What is a pesticide?
Pesticides are substances used to control or eliminate harmful organisms, such as herbicides, insecticides and fungicides.
Which pesticides are involved?
To use a pesticide other than a low-impact pesticide or a biopesticide, a permit is required. The citizen must prove that the infestation is justified and that alternative methods have been exhausted.
Registered contractors
Only registered contractors can apply non-low-impact pesticides. Visit the Emerald Ash Borer page to find a licensed contractor.
