Metofluthrin, 2, 3, 5, 6-tetrafluoro-4-(methoxymethyl)benzyl(EZ)-(1RS, 3RS;1RS, 3SR)-2, 2-dimethyl-3-prop-1-enyl cyclopropanecarboxylate possesses a relatively high vapour pressure coefficient under ambient conditions, and, therefore is amenable to self-diffusion. The metofluthrin impregnated substrates have therefore the potential to function as slow release formats for providing long lasting mosquito protection. Based on the release data generated using chromatographic and thermo analytical measurement tools, this study reports metofluthrin’ s relative release from various impregnated substrates under ambient conditions. The release of metofluthrin after 120 hours from various substrates followed the order: nylon > cellulose ~ poly-(ethylene) terephthalate > poly-(propylene). Its quickest release under equilibrium conditions also followed the initial release pattern, i.e. nylon closely followed by cellulose, poly-(ethylene) terephthalate and poly-(propylene) respectively.
