Mercury Insurance Warns of Evolving Wildfire Risks, Urges Homeowners to Rethink Defensible Space
Event summary
- Mercury Insurance highlights that 90% of home ignitions in wildfires are caused by embers, not direct flame contact.
- Embers can travel miles ahead of a fire, expanding risk beyond traditional fire zones.
- The company recommends a zone-based approach to defensible space, focusing on the immediate 0–5 feet around homes.

The big picture

As fires become more intense and unpredictable, traditional defensible space strategies are being reevaluated, with a greater emphasis on home hardening and granular risk mitigation. This trend could reshape insurance policies and underwriting standards, particularly in regions prone to wildfires.
