FREQUENTLY ASKED QUESTIONS
Below are some of our most frequently asked questions about ContraPest from our customers. If your question isn’t here, please don’t hesitate to contact our team. We’re happy to answer any questions you have!
Collapsible content
What are the active ingredients in ContraPest?
The active ingredients in ContraPest are:
• 4-Vinylcyclohexene diepoxide (0.09604%)
• Triptolide (0.00118%)
How quickly does ContraPest work and for how long?
ContraPest provides a cumulative effect, thus the more a rat consumes, the greater the result. However, it may take several months before a significant decrease in population size is noticeable. ContraPest is a contraceptive, not a sterilant, so a continuous supply maintains reduced populations.
Where can ContraPest be used?
ContraPest can be used in a variety of settings. Please read and follow label instructions for deployment.
ContraPest is registered for indoor, non-food use and within 1 foot around external perimeters of man-made structures.
Do not place bait stations where they are likely to become submerged or inundated with water or on an uneven surface. To avoid damage to the bait station, do not use bait stations in areas open to hoofed livestock or potentially destructive wildlife.
When should I change the bait and how often does the bait station need to be serviced?
Please read and follow label instructions for ContraPest. ContraPest must be replaced every 30 days. If tanks are empty, replace tanks prior to 30 days.
For optimal convenience, subscribe to ContraPest for a monthly delivery of product straight to your door.
What is the shelf life of ContraPest?
In the initial submission for EPA registration, the shelf life component was waived/deferred with the understanding that this information would be provided at a later date. However, we are currently working on providing the EPA with data and documentation to calculate shelf life as part of our continuous label improvement efforts.
Is ContraPest a restricted use product?
ContraPest® is registered with the US EPA as a General Use Product when used as directed. However, ContraPest continues to be a Restricted Use Product (RUP) in New York and Connecticut. ContraPest is General Use in California but continues to follow and observe the Healthy Schools Act and restrict the use of our product around school sites as identified in this regulation. Please always read and follow all label instructions for target species of Norway and roof rats.

Research studies
ContraPest®
Lethal rodenticides and other lethal tools of managing commensal rodent populations long-term are not sustainable due to population rebounds and increasing resistance to rodenticides. The use of integrated pest management (IPM) programs are more prevalent due to consumer desire to decrease rodenticide use and utilize environmentally friendly, humane methods. IPM plans often require multiple tools to control an infestation, such as physical, biological and chemical measures. Here, we propose that rodent population management would benefit from a new tool aimed at targeting the biological source of overabundance: reproduction. SenesTech, Inc. (Flagstaff, AZ USA) has developed ContraPest, a liquid bait that limits the reproductive capacity of both male and female wild Norway and Roof rats.
