For swarm collectors

Swarm alerts

When someone reports a swarm on our website, everyone on the swarm list gets an alert on their phone straight away, with roughly where it is. The full report, including the caller's phone number, still comes by email.

Got an alert?

Alerts include where the swarm is and a short description, never the caller's name or number. You can stop them at any time on this page or in your phone's settings. See our privacy notice.
