How to Kill Moss with Vinegar

By Joshua Duvauchelle ; Updated September 21, 2017

Moss often crops up in wet and humid areas, and can be prevalent on shaded walkways and patios. Though you could use a commercially prepared chemical mossicide, highly acidic vinegar can also kill mos--and is more natural and gentler than chemicals. Use vinegar to kill moss on any hard outdoor surface and restore the moss-free beauty of your landscape.

Pour straight white or apple cider vinegar into a plastic spray bottle. Do not dilute the vinegar with water.

Spray the moss growth with the vinegar. Soak the moss until it is thoroughly moistened. Let the vinegar sit on the moss for 10 minutes, during which the vinegar works against the moss in order to kill it.

Rinse down the area with a strong jet of water from a garden hose. Brush away the moss with the hose or by using a broom or sponge.

Spray the vinegar on the area again if any green marks or stains are left behind after the moss growth has been removed. This further sterilizes the area of any resident moss spores and helps lift any stains. Let sit for 10 more minutes, then rinse with hose.


Things You Will Need

  • White vinegar or apple cider vinegar
  • Plastic spray bottle
  • Garden hose
  • Broom or sponge


  • Don't use vinegar in your garden or lawn as the acidic liquid can kill other types of vegetation besides the moss.
