ContraPest® is THE Answer to the Recommendation by the California Department of Fish and Wildlife Alert as AB 1788 Clears Critical Hurdle

FLAGSTAFF, Ariz., April 15, 2019 /PRNewswire/ -- SenesTech, Inc. (NASDAQ: SNES), a developer of proprietary technologies for managing animal pest populations through fertility control, provides a long term solution within the state of California specifically in response to the recommendation by California Department of Fish and Wildlife: i.e. "CDFW Issues Reminder to Avoid Harmful Poisons." 

SenesTech, Inc. has developed an innovative technology for managing animal pest populations through fertility control as opposed to a lethal approach. The Company's first fertility control product, ContraPest(R), is marketed for use initially in controlling rat infestations. (PRNewsfoto/SenesTech, Inc.) (PRNewsfoto/SenesTech, Inc.)

On April 11, 2019, the CDFW published in the California Fish and Wildlife News ( that with the increased precipitation experienced in California rodent populations are increasing, and in addition to the increased rodent population growth, "…CDFW reminds people that rodenticides can also kill non-target wildlife, and even pets and children." This alert comes only days after AB1788 (the Bill that would create the California Ecosystems Protection Act of 2019 and, in short, prohibit the use of the four major Second Generation Anticoagulant Rodenticides (SGARs) commonly used in rodent pest control) passed the Assembly Water, Parks and Wildlife committee with a vote of 8 Ayes, 5 Noes. The Bill is currently before the Appropriations Committee. 

"California's economy of $2.7 trillion is a prime factor in our decision to concentrate our resources and effort here on behalf of our flagship product - ContraPest®. Realizing that California, by itself, is the fifth largest economy in the World validates our commercial decision to focus our efforts here in an attempt to accelerate the proliferation of ContraPest sales in California," said Edward Albe, Senior Vice President of Commercialization. "We are anxious, on behalf of California's concerned populace, to answer their desire for new, and better, wildlife management tools. In alignment with California's integrated pest management professionals, we are concerned with balancing rodent control with the protection of non-target wildlife species, and provide an effective non-lethal tool for rodent management. ContraPest is indeed a compelling value-add for all stakeholders who share our vision!"

"SenesTech developed ContraPest as a liquid because rats require 10% of their body weight daily in water for survival," said Dr. Loretta Mayer, CEO and co-founder of SenesTech. Dr. Mayer further states that "unlike mice who get adequate hydration from the food they eat, the changing climate means that increasing precipitation in many regions will provide an endless fountain of water for the rats, and dense vegetation undergrowth for habitat. This is the perfect storm in creating ideal conditions for rats to breed. Let's get out ahead of the root cause of the problem that's on it's way…we must blunt reproduction with fertility control."

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
