The bear repellent composition includes onions that have been frozen, subsequently thawed, and allowed to rot for an extended period, such that the onions liquefy. A method of making the bear repellent composition includes inserting a plurality of onions into a first container, maintaining the first container at a temperature of less than zero degrees Celsius for at least seventy-two hours, thawing the frozen onions and transferring them to a second container, shaking the second container until the contents are liquefied, and transferring the contents to third container for four to six months, and subsequently agitating the third container for a half hour once every three or four days. The composition can then be left outside, or may be placed in a spray bottle and sprayed outside to deter bears.
