More than a product – a layered strategy

Building upon more than 20 years of research, Valent BioSciences in partnership with other public health organizations have developed the most target-specific biorational solution for controlling mosquito larvae in difficult-to-find and/or access habitats. And with the increasing potential of vector-borne disease outbreaks from container mosquitoes threatening larger segments of our population, there’s never been a greater need for WALS to help public health professionals meet their Integrated Vector Management (IVM) goals.
