SenesTech, Inc. has developed and is in the process of commercializing a proprietary technology for managing animal pest populations, primarily rat populations, through fertility control.


About ContraPest

ContraPest® is an innovative technology that targets the reproductive capabilities of Norway and roof rats. As a highly palatable liquid, the formulation promotes sustained consumption, helping to reduce fertility in both male and female rats, bringing populations down and keeping them down. Our delivery system is designed to minimize handler exposure, and ContraPest is dispensed inside tamper resistant bait stations, minimizing the risks to non-target species.

As a versatile tool, ContraPest can be used within Integrated Pest Management (IPM) programs to help reduce reproduction and magnify the success of IPM protocols or as a standalone, non-lethal solution for customers that are looking to reduce or eliminate the use of lethal methodologies.

ContraPest® is registered federally as a General Use Product when used as directed. However, in some states, due to applicator expertise, it is a Restricted Use Product. Please check with your local state regulatory agency to determine restriction status. Read and follow all label instructions for target species Norway and roof rats.
