TruGreen’s standard lawn treatments use synthetic herbicides and fertilizers that carry real health and environmental risks, particularly for children, pets, and anyone spending time on treated grass. The company markets its services as safe and environmentally responsible, but a 2020 lawsuit alleged those claims were false and deceptive. Whether the risk level is acceptable depends on your household, your exposure patterns, and how strictly you follow re-entry guidelines after each application.
What Chemicals TruGreen Applies
TruGreen’s weed-and-feed products contain a blend of herbicides sold under the Trimec brand name. EPA product labels for TruGreen formulations list three active ingredients: MCPA (a chlorophenoxy herbicide), mecoprop-p, and dicamba. These are broadleaf weed killers designed to target dandelions, clover, and similar plants without harming grass. The active chemicals make up roughly 1% of the product by weight, with the remaining 99% classified as inert ingredients, a category that can include surfactants and solvents that help the herbicides absorb into plant tissue.
TruGreen’s programs also include synthetic nitrogen and phosphorus fertilizers, applied multiple times per year. The specific chemicals vary by region and service plan, but the core approach relies on conventional, EPA-registered pesticides rather than organic alternatives.
Health Concerns With Common Lawn Chemicals
The herbicides in TruGreen’s products belong to chemical families that have been linked to a range of health problems in epidemiological research. Glyphosate, widely used in residential lawn care, is associated with a 30 to 41% increased risk of non-Hodgkin lymphoma. Prenatal pesticide exposure has been linked to a nearly threefold increase in childhood leukemia risk. These are population-level associations from large studies, not guarantees of harm from any single lawn treatment, but the pattern across research is consistent enough to raise concern.
Beyond cancer, many common lawn pesticides act as endocrine disruptors. They interfere with the body’s hormone signaling, and chronic exposure has been associated with diabetes, reduced sperm count, and reproductive disorders. The Massachusetts Medical Society notes that even at levels below the threshold for acute toxicity, pesticide exposure is linked to neurodevelopmental effects in children, including lower IQ scores, learning disabilities, and a roughly 60% increased odds of autism.
Cardiovascular effects have also been documented, including heart rhythm abnormalities, high blood pressure, and increased risk of cardiovascular death in the general adult population. These risks are dose-dependent and cumulative, meaning frequent, long-term exposure matters more than a single application.
Risks for Children and Pets
Children and dogs face higher exposure than adults for a simple reason: they’re closer to the ground. Kids play in grass, put their hands in their mouths, and absorb chemicals through their skin more readily than adults do. Dogs walk barefoot on treated lawns and groom themselves by licking their paws and fur. Both are more vulnerable to the effects of pesticide residue pound for pound because of their smaller body weight.
After a TruGreen application, the standard recommendation is to keep children and pets off the lawn for 24 to 72 hours, depending on the product used. The grass should also be thoroughly watered before anyone walks on it again, as watering helps move the chemicals into the soil and off the grass blades. In practice, many homeowners let their families back on the lawn as soon as it looks dry, which may be well before the recommended waiting period has passed. If you use TruGreen, ask your technician for the specific re-entry interval for each product applied and follow it closely.
The Lawsuit Over TruGreen’s Safety Claims
In 2020, the nonprofit Beyond Pesticides sued TruGreen in D.C. Superior Court, alleging the company’s marketing was false and deceptive. TruGreen had told consumers it would “not approve products containing known or probable human carcinogens” as defined by the EPA, the National Toxicology Program, or the International Agency for Research on Cancer. It also claimed its products were not known skin sensitizers and would not leach into groundwater.
The lawsuit argued these statements were flatly untrue. Several chemicals in TruGreen’s standard product lineup have been classified as possible or probable carcinogens by one or more of those agencies, and some are known to move through soil into groundwater. The complaint was filed under the D.C. Consumer Protection Procedures Act, which prohibits misleading representations in consumer marketing. The case highlighted a gap between what TruGreen told customers about safety and what the scientific record actually shows about its products.
Environmental Impact
TruGreen’s fertilizer applications add synthetic nitrogen and phosphorus to your lawn, and whatever your grass doesn’t absorb washes into storm drains, streams, and eventually larger waterways during rain. This nutrient runoff is one of the biggest contributors to water pollution in the United States. When excess nitrogen and phosphorus reach lakes, rivers, or coastal waters, they fuel explosive algae growth. These algal blooms deplete oxygen in the water, creating dead zones where fish and other aquatic life suffocate. Some blooms also produce toxins that are harmful to humans and pets who come in contact with contaminated water.
Herbicide drift is another concern. When products are sprayed in windy conditions, fine droplets can travel well beyond your property line. University of Florida research notes that some pesticide labels require a 250-foot buffer between the application site and sensitive areas like homes, water bodies, or wildlife habitat. If your TruGreen technician applies product on a windy day, herbicide particles can reach neighboring gardens, open windows, and nearby waterways. Closing windows and turning off air conditioning during nearby applications is a practical precaution.
What About TruGreen’s “Natural” Options?
TruGreen has marketed programs described as more natural or environmentally friendly, but the company’s EPA-registered product labels still list synthetic herbicides like MCPA and dicamba as active ingredients. Without transparent, independently verified ingredient lists for each service tier, it’s difficult to confirm whether any TruGreen program is truly organic or chemical-free. If a pesticide-free lawn is important to you, look for companies certified by the Organic Materials Review Institute (OMRI) or similar third-party organizations, or manage your lawn with compost, overseeding, and manual weed removal.
How to Reduce Risk If You Use TruGreen
If you choose to keep your TruGreen service, a few steps can meaningfully lower your household’s exposure. Wait the full 24 to 72 hours before allowing children or pets on the lawn after any application. Water the lawn thoroughly before anyone returns to it. Remove shoes at the door to avoid tracking residue inside, where it can persist in carpet and on floors for weeks. Ask your technician for the product name and EPA registration number for every application so you can look up the safety data yourself.
Pay attention to application timing relative to weather. Rain within 24 hours of a treatment can wash chemicals directly into storm drains before they bind to soil, increasing both environmental runoff and uneven lawn coverage. Wind speeds above 10 to 15 miles per hour increase drift onto neighboring properties. You have the right to request that your technician reschedule if conditions aren’t favorable.
For households with infants, pregnant women, or immunocompromised family members, the risk calculus shifts. The epidemiological evidence on prenatal exposure and early childhood neurodevelopment is strong enough that reducing or eliminating synthetic pesticide use on your own property is a reasonable precaution.
