Why Is Weed Killer Harmful to Pets?

Person spraying weed killer on lawn

Walk through the garden aisle of any home improvement store, and you’ll see dozens of different weed-killing products. Most of them are effective, but most of them aren’t made with the safety of cats and dogs in mind. If you have pets, steer clear of chemical weed killers at all costs.

Many herbicides and pesticides, both of which can be used to kill weeds, are loaded with toxic chemicals.

Most weed killers, such as the popular brand Roundup, contain glyphosate as their active ingredient. Glyphosate is a carcinogen that can cause liver and kidney disease, and exposure to it can even increase your chances for cancer.

Not only is glyphosate harmful to pets, but it’s dangerous to humans as well! It’s not safe for children, adults or animals, so it’s always best to avoid weed killers with glyphosate and opt for a more natural product instead.

Things to Look For in a Weed Killer

If you’re on the hunt for a pet-friendly weed killer, the most important thing is to check the label to make sure it’s made from all-natural ingredients.

It’s also important to know what type of weeds the product can kill. Some formulas are designed to target specific types of weeds, while others can kill dozens or hundreds of different types. Be sure to check the label to make sure that the product you’re buying can destroy the type of weeds in your garden.

One other thing to consider is if the product needs to be mixed or diluted prior to use. Most weed killers are ready to use immediately, but some are concentrated and require mixing and diluting with water. You can save yourself some time by buying one that’s in a spray bottle, ready to use!

Ready to eradicate those unsightly weeds once and for all? Here are fourteen pet-friendly weed killers to try on your lawn and garden:

8. Preen Weed Preventer

If you’d rather be proactive than reactive, you might consider purchasing a pet-safe weed preventer rather than a pet-safe weed killer. 

This option from Preen is 100% natural and is made from just one ingredient: corn gluten meal. While you might think that there’s no way for such a simple solution to be effective, you may just be surprised. Reviewers on Amazon report that the product is great for keeping weeds away without harming the plants you actually want to grow, making it ideal for use in gardens. Some even report using it when specifically growing pet-intended plants (like catnip for cats) and appreciate that it’s a pet-friendly solution that has no chance of harming your beloved fur baby.

The weed preventer must be spread by hand and can be used on new plants up to two to three inches tall, up to the point of harvest. In addition to being used in gardens and flower beds, it can also be used on ground cover and around trees or shrubs, where it remains effective for up to six weeks.

9. ECO Garden Pro

This eco-friendly, biodegradable weed killer is made from salt and vinegar. It’s suitable for killing not just weeds, but also moss, poison ivy and clover if needed.

You can use it just about anywhere — your driveway or sidewalk, flower garden, veggie garden, parking lot, you name it, without worrying about groundwater contamination.

The liquid weed killer comes in a gallon jug and needs to be added to a sprayer (which you’ll have to purchase separately) before application. Once applied, the weed killer starts killing within 24 hours.

10. Wondercide Outdoor Pest Control

Wondercide Outdoor Pest Control

While this product is technically touted as an all-natural insecticide that kills, repels and prevents mosquitoes, ants, fleas and ticks, reviewers report that the spray kills weeds, too. So, if you’re looking for a pet-safe herbicide and insecticide, you might want to consider this option.

It comes in a spray bottle, so all you need to do is attach your water hose and spray away. One bottle treats up to 5,000 square feet of yard space and the formula — which includes cedar oil, sesame oil and other natural ingredients — is safe for use on lawns, patios, vegetable and flower gardens, playgrounds and more.

11. Harris 20% Vinegar Weed Killer

While you can use household vinegar to attempt to kill the weeds in your yard, you may have more luck with this extra-strong option. Harris’s vinegar weed killer is made from 20% extra-strength vinegar (which is about four times the strength of household vinegar) and 80% water —  and that’s literally it. If you’re looking for something extra-simple, you’ve found it.

You can buy this weed killer in an easy-to-use, small, quart-sized spray bottle, or in a large gallon jug that comes equipped with a spray top.

12. BioSafe Systems 7601-1 Weed and Grass Killer

biosafe weed and grass killer

Suitable for organic gardening, this weed and grass killer is known for killing even the most stubborn crabgrass, dandelions and other types of weeds. Do note, though, that it’ll kill everything it touches, so it’s best for use only in areas where you don’t want grass, weeds or anything else growing. 

The fast-acting solution shows results in as little as 24 hours. The primary ingredient is ammonium nonanoate, though, so for this reason, you won’t want your pet to be around the treated areas until they dry; however, ammonium nonanoate is not considered a toxic chemical, just potentially irritating.

13. Bonide Read-to-Use Burnout Weed and Grass Killer

This non-selective weed killer kills everything, but the formula’s clove oil and citric acid are a nice alternative if you don’t want to go with a vinegar-based solution. The Bonide Burnout Weed and Grass Killer formula works within hours after application and in temperatures as low as 40 degrees Fahrenheit. The formula is also waterproof after drying, so you won’t need to worry about it washing away.

14. Dr. Earth Final Stop Organic Gardening Weed & Grass Killer

Dr. Earth’s weed and grass killer, which comes in a handy, small bottle that’s easier to use for those who only want to treat a small area and not their entire yard, is made from a mixture of essential oils. Clove, cinnamon, rosemary and thyme come together to kill everything (or at least every plant) in their path. Once the solution dries, it’s safe for pets and kids alike.

Other Weed Control Solutions for Pet Owners

If none of the above pet-safe weed killer options look right for your needs, you can find other ways to keep your lawn and garden looking pristine without ever setting foot in your local home and garden store.

Skip the Spray and Weed by Hand!

The best pet-friendly weed killer isn’t a weed killer at all – it’s something you already and never have to buy. Instead of arming yourself with a sprayer, we suggest killing your weeds the old fashioned way – by pulling them by hand.

So put on your gardening gloves, get a comfortable mat to kneel on and start yanking those unwanted weeds one handful at a time.

Some people think that weeding by hand is an unnecessary, time-consuming chore. But if you keep up with it regularly, it should only take you a few minutes here and there to get the job done.

Prevent Weeds With Mulch

Instead of trying to kill weeds, you might want to try preventing them instead.

One of the most effective weed preventers that exist is mulch.

Mulch allows you to water your plants and garden less frequently, it can improve your soil’s quality and it puts the perfect finishing touch on flower beds and vegetable gardens. But it’s also a way to stave off weeds.

Weeds will still grow below, but a thick layer of mulch will prevent them from sprouting up. A few may pop up here and there, but they won’t be nearly as noticeable.

The next time you weed your garden beds by hand, spread some mulch around to keep those pesky weeds in the soil where you can’t see them.

Boil the weeds away

One of the simplest DIY methods for killing weeds (or anything else you don’t want growing on your lawn or on your sidewalk or driveway)? Boil some water and then pour it onto the area of concern. 

Jeremy Yamaguchi, CEO of Lawn Love says this method is one of his favorites. “Using boiling water to kill weeds is one of the easiest tried-and-true methods. You don’t have to go out and buy special weed-killing spray, and you don’t have to worry about using harsh chemicals that might potentially harm your roaming pets or wildlife. However, since boiling water can successfully kill weeds down to the root, you want to make sure that you are only using this method on weeds that are not intermixed or even near
other plants (that you want to keep alive). The boiling water will impact all of the plants and roots that it touches.”

So, keep in mind that this solution is best suited for killing those stray weeds that pop up around your patio but may not be the best solution in the middle of your yard.

Spray a little vinegar

You’ll see that many of our pet-friendly products listed above use vinegar as a primary ingredient, and for good reason. Vinegar will kill weeds easily (as well as other, non-weedy plants). The good news is, you likely already have vinegar in your pantry, so you can simply add your vinegar to a spray bottle and start spritzing.

Spray on the salt

Salt is also a useful weed killer. Dissolve salt in water at a ratio of about 1 part salt for 3 parts water, and add the mixture to your spray bottle for an easy solution that’s also incredibly cheap.

Try some landscape fabric

If you’re particularly worried about weeds popping up around your garden or landscaping, you might want to consider adding some landscape fabric to that garden. The landscape fabric will blend into your plants and keep weeds from popping up. 

Landscape fabric is easy to apply and often very affordable at any lawn care or big-box store. When you’re ready to re-do your landscaping and remove the fabric, all you have to do is pull it up.

Pet-Safe Weed Killers FAQs

Have more questions? We’ve got answers.

What harmful ingredients should I watch out for in a weed killer?

If you’re not shopping specifically for a weed killer that’s branded as safe for use around pets, there are a few harmful ingredients you can watch out for in other products, that you may want to avoid if you do have pets frequently around the area where you intend to apply that product.

Glyphosate is one of the most harmful weed killer ingredients and the main ingredient in most popular weed killers. Unfortunately, glyphosate is a carcinogen.

Trimec is another popular weed-killer ingredient. It is considered safe for both pets and children if used as directed, but you will have to keep pets and children away from the wet liquid for a few hours after application. When wet, the ingredient is still considered harmful. If this is a worry for you, you’ll want to avoid trimec in your chosen weed killer.

Lastly, sethoxydim is considered “slightly toxic” if ingested and irritating if touched. It can cause skin and eye irritation and inhalation can cause throat and nose irritation.

For the safest options for your pets and overall family, avoid weed killers and other products that contain any of the above.

How long should I keep my pets away from weed killers?

Look for information on your chosen product’s safety label. That should tell you approximately how long you should keep your pet away from the area where you used the product. Err on the longer side of things, just to be safe. Additionally, keep your pet out of the area (preferably indoors) when you’re actually applying the weed killer.

Can my pet be harmed by my neighbor’s weed killer?

Unfortunately, yes. While you may choose not to use any chemical-laden weed killers in your yard — or even any weed killers at all — if your neighbors choose to do so, your pet can still be at risk.

If you’re worried about this, talk to your neighbor and ask them if there’s any way they might consider a pet-friendly herbicide. If they’re not open to that or you don’t feel comfortable making this ask, you can instead ask them to notify you when they’ll be applying their herbicides, so you can keep your pets indoors at this time (preventing any exposure caused by wind, etc.). You can also make sure to keep your pet away from their property during walks or playdates.

What are the symptoms of weed killer poisoning?

If you suspect your pup may have gotten into some weed killer, no matter the amount, you may want to watch for a few symptoms that indicate a need for urgent medical care. 

Look for excessive drooling, skin irritation, gastrointestinal upset, loss of appetite, tiredness or, in extreme cases, seizure-like movements. If you notice any of these, call the ASPCA animal poison control center at 888 426 4435 or call your local vet immediately.

Are pet-safe weed killers really safe for my dog?

It’s worth noting that, even if a product says it’s “pet safe” that doesn’t necessarily mean that it absolutely cannot harm your dog in any way. Anything can be harmful in the right quantities. 

So, even if you’re using a pet-safe weed killer, keep it away from your dog, where they can’t easily access it, and don’t allow them to roll around in the grass until the killer has thoroughly dried. As always, make sure to read a product’s full safety instructions and cautions, to ensure proper usage.

Are pet-friendly weed killers as effective?

Unfortunately, no. You can’t really beat the effectiveness of a chemical-heavy weed killer. However, those weed killers come with lots of risks, not only to your pets, but your family as well. 

As you decide whether you want to go with a pet-friendly or a potentially toxic weed killer, you’ll have to weigh the pros and cons. While pet-friendly weed killers are safer, they also aren’t great at killing weeds long-term, can stain concrete or other surfaces, and may kill other plants around your weeds, such as grass, flowers or vegetables, depending on the solution used.

How Can You Kill Weeds Without Harming Your Pets?

There are plenty of ways to get rid of weeds and unwanted plants without having to use harsh chemicals that can harm your pets.

From vinegar-based solutions to the old-fashioned method of pulling weeds by hand, there’s no reason to jeopardize the health of your pets, yourself or your children by using weed killers loaded with chemicals.

There are plenty of natural, organic and biodegradable products on the market. With the right stuff, you can keep your loved ones safe and make your lawn and garden look better than ever!
