Just the word “fleas” is enough to have any dog owner cringe, and nobody wants their furry friend to suddenly be scratching themselves more than usual. Not only is it unpleasant to know your dog is full of bugs, but a flea infestation can also be very difficult to get rid of unless you know what you are doing.

It isn’t only your pet that needs to be sanitized, but you will have to make sure you take care of the whole house and yard, as well as any area or item the dog has been in contact with. A flea and tick infestation will come back unless you get rid of all flea larvae and eggs also outside in the yard, and for that, you need the best flea killer available, and you will preferably also want it to be safe for your dog.

Grass, fleas and the outdoors can be a bad combination and they reproduce fast but don’t worry, as the following products will help you regain flea control in your own backyard.

Best Flea Killer for Yards Buyers Guide

Getting rid of fleas is difficult, and not necessarily because they are difficult to kill, but because they are stubborn and reproduce incredibly fast. You need to tackle the issue from all possible angles at once, by showering your dog with anti-flea shampoos, sanitizing your home, your dog’s bed, and toys, and dealing with the yard.

If doing only one of these things, your battle against the flea will likely fail, as the dog will get his or her bath, and then walk out into an environment where fleas still exist and become infested again. It quickly becomes a vicious circle and an impossible fight, so whatever you do – don’t forget your yard as you declare war on fleas.

Type of Product

There are many different types of flea kill products on the market today, and you have a surprisingly wide selection to choose from, making it easy to find the right product for you and your yard.

Sprays. One of the most common (and perhaps best) ways to deal with large infestations is to use a liquid that you mix with water, and that is then evenly distributed across the yard or outdoor space. This will ensure you deal with the problem directly, and that it will kill any fleas that are already present and drive the rest away. An easy way to apply a product like this is to add the liquid to a spray bottle and spray it directly on the surface where you want it, or you can opt for a pre-mixed product that comes with a spray bottle.

Traps. A flea trap might not be sufficient for keeping your whole yard flea-free, but it is a great complement to, for example, flea spray. After you have treated and sprayed the whole yard, use one of these traps in areas of extra importance, like where you have dinner with your family on the porch, or maybe close to the dog house (if you have one)? Traps will physically attract flees and ticks and trap them inside a device, and should preferably be kept out of reach from pets and children.

Ultrasonic. These work by emitting an ultrasonic sound that drives away fleas and ticks, and it is completely safe for humans (both adults and children) and pets. You plug these into an electrical outlet somewhere outside for it to activate. Be sure to check the range of the product you are considering before making your final decision, to establish it would be effective for a yard the size of yours, and start enjoying the many benefits of a device that drives away fleas, ticks, rodents and more.

Mulch. Covering your backyard with mulch is a whole different approach to keeping fleas and ticks away! While the material is not in any way toxic to these creepy crawlers, it is not an environment they tend to thrive in, and as a result – they will generally choose somewhere else to settle down. Use mulch in your yard as much as you can, or in your dog’s dog house, as it is also a material most dogs tend to love due to how comfortable it is to lay in, and how great it is for running around and playing. The best thing of all? Mulch only needs to be changed every few years

How Easy It Is to Use?

How easy it is to use a product matters, as you need to be able to use it the way it was intended for it to have the proper effect in your yard. Many products come with a hose attachment so that you can easily get going with your flea killing mission, and all the best products should come with instructions for how to apply the liquid or for how to use the flea repeller in question. If a product is easy to use, you are likely to use it more often, and this will significantly reduce the risk of your home becoming infested with fleas again.


Check the product description to see how long the product you are considering will last, and whether it is necessary to reapply more than once. Some products will only be effective for a couple of weeks, while others could offer protection that lasts several months. There is always the risk of a low-quality product being washed away if it would suddenly stop raining, so this is also something you need to investigate – is your yard protected even if it rains, or will you need to reapply the product to keep the yard bug free?

For All Flea Life Stages?

When comparing spraying products and other flea killers, you will quickly begin to notice that there is a difference depending on which one you choose. Some will only kill adult and fully developed fleas, which is far from the best option when you are trying to control a plague, and you need something that will also get to those microscopical eggs and larvae.

Almost all the best products will kill and eliminate both fleas, larvae, and eggs, but there are a few lower-quality products you might want to avoid, as they tend to be effective on either one or the other.

Natural vs. Chemical Ingredients

When you are a pet parent, you want to try and go as natural as possible, and to avoid any harsh chemicals that could harm your fur friend. The products recommended in this article are all considered safe for pets, and most are made with a very high percentage of natural ingredients. Essential oils are great for repelling and even killing fleas and other bugs, so there is really no reason for you to turn to hazardous chemicals when treating your yard.

True, nobody wants fleas all over the yard and it is easy to freak out and want to turn to the strongest possible chemical – something that will deal with it fast – but this can be harmful both to you, your family, your pets and to any plants and/or vegetables you have growing in the yard, and you are better off with a natural yard product.


Getting fleas to leave your yard alone does not have to be as stressful as you think, as there are now many natural products that can be used (both in the yard and inside the house) without putting your health or that of your dog at risk. This means you won’t have to worry about your pooch ingesting the flea killing product, and you can continue making use of your yard also after applying a product.

That said, even a product that is deemed safe can have a negative effect on a pet or a human, as some may be more sensitive than others, so you should always consult a veterinarian if you notice any changes in your dog’s behavior after having used a flea killer in an area where the dog occasionally spends time.

Expert Tip

Set aside a whole day to properly deal with a flea infestation, and work on both the flea-infested dog, the inside of the house and the yard simultaneously, to prevent a reinfestation.

Did You Know

Only about one in a hundred fleas are ever visible to the human eye, which might mean that if you have seen one flea in your yard – there could be 99 others hiding out there.
