FAQs

Milorganite® is composed of heat-dried microbes that have digested the organic material in wastewater. It's manufactured by the Milwaukee Metropolitan Sewerage District, which captures waste water from the metropolitan Milwaukee area and uses naturally occurring microbes to digest the nutrients. After the organic matter has been consumed, the cleaned water is returned to Lake Michigan and the resulting material is dried and marketed as Milorganite®.

Milorganite® complies with federal and state standards for the protection of public health and the environment. Milorganite® can be used with confidence for all of your fertilizing needs, including lawns, trees, shrubs, flowers, and vegetables when used as directed. For more information visit our safety page.

First off, there’s no need to panic if your dog happens to eat Milorganite® either off your lawn, garden or even directly out of the bag. It isn’t life-threatening or an emergency situation. Your dog may experience discomfort and outcomes you would expect when a dog eats something they shouldn’t. We recommend contacting your veterinary for advice. We have a few pet safety tips to help deter your dog’s urge to taste-test Milorganite®.
