California's AB1788 Passed by Legislature and Sent To The Governor
ContraPest® Positioned to Support Integrated Pest Management

PHOENIX, Sept. 2, 2020 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), a developer of proprietary technologies for managing animal pest populations through fertility control, today confirmed that California's AB1788 has been passed by the California Legislature and is being sent to the Governor for signature.  

California is poised to create the California Ecosystems Protection Act of 2020 (the Bill), which would prohibit the use of the four major Second Generation Anticoagulant Rodenticides (SGARs) commonly used in rodent pest control under many circumstances.  While the Bill is intended to address the vulnerability of wildlife to the lethality and ecologic persistence of these SGARs used for rodent control, it also creates a challenge to pest management professionals (PMPs) who incorporate SGARs in their integrated pest management (IPM) programs. Absent the use of these SGARs, pest management will have to rely on other lethal and non-lethal tools, such as fertility control.

"ContraPest® has been proven to increase the effectiveness of IPM programs in diverse environments such as San Francisco parks and neighborhoods, Washington D.C. urban areas, California animal shelters, and a number of California agricultural settings. This positions ContraPest as a potentially crucial addition to all IPM programs," said Kenneth Siegel, SenesTech's CEO.  

"California has always been at the forefront of sustainable innovation in pest control, and I have no doubt that the industry will adapt quickly and effectively to this latest change. We will be working with California's PMPs to see how we can best support their IPM efforts in this new regulatory environment," said Dr. Steven Krause, SenesTech's EVP of Sales and Marketing. "It is clear to me that other states will be watching closely to California's lead, and will move to adopt similar, proven innovations."

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
