SenesTech, Inc. has developed a proprietary technology for managing animal pest populations, primarily rats, 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 risk to non-target species.

ContraPest can be used as part of an integrated pest management (IPM) program to help reduce reproduction and magnify the success of IPM protocols or as a standalone solution for customers who want to reduce or eliminate the use of lethal methods.

ContraPest® is registered federally as a General Use Product but requires an RUP license if being deployed in: Connecticut and New York. Due to conditional registration status in California, the product is not allowed to be used in public schools or childcare facilities within the state of California at this time. ContraPest is intended for professional use only. Read and follow all label instructions for target species Norway and roof rats.
