Inspecting a colony
A hive inspection is the heart of practical beekeeping. Opening a colony lets you check that it is healthy, well fed and queenright, and gives you the chance to act before small problems become big ones. Done well, an inspection is calm, quick and purposeful. Done badly, it stresses the bees, chills the brood and teaches you very little.
This page covers how to inspect a colony properly. For how to capture what you find in Openbeehive, see recording inspections.
When to inspect
During the active season, a routine inspection every 7 to 10 days is the usual rhythm. Bees can raise a new queen and prepare to swarm inside that window, so longer gaps risk missing the early signs.
Outside the season, leave the colony alone. In autumn and winter, opening the hive chills the cluster and breaks the propolis seal for little benefit. A quick lift to judge weight (hefting) tells you more about winter stores than a full inspection ever could.
Match your inspection frequency to the season. Weekly through spring and early summer when swarming pressure is high; less often once the colony has settled; not at all when bees are clustered for winter.
Choosing the right weather
Pick a day that is good for the bees, not just convenient for you:
- Warm: ideally 15 °C or above, so open brood does not get chilled.
- Calm and dry: wind and rain make bees defensive and hard to handle.
- Middle of the day: when most foragers are out, the hive is less crowded and tempers are better.
Avoid inspecting in a thunderstorm-charged sky, at dusk, or when a nectar flow has suddenly stopped, as bees are often touchy then.
Before you open up
Prepare so you are not fumbling once the hive is open. Have your hive tool, a lit smoker, your record-keeping ready, and any kit you might need (frames, a queen cage, marking pen) within reach.
Lighting the smoker
A well-lit smoker is your most important calming tool. Cool, white smoke prompts bees to move down and feed, making them easier to work.
- Light an easy-catching tinder (dry grass, paper or cardboard) in the base.
- Add slow-burning fuel a little at a time, puffing the bellows to keep it drawing.
- Pack loosely with more fuel until you have a steady, cool smoke.
- Check it produces white smoke, not hot flame, against the back of your hand.
Give a couple of gentle puffs at the entrance, wait a minute, then a little under the crownboard as you open up. Less is more; thick smoke drives bees into a panic rather than calming them.
Never set down a lit smoker on dry grass or near anything flammable. Make sure it is fully out before you leave the apiary.
Working the colony calmly
How you move matters as much as what you do.
- Stand to the side or behind the hive, never blocking the flight path.
- Move slowly and deliberately; avoid sudden movements and knocks.
- Lift and replace frames gently to avoid rolling and crushing bees, which releases alarm pheromone.
- Keep the hive open for as short a time as possible.
Work through the brood box frame by frame in order. Loosen the frames with your hive tool, remove an outside frame first to give yourself room, then examine each frame over the open hive so the queen cannot drop into the grass.
What to look for
You are building a picture of the colony's health. The key questions:
| Check | What good looks like |
|---|---|
| Queen presence | Eggs and young larvae confirm a laying queen, even if you do not see her. |
| Eggs | A single egg standing upright in the centre of cells. |
| Brood pattern | A solid, compact pattern of capped brood with few gaps. |
| Stores | Enough sealed honey and a band of pollen around the brood. |
| Space | Room to lay and store; not honey-bound or overcrowded. |
| Queen cells | Note any cups, charged cells or sealed cells. |
| Disease and pests | No sunken or perforated cappings, foul smell, or chalk/mummies. |
| Varroa | Watch for mites on bees, deformed wings, or signs on the floor. |
| Temperament | Calm bees that stay on the comb are easier and healthier to keep. |
Queen, eggs and brood
You do not need to find the queen every time. Seeing eggs means she was laying within the last three days. A neat, central laying pattern with eggs, then larvae, then capped brood in concentric arcs shows a healthy queen. A patchy or scattered pattern can signal a failing queen, disease, or poor nutrition.
Stores and space
Check the colony has enough food, especially in spring before the flow and in late summer afterwards. At the same time, make sure the queen has empty comb to lay in. A colony with nowhere to expand is far more likely to swarm.
Queen cells
Finding charged or sealed queen cells on the comb is one of the most important things an inspection reveals, as it often means the colony is preparing to swarm. Record their number and stage. See swarming for how to respond.
Disease, pests and varroa
Look closely at the brood for anything abnormal: sunken, greasy or perforated cappings, an unpleasant smell, or chalky white mummies. Watch adult bees for deformed wings or visible mites. Varroa management is a year-round task; see varroa.
If you suspect a notifiable disease such as American or European foul brood, stop, close up, and contact your national bee health authority. Reporting requirements vary by country and are often a legal obligation.
Minimising disturbance
Every inspection is a small disruption. Keep it proportionate. If you only need to confirm the colony is queenright, you may not need to go through every frame. Replace frames in the same order and orientation, close up gently, and let the bees settle.
Recording what you find
An inspection is only as useful as the notes you keep. Record temperament, stores, space, brood and any queen cells or disease signs while the details are fresh, ideally hive-side on your phone. Because Openbeehive is offline-first, you can log everything in the apiary with no signal and it will sync later.
See recording inspections to capture your findings, and the beekeeping section for the wider seasonal context.
