The B. David Mosquito Nets are certified for either field or domestic use, manufactured with a specialized insecticide application that offers the best, most comprehensive protection from the Zika virus, Leishmaniasis, Yellow Fever, Malaria, Encephalitis, etc. Our nets are made from a proprietary multifilament thread, which allows them to last at least three-times longer than other conventional store bought nets – minimizing replacement and maximizing investment. Shipments can be sent domestically or to most any international location.
