A multi-pallet restocking order for continued deployment and expansion is being placed

SURPRISE, Ariz. , June 25, 2025 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES, "SenesTech" or the "Company"), a leader in fertility control for managing animal pest populations, today announced the successful conclusion of a nine-month field trial of Evolve™ Rat Birth Control at the University Hills (UHills) residential community at the University of California, Irvine. The project was conducted in partnership with the Irvine Campus Housing Authority (ICHA) and reflects a growing commitment to ecologically responsible pest management.

The initiative began in September 2024 and marked the exclusive use of Evolve Rat Birth Control across common areas of the UHills community. This deployment was part of a broader effort driven by resident pressure on ICHA to transition away from rodenticides in favor of integrated pest management (IPM) strategies that prioritize environmental safety and wildlife preservation. Located adjacent to a wildlife reserve, the community's shift away from rodenticides further supports the protection of local wildlife and ecosystems.

"This project highlights how community-driven action and science-based solutions can work together to support sustainability," said Joel Fruendt, President and CEO of SenesTech. "Evolve aligns with these goals by providing a non-lethal, poison-free solution to rodent control."

Evolve was deployed across 267 bait stations previously containing rodenticides and snap traps. According to field observations, rats consumed 98% of Evolve across all stations each month, indicating high acceptance and performance of the bait. As expected, consumption dropped as the rat population dropped.

The field trial also supported the efforts of the HOOT Group (Help Our Owls Thrive), a grassroots initiative formed by UHills residents to promote owl nesting and reduce rodenticide use. Together, the partners implemented a range of actions, including installation of enclosed snap traps, removal of rodent harborage areas, and installation of barn owl nesting boxes to encourage natural predation.

"We've been encouraged by the strong bait uptake so far, and it's clear the community is energized about this shift toward more sustainable rodent control" said Andrew Herndon, Vice President of Community Development at ICHA. "It's rewarding to see residents actively supporting practices that are safer for people, pets, and the surrounding wildlife, and to see our efforts reflected by reduced rodent complaints and less observed rodent activity since launching Evolve."

As a result of the collaboration, rodenticides have been eliminated from all 267 bait stations across common areas in UHills. SenesTech is pleased to have contributed to this transition and to support communities like UHills and organizations like ICHA and HOOT that are leading the way in redefining effective, responsible rodent control.

A multi-pallet restocking order for continued deployment and expansion is being placed currently.
