About SenesTech

Managing animal populations humanely and effectively by targeting the key issue: reproduction

Founded by two scientists with a deep love for animals, SenesTech is a platform biotechnology and research company that has developed an innovative method for managing animal populations by fertility control. We develop non-lethal treatments that have the potential to be more effective, more humane, and less invasive to the environment than traditional management methods.

Novel solutions to age-old problems

SenesTech’s first product ContraPest, applies our revolutionary technology to a worldwide problem that has persisted since the Middle Ages: the proliferation of rats in both urban and agricultural settings. ContraPest is readily consumed by rats and leaves them infertile with no other observable side effects. The rodents live out their normal life span without producing offspring. Since rapid reproduction is the root cause of rat infestations, ContraPest introduces a new paradigm to the science of pest control.

When used as directed, our species-specific formulation is environmentally neutral, does not affect non-target animals, and has no impact on human health or fertility.

EPA registration and commercialization

We received EPA registration in 2016 and are currently registered in 49 states. We are awaiting approval in California.

The science behind ContraPest is well established and shows early promise for the humane control of other pest species from deer to wild pigs. Long-term, there is potential for a SenesTech formulation to become a non-surgical solution for the spaying and neutering of feral cats and dogs.
