Boston is “hopeful” about rat birth control as part of its new rat action plan, according to city officials.

In a webinar last week titled “Rodent Control Starts with You,” two of Boston’s rodent experts explained the Boston Rodent Action Plan (BRAP), a new project announced by Mayor Michelle Wu in July.

The speakers repeatedly emphasized that the best way to combat rats is better trash storage. Residents, however, were particularly curious about rat birth control. Earlier this year, a pilot program in Jamaica Plain, in which residents fed rats fertility blockers instead of rodenticide, showed an apparent decline in rats of up to 60 percent.

In response to resident questions, one official said the city was considering a fertility control pilot for rodents.

“We’re hopeful,” John Ulrich, the city’s assistant commissioner for environmental services, said in the webinar.

“We are talking to one company around fertility control products. We did observe the group in JP and looked at their data. We were looking for a little more data, so [we’re] still in conversations with them, but a tool that doesn’t have a negative impact on the environment. We want all the tools we can get. Fertility control of rodents would be amazing, but more to come.”

The city has previously considered rat birth control as an official part of BRAP, as it is less dangerous for pets, children, and urban wildlife. In July, when the plan was announced, all 13 city councilors voiced support for a potential rat birth control program, moving it to a review committee.

At a hearing in October, however, Commissioner of Inspectional Services Tania Del Rio said that Jamaica Plain’s pilot data was not as good as it seemed, and that the number of 311 complaints of rat sightings in the area had in fact increased. The city’s plan for rat birth control has since been unclear.

Ulrich did not say which rat birth control company Boston was talking to. He said more details would be announced in 2025.

As it stands, the rest of the city’s plan centers largely on getting better garbage bins. Potential pilots in Beacon Hill, the Back Bay and the South End included better litter baskets in parks and policy solutions for residential trash.

“Trash storage is a big one in Beacon Hill,” Ulrich said. “We’re looking at public alley trash storage, regular residential trash, and site cleanliness to try to improve. This one is really focused on public alleys.”

Dennis Roache, the superintendent of waste reduction, said in the webinar that BRAP might also lead to new city requirements for trash disposal.

“Currently, on your trash day, Boston has no containerization rules,” Roache said. “We do pick up bags of trash on the street. The city of Boston is looking at new rules and regulations around that. The more residents take responsibility for containerizing their trash, the less rats we will see in neighborhoods.”
