Is NYC's rodent complaint volume increasing or decreasing year over year?

NYC 311 rodent complaint volume has declined over the 2023–2025 period. Full-year 2024 saw 2,892 fewer complaints than 2023 (-7% change). Full-year 2025 saw a further 7,544 decline vs. 2024 (-19%). The all-time peak in the measured window was August 2023 (4,559 complaints). The most recent winter nadir was February 2026 (1,183 complaints).

Year-over-year declines in complaint volume may reflect reduced actual rat activity, increased DOHMH abatement effectiveness (including the Rat Mitigation Zone program launched in 2023), changes in 311 reporting behavior, or some combination. Complaint counts are a proxy measure, not a direct rat census.
