The rodenticide fight

Updated November 8, 2026

What's happening

The city finished its part in September. On September 24, 2026 the City Council ordained the ban on anticoagulant rodenticides on city property (26-1310). It also approved Mayor Jake Wilson's home-rule petition to regulate them on private property citywide (26-1257). Both passed 10-0, with Ward 2 Councilor JT Scott absent (Legistar), and Legistar records Wilson's approval of both on September 29. The petition now needs a legislator to file it at the State House; it's tracked on Beacon Hill bills.

The story

Ward 7 Councilor Emily Hardt and At-large Councilor Jonathan Link filed the ordinance, which writes existing city practice into Chapter 6. Ward 4 Councilor Jesse Clingan and At-large Councilor Will Mbah co-sponsored. In early 2024 the residential rodent program replaced second-generation poison blocks with a vitamin D bait. The new bait is far safer for the owls, hawks and coyotes that eat poisoned rats. "It doesn't make sense to continue down a path that we know is not working," Link said. Public Health Director Colin Zeigler explained why there are two tracks. The state licenses pest-control contractors and regulates pesticides, so Somerville can't ban the products they use on private property without Beacon Hill. "Hopefully this moves the state to ban them," Wilson said. Legislative Matters recommended both measures 5-0 on September 15 (Sept 15 digest).

The rats haven't gone anywhere. On September 24 the Council sent At-large Councilor Ben Wheeler's order on dumpster licensing and enforcement (26-1421) to committee for discussion. On September 30, Public Health and Public Safety recommended marking the resolution asking DPW to buy latched trash barrels (26-0708) work completed (Legistar). The Oct 8 digest says DPW is still evaluating the barrels (Oct 8 digest). The same committee returns to rats on November 10, when officials and staff "try to figure out issues around dumpsters and food waste" (Independent, Nov 8).

What's next

  • November 10, 2026, 6:30 p.m.: Public Health and Public Safety on rats, dumpsters and food waste, alongside the warming center.
  • Pending: DPW's decision on latched barrels, now that the committee has recommended closing the Council item.
  • January 4–5, 2027: the legislative session ends. The petition dies if it hasn't passed by then (Beacon Hill bills).
  • This stub can be deleted in December.
