SenesTech: Evolve Field Trials Show 50–79% Decline in Urban Rodent Activity

Urban Field Trials Show Steep Decline in Rodent Activity After Evolve Deployment

SenesTech reports that multi-month deployments of its Evolve® Rodent Birth Control produce substantial declines in urban rodent activity across two monitored sites, based on a five-month tracking-plate study carried out between August 2025 and January 2026. At Location A, where deployment began in April 2025, the proportion of tracking plates showing rodent presence falls from an average of 74% in August 2025 to 15% in January 2026, a 79% reduction, while track density on plates with activity drops by 88%. At Location B, which has a pre-deployment baseline, plate presence is 98% before placement in August 2025 and 47% after five months of baiting in January 2026, representing just over a 50% reduction accompanied by a 71% decline in track density.

The study uses standardized tracking plates at regular intervals to measure both the proportion of plates with rodent tracks and the relative density of markings, and SenesTech says the results reflect real-world urban conditions. The company notes that Location A lacks pre-deployment baseline data prior to April 2025 but emphasizes that both sites show measurable declines in the prevalence and intensity of rodent activity within five months of Evolve deployment. The findings are set out in a Feb. 18, 2026 PRNewswire release from Surprise, Arizona.

SenesTech frames the results as evidence that fertility control can reduce rodent populations where the bait is consumed and reproduction decreases. Joel Fruendt, SenesTech president and chief executive, says structured field studies and objective data help municipalities and pest management professionals evaluate fertility control within integrated pest management programs, concluding that “Evolve Rodent Birth Control works.” The company highlights the combination of laboratory and field evidence supporting bait uptake and subsequent population declines.

Study Limitations and Operational Notes

SenesTech acknowledges the limitation of missing a pre-deployment baseline at one site and presents the data as location-specific field observations rather than a broad efficacy claim. The company says objective field measurements can guide decisions on additional deployments and scaling to new locations.

Implications for Municipal Pest Programs

SenesTech positions the Evolve data as a tool for municipalities and pest management professionals considering fertility control as part of integrated pest management, arguing the approach can help communities reduce local rodent damage while informing operational choices on deployment timing and coverage.
