The inspiration for Orange Guard came from McPartland's desire to find an alternative to these insecticides which have the potential of long-term health and environmental dangers. In 1984, McPartland read an article in Science News, where someone had taken citrus hand cleaner and poured it down a fire ant hill. Every ant was killed.
Orange peel is a natural repellent.
Starting in 1985, McPartland spent the next 14 years in research and development efforts, including extensive testing and certification for safety and effectiveness. In May 1998, McPartland introduced his first product to consumers.
