How to Kill Moss With Household Ingredients

Typically found growing on tree bark, the forest floor and other damp areas, moss is a common non-flowering plant that can quickly cover large areas such as sidewalks and walls. The moss traps moisture between itself and the surface on which it grows. This trapped moisture will cause fungus, such as mold, to begin to grow. Moss can become quite slippery, which creates a safety hazard when growing on walkways. Kill moss with a few household ingredients.

Moss may look magical, but it can cause a variety of problems.
  1. Push the moss off the surface using the pressure from a water hose. Brush any remaining moss from the surface using a stiff-bristled brush broom.

  2. Fill a bucket with 1 gallon of warm water. Add 1/2 cup of household bleach. Mix the contents together with a spoon.

  3. Saturate the stiff-bristled brush broom with the mixture. Scrub the surface with the saturated brush broom. Dip the broom back into the mixture when the broom becomes dry or soiled.

  4. Continue scrubbing the surface until you have thoroughly cleaned the area. Allow the mixture to sit on the surface for 10 to 15 minutes.

  5. Rinse the mixture off the surface with the water hose. Allow the surface to air dry. Repeat the process if necessary.


  • Bleach can kill plant life and harm humans, pets and wildlife.
