Overview
- The 2025 ranking is based on new rodent-service calls logged from August 20, 2024, through August 21, 2025.
- Chicago’s roughly decade-long run at No. 1 ended as it moved to second, with New York third and San Francisco fourth.
- Orkin cites Los Angeles’s year-round warm weather, dense neighborhoods and abundant food sources as key drivers of its rise.
- California is heavily represented on the list, and the top 10 shifted as Hartford and Minneapolis entered while Baltimore and Cleveland dropped out.
- Public-interest advocates challenge the methodology as not scientifically definitive, and Orkin emphasizes prevention steps and health and property risks.
