The Use of Microdispensers with Spatial Repellents for Personal Protection Against Mosquito Biting

Abstract Mosquito-borne pathogens affect millions of people worldwide. This work describes a new method to deliver spatial repellents. Functional microdispensers (FMDs) were designed to deliver spatial repellents against mosquitoes. In vivo trials showed that FMDs protect human subjects against mosquitoes by reducing 70–90% of bites received, with a protection that lasted up to 4 weeks. FMDs can be cost-effectively implemented as wearable or field-dispensed devices for local area protection, defined as a confined geographical region.
