Warm Winters Push North American Bee Swarms Forward, Upending Beekeeping

North America’s 2026 bee swarm season began about 17 days earlier than last year, a shift linked to unusually warm winters and climate-driven changes in flowering that are accelerating bee activity; this follows years of record colony losses and, compounded by resilient varroa mites and competition with wild bees, raises concerns for pollination-dependent agriculture valued at roughly $15 billion and is prompting beekeepers to rethink seasonal management.
