Pesticide Licensing in New Hampshire

Pesticide application

New Hampshie Regulations

New Hampshire law requires that anyone applying pesticides on property that they do not own, as part of their business or not, must be certified (licensed) as a commercial pesticide applicator. Licensing is required regardless of whether the applicator gets paid for the service or whether the pesticide would be classified as general use, including over-the-counter homeowner-type pesticides or "natural" or "organic" materials, or whether the pesticide is classified as restricted use (pesticides that require a certain license to purchase).

New Hampshire commercial applicator licenses are specific to a particular category that is generally defined by the site to which pesticides are applied.
