Mosquitos have been a malice and source of many diseases in humans. Later on, humans understood they learned that plants also possess mosquito-repellent properties. Different insectrepellent coatings are present in the market which are chemically prepared and can be harmful to humans and the environment. Different plants have insect-repellent properties which have been utilized in this research to make a nature-based insect-repellent surface coating.Moringa oleiferaL. andMentha piperitaL. are naturally insect-repellent plants. Nanoparticles increase the surface area and efficiency of extracts of plants. Thus, ZnONP ofMoringa olieferaL. andMentha piperitaL. plants were made characterization was done through UV-vis spectroscopy, FTIR, and PSA. The UV-visible spectrum showed absorption peaks for ZnO nanoparticles at 350nm forMentha piperitaL. and 356nm forMoringa oleiferaL. The particle size analysis indicated the variable sizes of ZnONPs for both plants. FTIR showed vibration peaks from 3341 to 650cm-1forMoringa oleiferaL. and 3393 to 700 cm-1forMentha piperitaL. ZnONPs were used in paint along with water extracts of plants to make the paint insect-repellent in nature. Mosquito repellent activity of paint formulations was also tested againstAedes aegypti.
