Left unchecked, two base rats, a male and a female, can result in 15,000 descendants in about 12 months. It’s easy to see how quickly this can lead to infestations and even population rebounds if just two rats are left behind after a knockdown program. That’s where we come in. We’re SenesTech, the rat fertility experts and the makers of ContraPest®, the first and only EPA-registered rat fertility restrictor impacting both male and female rats. We make it possible to target both ends of the lifecycle—birth and death—by adding fertility control to your integrated pest management (IPM) solution. Controlling the birth rate with ContraPest will magnify the success of your existing IPM protocols. ContraPest is the one-of-a-kind, innovative technology that targets the reproductive capabilities of both male and female Norway and roof rats. Sweet and fatty, it’s highly palatable like a “milkshake” rats can’t get enough of. By using ContraPest, you can reduce the rat population and keep it down because ContraPest works!
