How to Get Rid of Fleas in the Yard: Top 10 Most Effective Ways

Here’s the one flea guide you may be missing: how to get rid of fleas in the yard.

Because let’s face it. You’ve done everything else. You vacuum religiously. You’ve treated your pets for fleas. You’ve steam cleaned the carpet and washed everything you own. Your home finally seems clear of fleas.

So, are you safe?

Not exactly – there’s one more step you need to take to make sure the effort you made so far is worthwhile. And you need to take this step…outside.

How to Get Rid of Fleas in the Yard

If your pets like to spend time out in the yard, that’s most like the main source of the fleas that keep finding their way into your home.

The solution? Eliminate the fleas lurking right outside your house so no more of these blood sucking parasites can sneak in through the back door. Literally.

Here’s how to get rid of fleas in the yard – permanently.

Clear out the yard

This simple step can go a long way in your battle against fleas – fleas love to to hide out where they’re protected from bright sunlight such as in piles of dead leaves so start by clearing debris from your yard.

Find the fleas’ favorite spots

Fleas and their larvae can usually be found within 50 feet of your pet’s favorite areas. Look for any warm, shady spots around the yard where your pet likes to hang such as under the porch, below shrubs or along the fence lines.

Your furry friend’s kennel is likely to be teeming with fleas, as well!

Spray a flea insecticide (chemical option)

Using an effective flea insecticide is an easy way to quickly kill off most of the adult flea population lurking in your yard. And you won’t even have to spray the whole yard – just focus your effort on treating the flea-infested places that you found – warm, shady spots. Open areas with plenty of sun exposure don’t need to be treated.

Talstar Pro insecticide is great flea-killing bang for your buck – it’ll wipe out the fleas from your backyard, as well as other pests like mosquitoes and roaches. The active ingredient is 7.9% Bifenthrin, which is a pyrethroid chemical that’s safe for children and pets once dry.

Before spraying, make sure you keep all pets and children indoors and don’t let them back in the yard until the insecticide is dry. Remove all toys and other items that your pets and children use so they don’t get sprayed.

Also protect yourself before you spray as well by wearing a proper mask, gloves, long shirt and pants, and shoes and socks. Try to spray on a calm, windless day.

Note: Keep in mind that insecticide will quickly kill the adult fleas in the yard, but it won’t target the egg, larval or pupal stages of the flea. So if you just spray once and leave it at that, you’ll see a huge improvement in the flea situation…that is, until the eggs hatch and the pupae mature to create another flea infestation.

So if you use this insecticide by itself, you must spray once a week for at least 4 weeks in order to completely break the cycle. 

Mix with an IGR to kill fleas permanently (chemical option)

As we mentioned above, insecticides will kill the fleas in your yard fast, but it does little for the flea eggs, larvae or pupae – which will eventually grow into the jumping, biting adult fleas we all despise.

Well, unless we cut the cycle short with insect growth regulators (IGRs) like pyriproxyfen and methoprene.

These IGRs are a more recent form of pest control that are rarely kill adult fleas but effectively break the flea life cycle by inhibiting the growth and maturation of flea larvae.

When used together with an insecticide that kills adult fleas, you get the most comprehensive way to get rid of fleas – permanently and at all stages of development.

Sprinkle Diatomaceous Earth (natural option)

One effective natural alternative to using chemicals to kill fleas is to sprinkle your lawn with food-grade diatomaceous earth (DE). This will, however, only work if you live where it’s not wet and raining since DE need to be in dry, dust form to work its magic.

Simply apply it to the flea-infested areas by using a dust spreading or tossing handfuls of it on the infested areas. When adult fleas make contact with it, the dust dries out their bodies, effectively killing them in a couple of hours.

Introduce predators (natural option)

Flea larvae are notoriously difficult to get rid of. Wouldn’t it be wonderful if you had something that eliminated them for you?

Meet nematodes.

These miscroscopic worms do to fleas what fleas to do us – minus the itchy bites. Okay, not really – what they do is a lot worse. These parasitic worms basically enter their prey and infect them with toxic bacteria that kills them in 24 to 48 hours.

Their favorite prey? Fleas and ticks.

These killers will hunt down and kill fleas in the pre-adult, pupae, and larval stages of their growth, which account for 95 percent of the flea population.

The best part is that nematodes are a totally nox-toxic (at least to non-fleas) natural way to kill fleas before they even get old enough to bite you or your pets.

Just apply them onto areas where fleas live – preferably out of direct sunlight since nematodes don’t like the sun.

Get nematodes here!

Let the sun shine bright

Both adult fleas and larvae moist, shady conditions so trim branches and foliage away to allow more sunlight to enter your yard. Adults fleas will hate it and the larvae won’t be able to live in a sunny environment.

Water it away

Frequently water your yard also helps get rid of flea larvae since it washes away adult flea droppings, which which the main food source for the larvae. Gross, but true.

Keep out flea-carriers

If your yard is the chosen mingling spot for the neighborhood strays, the fleas will be back in your yard before long. And it’s not just the strays – you’ll want to limit squirrels, deer, rabbits, raccoons, and mice and rats from getting into your yard as well.

Start by patching up any holes in your fences and if you don’t have them already, create some barriers along your property. Also, check under shed and decks and evict any wildlife that have shacked up in your yard.

Lastly, take measures to remove temptations for unwanted visitors. You can significantly reduce your yard’s appeal simply by removing bird feeders, moving uneaten pet food indoors, and  keeping garbage sealed.

A no flea barrier around your yard

To close off your yard from fleas for good, create a barrier around the yard by lining the perimeter with cedar mulch granules. It contains red cedar oil which repels fleas, mosquitoes, roaches, flies, gnats, scorpions and venomous snakes from your premises while smelling lovely.

It’s also organic and safe for you, your pets and your kids.

You can also use it around areas where you pet likes to play and around your house to form a barrier against fleas.
