There’s a lot to
learn about rats

With our background in science, it’s no secret that knowledge is our greatest tool. We invented ContraPest because we learned about rodent pest populations and studied their biology. What rats eat, where they nest, their size, shape, color, their mating habits; in the world of pest control, all this information is key.

The Rebound Effect

Traditional pest control tools are reactive: they eliminate rats quickly when populations boom. However, without fertility control, it only takes two rats to initiate a rebound, growing the population back to its original size or larger within a matter of months. Under the right circumstances, a rodent population may never be fully controlled with lethal methods alone.

The secret ingredient(s)

ContraPest has two active ingredients: 4-vinylcyclohexene diepoxide (VCD) and triptolide.

Triptolide, derived from the thunder god vine Tripterygium wilfordii, has been used in traditional Chinese medicines and other over-the-counter supplements. Triptolide affects the reproductive capacity of both male and female rats. VCD is an occupational chemical that selectively destroys ovarian follicles in rats.
