Almost a quarter of Dutch bee colonies did not survive last winter

During the winter of 2025–2026, 24% of Dutch honeybee colonies were lost.

The upward trend observed in recent years therefore continues.

This is the fourth consecutive year in which winter mortality has exceeded 20%.

The figures are based on the annual survey of Dutch beekeepers.

The results show substantial regional differences.

Groningen recorded the highest winter losses, at 41.5%, while Overijssel had the lowest figure, at 16.9%.
