The spotted knapweed on my neighbor's property looks awful! Would you please do an inspection and make them spray it?

When spotted knapweed gets high and dry, it looks bad. Spraying doesn't solve the problem because it's usually too high and too hot to spray. We will gladly do an inspection and inform your neighbor that according to Idaho State Law it is the responsibility of the homeowner to control noxious weeds on their property. This office supports mowing as a control and containment method (which is supported in the State law), but we cannot make people spray their weeds (landowner rights). Also, mowing needs to be done when it's safe, once the weather has cooled and/or rain has relieved the dry conditions.
