New York's 'War on Rats' Is Actually Working

New York City rat sightings are down 22% in the first seven months of 2026 compared to the same period last year, according to 311 complaint data, the same public hotline people call to report an overflowing trash pile or a rat sighting. The city is on pace for its lowest rat-sighting numbers since before the pandemic.

The city's approach wasn't more traps or poison. It was taking away what rats actually need: easy access to food. For decades, New York put its trash out for collection in plain black plastic bags, piled on the sidewalk, which is essentially a buffet with a thin wrapper. Since 2022, the city's "war on rats" has pushed to containerize that trash instead, sealed, rat-resistant bins instead of bags on the curb.

The clearest evidence for what's actually driving the drop is a pilot program in Manhattan Community Board 9, covering West Harlem, where the city fully containerized trash starting in June 2025. Reported rat sightings there fell 34% in the same seven-month window, a steeper drop than the citywide average, in the one area where the policy has been running longest and most completely.

None of this makes rats disappear from a city of 8.5 million people generating trash every single day. But a 22% citywide drop, with an even bigger drop exactly where the program has had the most time to work, is a real signal that the strategy is working rather than just a claim from a mayor's press office.
