San Francisco Recreation & Parks Department Achieves Success with ContraPest and Expands Deployment in 2020

PHOENIX, Aug. 12, 2020 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), a developer of proprietary technologies for managing animal pest populations through fertility control, today announced that San Francisco Recreation and Parks Department has achieved success by adding ContraPest® to their Integrated Pest Mangement (IPM) programs in 2019 and has expanded use in 2020. 

"Our department has a mission to preserve the environment and we must stick to this mission when dealing with rodent control," said Zachary Goetschi, San Francisco Recreation and Parks IPM Specialist. "To support our goal of reducing reliance on traditional rodenticides, we began using ContraPest in the summer of 2019. Within a few months we did see positive results in conjunction with other environmentally conscious IPM methods. We are excited with the outcome and are happy to have an alternative to rodenticides to add to our toolbox."

"San Francisco Recreation and Parks Department achieved a 65% reduction in burrow counts at a site while using ContraPest within their IPM program," said Kenneth Siegel, SenesTech's CEO. "Managing rodent populations is a challenge when dealing with multiple, diverse habitats. San Francisco Recreation and Parks Department manages more than 220 parks, open spaces and additional recreational areas. We are pleased that the integrated deployment of non-lethal ContraPest significantly reduced rat populations through fertility management  without unintended consequences to the environment or non-target populations.  This collaborative effort between San Francisco Recreation and Parks Department and SenesTech is an example for other communities faced with significant rat populations that success can be achieved through collaboration." 

About SenesTech 

SenesTech is changing the model for pest management by targeting one of the root causes of the problem: reproduction.

ContraPest® is an innovative technology with an approach that targets the reproductive capabilities of both sexes in rat populations, inducing egg loss in female rats and impairing sperm development in males. Using a proprietary bait delivery method, ContraPest® is dispensed in a highly palatable liquid formulation that promotes sustained consumption by rat communities. ContraPest® is designed, formulated and dispensed to be low hazard for handlers and non-target species such as wildlife, livestock and pets, where the active ingredients break down rapidly.

We believe ContraPest® will establish a new paradigm in rodent control, resulting in a decreased reliance on lethal options. For more information visit the SenesTech website at
