Small Business Offers Innovative, Sustainable Methods of Rodent and Pest Control to Improve Human Health
Loretta Mayer, Ph.D.
As the global population and cities continue to grow, so do challenges in environmental control and management of chemical, physical, and biological factors that impact human health. For example, rodents present major public health issues in that they reduce the quality of life, destroy agricultural crops, and contaminate resources in protein production facilities. They also present a major burden as carriers of serious and often life-threatening disease agents that can be transmitted to humans. SenesTech is an innovative animal health company that offers novel, humane strategies to manage rodent and pest populations by targeting their ability to reproduce.
