For household use only. Not for use indoors.

Kill unwanted patches of moss quickly and easily with Moss Out. Moss competes with the turf and creates thin areas in the grass. Moss growing under ornamental shrubs and in flower beds is unsightly and can harbor insects. The best time to control moss is when it is actively growing. Moss grows most vigorously during rainy periods in spring and fall, but will grow all year in some shady or moist areas.


  • KEEP Moss Out Off Surfaces Such As Sidewalks, Patios, Wooden Decks, Driveways and Clothing.
  • Sweep concrete surfaces immediately to prevent staining.
  • If concrete is wet when contact occurs, staining may be impossible to prevent.



Apply anytime the lawn is moist and moss is actively growing. Treatment in fall or early spring is most effective. Mow the lawn to expose moss and remove clippings.


For spot treatment, sprinkle granules over mossy areas in lawn. Use diagram as a guide for application rate. This container will treat up to 1,250 square feet of lawn. Immediately after sprinkling granules, water treated areas thoroughly. A gentle rain, even immediately after spot treatment, will not significantly affect the moss-killing ability of this product. Wait several days until moss turns black and dies, then gently rake it out. Since grass may be slow to fill in bare spots, we suggest reseeding. To reduce soil acidity which may contribute to moss growth, apply Lilly Miller Super Sweet or Lilly Miller Soil Sweet lime according to label directions. Apply lime anytime—before, during, or after moss control treatment.


Apply anytime moss is actively growing and the soil is moist. Sprinkle granules over mossy areas. See diagram for application rate. Immediately after sprinkling granules, water treated areas thoroughly. Wait several days and carefully rake out dead moss. IMPORTANT: This product will burn foliage if applied directly to flowers or ornamental shrubs. If contact occurs, use a hose to wash this product off these plants right away.

    Moss out

    By Ann on 08/14/2015

    This is the best product for moss in the lawn that I have ever used. I used to be able to get it locally and then it wasn't avaiable so I ordered online. It turns the moss black in about one to two days. You can rake it up or leave as I did and my zoysia spread through the dead moss.
