Connect People and Beekeepers

Connect People and Beekeepers

We help homeowners report swarms and alert local beekeepers fast.

This protects bees, supports backyard biodiversity, and turns each swarm into a data point for science.

Support Outreach

Support Outreach

We work with beekeepers to share educational materials and partner with local groups.

Our aim is to turn honey bee swarms into opportunities for learning and citizen science.

Share Swarm Data

Share Swarm Data

We collect, organize, and publish swarm data for public use.

Our goal is to help scientists, educators, and land stewards make informed decisions about habitat, health, and biodiversity.

Report a Bee Swarm

Reporting bee hives and swarms to beekeepers protect bees and your community.

3. Bees Are Safely Relocated

The colony is carefully relocated to a managed beehive where it can thrive.

Biomonitoring with Bees

Swarms are how healthy colonies split and expand, but they're rarely recorded. By monitoring this overlooked behavior, we can share new insight into pollinator health and ecosystem resilience.
