Will Jeyes Fluid Kill Moss?

Moss is undoubtedly an unconventional plant. It seems to pop up in our gardens somewhat randomly, whether we want it or not. Admittedly, its aesthetic has a certain charm to it. Plus, it has a host of health benefits.

However, it doesn’t take much for it to spread, and it does so at an incredible speed. 

It may not have a vascular system like most other plants, but it’s arguably the most dominant of them all. For this reason, it’s common to seek its removal. 

In the process, you may find yourself considering enlisting a bottle of Jeyes Fluid to help you out. 

But can it help?! 

Below, I’ve explored whether or not Jeyes can actually kill moss, alongside highlighting a bunch of alternative solutions too. 

So will Jeyes Fluid kill moss? Jeyes Fluid is very effective at killing moss. That being said, Jeyes Fluid has a very high chemical concentration count, making it unsafe to handle and also environmentally damaging.  

Whether it has overtaken your driveway, patio, or any other area for that matter, a mere encounter with Jeyes Fluid will kill moss in a flash. 

But you certainly need to be careful.

So let us now look at how you can safely use it before turning to some other options should you feel that this has since put you off!

How To Safely Use Jeyes Fluid To Kill Moss

Exercise Caution

In other words, be sure to protect yourself.

The handling of such chemicals should not be taken lightly.

Skin contact will unequivocally cause irritation, whilst mouth and eye contact may cause much more serious damage.

Fortunately, by wearing suitable clothing, you can indeed keep yourself out of harm’s way.

Think gloves, long sleeves, long trousers, and maybe even safety glasses and a facemask too! 

Dilute It

By default, Jeyes Fluid has an extremely high concentration of chemicals.

Hence before use, it should be diluted with water.

Not only does the addition of water make the solution much less harmful, but also, a little Jeyes Fluid goes a long way, so why waste it?! 

Spray It

Jeyes Fluid is non-discriminatory, so a good aim is fundamental!

Using a spray bottle to dispense the Jeyes Fluid solution onto the moss will enable you to be much more precise than if you were pouring it.

The extra control will allow you to aim solely for the moss, and you’ll be more likely to keep surrounding plants and other items in good health. 

Check The Weather

Finally, before heading outside to tackle that moss, be sure to double-check the weather forecast.

The aim of the game is to avoid turbulent conditions – particularly that of wind. Such weather threatens to comprise your ability to be accurate.

Wind, for example, could quite easily cause your Jeyes Fluid solution to drift to unintended areas, including back onto yourself. It’s simply not worth the risk!

How Long Does Jeyes Fluid Take To Kill Moss?

Jeyes Fluid will work almost instantly on moss, typically killing it within a few hours. 

Whilst it takes several resprays and even several weeks to kill weeds, Jeyes Fluid generally only takes a matter of hours to kill moss. 

It’s rapid, and you’ll know the moss is dead because its once lustrous green color will have turned shades of yellow and brown. 

When you spot the change in color, it’s time to scrub it away with a garden brush and clean the area with water. 

Is Jeyes Fluid The Best Way To Remove Moss?

It’s clear that Jeyes Fluid is an effective moss terminator. However, whether or not it’s the best way to remove moss is a subjective matter. Whilst some love it for its convenience and reliable results, many find the solution to be much too strong and too much of a subsequent risk to the environment and one’s own health. 

Things To Know When Using Jeyes Fluid To Kill Moss

Protect Your Patio

Jeyes Fluid is so strong that when it’s applied to moss, it also poses a risk to whatever the moss happens to be on top of.

If you have a brand-new patio or one that is made of tarmac, you probably don’t want to risk ruining it with chemicals.

In such a case, your best bet is to patch-test your Jeyes solution on a small inconspicuous section of your patio first.

If it seems too strong, dilute it further until you’re confident that it won’t ruin the ground beneath. 

Similarly, if the moss is growing on your lawn or soil, you’ll want to use as weak of a solution as possible, if any, so as to not deplete the area of nutrients.

Be Mindful of Surrounding Plants

As you spray, be sure not to allow the Jeyes to touch any plants that you wish to keep happy and healthy.

The Jeyes Fluid will hurt them and could even kill them. Move them out of the way before you begin spraying.

If that’s not possible, exercise as much accuracy as you can whilst you apply it to the moss. 

Stay Safe

Cover up and stay safe! Just as Jeyes is a threat to your beloved plants, it’s a threat to you, too, as well as any pets or children you may have.

Keep your skin well-covered whilst you apply it, and keep yourself and any other humans or animals away from the area whilst it’s at work. 

Other Ways To Kill Moss

If you’re not convinced, do not fear!

There are plenty of alternative ways that you can go about killing moss sans Jeyes Fluid.

For ease, I’ve outlined the best of them below. 

Homemade Herbicide

It’s super easy to conjure up a solution from the comfort of your own home.

All you need for it is water and a splash of either dish soap or baking soda. They’re not just effective; they’re safe ingredients too! 

Again, spraying the solution is best. Use a spray bottle or a garden sprayer to dispense the mixture.

It usually takes around a day for the moss to die, after which point you can scrub at it or use a rake to remove it. 


Another eco-friendly solution. All you need is one tablespoon of vinegar and a gallon or so of water.

Once combined, spray the mixture generously over the moss as thoroughly as you can.

It should take a day or two for the moss to die, but if it seems to be taking a little longer, go ahead and respray! 

Control Solutions

If DIY isn’t your thing, you could pop to the local garden store and pick up a bottle of moss control.

There are several brands to choose from, and all you’ll need to do is follow the basic instructions laid out on the bottle.

Of course, I recommend choosing an organic product to ensure you’re doing all you can to preserve the surrounding environment. 

By Hand

Additionally, you may want to consider getting hands-on and digging out the moss.

You’ll need a rake or hoe to help you out, but you won’t need any sort of liquid or chemical solution.

It’s an approach that requires a little elbow grease but one that is sure to evoke a thorough result and a sense of accomplishment.

Soil Check

If the moss is growing over your soil, you may want to explore whether there’s an underlying cause.

In fact, there could be several of them! The truth is the presence of moss isn’t a random phenomenon.

It could be an indication that your soil is low in nutrients. Or it could be too damp or too shaded.

In most cases, you’ll find that the pH of your soil is too high.

Thus, neutralizing your soil will help to gradually reduce the presence of moss, as well as prevent its future growth.
