What a National Summit on Urban Rats Revealed About Boston's Own Problem

On September 23 and 24, 2026, Boston hosted the second-ever National Urban Rat Summit, bringing together researchers, public health officials, municipal managers, and pest management professionals from across the country to compare notes on urban rodent control. The first summit was held in New York City in 2024 under the Adams administration. Boston's turn as host doubled as an occasion for the city to show its own two years of work on the problem — and the picture that emerged was candid rather than triumphant.

The report that became a city's action plan

Boston's current approach traces back to a specific piece of research: in 2024, rodentologist Dr. Bobby Corrigan spent months studying the city's rat population and produced a 51-page report that now serves as the backbone of the city's Boston Rodent Action Plan (BRAP), a citywide rodent-reduction effort launched that same year. At the summit, city officials gave an update on BRAP's progress, and Corrigan returned as a keynote speaker — this time offering a notably unvarnished assessment of where things actually stand: "We are still, for the most part, struggling with this mammal."

What's actually changed on the ground

The city used the summit to showcase concrete infrastructure changes rather than just plans. Boston has installed rat-resistant trash receptacles and a composting bin at a Charlestown housing property, and new rat-proof dumpsters are now in use at a Boston Housing Authority complex in Brighton. These are the same basic exclusion principle documented elsewhere — denying rats reliable access to food — applied at specific properties rather than citywide, which is itself informative: this is still working through priority sites rather than a completed rollout.

The disease angle driving the urgency

Part of what keeps this a public health issue rather than purely a nuisance complaint is disease risk. One speaker at the summit noted that rats are associated with roughly 55 different public pathogens, and researchers have separately found that Boston's rats are carrying and spreading leptospirosis, a bacterial disease. That finding sits alongside a simpler, more immediate indicator of scale: Boston's own 311 system currently lists more than 1,700 open reports of rodent activity, a running tally of complaints still waiting on a resolution.

A more experimental approach: contraception instead of poison

Beyond infrastructure and surveillance, Boston is also piloting a genuinely different control method in the Jamaica Plain neighborhood: a fertility-control bait that reduces rat reproduction rather than killing rats outright. It's a notably different mechanism than rodenticide or trapping — targeting population growth at the source rather than removing individual rats after the fact — and reflects the same instinct behind the summit itself: an openness to comparing approaches rather than assuming the standard toolkit is sufficient on its own.

Why an honest keynote matters more than a celebratory one

What stands out about this summit's framing is what it didn't do: claim victory. A city that commissioned a serious scientific study of its own rat population, built a named action plan around the findings, and is still willing to platform a keynote speaker saying the fight remains a struggle, is treating rodent control as an ongoing operational discipline rather than a one-time initiative with a finish line. That's a more honest posture than most municipal pest announcements offer, and it's a useful reminder, at the scale of a single property as much as a city, that rodent control is maintenance work, not a problem that gets solved once.

• Boston hosted the second-ever National Urban Rat Summit on September 23–24, 2026, following the inaugural 2024 summit in New York City.
• The city's Boston Rodent Action Plan (BRAP) is built on a 2024 51-page population study by rodentologist Dr. Bobby Corrigan, who returned as the summit's keynote speaker.
• Concrete changes on the ground include rat-resistant trash receptacles and a composting bin in Charlestown and rat-proof dumpsters at a Brighton BHA complex.
• Rats are linked to roughly 55 public pathogens, and Boston's own rat population has been found carrying leptospirosis; the city's 311 system lists over 1,700 open rodent reports.
• A Jamaica Plain pilot is testing fertility-control bait as an alternative to rodenticide, targeting reproduction rather than removing individual rats.

Boston's experience is a reminder that rodent control works best as ongoing maintenance rather than a single treatment. A free Sevacorp inspection is a practical way to find out what that looks like for one specific property.
