The annual city-wide herbicide application for noxious weed control begins April 22nd. Application vehicles will be operating between midnight and 6:00am, M-F, through the months of April and May. The primary focus will be to control weeds in the curb/gutter line and gravel shoulders on all of the City’s main roadways.
A yellow dye is mixed with the herbicide to assist with the application. The yellow dye will fade in three to four weeks and application areas are safe for people and pets to enter once the application is dry. If there is inadvertent contact with wet herbicide, it is recommended to remove contaminated clothing and rinse skin immediately with plenty of water for 15-20 minutes.
Please call the City of Kennewick Public Works Department at (509) 585-4419 with any questions.
