WA Pesticide Application Signs
RCW 17.21.410 of the Washington Pesticide Application Act establishes the posting requirements as they relate to landscape applications. The purpose of this requirement is to protect any individual who may be entering the treated area.
The law requires a certified applicator making a landscape application to place a marker at the usual points of entry to the property. Markers must be placed at the time of the application, be a minimum of four inches by five inches and contain the words: “THIS LANDSCAPE HAS BEEN TREATED BY” as the headline and “FOR MORE INFORMATION PLEASE CALL” as the footer. The company name and service mark with the applicator’s telephone number where information can be obtained shall be included between the headline and the footer on the marker. The letters and service marks shall be printed in colors contrasting to the background.
