Spatial repellents in the US military: scenarios across multiple environments targeting mosquitoes, sand flies, and tabanids

There is an increasing need for new vector control agents by military and civilian populations which is made more acute by the widespread resistance to pyrethroids in important mosquito species. Spatial repellents such as transfluthrin provide an alternative to standard repellents and standard toxicants. We conducted studies across a variety of ecological regions to investigate the capabilities of spatial repellents such as transfluthrin applied as a residual on US military materials, applied as a space spray, and emanated from heated and passive diffusers at reducing incursion into protected spaces by disease vector and nuisance mosquitoes, sand flies, and tabards. We found that spatial repellents may substantially reduce collections of nuisance and disease vector insect targets but that efficacy varies by environment, target insect, substrate, and other key factors. Transfluthrin and other spatial repellents hold great promise to contribute significantly to both civilian and military integrated vector management systems.
