Product Description

Effective in controlling mosses, algae, lichens and liverworts, Moss-Aside™ Moss Killer is safe for lawns, ornamental gardens, around and on homes and home greenhouses. Around the home, we love to use Moss-Aside on roofs, cedar shakes, composition shingles, stucco, redwood, CCA-treated wood decks and fences, brick, stone and concrete walkways, sidewalks, and driveways. It's effective on an endless list of surfaces! Moss-Aside can be used at any time during the year, but for best results, use with actively growing moss in the spring or fall. Do not use on lawns when temperatures exceed 85° F. During warmer weather, apply late in the day. Applications during cold weather may delay appearance of moss damage. Apply with our Handheld Sprayer, or any standard backpack sprayer, tank sprayer, hose-end sprayer, mop, watering can, or brush. Keep the sprayer moving to get an even application.


Dilute concentrate by mixing one part concentrate with 9-19 parts water (6.8-13 oz. per gallon of water). Apply 8-12 gallons of solution per 1000 ft2.

Coverage: Makes 2.4 gallons (at 1:19 parts)
