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.

There are many tools available to combat rodent infestations. Unfortunately, pest management professionals still find themselves at a disadvantage – rats reproduce at an extremely rapid rate. As a fertility control solution, ContraPest provides the missing link within your IPM program.

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 and comply with the label instructions. ContraPest® is a Restricted Use Pesticide, due to applicator expertise.

ContraPest: How It’s Delivered & Safety

ContraPest® is a liquid rodent fertility control bait that helps you tackle persistent rodent infestations with unprecedented success.

ContraPest is an innovative technology that targets the reproductive capabilities of Norway and roof rats. By reducing reproduction, ContraPest can be the anchor to your Integrated Pest Management (IPM) program and magnify the success of your IPM methodologies.

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