What Are The Best Pet Friendly Weed Killers?

Are There Weed Killers Which Aren’t Dangerous To Pets?

Many people who own a pet dog or cat have a back garden, or another outdoor space for their beloved pet to frolic in. Obviously, any outdoor space has the potential to turn in to an overgrown forest and if you are not physically able to maintain the space or simply don’t have the time, you will want a herbicide that is both safe for your pet and will keep the weeds at bay.

Some weed killers can kill any seeds that are in the area, in case of a serious weed problem.

What to look for

Is it safe?

When searching for a pet-friendly weed killer, you should ensure that it contains all organic and or natural products. Be aware of harmful ingredients too, such as chloroform, tetrachloride; both are carcinogenic. Steer clear of weed killers containing 2 4-D (or 2, 4- dichlorophenoxyacetic acid) as these are toxic to pets, despite being an organic compound.

Exploring online, there are many options available. Be mindful that almost every weed killer/preventer you will come across in your search will contain glyphosate. Despite many rumours now circling that this chemical is toxic, this claim is largely discredited by many gardeners and chemists. In fact, a small dose of glyphosate is less harmful to you than a cup of coffee!

Is it suitable?

When picking a weed killer, assess the extent of your weed problem. If weeds cover your entire garden, you may want a liquid-based weed killer to cover a wider area. If you have a few weeds in a small corner, a non-liquid based weed killer may be more suitable for your needs.

Safety first

When using any weed killer, make sure you are wearing long sleeves, gloves, and covered shoes. This is to prevent any potential allergic reaction you may have and limits cross contamination with any other plants you may wish to keep.

So, let’s take a look at the best pet-friendly weed killers on the market and the best ones you can make yourself.

DIY Alternatives

If you are on a tight budget, you may wish to try and make your own organic weed killer. Rest assured, many can be made from common household ingredients, are easy to make and are safe for use around your furry friends.


A thick layer of mulch inhibits weed growth in two key ways. Firstly, stopping the weeds from receiving sunlight will prevent them from germinating and spreading and used as a preventative measure, it will prevent many weeds from growing. Secondly, bare soil is the perfect palace for the seeds of weeds to land and germinate. With a thick layer of mulch, they cannot come in to contact with the soil and will die. As it contains no chemicals, it is non-toxic to your pets, children, and wildlife.


Any vinegar that contains a high level of acetic acid makes a perfect homemade weed killer, as the acid kills the leave and thus prevents photosynthesis. Simply apply the vinegar in a spray bottle to your chosen weeds multiple times a week to see the best results. This ensures that the vinegar will deplete the weeds energy reserves and kill them. As vinegar is a liquid, it can be used on wider areas with ease.


Best used in conjunction with other weed killers, cornmeal attacks the seeds of weeds and prevents them for germinating. As it is non-toxic and is a preventative measure, it can be used over a wide area.


A well-known weed killer, salt works by dehydrating the weed or grass. Simply, sprinkle some salt at the base of the plant and repeat every 2-3 days. This is not suitable for use on larger areas as it may kill other plants that you wish to keep alive.

Boiling water

Perhaps the easiest and most overlooked pet-friendly weed killer, boiling water is a great way to kill weeds. Just boil a kettle and pour on to the roots of the weeds a couple of times a day to get the best results. Just make sure any pets or children are not around when you pour it; we want to avoid anyone getting scalded.
