SURPRISE, Ariz., Aug. 31, 2026 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), the leader in rodent birth control and sustainable rodent population management, today announced that a six-month deployment of Evolve^® Rat as part of a comprehensive Integrated Pest Management program reduced measured rodent activity by 43% at a municipal facility in Swampscott, Massachusetts.

Municipalities across the country are increasingly seeking more effective, sustainable approaches to reducing rodent populations while minimizing reliance on repeated rodenticide applications. The six-month deployment in Swampscott demonstrates how rodent birth control can complement Integrated Pest Management programs by supporting long-term rodent population management.

Fire stations and other municipal facilities often provide ideal harborage and food sources for rodents because of refuse collection areas, landscaping, and surrounding infrastructure. Beginning in September 2025, the Town of Swampscott deployed 20 Evolve^® Rat bait stations around the perimeter of a municipal fire station experiencing ongoing rodent activity as part of a comprehensive Integrated Pest Management program that also included sanitation and waste management improvements.

The program incorporated sanitation improvements, enhanced waste management, and long-term rodent birth control to address both the conditions that attract rodents and future population growth. As part of the Integrated Pest Management strategy, the Town upgraded refuse handling around the facility by replacing several plastic trash containers with a metal dumpster, reducing rodents' access to food sources.

Evolve^® Rat was consistently consumed throughout the deployment, and over the six-month monitoring period, rodent activity across the surveyed area declined by 43%.

"My town has been wanting effective, long-term solutions to rodent issues, and I have hoped to get a humane method in use. I'm excited by the progress we've seen and how it's encouraged officials to expand to other areas in the community," said Deb Newman, president of Speak Up For Animals, a Swampscott-based advocacy organization.

Unlike traditional rodent control programs that focus primarily on reducing existing rodent populations, rodent birth control complements Integrated Pest Management practices by helping prevent future population growth while sanitation, exclusion, and habitat modification reduce the conditions that allow rodents to thrive.

"Communities across the country are recognizing that long-term rodent management requires more than simply reducing today's population," said Michael Edell, CEO of SenesTech. "When rodent birth control is combined with sanitation, habitat modification, and ongoing monitoring, municipalities can build more effective and sustainable rodent management programs. The Swampscott deployment demonstrates how Evolve^® Rat complements Integrated Pest Management strategies by helping reduce future population growth while supporting measurable improvements in rodent activity. As more municipalities evaluate long-term rodent management strategies, deployments like this illustrate how rodent birth control can strengthen existing Integrated Pest Management programs and support lasting population control."

The limits of rodenticide-first programs are drawing scrutiny in larger cities as well. Chicago was the subject of an Office of Inspector General review finding that, without addressing the underlying access to food, water and shelter, a new generation of rats fills the void left behind. SenesTech is seeing growing success in Chicago, where a groundswell of demand from residents and community organizations is driving interest in approaches that reduce reproductive capacity alongside sanitation and habitat improvements.

SenesTech continues to work with municipalities, pest management professionals, and public agencies to implement science-based Rodent Population Management programs that integrate assessment, monitoring, sanitation improvements, and rodent birth control to achieve long-term, sustainable results. The Swampscott deployment provides another example of how rodent birth control can complement traditional Integrated Pest Management practices by reducing the reproductive capacity of rodent populations while sanitation and habitat improvements address the environmental conditions that support infestations.
