Buying Guide

Unless you are a lawn care expert, you may not know what to look for in a weed pesticide that will not harm your pets. We have compiled a guide to help you find a product that eradicates weeds without harming your furry companions.

1. Which Ingredients Should I Avoid?

Conventional herbicides contain many potentially harmful ingredients, but the “big three” to watch out for are glyphosate, Trimec, and sethoxydim.

According to a 2012 study, RoundUp’s primary ingredient, glyphosate, increases the likelihood of canine cancer by 70%. Although it is popular because it apparently destroys anything it touches, including your pets, it is hazardous.

Trimec is a plant hormone that causes weeds to grow abnormally, eventually leading to their demise. Many pet owners are understandably hesitant to use a product that interferes with hormone production around their pets, despite the claims of the manufacturer.

Sethoxydim is considered “slightly toxic.” It supposedly only irritates your pet’s eyes, skin, and throat if they come into contact with it. Even if that is the extent of the harm, you probably do not want your pets frolicking around in it.

2. How do Pet-Friendly Weed Killers Work?

Most use vinegar instead of toxic chemicals as their primary ingredient. Vinegar robs plants of their moisture, causing them to wither and die.

Many natural weed killers also contain dish detergent, a surfactant that allows the spray to remain on the foliage rather than being absorbed by the plant, allowing the formula to work quickly.

Some products prevent plants from growing in the first place, and maize gluten is commonly used in these products. Corn gluten prevents seeds from developing roots after germination, preventing them from becoming weeds.

3. Are There Any Negative Aspects of Pet-Friendly Weed Killers?

Yes. The truth is that they are not as effective as harsh herbicides like RoundUp, but many pet owners are willing to make that sacrifice if it means keeping their pets safe.

Many vinegar-based solutions can increase the soil’s sodium content over time, causing brown patches in the grass. They are also ineffective at destroying root systems, so plants often return quickly.

Most natural herbicides are also nonselective, meaning they will destroy any plant they come into contact with, including your plants and vegetables. Therefore, caution must be taken when using them.

In addition, many solutions will stain surfaces such as metal or concrete.


1. What are weed pesticides that are safe for pets?

Pet-safe weed killers are natural, non-toxic solutions that can eliminate vegetation without harming animals or the environment.

2. How do pet-friendly weed pesticides work?

Most pet-safe weed killers contain natural ingredients, such as vinegar or maize gluten, to destroy weeds. Vinegar absorbs moisture from weeds, causing them to wither and die. Corn gluten prevents weeds from sprouting by stopping seed roots from developing.

3. Are pet-safe herbicides as effective as conventional herbicides?

Natural weed killers may not be as potent as conventional herbicides, but they are safer and more environmentally friendly. Multiple applications may be required to eradicate vegetation completely.

4. Are pet-friendly weed pesticides safe for children and pets?

Yes, pet-safe weed killers are safe for use around pets and children when used as directed. However, it is recommended to keep pets and children away from the treated area until it is completely dry.

5. Are pet-safe herbicides more expensive than conventional herbicides?

Pet-friendly weed killers can be more expensive than conventional herbicides, but they provide a safer and more environmentally friendly alternative. Consider your budget and select a product that provides excellent value.

6. Can herbicides safe for pets be used on all types of weeds?

Pet-safe weed killers are effective against most broadleaf weeds and vegetation. However, multiple applications may be necessary to eradicate weeds completely, and some weeds may require more potent treatments.

7. How long after weed killer application is it safe for pets?

As a general rule, you should keep your dog indoors for at least 48 hours following a chemical lawn treatment.
