The latest complete national survey reported an annual U.S. honeybee colony loss of 48.2% for the 2022-2023 season. Full-year 2026 statistics are not yet published, but the structural pressures are stable. This page compiles verified loss rates and reported causes to frame the 2026 outlook. Annual loss above 40% forces beekeepers to replace nearly half their stock each year, which raises costs and makes winterizing hives a critical part of loss control.
Annual loss above 40% is no longer an outlier. It has become the operating reality for many U.S. beekeepers. Replacing dead colonies often costs more than preventing the loss, especially when queen orders and package bee purchases spike in spring. Our varroa mite treatment guide shows why early mite control beats replacing bees later.
The Honey Bee Health Coalition and USDA Agricultural Research Service both identify varroa mites and the viruses they transmit as the leading management factor in colony mortality. Mite loads above treatment thresholds can reduce worker population, shorten colony lifespan, and increase fall queen failure. Regular monitoring gives beekeepers a measurable way to cut loss rates.

Frequently Asked Questions
Are 2026 honeybee colony loss statistics available yet?
No. Full-year 2026 data will not be available until surveys close and organizations like Bee Informed Partnership and USDA NASS release reports. The most recent complete national survey covered the 2022-2023 season. Beekeepers should check those sources for updated figures.
What annual colony loss rate is considered normal?
Historically, annual losses around 15-20% were considered sustainable. Recent survey years have frequently exceeded 40%. At that level, beekeepers must replace a large share of their operation each spring.
What is the biggest cause of honeybee colony decline?
Varroa mites remain the leading cause. Mites feed on pupating bees and transmit deformed wing virus and other pathogens. Untreated mite levels can collapse a colony within one to two seasons. See the varroa mite treatment guide for monitoring and treatment steps.
How can beekeepers reduce colony loss in 2026?
Start with regular alcohol wash or sugar shake mite counts. Then combine early fall feeding, young queens, and winterizing hives to reduce stress. Good records from each hive inspection also help identify failing colonies before loss peaks.
Do pesticides cause most honeybee colony losses?
Pesticides are a real risk, but national surveys do not rank them as the leading cause. Acute kills happen, especially during crop bloom or when products are misused. Varroa mites and queen failure more consistently drive annual loss rates.
Where can I order replacement bees for 2026?
If you face high loss, plan early. Package bees and nucs often sell out by late winter. Our buying bees guide compares package, nuc, and split options for rebuilding colonies.
