ContraPest® Under the St. Louis Arch, Gateway to the West!

FLAGSTAFF, Ariz., March 18, 2019 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), a developer of proprietary technologies for managing animal pest populations through fertility control, confirmed news reports that the City's Gateway Arch Park Foundation will continue and expand their use of ContraPest as the City of St. Louis embraces the role fertility control plays in integrated pest management.

"While onsite this past Friday, March 15th, I was pleased to provide comments to KMOV (a CBS affiliate) in St. Louis for a special piece on our success in rat management with ContraPest in the City. SenesTech has been dedicated to urban rodent issues since our very first trial," said Brandy Pyzyna, Vice President of Scientific Operations of SenesTech.

The St. Louis metropolitan area is a major inland port and home to approximately 3 million people. The city is well know for aggressively addressing urban problems, such as air pollution in the first part of the 20th century. In 2006 St. Louis won the World Leadership Award for urban renewal. "It is no surprise that St. Louis continues their commitment to excellence in city management and choosing ContraPest is yet another step forward into the future. We are proud to be a part of their thoughtful leadership," said Dr. Loretta Mayer, CEO of SenesTech, "and yes, their vision from the top of the Arch."

"Perhaps more is known about urban rats by the pest management industry as a whole, however, the role of fertility control is novel and actually accelerated in such areas where food, water, and shelter are in abundance. The complete integrated approach to reducing rodent pests is dependent on working together with communities that are dedicated to providing that sound science to our industry colleagues," said Terry Hoselton, owner of Missouri Pest Consultants (MPC) and project manager of the St. Louis deployment. "The City has further expanded the use of ContraPest into other structures throughout the city."

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
