+Added: Rodents pose threats to human and animal health, food security and infrastructure around the world, and humanity has spent centuries trying to mitigate the problems associated with these pests.
+Added: Rodents are known to be reservoir hosts for at least 60 zoonotic diseases and the potential transmission of these diseases creates a global risk to public health and safety, as well as agriculture, affecting crops, livestock, stored grain, and farm workers.
+Added: Diseases such as leptospirosis and salmonellosis directly impact reproductive efficiency in livestock, contaminate feed supplies, and increase liability exposure for agricultural operators.
Through consumption and contamination, rats destroy at least 20% of the global stored food supply every year.
Additionally, rats cause over $27 billion in damage to public and private infrastructure annually in the United States alone by burrowing beneath foundations and gnawing on electrical wiring, insulation, fire-proofing systems and equipment.
−Removed: Over the centuries, the most prevalent response to rodent infestations has been an attempt to eliminate them through the use of lethal tools such as traps and rodenticides.
−Removed: However, there are growing concerns about the environmental and ecological impact of rodenticides due to secondary exposure and bioaccumulation, including a push for safer and more humane products as consumer awareness increases.
−Removed: While some of these challenges are of recent concern, the efficacy of how rodent infestations respond has always been limited by their extraordinary reproductive rate.
−Removed: ContraPest, our initial product, is a liquid bait, containing the active ingredients 4-vinylcyclohexene diepoxide (“VCD”) and triptolide.
−Removed: ContraPest targets the reproductive systems of both male and female rats, is a highly palatable formulation, does not cause illness or changed behavior in rats, and leads to significant reductions in fertility and rat populations.
−Removed: Accordingly, ContraPest is an additional tool to use as part of an IPM program.
−Removed: On August 2, 2016, the EPA granted an unconditional registration for ContraPest as a Restricted Use Product (“RUP”), requiring purchase or application oversight by a licensed professional.

−Removed: The Evolve product line, which began in the form of Evolve Rat, launched in January 2024, and is currently our lead product.
+Added: Compounding the problem, rats reproduce rapidly.
+Added: Even intensive lethal control efforts are often undermined by rapid population rebound, fueled by high fecundity, early sexual maturity, and density-dependent compensation.
+Added: Furthermore, urbanization, climate variability, and aging infrastructure are contributing to accelerated rodent population growth and heightened infestation pressures globally, including major metropolitan areas, thereby increasing associated economic costs and public health risks.
+Added: For centuries, the dominant response to rodent infestations has been eradication through lethal means—primarily traps and rodenticides.
+Added: Yet this approach is increasingly under scrutiny.
+Added: Mounting evidence of non-target secondary poisoning and bioaccumulation has heightened environmental and regulatory concerns, driving demand for ecologically-friendly alternatives as public awareness grows.
+Added: While ecological risks have come into sharper focus in recent years, a fundamental limitation of lethal management is rodents’ extraordinary reproductive capacity.
+Added: Traditional eradication strategies frequently provide only temporary suppression rather than long-term population control, perpetuating a costly cycle of reinfestation.
+Added: The Evolve product line launched in January 2024 as Evolve Rat and is currently our primary revenue-generating product.

This prolific breeding can cause populations to rebound quickly even after implementing a lethal control program.
+Added: Traditional lethal control methods and fertility control approaches operate through fundamentally different mechanisms and may present different risk profiles, timelines, and regulatory considerations.
+Added: The relative effectiveness of any approach depends on environmental conditions, population dynamics, and implementation practices.
+Added: Lethal control measure such as traps and rodenticides are often at the forefront of rat control programs.
+Added: Published ecological research indicates that lethal population control measure may be followed by compensatory reproductive responses.
+Added: These responses can include earlier sexual maturity, increased litter sizes, higher breeding frequency, and recolonization from surrounding areas.
+Added: This phenomenon, often described as density-dependent reproduction, has been documented in wildlife and population ecology literature.
+Added: The extent to which such efforts occur can vary based on species, environmental conditions, and management practices.
Rodent behavior, either learned or innate, can negatively affect pest control efforts.

−Removed: Rodents, like all animals, are hard-wired to survive.
−Removed: Further, some rats can be born with a genetic mutation making them resistant to certain rodenticides.
−Removed: Studies show that resistance is increasing in commensal rodents as resistance can be passed onto offspring who will then carry this resistant trait into future generations.
+Added: Some rats can be born with a genetic mutation making them resistant to certain rodenticides due to prolonged use of anticoagulants in rodent management.
+Added: Multiple published studies have documented increasing resistance in certain rodent populations to both first-generation and second-generation anticoagulant rodenticides.
+Added: Such resistance can reduce product efficacy and, in some cases, may contribute to prolonged control efforts, increased risk of secondary exposure to non-target species, and heightened regulatory scrutiny.
+Added: Fertility control products operate through a non-lethal mechanism of action and therefore are not subject to anticoagulant resistance dynamics.
+Added: Studies show that resistance is increasing in commensal rodents as the gene can be passed onto offspring who will then carry this resistant trait into future generations.
Because of these factors, traditional rodenticide producers are continually challenged to develop new, more lethal chemicals to control future rat populations.
