  1. Mow Your Lawn
  2. Get Rid of Excess Water
  3. Use Diatomaceous Earth
  4. Kill Fleas With Insecticide
  5. Use Cedar Mulch

1. Mow Your Lawn

To kill the fleas in your yard, start by mowing your lawn and disposing of any roughage that may be on your lawn. This will drastically reduce the size of their habitat and make your lawn remarkably less interesting to any pest, including fleas, as they will have fewer places to hide.

2. Get Rid of Excess Water

Fleas also need access to water to thrive, so you'll want to remove any sources of water from your yard. If you have standing pools of water or mud puddles, get rid of them. Any method you use will be a good one. Some go so far as to resurface their lawn, but this should only be a last resort.

3. Use Diatomaceous Earth

Diatomaceous earth is another great flea treatment for your yard. Just spread a thin coat of diatomaceous earth all over your lawn. Diatomaceous earth, or DE, as it’s more commonly called, is one of the most effective insect killers in the world. It’s non-toxic and kills fleas quickly and effectively. Additionally, fleas also cannot develop an immunity to diatomaceous earth.

4. Kill Fleas With Insecticide 

While diatomaceous earth will kill the fleas living on your lawn, you'll also need to target other vegetation. The best way to do that is to spray it down with a flea-killing insecticide. If you have vegetation growing near your house you'll want to target that specifically or even consider clearing it out completely so that you have nothing growing within 6-12 inches of your home.  

5. Use Cedar Mulch

To help prevent fleas from coming near your yard again, spread some cedar mulch around. Cedar mulch is an effective flea repellent as fleas (and most other insects) hate the smell of cedar, and will avoid it. Spreading cedar mulch will help you get rid of fleas in your yard permanently. 

hash-markWhat Attracts Fleas to Your Yard?

Fleas are attracted to tall grass, animals (mice and rats), and wet environments. Fleas are fairly simple creatures when it comes to what attracts them. They love the things all wildlife enjoy, namely food, water, and overgrowth. They want to be near animals that they feed on, stagnant pools of water, and tall grass they can leap off. More specifically, fleas tend to congregate around areas that have rodents like mice, rats, and rabbits. If you have a lot of these critters living on your lawn, they will attract fleas.

hash-markHow to Use Insecticides to Kill Fleas in Lawn

There are a ton of highly effective flea killers on the market right now, and any single one of them can be used with great success. When choosing an insecticide, keep the following in mind:

Ensure It Targets Fleas

When you’re shopping for an insecticide for your flea problem, it’s important to make sure that it kills fleas. Some types of insect killers are geared more towards ants, termites, or other pests. The only way to make sure your poison will be effective is to see that it’s been labeled for fleas.

Protect Pets

If you have pets, keep them indoors for at least four to eight hours after spraying down your yard. This prevents them from getting sick from the poison.

Consider Natural Insecticides

People who have young children, pets sensitive to pesticides, and sensitive skin need to stick to natural insecticides like diatomaceous earth (DE). These are far less harmful to the environment.

Be Cautious with Delicate Plants

Gardeners who have delicate flowers or foliage (such as roses) should opt for a more natural approach. Harsh chemicals can burn leaves and kill off bugs that help your plants, such as ladybugs.

Follow Instructions Carefully

Always follow the instructions that come on the insecticide’s packaging, even when it comes to the use frequency the company suggests. Overusing certain insecticides can kill your lawn!

How Often Do You Need to Use Insecticide to Get Rid of Fleas?

You should use it at least twice a week if you’re using diatomaceous earth. Fleas hate the stuff, but it can be prone to washing away or blowing away with the wind. To ensure that the fleas get gone for good, the best thing you can do is to double up on pesticides.

hash-markWhat Plants Repel Fleas?

Cedar trees and Fleabane daisy do a great job repelling fleas, but there are many other plants that will repel fleas. Planting these near your home, in your gardens, and around the border of your yard will help prevent fleas from making your yard their home:

1. Cedar

Cedar trees are a godsend for anyone who has a flea, tick, or ant problem. The strong odor of the wood repels most bugs. Since cedar mulch is popular, you might not need to plant cedar to make it work for you. 

2. Fleabane Daisy

With a name like Fleabane, you can expect to see fleas stay away from this plant. You might know this plant by its more common name, Pennyroyal.

3. Citronella

Citronella is well known for repelling mosquitos, but did you know it also repels fleas, too? It’s true, and that should be reason enough to make sure that these citrusy plants have a place in your home.

4. Catnip

Catnip is a treat for your furry friends and a known natural flea repellent. Even sprinkling it around your yard can yield some temporary results. We strongly suggest using it if you want to have a pet-safe plant that can also help keep your cats from being bitten.

5. Lavender

If you have almost any type of insect problem, it’s safe to say that you probably need to plant some lavender around your home. Along with being highly aromatherapeutic, this plant’s scent also has the perk of repelling fleas.

6. Eucalyptus

Another plant that will repel fleas is eucalyptus. Eucalyptus repels the vast majority of bugs, not just fleas. However, if you want to plant this tree, make sure that you don’t have any dogs or cats that wander around your yard. It is highly toxic to them.

7. Rosemary 

Rosemary is commonly used as an herb, but it is also a fantastic flea repellent. Truth be told, almost any major herb you find in your kitchen likely has some kind of anti-flea properties. Rosemary, sage, chamomile, and sweet bay all work under this umbrella.

Where Should You Put Flea-Repelling Plants?

You should put flea-repelling plants around your home. The number one thing you want to avoid happening with fleas is getting them in your house. Once they’re in your house, you’ve got a very difficult problem to solve.

Some of the better places to put your flea-repelling plants include:

  • Windowboxes
  • Along pathways
  • Ceramic pots on your porch
  • Around your home’s perimeter
  • Anywhere you have pets that roam

How Effective Are Plants at Repelling Fleas?

Plants are not as good at repelling fleas as insecticides, but they can drastically cut down on the number of pests that you have. In some cases, planting the right flowers and herbs can actually get rid of fleas altogether

Plants are good, but you should make sure that you have other forms of flea protection alongside them. When choosing the plants that you put around your yard, make sure that they are pet-friendly if you have critters.

hash-markWhen Should You Call an Exterminator?

Truth be told, if you have fleas in your yard, you usually have other pests as well. Thankfully, fleas are fairly easy to get rid of as long as you know what to do. However, some situations strongly suggest that it’s time to ring up the exterminator. These include:

Livestock Infestation 

You have livestock that is regularly getting bitten by fleas. This is a serious issue that can cause your livestock to become a danger to your family.

Persistent Flea Infestation

The flea infestation you have doesn’t go away after regular treatments with insecticide, careful lawn maintenance, and new flea-repelling plants. A pervasive infestation often means that there’s a reason behind all the fleas coming to your home.

Avoiding the Hassle

You genuinely don’t want to deal with all the work that comes with an infestation. Admittedly, taking care of a flea infestation in your yard is something that no one wants to do. If you can afford to have someone else take care of it for you, by all means, do.
