Licensing Info
Moss is a widespread problem on roofs and other structures in the moist areas of the Pacific Northwest. It is not uncommon for people to use products that prevent growth or kill existing moss. In addition, treating wood roofs to prevent wood-destroying pests is also common. Many people do not know that these types of products are classified as pesticides on the state and federal levels and applying them commercially requires a pesticide applicator's license.
Failure to comply with Oregon’s licensing requirements and label restrictions may result in one or more of the following actions: civil penalty, license revocation, license suspension, or refusal to issue or renew the license or certification of an applicant, licensee, or certificate folder in accordance with ORS 634.322(4).
Information and resources on pesticide licensing and searching for registered pesticide products can be found on ODA's website.
