Seeing bees in February might seem unusual, but honey bees can be active even in the winter months. While they typically cluster inside their hive to stay warm, warmer days can trigger short periods of activity. Here's what to do if you spot bees buzzing around in Pennsylvania during the winter.
First, determine if you're seeing a small group of bees simply taking a cleansing flight or something more significant. A few bees flying near the hive entrance on a warmer day is normal. A large cluster of bees away from a hive could indicate a swarm, even in winter, especially in milder parts of Pennsylvania.
If the bees are simply flying around the hive entrance on a relatively warm day (above 50°F), there's likely no cause for concern. They are taking advantage of the opportunity to relieve themselves and reorient to their surroundings.
A cluster of bees away from an obvious hive location, even in winter, needs attention. While less common, swarms can happen during warmer periods. This is especially true in urban areas where microclimates can keep temperatures slightly higher.
Swarmed connects people who find swarms with local beekeepers who can rescue them. Here's why it's a great option:
Seeing bees in the winter in Pennsylvania might be a normal occurrence, but it's always best to err on the side of caution. Report any unusual bee activity to Swarmed to help protect these vital pollinators and support your local beekeeping community.
