Complete guide for overwintering bees — step-by-step workflow, tools, checklist, and expert tips to get started.
Heft hive from rear — aim for 60–80 lb honey equivalent in cold climates; verify queenright compact brood nest.
Apply oxalic acid dribble or vapor after broodless period in late fall when mite count still exceeds threshold.
Ensure upper entrance or moisture quilt board; tilt hive slightly forward for condensation runoff away from cluster.
Heft hives on warm late-February day; add fondant or candy board if weight is light — do not open fully below 50°F.
Track hive weight through fall to confirm 60–80 lb winter stores before sealing for cold season.
Size upper ventilation opening and moisture board configuration for your climate zone.
Confirm final fall mite count is below treatment threshold before winter bee production completes.
Estimate cluster size to decide whether weak colonies should be combined before winter.
Minimum honey stores for overwintering survival.
| Climate Zone | Minimum Stores | Feed Deadline |
|---|---|---|
| Mild (zone 8+) | 40–50 lb | November |
| Moderate (zone 6–7) | 60–70 lb | Mid-October |
| Cold (zone 4–5) | 80–90 lb | Early October |
| Combine threshold | < 4 frames bees | September |
Rear heft tells stores accurately — scale under hive confirms when in doubt.
Bees raised in fall live until spring — mite damage to these bees is irreversible.
Liquid syrup freezes before bees can use it — fondant or dry sugar only in sub-freezing weather.
