat through the candy over 3–5 days and release the queen. This gradual release allows the bees to accept her pheromones before direct contact.

Never release a new queen directly into a queenless colony — she will almost certainly be killed by workers who haven't yet accepted her scent.

Frame Manipulation

Rotating Frames

Move older, darker frames (more than 3–4 years) to the edge of the brood nest to be slowly emptied by bees and removed. Dark comb accumulates pesticides, pathogens, and smaller cell sizes that may stress bees. Introduce fresh foundation or drawn comb at the center of the brood nest.

Equalizing Colonies

If one colony is weak and another strong, transfer 1–2 frames of sealed brood (no queen, no eggs — just capped pupae) from the strong hive to the weak one. The emerging bees boost the weak colony’s population. Brush adult bees off the frame before transfer to prevent introducing the wrong queen.

Emergency Queen Rearing

If a colony is queenless and has no queen cells, introduce a frame with eggs and very young larvae (less than 3 days old). Workers will select several cells and begin building emergency queen cells. The first virgin queen to emerge will usually destroy her rivals in their cells.

Hive Management Summary

Inspect every 7–10 days in spring and 10–14 days in summer; avoid inspections in cold or rain. Read frames for brood pattern quality, food stores, and queen cells. Prevent swarming by ensuring space and removing queen cells. Prepare colonies for winter with adequate stores (15–20 kg minimum in temperate climates), varroa treatment, and mouse guards. Split strong colonies to increase numbers using walk-away or queened splits. Rotate old comb out of the brood nest every 3–4 years.
