How to kill moss with vinegar

Updated April 17, 2017

Vinegar can be used as an herbicide and pesticide. It is an inexpensive, and environmentally safe, alternative to chemical products. According to the United States Department of Agriculture, vinegar in five to 10 per cent concentrations is effective in killing weeds within the first two weeks of their life cycle. Average household vinegar is available in a five per cent concentration. Vinegar in higher concentrations is effective at killing older plants. Moss is a rootless, non-flowering plant that grows predominantly in moist environments. It can be invasive and many homeowners seek natural methods to kill moss. Both apple cider vinegar and white vinegar can be used to kill and prevent future growth of moss.

  1. Pour full strength vinegar directly onto moss. For newer moss growth household vinegar can be used. Older growth requires an industrial strength vinegar.

  2. Allow the vinegar to sit for five to 10 minutes.

  3. Scrape off the moss. If the surface allows, use a putty knife to remove the moss.

  4. Scrub the surface. Rinse off the vinegar and any remaining moss. Reapply if necessary.

  5. Mix together 4 cups of vinegar, a 1/4 cup of salt and 2 tsp dish soap.

  6. Pour mixture into a plant sprayer or spray bottle.

  7. Saturate the moss with the mixture. Let the mixture sit and then remove the moss.

  8. Tip

    To prevent moss growth, spray an area with vinegar.


    Vinegar will kill any plant life. Do not allow the vinegar, or vinegar mixture, to touch any plant growth you wish to keep. Vinegar is an acid and can damage some surfaces. Test any surface prior to applying.
