The short answer
Safety First
Human waste can carry bacteria and viruses that make you sick. Before you start, put on disposable gloves, a mask, and old clothes you can wash or throw away. Work in a well-ventilated area, and avoid touching your face. If you feel unwell during or after the cleanup, see a doctor.
Keep children and pets away from the area until the cleanup is complete. Wash your hands thoroughly with soap and water after removing your gloves. If the waste is near a water source, like a well or a garden, be extra cautious. Contaminated water can spread illness.
- Wear gloves and a mask
- Use a shovel, not your hands
- Double-bag the waste
- Wash tools and hands after
- Keep pets and kids away
Removing the Waste
Use a shovel or a scoop to lift the waste into a sturdy plastic bag. Tie the bag closed, then place it inside a second bag and tie that one too. This double-bagging reduces the risk of leaks. Put the bag in your outdoor trash bin for regular pickup.
If the waste is on grass or soil, you may need to remove a thin layer of the contaminated surface. A shovel can scrape away the top inch or so. Dispose of that material the same way. Avoid using a hose to wash the waste away, as that can spread contamination.
Cleaning the Area
After the waste is gone, clean the spot with a disinfectant. A solution of one part bleach to nine parts water works well for hard surfaces like concrete or stone. For soil or grass, you can use a commercial enzyme cleaner designed for pet waste, which breaks down organic matter.
Let the disinfectant sit for at least five minutes, then rinse with water if the surface allows. For porous surfaces like wood or mulch, you may need to replace the material entirely. If the area has been contaminated for a while, consider testing the soil before planting anything there.
When Water Damage Is Involved
If human waste has mixed with standing water, such as from a sewage backup or a flood, the situation is more serious. The water may carry pathogens that can soak into your yard and nearby structures. Do not wade through the water without protection.
In that case, you may need to contact local water damage pros. They have the equipment and knowledge to handle contaminated water, remove affected soil or materials, and sanitize the area. This type of cleanup often requires special disposal methods to protect your health and the environment.
Preventing Future Problems
To reduce the chance of this happening again, ensure that any outdoor toilets or portable restrooms are well-maintained and emptied regularly. If you have a septic system, have it inspected by a professional to prevent leaks. If you live in Redmond, keep your septic system records handy.
Also, check for any cracks in your sewer lines or pipes that could leak into your yard. A plumber can help with that. If you notice a recurring issue, a water damage inspection can identify the source. Acting quickly can prevent more extensive damage to your property.

Can I compost human waste?
Composting human waste is not recommended for home gardens. It requires high temperatures and careful management to kill pathogens. Improper composting can leave harmful bacteria in the soil. It is safer to dispose of waste in the trash or through a professional waste disposal service.
What if the waste is from a sewer backup?
A sewer backup is a serious hazard because it can contain raw sewage and other contaminants. Do not attempt to clean it up yourself. Contact a water damage professional who can assess the situation, remove contaminated materials, and sanitize the area to make it safe.
How do I disinfect my tools after cleanup?
Clean your tools with soap and water first to remove any visible matter. Then wipe them with a disinfectant or a bleach solution. Let them air dry. If the tools are porous, like a wooden shovel handle, consider replacing them to avoid cross-contamination.
