Best Pet Friendly Weed Killer for 2022

For the green-fingered among us, there’s no better weapon than an all-powerful weed killer. It can help your garden stay clear of those unsightly growths without killing your good plants.

However, the well-being of your pet should always take priority over the beauty of your garden. This means picking a pet-safe weed killer.

It is not recommended that you choose an everyday garden centre solution. Standard weed killers often contain chemicals that can severely poison any animal. Weed killers can also have a negative effect on wild animals, too.

But finding a pet-safe solution is almost impossible and takes even more digging than you’re used to. Even some which are labelled as ‘pet friendly’ still contain ingredients that could potentially be hazardous.

Glyphosate is not only harmful to dogs but the WHO also says it is “probably carcinogenic” to humans, too. You should also avoid Disulfoton, Sodium Arsenite, Metaldehyde, Ammonium Sulfamate, and Borax.

So to save you some time and help you find a weed killer which won’t harm your fluffy little loved ones, we’ve searched high and low for the most effective products on the market, that won’t be toxic to pets and wildlife.

Because all creatures great and small should get to enjoy your beautiful garden!

    The Top Pet Friendly Weed Killers Reviewed

    WeedKil Garden Weed Killer

    If you’re looking for an option as close as you can get to a standard weed killer, our recommendation is WeedKil’s Glyphosate-Free Solution, which is one of the only products on the market to advertise itself as child and pet friendly!

    An organic product using only natural ingredients, it’s a ready to use, fast action spray solution to be used on gardens, patios, paths and gravel, and gives the best results on smaller weeds of 10cm or less.

    Taking its inspiration from homemade weed killing solutions, WeedKil utilises 60g of acetic acid in its ingredients, one of the main components found in vinegar, making it a safe and easy way to handle annual and perennial weeds.

    Like with standard weed killers though, it’s recommended that you keep pets out of the garden when applying and to only let them back in once the product has dried.

    This is mainly to ensure they don’t get the product on their feet and transfer it to your lawn, accidentally killing the grass!

    And with a drying time of just 15-20 minutes, you’ll all be back in the back garden in no time at all!

    Best of all, Weedkil is also not affected by temperature changes and so can be used all year round, with one bottle providing up to 35sq metres of coverage!


    • Works within 24 hours
    • Natural ingredients
    • Effective all year round

    Roundup 119871 Naturals Glyphosate-Free Powerful Weed Killer

    For those who are all about a glyphosate free concoction, this ready-to-use spray from weed killing pros Roundup is sure to appeal.

    It is available in a range of sizes depending on your task at hand, and because it is 100% natural it is safe for pets and wildlife. Still, give it some time to work and dry of course, but it is at least peace of mind if you have cats that you can’t stop going into the garden. It naturally breaks down in the soil, so will leave no residue.

    The Roundup natural weedkiller dries quite fast, especially on a warm day. Use before flowering and planting at the start of the spring season and it will work before wildlife starts to visit.


    • Natural ingredients
    • 24 hour results
    • Powerful results as per reviews


    • Size: 1L, 3L, 5L

    Parkland® 2000W Electric Weed Killer Burner Wand

    Forget sprays and liquid solutions, the best way to combat weeds in a completely chemical-free way is to do it yourself – physically!

    However, pulling weeds out of the ground is tough, back-breaking work and so we recommend investing in this Parkland 2000w Electric Thermal Weeding Stick, a flame-free burning tool designed to kill weeds through intense heat!

    Delivering a thermal shock of up to 600 degrees Celsius right to the heart of the weed, this burner destroys a plant’s internal cells, causing them to wither and die in just 24-48 hours.

    Although that sounds like a serious amount of firepower, don’t let it put you off, as a protective, metal cone around the heating stick implement allows you to give targeted treatment without damaging any nearby flowers or shrubs and also prevents you from accidentally coming into contact with the seriously hot end!

    For those who struggle with stooping it boasts an extra long handle to prevent you from having to bend over and it’s also detachable to help you store this bazooka sized product away with ease.

    With no gas canister, it’s electrically operated through a standard UK plug, however we would suggest using an extension lead as the burner’s own cable is relatively small.

    Highly efficient and environmentally friendly it’s undoubtedly the finest way to kill weeds!


    • Burner with no gas or flame risk
    • Built-in retractable stand
    • Directive cone for accurate treatment


    • Weight: 1.5 Kg
    • Dimensions: 101 x 8 x 10 cm

    You need something which can easily cover a large area but is safe for pets and kids alike.

    Weeds are dead within 24 hours, and you can then start to replant or sow seeds. It is even rain-fast in just 3 hours. Because it is so quick to work, you can even avoid letting your pets outside for a few hours if you want to be extra cautious, but there really is no need.

    Buy it in a 1, 3 or 5 litre bottle and make use of the sprayer which helps with quick application.

    Buying Guide

    How we chose the best pet-safe weedkillers

    When choosing a weed killer that is safe for pets and wild animals, you need to avoid certain ingredients:

    • Glyphosate
    • Disulfoton
    • Sodium Arsenite
    • Metaldehyde
    • Ammonium Sulfamate
    • Borax
    • Trimec
    • Sethoxydim

    We first looked for weed killers that described themselves as pet-safe, and then double-checked the ingredients lists.

    The reason you might be finding pet-safe weed killers difficult to come by and why many weed killers leave their descriptions so vague is because creating a weed killer that is completely non-toxic to pets is incredibly difficult.

    To be effective, standard weed-killers need to contain all kinds of powerful chemicals and creating a solution without them just wouldn’t be as effective. Some of the most popular weed killers in the world such as regular Roundup and Weedol often use glyphosate as one of their main ingredients, and it’s a chemical widely used in the growing of our own crops.

    While glyphosate is still technically labelled as being pet-safe, and the amount used in a shop-bought weed killer is likely to be too low to have a real effect, the WHO says it is carcinogenic to humans, so we wouldn’t recommend risking it.

    This is also the case for Trimec and Sethoxydim-based products too, with Trimec having a worse effect on dogs and Sethoxydim being known to cause anemia in pets.

    Other Buyers Ask...

    How do I use weed killer safely around pets?

    The products we’ve included in our list are some of the safest options we could find, however as a sacrifice, they may not kill weeds as effectively as nasty chemical products.

    If you do decide to go back to a stronger, more effective solution, we recommend always following these guidelines to keep your animals as safe as possible!

    Read the label

    This one is a super obvious suggestion, but we’ve all been guilty of glancing at the back of a bottle or skimming through instructions before going ahead and winging it.

    However, this isn’t smart if applying weed killer, as for them to be effective you have to correctly administer the right amount.

    Over-using a product will simply put your pets at risk, while also not providing better results.

    Keep pets inside

    Even if you are using a pet-safe weedkiller, we would recommend keeping your pet indoors for a few hours until it dries.

    Don’t think this allows you to use a non-toxic weed killer though – even when dried, it can still linger. Plus, you can’t always guarantee your cat won’t find every which way to escape the house.

    After applying a weed killer, it’s best to wait 24 hours before letting your pets back into the garden. This will not only ensure the product has dried, but that it has also effectively soaked into the soil.

    If your pet usually goes to the toilet outside, take them for a walk or utilise a litter tray to keep them away from treated areas.

    Can I kill weeds without using weed killer?

    Still not convinced they’re safe to use? While they won’t be as strong as chemical weed killers, you can use natural homemade methods to keep weeds at bay.

    We have found the best home remedies to be:

    • Vinegar
    • Boiling water
    • Salt (in small amounts!)
    • Allelopathic plants (prevent weeds from forming)
    • Mulch
    • Burning them

    While perennial weeds such as the dreaded dandelion can be unaffected unless the root is pulled up, using one of the above methods should keep the rest of the weeds at bay.

    Is Roundup weed killer safe for pets?

    Roundup is by the far the most popular product for killing weeds and so it’s no wonder people want to know if it’s safe for pets.

    In general, Roundup states that pets needn’t be separated from treated areas once the formula is dry. But we don’t like to just take their word for it.

    However, for a pet-safe version, you still need to look for one which is Glyphosate-Free as not all Roundup products are.

    What happens if pets ingest weed killers?

    Hopefully, it won’t happen, but if your cat or dog shows signs of gastrointestinal upset up to 72 hours after the application of weedkiller in your garden, immediately contact your vet. Take the packaging into the vets with you, and try to identify the weeds that it was used on too.
