A method of producing an insecticide spray for killing insects with droplets in the size range of from about 5 microns to about 15 microns. The spray consists of an insecticide, such as Naled-14, diluted with a nonvolatile liquid, such as cottonseed oil, in a ratio of 1 to 4 by volume. The aerosol generating equipment includes an engine driven blower supplying air at about 450 cubic feet per minute at a pressure of about 4 p.s.i. This air is supplied to a group of four air-liquid double vortical nozzles that atomizes the insecticide into the 5- to 15-micron size range.
