Louisiana pesticide license for lawn care: $200, plus $50 per sprayer
Checked October 2026
Louisiana licenses the business and the sprayer separately. A lawn care company applying pesticides by ground needs a Ground Owner Operator License from the Department of Agriculture and Forestry: $200 for residents, $500 for non-residents, plus $50 to register each motorized sprayer. It must employ a certified commercial applicator and file a $25,000 surety bond or equal liability insurance. Applicators pass a free General Standards exam plus a $50 Category 3 exam and pay $20 a year for a card.
Louisiana counts your equipment. The Department of Agriculture and Forestry (LDAF) licenses the lawn care company, licenses the person who sprays, and puts a decal on every motorized sprayer in the fleet, with a fee for each one. By our sum, a resident company with one power sprayer, one applicator and one category exam pays $200, $50, $50 and $20 for $320 in the first year, before the bond or the premium.
What it costs to open the business
LDAF's pesticide licensing page lists the requirements for a Ground Owner Operator License, which is the one a lawn company applying by ground needs. The numbers below are as the page and the initial application form read on 2026-10-01.
| Item | Amount |
|---|---|
| Ground owner operator license, Louisiana resident (90 days domiciled) | $200 |
| Same license, non-resident, including a company registered as an out-of-state corporation | $500 |
| Equipment registration, each piece of mechanically powered application equipment, such as a motorized sprayer | $50 |
| Surety bond or equal liability insurance | $25,000 |
| Commercial applicator exam, each category | $50 |
| General Standards exam | Free |
| Commercial applicator card | $20 a year |
The application is mailed with a check or money order. Cash is refused.
The $25,000 and what it won't cover
The statute lets you post a surety bond or, instead, carry liability insurance in the same amount. The rule is stricter than the number. Insurance has to be payable to people proven to have suffered damages from your work, the insurer gives the commissioner 30 days' notice before cancelling, and the policy cannot be applied to damage or injury to the agricultural crops, plants or land you are working on. The same rule bars a licensee from applying any pesticide that the policy excludes.
That makes the filing a floor for third parties, such as the neighbor whose shrubs get drift, and not a policy that pays for a patchy fescue lawn you sprayed. The endorsement that does is in the pesticide applicator insurance guide. You cannot change the amount mid-year without written approval, and the certificate of insurance guide explains who goes on the holder line.
A hand-sprayer exemption that fits a neighbor, not a company
Under the Title 7 pesticide rules, a person applying a general use pesticide to an individual homeowner's lawn is exempt from licensing, provided the product and the equipment belong to the homeowner, the person uses only a hand-held container, and the person neither advertises nor holds out as being in herbicide work. A neighbor kid with the owner's jug qualifies. A company with a branded truck, its own tank and a mailer does not.
The statute behind the license is short: no one may own or operate a business applying pesticides for a fee without the license, per R.S. 3:3243 in the department's December 2020 copy. It also says ground applicators on your payroll must be commercial applicators or work under the direct supervision of one.
The applicator side
The license application must list at least one Louisiana certified commercial applicator on staff. LDAF's page says anyone who applies pesticides must pass the General Standards exam and at least one category exam. For lawns that category is 3, Ornamental and Turf Pest Control, which LSU AgCenter describes as spraying to control pests in ornamental trees, shrubs, flowers and turf. The study set there is the National Pesticide Applicator Certification Core Manual (publication 2959) and the Ornamental and Turf manual (publication 1933).
One wrinkle deserves a phone call. The rule text defines a commercial applicator by restricted use products, while the department's licensing page says anyone who applies pesticides must certify. The statute lets ground applicators on your payroll work under the direct supervision of a commercial applicator, yet section 723 of the same rules says everyone applying under an owner-operator license must keep a current commercial applicator certification. If your sprayer will only ever handle general use herbicide, ask LDAF at 225-925-3763 whether the card is required, and get the answer by email at pestcert@ldaf.state.la.us.
Exam logistics changed recently. LDAF ended testing at district offices on October 15, 2025. Exams are now in person at the main office in Baton Rouge or online through a vendor, Everblue, which charges its own fee that LDAF does not state. The exam application is mailed with payment, and the fee is forfeited if you do not test within 60 days. Applicators licensed in another state can ask for an exam waiver on a reciprocity form with a $20 card fee. Missouri lists Louisiana as a reciprocal state for everything except structural pest control.
Renewal, records and what stays
Business licenses run to December 31 and renew annually. A late renewal carries a $50 fee, and every sprayer is decalled and registered again each year. Applicator certification lasts three years and is renewed by attending an approved meeting or retesting, while the card is $20 every year. Application records are kept for three years and must include the product, rate, date and place.
Fertilizing is a different license
LDAF's nursery and landscape page lists fertilizing under the Landscape Horticulturist license, with a $150 exam and a $125 license fee, and says cutting lawns, edging and hand-weeding beds need no license. A company that fertilizes and also sprays herbicide may need both credentials. The landscaping license page walks through that side, and the pesticide license hub puts Louisiana's fees next to the neighboring states.
