A New Tool for your IPM Toolkit

Senestech introduces ContraPest®, a non-lethal solution for your Integrated Pest Management program

Changing the paradigm: Our technology targets the root cause of the problem: reproduction.

The incredible speed at which rats reproduce and multiply is astounding. Two mating rats can, under ideal conditions, be responsible for 15 thousand descendants over the course of year. Senestech believes ContraPest® will establish a new paradigm in rodent control, by targeting the root cause of escalating rat populations: reproduction.

ContraPest®: How it works

Senestech introduces ContraPest®, a proven technology aimed at providing a non-lethal, rodent fertility control solution that can be utilized across diverse settings to help pest management professionals, like you, solve even your most difficult rat infestations.

As an innovative technology, ContraPest® targets the reproductive capabilities of both sexes in rat populations, inducing egg loss in female rats and impairing sperm development in males.  Using a proprietary bait delivery method, the bait is dispensed in a highly palatable liquid formulation that promotes sustained consumption by rat communities.

ContraPest® is delivered in a JT Eaton Rat Fortress (903TP) Bait station and is approved for Norway and roof rats. *Please read, understand and comply with the label instructions. ContraPest® is a Restricted Use Pesticide.

ContraPest®: How It’s Delivered & Safety

ContraPest® is designed, formulated and dispensed to be low hazard for handlers and non-target species such as wildlife, livestock and pets, where the active ingredients break down rapidly.

Delivered in tamper-resistant JT Eaton Rat Fortress (903TP) bait stations, ContraPest® must be deployed by a licensed Pest Management Professional. Each bait station houses two inserts that dispense 550mL each, for a total of 1.1L per station.

ContraPest® can be used as an anchor for an integrated pest management program, or as a stand-alone solution to decrease reliance on lethal options.

*Please read, understand and comply with the label instructions. ContraPest® is a Restricted Use Pesticide.
