Buying Guide

Match product form to the job

Choose concentrates for large lawns, hose-end sprayers for siding and walkways, and zinc strips for ongoing roof prevention to suit surface and scale

Check active ingredients

Ferric sulfate and proprietary algaecides target moss on lawns and concrete, while zinc prevents regrowth on roofs—select based on the surface you're treating

Consider application effort

Hose-end and ready-to-spray formulas reduce labor for large areas, whereas concentrates require mixing but can be more cost-effective per treatment

Think about long-term vs immediate control

Zinc roof strips offer passive, long-term prevention, whereas cleaners and liquid treatments remove existing moss and stains quickly

Review safety and surface compatibility

Confirm label guidance for plants, pets, and materials like vinyl or asphalt shingles to avoid damage or unintended exposure
