A rodent-repelling composition in accordance with the present invention formed by combining an amount of diatomaceous earth, preferably food grade, with a small amount of water and a chamomile element, e.g., a few drops of chamomile essential oil. Potency of the composition can be increased by the addition of a small amount of finely-divided, i.e., ground, chamomile. Either German or wild chamomile (Matricaria recutita) or Roman, English, or garden chamomile (Chamaemelum nobile) are suitable. In a method for using the above rodent-repelling composition, the composition is placed in an area known or believed to be inhabited or trafficked by rodents. Alternatively, the composition may be placed directly in rodent runs or nests.
