This insecticide uses the same principle as planting chives or scallions next to insect-prone plants. The spray works well on roses and is especially safe and effective on garden vegetables where chemicals are unwanted. For use on indoor plants, dilute it with equal amounts of water and use sparingly.
Peel and coarsely chop onions and garlic. Pack into a 2c glass jar. Pour in enough water to reach the top of the jar. Cover jar tightly and let it steep in a dark place at room temperature for 1 WEEK. Strain liquid into a small spray bottle and mist liberally over any outdoor plants where there is an insect problem.
