Pesticide and herbicide applicator insurance for lawn care

Adding weed control and fertilization is the fastest way to raise revenue per stop on a mowing route. It's also the point where a lawn care business goes from "we might break a window" to "we might kill a lawn, a hedge or the neighbor's tomatoes." Insurers and state regulators both treat spraying as a different business, and your policy should too.

Why your regular liability policy isn't enough

A general liability policy written for mowing usually isn't built for chemical claims. You can see this in how insurers sell the fix: Insureon lists pesticide or herbicide applicator coverage as an endorsement you add to general liability, and notes that lawn care companies offering chemical treatments may pay higher premiums than mowing-only businesses. The Hartford offers herbicide and pesticide application coverage to help pay for costs from the sudden or accidental release of chemicals.

Regulators see the same gap. Virginia requires the certificate a pesticide business files to show any exclusions relating to damage arising from the use of pesticides, and requires the policy to cover liability from handling, storing, applying or disposing of pesticides, plus completed operations.

The second problem is the lawn itself. General liability forms commonly exclude property in your "care, custody or control," and the lawn you're treating is arguably exactly that. Texas deals with it head-on: its structural pest control business licensees must have the care, custody and control exclusion deleted. Ohio requires pesticide businesses to carry a separate professional liability policy or an endorsement covering damage to the properties being treated. Missouri's law goes the other way: its required bond or insurance need not apply to damage to crops, plants or land being worked upon by the applicant. Meeting Missouri's minimum, in other words, doesn't mean the customer's lawn is covered.

Three spray claims to plan for

These are illustrations, not real cases.

A crew member mixes a selective herbicide at the wrong rate and a customer's fescue turns brown in patches across the front yard. The damage is to the property you were hired to treat. Whether you're covered depends on the care, custody or control wording and whether you have an applicator endorsement.

A breezy morning carries a broadleaf herbicide over the fence into the neighbor's vegetable garden. The neighbor isn't your customer, so this is classic third-party property damage, but it arose from a chemical. Without applicator or pollution coverage, the pollution wording in your policy is the first thing the adjuster will read.

A customer says her kids broke out in a rash after playing on the lawn the day it was treated. That's a bodily injury claim tied to a chemical. The Hartford's lawn care page describes its herbicide and pesticide coverage as protection if customers get sick from the chemicals your company uses.

Coverage options and what they cost

• Applicator endorsement on your general liability. The usual fit for a lawn care company doing residential treatments. MoneyGeek puts typical pesticide or herbicide applicator coverage at $45 to $136 a month.
• Contractors pollution liability. A separate policy for runoff, overspray and contamination claims, which MoneyGeek suggests for larger properties and heavier chemical use, at $83 to $500 a month.
• Workers' comp that reflects spraying. Insureon's lawn care page gives a worker who inhales pesticides and gets sick as an example of what workers' comp covers. Make sure your applicators' duties are described accurately to the insurer.

Read the trigger in whatever you buy. If a policy describes its coverage as applying to sudden or accidental releases, ask your agent how a claim that develops slowly, like a lawn that declines over several weeks after repeated treatments, would be handled.

State license insurance minimums

Many states won't issue a commercial pesticide license until they receive proof of insurance, a bond or another form of financial responsibility. We checked each state below on its department of agriculture or environmental agency site. These are legal minimums for the license, not recommendations.

State	License	Minimum insurance or financial responsibility
California	Maintenance Gardener Pest Control Business	$5,000 per person and $10,000 per occurrence bodily injury, $5,000 property damage; or a CD or bond, or a signed self-insurance statement
Florida	Pest control business (includes Lawn and Ornamental)	Bodily injury $250,000 per person and $500,000 per occurrence; property damage $250,000 per occurrence and $500,000 aggregate; or $500,000 combined single limit
Illinois	Commercial applicator (for hire)	Bodily injury $50,000 per person, $100,000 per occurrence, $500,000 aggregate; property damage $50,000; or $100,000 combined with $500,000 aggregate
Maryland	Pesticide business (includes weed and feed)	Bodily injury $100,000 per person and $300,000 per occurrence; property damage $15,000 per occurrence and $30,000 aggregate
Michigan	Pesticide application business	$100,000 bodily injury and $25,000 property damage per occurrence (most categories)
Minnesota	Commercial applicator	$50,000 bodily injury per person and per occurrence; $25,000 property damage; deductible no more than $500
Missouri	Certified commercial applicator	$50,000 per occurrence by bond or insurance; need not cover the land being worked on; deductible up to $1,000
Montana	Commercial applicator	$30,000 liability insurance ($50,000 for aerial); insurance only
New York	Commercial pesticide business registration	General liability of at least $1,000,000 per occurrence
Ohio	Pesticide business	$300,000 per occurrence, $300,000 aggregate and $300,000 products-completed operations aggregate, including coverage for properties being treated
Pennsylvania	Pesticide application business	$100,000 bodily injury and $100,000 property damage per occurrence; must include completed operations; deductible no more than $2,500
Texas	Structural Pest Control Service business	$500,000 bodily injury and property damage, $1,000,000 aggregate; care, custody and control exclusion deleted
Virginia	Pesticide business	$100,000 property damage; $100,000 per person and $300,000 per occurrence bodily injury
Washington	Commercial applicator	$50,000 public liability and $50,000 property damage with a deductible of no more than $5,000; or a $100,000 surety bond

A few notes on reading the table. Texas gives lawn care applicators a choice: an Agricultural Pesticide license in the 3A Landscape Maintenance category or a Structural Pest Control Service license in the Lawn and Ornamental or Weed Control category. The table shows the structural business requirement; the department says commercial agricultural applicators must have insurance if they apply restricted-use, state-limited-use or regulated herbicides. Minnesota also accepts a surety bond or a net assets statement, and says employee applicators are exempt if their employer maintains the coverage. Illinois requires a 30-day cancellation notice on the certificate, and says commercial not-for-hire applicators need no insurance certificate at all.

Fertilizer-only isn't always exempt

Whether you need a license to spread fertilizer depends heavily on the state:

• Texas says applicators who apply only fertilizer don't need a TDA license. Any pesticide, including a general-use product, does.
• Florida requires every commercial fertilizer applicator to be certified by the state to fertilize turf or ornamental areas, including residential lawns. Its Limited Commercial Landscape Maintenance certification lets maintenance crews treat ornamental plants and beds, but not turf, and not with weed and feed.
• Louisiana's Landscape Horticulturist license covers fertilizing, while cutting lawns, edging and hand-weeding need no license.
• Maryland treats weed and feed as a pesticide, so a lawn care company spreading it needs the business license.

The minimum is not the target

California's minimum for a maintenance gardener pest control business is $5,000 per person in bodily injury coverage. Compare that with the $1 million per occurrence that 94% of landscaping businesses buying general liability through Insureon choose. A state minimum is a licensing bar, not a coverage recommendation. Price your coverage from your contracts and your worst realistic claim, then check that it also clears the state's bar.

Before you spray your first lawn for pay

• Check your state's license requirements, including whether your business, not just your applicator, needs a license.
• Tell your insurer, in writing, which products and services you're adding.
• Add an applicator endorsement, and ask whether damage to the treated lawn itself is covered.
• File the certificate your state requires, with the agency as certificate holder if that's what it asks for (Pennsylvania, for one, requires the department to be listed).
• Keep application records. MoneyGeek suggests writing down the products, weather conditions and customer instructions for every fertilizer, herbicide or pesticide job.
