Bees swarm in the spring.  In Colorado, bees swarm from April 15th until the end of the summer with May and June being the busiest months.  A swarm occurs when a hive, wild or managed, becomes overcrowded and the old queen and approximately half of the original hive leaves to find a new home.  Swarms are generally quite docile but they can be disconcerting due to the sheer numbers of bees within the swarm.  It is still a good idea to keep your distance so as to not make the bees feel threatened.

Swarms will eventually leave on their own, once the scout bees have returned to inform the group that they have found a suitable new home. Where it may have taken an hour or more for the swarm to collect, they can be gone in less than a minute once they get word it is time to go.  However, beekeepers prefer to catch the bees as a swarm in case their new home–is yours!

If you are lucky enough to witness one of nature’s most fascinating migrations, a swarm, DO NOT ATTEMPT TO KILL THEM!  Do not spray them with insecticide or water!  These bees are “survivor bees” and are crucial to our environmental health.  Call your local bee swarm hotline. We have beekeepers throughout the state ready to be dispatched to collect the bees and transfer them to a new home.  For FREE!  And, generally, within an hour or two.  Please locate your geographical area and contact the swarm hotline number below.
