Storage and Disposal

Quick Tips:

1. Sweep leftover Milorganite into a container or back into your lawn or landscape
2. Milorganite has no expiration date
3. Store in a cool, dry, area out of the reach of children and animals

While Milorganite is a safe product, there are some considerations to keep in mind during storage and disposal.


Sweep, vacuum or shovel spilled or leftover material into a labeled container.  Please keep the material from getting into any bodies of water.  Reuse the product as a fertilizer for all of your landscaping and gardening needs by following the application directions on the packaging. 

Milorganite has no expiration date.  It will work indefinitely if stored properly in a cool, dry area out of the reach of children and animals.

Some dogs may be attracted to the smell of Milorganite and try to eat it.  Store Milorganite in a sturdy container or in an unreachable location.  If your dog eats Milorganite, there are no long-term toxic effects.  Short-term indigestion can occur for up to 24-48 hours with a full recovery generally by the third day.  For more information visit our FAQ page.
