Hefting Hives: Checking Winter Stores Without Opening the Box
Use hefting, simple weighing and careful records to judge winter food reserves, spot colonies running light early, and decide when emergency feeding is justified.
By Dr. Anke Roos, Bee health researcher. About the author
Starvation is one of the most avoidable winter losses. Colonies rarely starve because the beekeeper did not care; they starve because nobody noticed stores running out until late winter, when brood rearing increases consumption and opening the hive is difficult.
Hefting, lifting one side of the hive to judge its weight, is the simplest way to monitor stores without breaking the cluster. With a little practice and a consistent record, it becomes a reliable early warning.
Why Weight Matters in Winter
A wintering colony consumes stores steadily, and consumption often rises from late winter as the queen resumes laying. Mild, wet winters can increase consumption because bees are more active without being able to forage. A hive that felt heavy in October can be light by February.
Opening the hive in cold weather disturbs the cluster and chills any brood. Hefting gives you useful information while the roof stays on.
How to Heft Consistently
Stand behind the hive and lift the back edge just a few centimetres off the stand, using your legs rather than your back. Lower it gently. You are not trying to estimate kilograms; you are comparing the hive with itself over time and with other hives of the same type.
Heft each hive at the start of winter, when you know it is well stocked, so you have a reference "feel". Then heft at regular intervals, perhaps every two to three weeks, and note whether each hive feels heavy, medium or light.
Turn the Feel into a Number
A digital luggage scale makes hefting repeatable. Hook it under the floor at the back, lift until the back just leaves the stand, and read the value. Repeat at the front and add the two readings for an approximate total weight. The figure is not laboratory accurate, but it is consistent enough to show trends between visits.
Interpreting What You Feel
Compare like with like. A double brood box with a full super will always weigh more than a single box. Wet woodware, a heavy roof or a brick add weight that is not food. Keep the hive configuration the same between checks, and record any changes.
| Heft result | Likely situation | Sensible next step |
|---|---|---|
| Heavy and stable | Adequate stores | Continue regular checks |
| Noticeably lighter than last check | Consumption increasing | Heft again within a week or two |
| Light compared with similar hives | Stores may be low | Plan emergency feeding on a suitable day |
| Very light, little resistance | Starvation risk | Feed promptly and check cluster position |
| One side heavy, other light | Cluster may be away from stores | Check placement on a mild day |
A hive can starve with honey still in the box if the cluster moves away from stores during a long cold spell. If one side feels much heavier, that is worth a quick look on a mild day.
When and How to Feed in Winter
In cold weather, syrup is generally avoided because bees struggle to process and store it. Fondant or candy placed directly above the cluster, over the feed hole or on the top bars with an eke, is a common emergency feed. Work quickly, disturb as little as possible, and close up promptly.
The winter feeding strategies guide explains feed types in more detail. Follow local advice on timing, especially in regions with long winters.
Keep a Simple Weight Record
Write down the date, the heft rating or scale reading, and the weather. Over a few weeks the trend tells you more than any single reading. In ApiaryPilot you can record these winter checks against each hive and schedule reminder tasks, so light colonies are revisited before they run out rather than discovered in spring.
Common Mistakes
- Hefting only once. A single reading cannot show how fast stores are falling.
- Changing the hive configuration between checks. Extra boxes or bricks distort comparisons.
- Feeding syrup in freezing weather. Fondant is usually a safer emergency feed.
- Opening hives to "have a look". Hefting answers the stores question without disturbance.
- Lifting with your back. Bend your knees and lift only a few centimetres.
Your Next Field Action
This week, heft every hive and give each a rating or a scale reading. Mark the lightest colonies, plan to re-check them within two weeks, and make sure fondant is ready before you need it.
