STATE LICENSE
ConditionalMaine Board of Pesticides Control — Depar…
Maine does not license landscaping or lawn care as a trade. The state credential that catches landscapers is pesticide licensing: a 'commercial applicator' includes anyone who uses general-use pesticides in custom application, and custom application means any application under contract or for compensation (22 M.R.S. § 1471-C). No commercial applicator may use or supervise the use of any pesticide without prior certification from the Board of Pesticides Control (§ 1471-D), and the Board names lawn and landscape care and tree and shrub care as examples. Herbicides, including weed-and-feed products, are pesticides.
The Board requires a commercial master applicator for each company and branch, with operators working under them; certification means passing a core exam and a category exam (such as 3A Outdoor Ornamentals or 3B Turf), and masters also pass a regulations exam and an oral exam. The Board's page lists a $70 commercial license (two years, expiring December 31) and a $200 firm license for custom application companies other than sole proprietors without employees. Excavation for hardscape or irrigation requires Dig Safe notice 3 business days ahead.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is a state function of the Board of Pesticides Control. Maine towns may adopt their own pesticide ordinances, so check local rules before treating lawns. Hardscape, grading, and work near water may need local shoreland zoning or site permits, and excavation requires Dig Safe notice statewide (23 M.R.S. § 3360-A).
The local offices section below names the exact permit desk for every Maine county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Applying general-use products such as weed-and-feed for pay is custom application and requires a commercial license (22 M.R.S. § 1471-C).
The Board warns that weed control on sidewalks, patios, driveways, or parking lots needs the industrial/commercial vegetation category, not just turf or ornamentals.
Commercial applicator licenses are company-affiliated and void when the applicator leaves the company.

Pending verification: Minimum liability insurance amounts for commercial applicators and spray contracting firms — 22 M.R.S. § 1471-D(4) leaves them to Board rule (01-026 C.M.R. ch. 31) and the BPC page only references the Affidavit of Insurance Coverage form · BPC fee amounts ($70 commercial license, $200 firm license, $10 per core or category exam, $50 master regulation/oral exams) are from the Board's web page; the fee rule itself was not read · Which Maine municipalities have local pesticide ordinances affecting lawn care (not surveyed) · Whether Maine currently requires a state license for arborists or tree-care companies — not researched for this record · Category numbering conflict on the BPC page: its category list shows 6B Industrial/Commercial/Municipal Vegetation Management, while its warning about sidewalk and patio weed control cites 'Category 6D'
