The use of synthetic, chemical insecticides for vector control has certainly been and still is important in the protection of human disease prevention from arthropods. However, there are also challenges because of resistance, the need to develop new chemistry to circumvent resistance, and the cost of bringing new compounds to the vector control market. Vector control alone often is unable to support the investment needed to register a new insecticide. Also, there is a growing interest in the use of natural products that really work. Maybe there are non-chemical approaches to vector control, and what is old could be new again. Our team has been studying the use of industrial minerals for mosquito, filth fly and sand fly control. One success has been the discovery of volcanic glass as a residual wall spray. For example, in Phase II field trials in experimental huts in Africa, we found six months of protection by WHO standards against pyrethroid-resistant, malaria mosquitoes. The active is applied with standard spray equipment, mixes easily in water, has no re-entry restrictions after application, and is not subject to thermal degradation. You will be surprised about your everyday use of this mineral. We will discuss exciting additional applications of this technology and other minerals for mosquitoes, filth flies and sand flies.
