SenesTech and Pestmaster Announce ContraPest® Deployment in Southern California Transit Agency

FLAGSTAFF, Ariz. and RENO, Nev., March 6, 2019 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), a developer of proprietary technologies for managing animal pest populations through fertility control, and Pestmaster Services (Pestmaster), a pest control industry leader and one of the leading authorities on Integrated Pest Management (IPM) solutions, announced today deployment of ContraPest® in a major transit agency in Southern California.

SenesTech, Inc. has developed an innovative technology for managing animal pest populations through fertility control as opposed to a lethal approach.

Pestmaster, who has an IPM contract with the large Southern California metropolitan transit agency, had previously submitted ContraPest for the agency's approval. The approval to deploy ContraPest was received on February 27. Pestmaster will move immediately for an initial deployment, and continue to deploy as needed within the guidelines of their IPM program.

"ContraPest is an integral part of our IPM strategy," said Jeff Van Diepen, founder and CEO of Pestmaster. "With this approval and deployment, we can now expand our use of ContraPest to other, similar agencies."

"Rat control challenges in California have been in the news lately, with numerous reports of rat infestations and related problems that are not responding to traditional methods. IPM that includes fertility control may well be the answer to those challenges," said Dr. Loretta Mayer, CEO and co-founder of SenesTech. "As with Washington D.C., bringing a new approach to a century's old problem requires the commitment and vision of an entire community.  We look forward to working with Pestmaster, and forward-looking communities in achieving that vision of a safe and sustainable environment."

About SenesTech 

SenesTech is changing the paradigm of pest management by targeting the root cause 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
