Bee Welfare in Winter: Colony Survival and Management

Honey bee colonies face significant winter welfare challenges, and beekeeping practices that support colony health through winter are essential for both bee welfare and pollination services.

Key Facts

Winter losses of honey bee colonies average 30-40% annually in the United States
Colonies require at least 18-25 kg of honey stores to survive winter in temperate climates
Varroa mite infestations, if not managed before winter, cause catastrophic colony collapse
Small hive size going into winter is a primary predictor of winter mortality
Climate change is disrupting winter dormancy cycles, creating new management challenges

Welfare Considerations

Winter bee welfare is determined by decisions made throughout the entire preceding year. Colonies that are nutritionally stressed, heavily infested with Varroa mites, or insufficiently populated entering winter face enormous welfare challenges and death rates. Responsible beekeeping practices including autumn Varroa treatment, ensuring adequate food stores (without over-harvesting honey), and maintaining strong colonies are not just good practice — they are ethical imperatives for those who keep bees. Supporting wild bee populations through habitat and avoiding pesticides also contributes broadly to bee welfare.

What You Can Do

Support beekeepers who practice responsible Varroa management and do not over-harvest honey
Plant winter-flowering plants (hellebores, winter aconite, snowdrops) to provide early spring forage
Avoid using systemic pesticides especially in spring when new colonies are building strength
Create habitat for wild solitary bees who do not have managed colonies to rely on
Buy local honey from beekeepers committed to ethical colony management practices
