Public notice from Boundary County Noxious Weed Control

For 2023 the Boundary County Noxious Weed Department will continue to offer weed identification, site review, herbicide type/rate advice, rental sprayers, booklets, brochures, and other land management information.

Spraying of Road Rights-of-Way: Many county roads will be sprayed with herbicides on weed infested rights-of way this season, mid-April through October.

If you do NOT want the right-of-way adjacent to your property sprayed, obtain a NO SPRAY Agreement from the Weed Department. These forms and accompanying “NO SPRAY” signs are free; the sign MUST BE POSTED by the owner at the property corners.

Property owners are responsible for the eradication of noxious weeds in those areas. We cannot honor signs that are not obtained from our department and, particularly, without a signed agreement. If weed control has not happened on or before July 1st the marked NO Spray area may be sprayed for weed infestations.

Public Notice addition: All property owners who have potable water or irrigation water usage within 50 ft. of a county road right-of-way must mark the area of intake as potable water and notify Boundary County Weed Department prior to May 1 of every year.

Programs: Boundary County will continue to offer our neighborhood CO-OP program. All applications for this program may be obtained from the University of Idaho Extension Office in Bonners Ferry. Applications must be returned by May 1st. This program provides for some reimbursement of herbicide expenses for landowners.
