As a trusted lawn care company based in Ottawa, Ontario, Thomas Lawn Care understands how important it is for our customers to know that the products we use are safe for both people and pets. We prioritize the health and well-being of our clients and their beloved furry companions, which is why we're committed to using products that are not only effective but also safe for the environment.


Onesuch product we use is Fiesta, a broadleaf weed control solution that's not only effective in reducing unwanted broad leaf weeds, but also safer than most alternatives (not to mention, the only legal selective herbicide in Ontario). Fiesta's active ingredient has a relatively high LD50 of 5,000 mg/kg, which makes it less lethal than table salt (with an LD50 of 3,000 mg/kg). This means that Fiesta is safe to use around people and pets.


To ensure the utmost safety after applying Fiesta broadleaf weed control, we recommend that you keep off the lawn for a minimum of three hours or until the product has completely dried. This allows the solution to be absorbed by the weeds without the risk of it being accidentally ingested or coming into contact with people or pets. After this time frame, it's safe to reenter and enjoy your beautiful lawn.


Though Fiesta is considerably safe, it's still essential to prevent any ingestion of the product. Some animals are known to nibble on grass from time to time, so we advise keeping an eye on your pets and preventing them from consuming any treated grass for at least 24 hours after an application.


In addition to Fiesta, we also use other eco-friendly and pet-safe products in our lawn care routine. Our fertilizers are designed to nourish your lawn without posing any risk to people or pets who come into contact with them.


Moreover, we incorporate the use of biological insecticides like Biotitan and GrubTerminator in our lawn care treatments. These products are specifically designed to target and control insects and grubs, without posing any harm to mammals such as your pets. The safety of these biological insecticides comes from their targeted mode of action, which ensures they affect only the intended pests and not other organisms.


Biotitan and GrubTerminator work by introducing naturally occurring bacteria (GrubTerminator: Bacillus thuringiensis galleriae)  and fungi (Biotitan: Beauveria bassiana strain ANT-03 ) to the soil, which are lethal to pests like grubs but harmless to humans, pets, and other wildlife. These products are not only pet-safe but also environmentally friendly, making them an excellent choice for maintaining a healthy and thriving lawn.


By using products like Fiesta, Biotitan, and GrubTerminator, we can ensure that your lawn is well-maintained, free of weeds and pests, and safe for your family and pets to enjoy. Our commitment to safety and eco-friendliness is a testament to our dedication to providing top-quality lawn care services that you can trust.
