Deer Repellent With Odor Mode of Action

Deer repellent that focuses on adding an odor that deer will stay away from can be a part of a mullti-facet program.  Milorganite adds a bonus if you are also treating the lawn with fertilization and weed control.  It will encourage growth and the iron will improve the color while deterring the deer.  It is commonly used in fruit orchards for thiss purpose.

Milorganite is a processed sewage sludge that originates from Milwaukee. Sewage sledges are residue of organic matter generated as a byproduct of waste water treatment.  After waste water treatment, the water is removed and the waste is heated and dried, then made into small granules.

 The heating process kills viral and bacterial pathogens. The trade name Milorganite was derived from MILORGANITE.  This treated sludge is sold as a natural fertilizer with a formulation of 6-2-0 (N-P-K).

According to its material safety data sheet Milorganite is "registered for sale in all 50 states and meets all federal and state requirements.  The United States Department of Agriculture (USDA) certifies it as biobased because it is derived from 85% renewable materials.  It is not, however, certified for use on USDA organic farms.
