The technology behind these mosquito misting systems was originally developed many years ago for use in barns to effectively protect horses and dairy animals from flying and biting insects. It was then only a simple step for an innovator and visionary to take the same idea and apply it for home use. Hence the beginning of the automatic insect control industry, the most effective and convenient method for eliminating biting insects in your yard. It also kills or repels other unwanted pests, like spiders, flies, gnats and no-see-ums.
