Our technology

Unique technology and patent portfolio

We have developed and patented species-specific technology for managing animal pest populations by targeting fertility.

The active ingredients in ContraPest chemically accelerate the depletion of eggs in female rats and cause testicular disruption in male rats. After ingesting the bait, rats become infertile. The technology has been refined and optimized to achieve follicle depletion and testis disruption without causing systemic toxicity or adverse side effects. Studies indicate that when used as directed the formulation is environmentally neutral, and will not affect the food chain.

No effect on non-target species

In laboratory studies, it has been shown that rats rapidly metabolize our active ingredients. Additionally, the half-life of our active ingredients in the blood is less than 15 minutes in rodents. This data confirms that non-target species that consume rodents that have eaten our product will have no secondary effects.

No effect on humans

At the concentrations of active ingredients in our product there is no potential for reproductive disruption in humans.

Environmental neutrality

The man-made active ingredient is rapidly broken down in water so there is no accumulation risk. The plant-derived ingredient in our product is an extremely low concentration and consequently poses no accumulation risk.
