There is a Northern Colorado Beekeepers Association, which might be able to help.  https://nocobees.org/ (includes a swarm hotline).

Hi Cyndi,

To follow up on what Frank said, you can also join your local beekeeping club. Often, the beekeeping clubs have lists of people waiting for swarms. Here is a list of the Colorado beekeeping clubs: https://coloradobeekeepers.org/resources/bee-associations/

Since you are in Jefferson County, you might consider joining the
Jefferson County Beekeeper Association (JCBA) formerly Green Mountain Bee Group –https://www.jeffcobeekeepers.org/ – Contact: <personal data hidden> 

We've had a weird weather year with all the rain so bees have swarmed later than normal. Typically swarm season ends around June. It might be possible to find a swarm, but the beekeeping club will be able to help further.

Let me know if you have any questions! 

Thanks,

Lisa
