Best Flea Killer For Your Yard Buying Guide

Before we take a look at how to deal with a flea infestation, it is first important to establish why fleas are so dangerous. So, let’s take a look…

  • Flea bite dermatitis

This is the biggest problem fleas provide for pets, and they provide a number of them! Flea bite dermatitis is a specific allergy to flea saliva. If your pet has this, they can suffer from intense scratching and itching, which is incredibly uncomfortable for them.

But it gets worse, as the skin then breaks open because they have been itching so much, and this results in a scab being formed, which can get infected. This can happen on any part of your pet’s skin. Nevertheless, you are most likely to find this on the base of the tail and the back.

  • Internal infections

Not only do fleas cause a wide range of external issues, including skin irritation, but they can also cause internal infections too. Tapeworm infection is a prime example of this. If your pet ingests a flea, they can suffer from tapeworms, as the tapeworm is actually inside of the flea and then it begins to grow inside of your pet. Signs of tapeworms include weight loss and an itchy rear end. Anemia is another type of internal infection your bet may suffer from due to flea infestation.

  • Human risk

As mentioned, fleas do not only pose a risk to your pet, but they can have a negative impact on your health as well. While fleas do not live on human hair or skin, they can still bite humans, and if the flea is carrying a disease, you can end up catching the likes of cat scratch fever or the plague.

Now that the product section is over, you still may be having some questions about which flea treatment is best for your yard. Well, this is the section where we hope to clear up anything that may still be on your mind. There are plenty of further points of consideration that we will break down here, before discussing why a flea spray is a worthwhile thing to use in the first place. And then we have our frequently asked questions section closely following behind to cover any remaining issues.

What to Consider When Buying a Flea Treatment for Yard

Now that you have an overview of all the different flea and tick yard sprays, there are a few considerations that you will want to make in greater detail. Here are just a few of them.

  • Ease-of-Use

When you are clearing your home of fleas, you want to do so in the most efficient and effective way possible. So, it is worth looking how easy each of the sprays is to use. Many can be used with a garden hose or have their own host applicator of some description. What you find easiest to use is up to you.

  • Duration

Another crucial piece of information is exactly how long the spray will continue working for. Many last somewhere between three and four weeks, which should be enough time for you to clear your home of the outbreak.

  • Coverage Area

You need to think about exactly where you are planning on using the treatment. Do you have a small or a large yard? If it is the latter, you will need a bigger supply that can be applied across a larger area.

  • Effectiveness

Another point that you need to know is the effectiveness of the spray. Some will only work on the adult fleas but not the eggs and larvae. This means that it is likely that you are going to have to spray again. Other sprays will take action against all of the above, but these are also likely to be the more expensive option.

  • Natural or Chemical Ingredients

Next on the consideration list is whether the spray uses natural or chemical ingredients. Flea sprays containing chemicals tend to be the most effective ones, but there are also some effective non-toxic sprays available too. Always read and follow any instructions carefully to eliminate any risks.

Why You Should Use a Flea Spray for Yard

Clearing your home and pet of fleas is only the first step to take. If you have not got to work on your yard too, you have only done half of the job. If your pet has favorite areas that they like to go on a regular basis, there is every chance that the fleas are within 50 feed. There are a couple of main reasons why you should use a flea spray for your yard.

  • Convenience

Spraying your yard for fleas is an easy way of getting rid of them. There are plenty of sprays that can be used across a host of different surfaces. Generally, you don’t have to spray the whole yard area – you can simply focus on the bits where your dog likes to go in particular. It is the warm shady spots that you should be targeting. Those with a lot of sun exposure don’t require the same treatment.

  • Effectiveness

The other main reason why people rely on these flea sprays for their yard is that they are so darn effective. As you can see from many of the past reviews, the best sprays have an extremely high effectiveness rate on parasites such as ticks and fleas.

How to Check Your Yard for Flea Infestation

As you can see, a flea infestation is the last thing you want to have in your home, for your sake and your pet’s sake. So, how can you tell if you have a problem with fleas? Here are some tell-tale signs that you should be looking out for…

  • You can see them: Let’s start by pointing out the obvious; if you can see fleas, then you have a problem! Fleas are flat and they don’t have wings. They are roughly 2.5 mm in length, they have six long legs, and they jump far.
  • Your pet is irritated: If your pet is scratching excessively, there is a high chance that they have a problem with fleas. This is especially the case if their skin is red and they have lost hair. For cats, the neck and head are the most commonly targeted areas. For dogs, their hindquarters are most commonly targeted.

Here are some unmistakable signs that your pet is suffering from a flea infestation…

  • Flaking skin and scabs – like dandruff deposits
  • Pale gums or anemia
  • Hair loss
  • Bumps and welts
  • Powdered deposits
  • Restlessness
  • Itching and scratching
  • You have been bitten: Another sign that you could have an issue with fleas is if you have been bitten yourself. If you wake up in the morning and you have small red, itchy welts from flea bites on your body, it is probable that fleas are the cause of this. You should check your socks, floor, sheets, and anywhere else that your pets like to hang out to see if there are any specks. These specks could be dead fleas or eggs, and again, this indicates a flea problem.
  • Use water and heat: Another effective method for determining if you have a problem is by attempting to attract fleas with heat. You need dishwashing detergent, warm water, a bowl, and a lamp. Simply fill the bowl with warm water and add a bit of detergent to make it a little bit soapy. Place the bowl on the floor and shine the lamp over the water. The fleas will be attached to the light and jump towards it. So, what is the water for? Well, the fleas will jump into the water, and the soap will kill them, so you not only discover whether you have a flea problem, but you do a good job of killing several in the process.

Best Ways to Kill Fleas in the Yard

There are many different ways that you can kill fleas if you have a problem in your yard. The easiest way is to use one of the products that are featured in the next section. However, there are some other approaches you can use too.

  • You can use diatomaceous earth, typically shortened to DE, which is widely used to kill pests, including fleas. The good thing about this approach is that there is no risk of injury or sickness to humans or animals. This product appears like sand – they are tiny grains with sharp edges. The edges are sharp for fleas, as they are so small, but they aren’t a problem for humans. So while they will hurt your pesky pests, you can be sure that you won’t be at risk.
  • If you are trying to get rid of fleas in your garden, aside from spraying insecticides, another option is to flood your yard. This can help to kill fleas because it will kill the larvae and eggs. This will help to make certain that future generations of these small and irritating pests are stopped dead in their tracks. Of course, you don’t want to turn your yard into a lake, so do be mindful about how much water you use.
  • Another option is to use a flea trap, which is an electronic device. These traps produce a warm light, which has the purpose of luring the flea. The trap that is set up will do the business in terms of getting rid of the fleas.
  • Flea bomb – Last but not least, you can use a flea bomb, but this is an approach that should most definitely be used with caution. This is because it involves using poison to deal with fleas, which most certainly is not a great idea if you have pets.

How Soon Will You See Results?

So there you have it: some of the best products you can use to get rid of the flea problem you are experiencing at your home. However, you may be wondering how long it will take for these products to work their magic. Of course, this largely depends on the product you have chosen, and so it is best to look at the specific instructions to get a better idea regarding how long it will take for the spray or granules to work their magic. Of course, some of the products, for example, the electronic device, will offer immediate action, and you should start to notice results instantly. For other products, you may need to wait between 24 and 48 hours. Please note that you will also need to apply the product continuously, usually every four weeks, but again this does depend on the flea killer you have chosen, in order to ensure you keep the pests at bay forever.

Best Flea Killer For Your Yard FAQ:

Q: What is a flea control for yard and how does it work?

A: A flea control for your yard comes in a liquid, chemical format that you can spray over your yard to kill adult fleas. Some also kill eggs, larvae, and pupae too, but these ones tend to be more expensive. Most sprays last around three or four weeks, but the cheaper ones will be washed away by rainwater. Some come with their own hose attachment, while others need to be used with a garden sprayer. Check the bottle for more information on the places you can use the flea control, but many can be used on lawn, deck, and patio areas. Some can even be used inside as well.

Q: Are flea sprays for yard safe for pets?

A: Of course, you should always check the instructions and warning labels closely before determining how safe the spray is for pets. With some, you will need to remove your pet from the vicinity first before spraying. You will need to wait until it dries before bringing your pet back into the yard area. With others, they are made of natural ingredients, so you can use them safely around your pets.

Q: How do I apply a flea treatment for yard?

A: The method of application varies from treatment to treatment, but it is generally easy. Some come with their own hose attachment for spraying around your garden. Others need to be attached to your own garden sprayer. Read the instructions beforehand, so you know exactly what you are buying before purchase.

Q: How long does a flea killer for yard last?

A: Again, this varies from flea killer to flea killer. Generally, the answer is between three and four weeks. Obviously, the longer duration of the best yard sprays for fleas and ticks means that you will have to spray your yard less frequently. But these ones are also likely to be more expensive too.
