Phos-Chek Wildfire Home Defense Concentrate

Phos-Chek Wildfire Home Defense, previously known as Phos-Chek Long Term Fire Retardant, is the safest, most effective, and environmentally friendly long-term fire retardant available today. This is the same version of the same fire retardant that is used by USDA Forest Service – that is available to homeowners. Phos-Chek Long Term Fire Retardant, is a colorless long-term fire retardant, is easily applied using any garden or agricultural sprayer. Once properly applied, Phos-Chek will help protect your property long before a wildfire begins. This is a concentrate that is made to mix with water and can be used with most simple garden sprayers. Pos-Chek Wildfire Home Defense is effective and safe when used as stated on the label.  It is designed to be applied as a preventative pre-treatment by spraying dry grasses, brush, wood, or other cellulose material around your home at the beginning of fire season.

While Phos-Chek can be applied within hours of a wildfire reaching your home, it is best used as a pre-treatment before a wildfire begins. Therefore, it is best to apply Phos-Chek at the start of fire season, where it will remain effective throughout the entire fire season so long as the weather remains dry. Rainfall of 1/4" or more will wash Phos-Chek off the treated vegetation and it becomes a fertilizer.
