Traditional weed killers are effective, but most also contain a handful of toxic ingredients that can be harmful to your family, your pets, and the environment. Common toxic weed killer ingredients include:
Glyphosate: A commonly used herbicide in weed killer brands like Roundup, glyphosate is categorized as a “possible human carcinogen” by the World Health Organization’s IARC. A recent study on rats also found glyphosate to cause multiple types of cancer.
2,4-D (2,4-Dichlorophenoxyacetic Acid): Another widely used herbicide, 2,4-dichlorophenoxyacetic acid is a neurotoxicant that can cause skin and eye irritation on contact, coughing and dizziness if inhaled, and vomiting, diarrhea, headaches, and confusion if ingested. It easily drifts and is known to be toxic to wildlife and pets.
Diquat Dibromide: Typically used in “glyphosate-free” weed killers, diquat dibromide is a fast-acting herbicide, neurotoxin, and carcinogen linked to Parkinson’s disease. A 2025 study also links this toxic ingredient to organ and gut bacteria damage.
Dicamba: A highly volatile benzoic acid herbicide, dicamba can drift for miles and stays in the air for days. While its toxicity is considered low if ingested, it is classified as a suspected endocrine disruptor and can cause skin irritation on contact.
So when you spray products with these toxins on weeds, they don’t just land on the leaves and stems—they sit on your driveway, your walkways, and the areas around your home where people and pets spend time. And considering you’ll likely need to use weed killer more than once throughout the season, that exposure adds up. Kids and pets are especially vulnerable. Your little ones and Fido are the members of your family who play in the yard and driveway most, and their smaller, developing bodies are less equipped to process toxic herbicides.
If you’re looking for a non-toxic weed killer that actually works, skip the harsh chemicals. This eco-friendly weed killer uses simple household ingredients to clear driveways and sidewalks safely. The best part? You likely already have many of these ingredients in your pantry.
Step 1: Add vinegar to a bucket and salt to the bucket and stir to combine.
Step 2: Mix in Truly Free Home Dish Soap
Step 3: Unscrew the top of the spray bottle and place the funnel in the top of the bottle. Step 4: Carefully pour the non-toxic weed spray into the spray bottle or garden pump until full.
Now that you’ve made your non-toxic weed killer recipe, it’s time to get to work. Spray the mixture directly onto weeds, especially in areas like driveways, sidewalks, and between pavers.
For best results:
You should start to see the weeds dry out and break down within a few days.
Weeds are persistent, so there’s no one-time fix that keeps them gone forever. But having a go-to non-toxic weed killer recipe makes it easier to stay on top of them without introducing toxins to the places your family hangs out and plays. All it takes is a couple of minutes, a few simple ingredients, and you have one less thing to worry about around your home.
