    The Top 5 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


    • Weight: 1.1 Kg
    • Size: 1L

    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

    Roundup Naturals Glyphosate-Free Powerful Weed Killer

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

    Roundup is a household name. You can’t go wrong, and you’d be mistaken if you thought this meant it wasn’t safe for pets because of the strength. It contains a 100% natural active ingredient, is glyphosate free and gives visible results in just one hour.

    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.

    Golden Swan White Vinegar, 5 Litre x 4


    Honestly, we’re not messing around here when we tell you that vinegar is the way to go if you want to kill your weeds in an all natural fashion!

    Originally a cooking and pickling liquid, Golden Swan’s White Vinegar has gained a reputation for being one of the best cleaning and weed killing solutions on the market, and is now the best-selling white vinegar brand on Amazon!

    Despite only having a concentration of 5%, Golden Swan has been proven to kill weeds while having absolutely no potentially harmful effects on pets or children.

    Coming in a four pack of 5 L bottles, it’s also the most economical option out there, costing a fraction of the price of most weed killers, for literally 20 times the amount of solution!

    To pump up its effectiveness, we recommend mixing a full bottle with a couple of handfuls of salt and a cup of washing up liquid to help neutralise that vinegar smell!

    Just pour the mixture into a spray bottle and you’re good to go!


    • 20L mega pack
    • Great ingredient for homemade solutions
    • Add salt and washing up liquid for eco-friendly weed killer

    RHS Ready to Use Weedkiller Glyphosate Free

    For those who are all about a glyphosate free concoction, RHS’s Ready To Use Weed killer is an advanced biodegradable formula offering two 1L spray bottles in one pack.

    This is one of the best deals on the market given its strength, with each bottle harbouring an impressive 60g of acetic acid per litre, giving you great control over annual and perennial weeds.

    It’s a non-selective solution, meaning you need to be careful when applying it as it will kill most soft plant tissue it comes into contact with.

    However, it’s important to note that this formula is only good for controlling weeds. It will not kill the plant roots and so re-treatment over the growing season is necessary.

    This means applying the killer more often and that best results are only really achieved against weeds of 10cm or less.

    Still, if keeping your pet safe and healthy is more important than zapping your weeds away first time, it’s a lot less dangerous than the average chemical solution!


    • 2 x 1L Sprays
    • 24 hour results
    • Effective all year round


    • Weight: 2.2 Kg
    • Size: 2L (x 2 pack)

    Buying Guide

    Does Pet Safe Weed Killer Really Exist?

    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.

    The most common chemical agents found in weed killer are:

    • Glyphosate
    •  2, 4-D (Trimec)
    • Sethoxydim

    The most common of these is glyphosate, as it is a chemical associated with being the fastest and most effective at treating weeds. It is a complete herbicide that destroys all plant life and so you’d need to be careful when applying it, as it would wipe out any nearby flowers and shrubs too!

    Some of the most popular weed killers in the world such as 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.

    Whether glyphosate weed killers are actually safe for pets or not is something that is often disputed, as the current data surrounding their effects is not large enough to draw a concrete conclusion.

    However if you value the health of your pet above all else, there’s enough to suggest it isn’t the greatest option.

    Although there is nothing yet to suggest using such products can be fatal, there are suggestions it can make pets quite ill.

    Levels of glyphosate in weed killers are actually so low that it’s unlikely to be toxic for animals, and given how abundant the use of Roundup is, we’d probably be suffering from an international pet death pandemic if this was the case.

    However, the surfactants used in combination with the glyphosate in order for it to effectively penetrate into plants are what can become irritants to animals.

    If eaten while wet, it can cause skin irritations and gastrointestinal upset.

    This means if you can keep your pets out of the garden while the weed killer dries, they are probably fine to use, but this can be very difficult, especially if you own cats!

    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.

    Features To Look Out For


    If you can find a glyphosate free product, it’s likely to be far less harmful if accidentally ingested, as some of the surfactants needed for it to work will no longer be included.

    However, this is likely still going to have things in it which aren’t 100% healthy for your pet, and so it’s recommended you keep them away from gardening areas after it’s use until things dry

    Vinegar Solutions

    It sounds bizarre that you can kill weeds with vinegar, but when you remember vinegar is often used as a homemade cleaning tool, it’s perhaps not so surprising.

    This is not the kind of vinegar you chuck on your salad or chips either, so put the balsamic down before you go dressing those weeds with a nice drizzle.

    You’ll instead need to look out for solutions containing at least 10 – 30% for it to be effective.

    For our money, it’s undoubtedly the ultimate form of pet-safe weed killer.

    Weed Removing Tools

    Rather than pouring chemicals all over your garden, why not physically remove weeds with a weeding tool?

    These days such devices are far more advanced than a simple root puller, with weed burners being a particularly good choice.

    Although it’s slightly more effort, it’s a superb eco-friendly option which doesn’t require you to keep your pets at bay!

    Other Buyers Ask...

    How do I use weed killer safely around pets?

    The methods we’ve included in our definitive 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.

    Keeping Pets Inside

    If you want pets to be safe and weeds to be efficiently killed, the easiest thing in the world to do is just keep your pets indoors and wait til the solution dries.

    This would prevent almost every case of a pet licking or eating wet weed killer and so hunting down pet safe products wouldn’t be an issue!

    Wait 24 Hours

    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.

    What are some pet safe weed killers?

    As previously mentioned, the idea that there is a truly pet-safe commercial weed killer is a bit of a myth and so you are probably best off using some homemade remedies to solve your weed issue.

    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

    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.

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