Our kittens had fleas. There were only 10 weeks old and the spray I had was for 12 weeks and older so I knew I couldn't use it on them. I called the veterinarian near us and they said to use Dawn dish soap to bathe them in. I had 2 small wash tubs. One filled with Dawn and warm water and the other warm water to rinse them in. They didn't seem to mind it at all. Then I went over there bodies with a soft brush to get the feces from the fleas and the dried blood by their ears washed off. The kittens are white so it was easy to see the fleas. I tried to pick the dead fleas off their skin. Then I patted them with a towel. This worked very well. The fleas seems to die instantly.

Why buy expensive dog shampoos at PetSmart to bathe your dog? My vet suggested I use any baby shampoo, so now I buy $1.00 generic baby shampoos at the Dollar Store and I have a dog that smells as good as a freshly bathed baby for a fraction of the cost.

Just thought I'd share this here. During a summer camp hosted by a college, one of the science professors shared a cool lesson with us. They showed us how to create a safe wasp killer. As you know, commercial wasp killer are so poisonous.
He diluted about two tablespoons of Dawn dish soap in a cleaner bottle full of water, shook it, and then we waited for the bubbles to clear. He sprayed it on some wasps, and slowly they died. Other soaps worked, but not quite like Dawn. He said the Dawn creates a very strong film which coats the simple breathing holes of insects and they then, unless there's a source of warm running water, die of suffocation.
Perhaps this is why Dawn makes an effective flea bath. It's not the water rinsing them away, it's the Dawn suffocating them. Fleas are an insect.
Tip on ridding your pets of fleas! My daughter is a professional dog/cat groomer. When fleas are a problem at her shop, they use a dilution of lemon Joy dishwashing liquid. Take about 1 and 1/2 inches in the bottom of the original bottle and then dilute it with water to fill to top again. Shampoo your pet, using care not to get it in their eyes. Lather them well! You may bath them with your favorite shampoo after the initial Joy bath and thorough rinse! Works like a charm!

Dawn Dishwashing Soap is a very effective way of ridding your dogs and cats of fleas. Don't ask me why, but if you wash them with it and leave it on for 5 minutes, the fleas will just fall off when you rinse them.

Sometime the best deals can be found online. Here is a 90oz bottle of Dawn Dishwashing Liquid. If you use Dawn often, this is definitely a great deal.

Hi Hey You,
I found this post while looking for instructions on how to use dawn on your dog to kill fleas. I called my vet about a sudden onset of fleas, late in the year, and he advised me to try dawn.
I have found very mixed results about whether to use it or not, but being as my vet recommended it, I feel that it is probably safe, if used in a pinch and not really often (no more than once every 2 months since it will strip the oils that dogs need on their skin).
What got my attention in your post was how you said to never use baby shampoo on your pet. I own a pug who is very prone to hot spots and dry skin. I tried about a dozen different pet shampoos that advertised they were good for dry skin and hot spots, and my poor buddy got no relief.
I asked my vet and he suggested to try baby shampoo. I invested in a bottle of Johnson's baby shampoo for hair and body, and it has been a life saver. He no longer has the dry, flaky skin, and hasn't had a hot spot in over a year now.
I bathe him with it about once a month, and not only does it cure the dry skin, but it also gives him a soft, healthy looking coat, and keeps him smelling nice almost all month. It has been an absolute lifesaver for me and my little man.
I am not sure why your vet, or the vets at these conventions, say that you should not use it, because mine did tell me to, and it is great. I'll never use a different shampoo on him. I guess vets are just like doctors; none of them agree on everything.
Can I use Dawn dish soap on my cat? He is an 8 year old tuxedo.

I'm certain this would be perfectly safe. During the oil crisis in the Gulf, the original blue Dawn was used to clean all the poor animals that were full of the sludge water. Our vet for our shih tzu recommended the original Dawn to bathe her in. She was allergic to all the flea/tic removal products. It worked out very well.
I have Dawn Ultra. It is not the normal Dawn so I'm worried if what they added to the Ultra Dawn is unsafe for cats.

Dawn or Joy necessary or any non-detergent dish soap? Palmolive is great for our hands, so? Putting dishwashing liquid in watering water works great for plants...even in yard.
Can I use normal dishwashing detergent to get rid of the fleas on my kitten instead of using Dawn detergent?
By Lizzyanny  02/07/2015
Your detergent will get some fleas. Dawn will get them all.

Mix a little vinegar in it and it is better and this was on a post on here a couple of weeks ago and it works better and faster and none of the critters live.
We bought an 8 week old Malipoo and she has fleas and eggs, because every time we kill them and then check her again she will have baby fleas. Will Dawn dishsoap kill the eggs too?
By Jamie Ruth Hubbard S. 09/12/2015
I agree with the first answer you got. However, trying to kill fleas outside is a pain, a real big one. You can choose to go buy a chemical spray for your yard, but I don't like chemicals. But, if you go to your local Walmart, Home Depot, etc...wherever they sell those chemicals, you can find those empty bottles that connect to your water hose for you to spray your own mixture. I have used that by mixing water and Dawn liquid dish soap, then spraying my yard with it. The only downfall to it is if you spray too much (using more soap) it will kill the grass too. Depending on how much soap you use determines how much of your grass dies. A small amount turns it awful brown, more than that can strip it down to just about dirt. But hey, you get to start fresh with no fleas, and it's as good as round up, so no more weeds either, just pretty grass. Hope this was helpful.
I have 2 nine year old inside only cats that have attracted fleas from somewhere. I have given both baths with an organic oatmeal and vinegar based flea shampoo for cats, but they still have fleas. My vet suggested that I make a mixture of apple cider vinegar, Dawn, and water, and bathe both kitties and then add to sprayer and spray entire house, carpet, and furniture to end my flea problem. Has anyone ever tried this and if so how much of each and did it work?

Yeah you can buy Wal-Mart drops, if you want to use toxic poison in your house! There are many reasons to NOT use those drops!
If you have small children that will be touching the animals often, no!
If you have a herding breed that might have the genetic disposition for being deathly sensitive to normal doses of things, no!
If you have someone in the house chemically allergic or sensitive, no!
If you've ever watched Chemerical, you definitely know, no!
I'm even cautious to use Dawn! Why? Because I know those chemical warnings are no joke!
How much Dawn soap do I use to put on my carpets? And does it work and how often can I use it?
By Joyce M. from Pittsburgh
By Sandi/Poor But Proud  08/29/2014
Linda is right. Salt is the best. Now, here is where any dish washing liquid comes in handy.
Fleas love warm climates so they will hop into a pie plate of water sitting under a night light or desk lamp. With a few drops of DWL to break up the surface adhesion they will jump in and drown.
I hope this helps too!
I bathed my new 6 week old puppy in Dawn because I heard how well it worked, but all the fleas ran to her nose. What can I do?

By Echo M. 11/06/2013
When you bath your puppy or dog always start as far forward towards the head as you can. You can start the bath by just doing around the ears, back of the pup's head and then the neck without putting the pup in water. What I do is mix water and dawn in a measuring cup and then soap up around the ears and neck area before putting them in any other water.
As soon as you put the animal in water the fleas will run for "high ground" which is the head. After getting the neck area soaped I then do the rest of the body making sure that they are fully wet and completely soaped up. Scrub and leave soap on for at least 4 to 5 minutes, then rinse.
I have heard of using Dawn blue dish detergent for fleas. What do I do, and does it work fast for relief? My Chihuahua was given Capstar yesterday, and it made him worse. Please help.

Here is the website I found that gave specific instructions on how best to use dawn on your pet to kill fleas. Just be sure to only use it sparingly, and in a pinch, so you do not strip your pet of essential oils in his or her coat. Good Luck!
Does it dry out their skin because my dog has very dry skin?
By DCA  01/18/2015
Dawn removes oil and grease from dishes and it will also remove oil from a dog's body. So do not use Dawn on your dog. If you want to kill fleas and prevent future problems, check with your vet on what to use to avoid dry skin problems for your dog.
How often can you wash your dog using Dawn soap for fleas? daily? weekly? etc. Thanks!
By Sandi/Poor But Proud  10/11/2014
You and your dog will get sick of a bath daily. Weekly too. You are depending on the dawn for the fleas death. It's not what kills them, it's the water. So, here is what works.
Put a pie tin of water under a night light or lamp to keep it warm. Drop a couple drops of any dish washing liquid in to break up the surface adhesion in the water. They jump in and drown.
Give your dog Brewer's yeast tablets available at most stores. This makes their blood undesirable to the fleas and they go elsewhere.
Can I mix Dawn and water and do the inside of my house using a garden sprayer?
I know I can use it to give my dog a bath, but would it be effective at all as a spray as well?
I've found, on the internet that Dawn dishsoap is a good remedy for fleas. However, I am wondering how often should I bathe my puppy Mahina, with it per week. I don't want to bathe her all the time because I've heard that bathing her a lot is actually bad for her and what about the eggs? Does it help get rid of them as well?

How long does it take for Dawn dish soap to kill dog fleas?
By Ce  06/24/2013
I use Dawn full strength on my two girls. The fleas start dying as you are shampooing your dog. Remember to always start with the neck so the fleas don't escape to the ears and nose. If you can keep the lather on your dog for 5 minutes the better. Keep the soap away from the face. I have bathe my dogs once a week to be sure there are no survivors. The soap is very gentle and works great.
Doesn't putting Dawn in your carpet cleaner to help get rid of fleas make the carpet very "soapy" and sticky? Do you have to re-clean the carpet to rinse it?
By Catherine L.
By kbatch04 06/12/2013
I to tried dawn in the steam cleaner only to find I had soapy carpet. I had to rinse it after I was done.
Try just putting a little flea soap like you would use on the animal in your steam cleaner. There is no need to rinse and it kills all the fleas and eggs.
We were so over run with fleas that I would have tried anything and my friend said that's how she got rid of the fleas that had invaded her carpet. So I tried it and it worked like magic.
Does it matter which Dawn I use to bathe my dog? Blue, scented, etc.?
By Bev from MA
By PENNY K  10/02/2012
I'd use the plain blue, but put a few drops in a large plastic glass or container and dissolve it before putting in on dog. It's very concentrated and hard to rinse out and left over soap could make dog itch. Or use a cheap $Tree shampoo, also diluting first.
Does lemon Joy kill fleas?
What is the amount of the mixture of Dawn and water?
By vicki hood  09/07/2011
I never bothered diluting at all. If you wish, half and half should be OK. Get 2 to 2 and a half cups dry Borax into each average size carpeted room. Leave for 2 weeks for life cycle. Vacuum. For the yard use natural, inexpensive Cedercide granules. 5 pounds lasts more than a year.

Can I use Ultra Dawn on my 10 week old puppy? I can't seem to control the fleas. I have sprayed my rugs, etc. Is Ultra Dawn OK? It is all that I have.
I see how Dawn can work, it also takes the oil off of flea's larva. But my question is, will using Dawn deplete my dog's natural oils that his coat needs.
We have used two kinds of flea chemicals on our cats over a 2 week period, but they still have some. They are not scratching much now, but they are licking. I have stripped my bed twice now, but I am still seeing the fleas. How do I use Dawn to get rid of the fleas?
Please help us.

In order to kill the fleas in a room do you use both Dawn and apple cider vinegar in a dish and put it under a light, or is it just Dawn in the dish with water?

Thrifty Fun has been around so long that many of our pages have been reset several times. Archives are older versions of the page and the comments that were provided then.
I read the thread about using Dawn for washing the dogs to get rid of fleas. This is kind of a silly question but does it matter which kind of Dawn you use. I have the antibacterial apple. Is this ok?
By Peggy Z
Do NOT use Hartz anything. The EPA has ordered them to stop producing the product as it has killed so many companion pets.

If fleas are a problem for your pet, wash them with Dawn dishwashing soap. It kills them instantly. Leaving a small nightlight on during the night will draw fleas. Just put a small bowl of Dawn under the light and they will jump in. By Brenda from Cleveland, OH

Does dawn dish soap really work on dogs that stay outside all the time? What is the best thing to use on my yard because the fleas have been bad here and Sevin Dust did not work.
I read that you can give your pet a bath in original Dawn soap to kill fleas. I just did it right now and a lot fell off.
