If your pets are like mine running around outside in the yard then wanting back in 5 minutes later, like a couple of little kids. The chances are good that they are picking up fleas and bringing them into your home.Fleas are attracted to animals by there body heat and there breath.Mainly co2 gas as they exhale.Also vibrations as they run and explore the outdoors. Using borax in the yard may be an alternative, instead of buying an over priced name brand . Borax twenty mule team  is nothing more than laundry soap additive.Which is not bad when compared to a man-made flea poison. The only draw back to borax the fleas in your yard is  keeping your dog(s)  off the lawn for at least 24 hours .You could always take them to the park for the next day or two.

First clear the yard

Pick up everything you can out off the yard ,that you don’t want borax on. As you will be spreading it everywhere your pets hang out,run and do their business.As borax is a very dry powder you want it to be as dry out in the yard as possible. With no chance of rain for the next couple of days. What I have done in the past is to break up the yard into sections,where I do only the front yard and let then out back and vise verse. Also at this time I always mow the grass.  I drop the blades down one notch lower than I normally would to get as close to the fleas as I can. This also helps ,because you will not be on your yard for a few days.

Applying Borax to the yard

You can go about this in a couple of ways. You can spread it around the yard by hand ,wearing gloves of coarse. or a jar made into a large salt shaker. I don’t like to use the jar,because when your hand sweats its hard to hand on to.What I do like to use is a lawn spreader for seeding and feeding your grass.You can find cheap ones at lowes or home depot for around $20.00 dollars. Just remember to wash it out with clean water when are are done.

After you have given the borax a day or two to work. The last step is to rinse off the yard with a garden hose or sprinkler ,this will knock the remaining borax down into the soil . I always wait a few hours before I let them back in yard, just to let the water dry up.

Well that’s all there is to Borax for Fleas in Yard. Good luck and if you have any questions drop me a line.

    I found a remedy with apple vinegar and borax to bathe my dog. Which is the safest way to bathe him or take care of it? I have spent $$$ to the vet and he has stopped the bald spots but not the itch. My poor dog itches all night, not much in the day time. We fogged the house, car, yard, mattresses in the house…I will do anything to help him!!!

    • Iam not sure ,what is it you need?

    • there may be something bringing in the fleas, like us, we found out there was rats in our crawl space and attic. you may want to see if that is a possible reason

    • My dog was driving me crazy with itching day and night. Then I used Epsom salt bath. For 7days boy I can sleep now…. I have a small dog so I used 1 1\2 cups and lukewarm water. For 10 minutes every night for 7days. Hope it works for you.

    • Are you certain it’s fleas? Mange is not uncommon, and causes bald spots in addition to itching. My dog had a bout of mange and I bathed her with neem oil mixed with baby shampoo, followed by a rinse of a solution of borax and lemon juice in water and let air dry. A couple of these treatments along with supplementing her diet with healthy oils, ie, coconut, palm fruit, flax, etc. did the trick.
      Also many dogs have allergies that most traditional vets don’t test for that will cause similar symptoms.

    • after putting the boax on them, bathe them in dawn and rinse off completely. the dawn is going to dry out their skin and make them itch even if they don’t have fleas so use some conditioner on them to cure the dry skin itch.

      Just spread it like you were feeding birds in the back yard, a light coating. If you can keep them off the grass for two days, then hit it with a garden hose to wash in into the soil.

    I would like to know if there any precautions needed for vegetation? Thank you

  4. Hi there! Thank you for this website! I am hoping this works for me, finally! I did the borax & hydrogen peroxide on my dog (He had mange, I’m making sure it stays gone. Got him on a better diet & it seems to be helping) and rosemary, lavender, neem oil, neem oil shampoo, etc etc even some pyrethrin crappy junk toxic dip things.. all to no avail. Everyone keeps telling me it’s in my house.. OMG you have to use Diatamaceous Earth, DE to get rid of them. I tried that twice. Nada. I left it down for a week & vaccuumed. Did it again, vacuumed.. nada. I don’t see any fleas in my house at all. None on me etc.. I wash my dogs. They get clean,fleas all drown, they have to go out to potty. They come in with fleas. I live very very near the woods & they say every bug has it’s year. I think this is the year of the flea. What is funny, is one dog has fleas. One doesn’t have any. One goes outside a lot & follows me around out there gardening. One hangs out on the couch all the time. No fleas on him, but he is still itching like mad, hence the mange mention in the beginning of the post.
    I think the borax thing is finally gonna do it. I am also going to buy pert in the morning. TY again! I will update everyone!

    • let me know how it works out

      Borax works great in the house….just sprinkle it in and vacuum as usual. It is effective for a year. You won’t see results immediately but the fleas fade away. Borax doesn’t kill fleas it interrupts their reproductive cycle. I have used it for years in the house.

  5. Hi. How long do I leave the box outside my small infested front yard for? I have mix the borax with salt hearing it will double the effect. Is that a ok or not ok solution? I can’t even take a step outside without being attack. Please please help me! Need a answer.

    • You just need to spread it on the yard it will do all the work.I have not heard of mixing it with salt.

    • if you’re so ignorant that you can’t figure out you need to spread it in the yard then you should live with the fleas.

      Darwin Award winners…wow

      • bathe them in dawn after the borax and rinse off completely. the dawn is going to dry out their skin and make them itch even if they don’t have fleas so use some conditioner on them to cure the dry skin

  6. I have a yard full of dirt n weeds dirt mostly after I’m done mowing. Will the borax work the same n dirt.

  7. Hi, I’m visiting my dad in Florida and he has 4 small dogs that are suffering miserably! His house, yard, and dogs are infested with fleas. If the dogs can’t go outside for 24 hours after spreading borax on the lawn than what can or should i do for inside the house where they spend most of there time? I’m at my wits end with this and would spread borax all over this house just to kill these micro invaders!! Help meeee…

    • This is what Iam using outdoors this year. Diatomaceous earth. I am working on a article about it.

      • Hi Michael,
        I heard about DE and spread it all over the house a while back already but it didn’t work for us. I have made a mixture of flea shampoo that contains pyrethrin and bleach to wash the floors with and that seemed to work! I also shaved 3 of the dogs that have long hair and flea bathed them. The fourth dog is a min pin so he has short hair….lucky dog gets to keep his hair lol. Let me know what you think of that idea!

  8. Our rabbit runs wild in the back yard and he eats the grass. If I put this on my lawn and wait, water it when it’s all done. Well it hurt my rabbit when he eats the grass?

    • This is what Iam using outdoors this year. Diatomaceous earth. I am working on a article about it.

      • Michael …….please be very careful with diatomaceous earth it is dangerous. If this is inhaled by your pet in anyway into their lungs it will kill them . Diatomaceous earth is essentially small microscopic pieces like glass shards that will shred their lungs. It will present as a severe upper respiratory and upon x-rays, will reveal lung distruction that is irreversible. This happened to a good friend of mine who’s cat was hospitalized and had to be put on oxygen , was suffering so badly that sadly her cat had to be euthanized. Please don’t play around with this you never know what little areas your pet sniff into that may be an innocent oversight of accumulated powder in your yard . And putting it anywhere into your house where they lay down and sniff the floor is just putting your pets in peril.

    Ok, my dog has fleas, I have bathed,dipped,rubbed,sprayed,bombed,& powdered this dog and house, I have not tryed the Borax, but lord know I sure will, thank you very much, but I have two big dogs out side, and I can’t keep them out of the yard for two days they won’t stay on a leash, or even keep a colar on their neck. I can’t get them in the car it’s to small. My naboir has two big Rott’s,and they don’t even like my dogs and will Tara them up and kill them. My little dog throws up when riding in a car, and dramameen don’t seem to help. What can I do.?? About the fleas in the yard?? If the dogs have to stay in the yard. I tryed to bring them in the house, they tore everything up trying to get back out the house. They don’t like to be inside at all. Help if you can.

    • I have used Borax in the yard before. It’s okay as long as it doesn’t rain for a couple of days. What I did try this year was diatomaceous earth. Works on the same principle as borax. I know Lowes sells it and some of the bigger hardware store do. Give it a try. Good Luck

    • Well, the only thing I can tell you is to buy cedar chips that people use for there hamster bedding and spread them all around your yard. That way you won’t have to keep your big dogs in the house for two days. Fleas don’t like cedar and it won’t harm your dog’s! Good luck! Also as far as your dog that gets car sick….sound like a case of anxiety. Ask your vet if they have doggie xanax that you can give to your dog.

  10. I have fleas on my balcony two floors off the ground….how can I kill them?


  1. […] city mail you a box. If you checked the store locator hopefully you can get your hands on a box of borax for fleas and start to rid your home of theses unwanted invaders. Time and time again I have used this […]
