does dawn dish soap really kills fleas on dogs?

I have a golden retriever and he has had fleas for about 2 months now and we’ve tried stuff to kill the fleas but its not working. I really want to get rid of them because i also have a guinea pig and don’t want her to get the fleas. I was wondering if I could use dawn dish soap to get rid of fleas on my dog and guinea pig.


  • FRONTLINE/ADVNATIX is no longer advisable. Fleas have become immune to it. they adapt well. Frontline doesnt work on my dogs. Found out the hard way. GOOGLE it. Dawn is the only thing i use. Diatomaceous Earth powder is another solution but use with caution, read the labels, and wear gloves/masks. it kills on contact by eating through the fleas shell & attacking the nervous system. I use it regularly BUT i’m concerned about the long term effects on my lungs. I sprinkle DE on my carpets and upholstery. Borax also works well for sprinkling on furniture/carpets. Just keep on carpets for a few weeks of the flea life cycle, then vacuum. Borax/Salt mix will dry up the fleas in the home. Apple cider vinegar works well when added to your pets water however, my dogs dont like the smell or taste so they wont drink it :[ This works by making your pets blood taste like ACV which will repel the flea. These are my suggestions for natural pest control. Thank you.

  • Blue Dawn dishsoap DOES kill the fleas, but I would only reccomend it if the dog is too young for things like frontline. Vaccum your rug often if you are in the same boat I am with a very young puppy with fleas. As soon as the dog is old enough give it a more traditional flea medicene.

    Take it from somone stuck in the position I am if you need to rescue or find a puppy with fleas take it to a shelter. Cute puppies get adopted it is NOT worth the risk and stress to your home, self, and other animals.

  • Found fleas on my dog this morning, dawn mixed with apple cider vinegar works to kill them too. Read it online somewhere, I filled the tub with warm water, mixed some vinegar & blue dawn, and lathered him up really well left on for 5 minutes, rinsed good, and there were dead fleas in the tub. I did wash his face with baby shampoo. Started with the face then used he vinegar / dawn mixture from neck down. After he was dry, I put a water/ vinegar mixture on the brush & brushed his hair & let it dry. Read fleas don’t like vinegar. It’s been hours and no fleas. Today was the first day I noticed any fleas, my dog is white, white and they showed up very good. Hope they are all gone, hate them! Now applying frontline!

  • I tried flea shampoo, flea drops, flea collars and even a 50/50 mixture of vinegar and water. Nothing would kill those fleas and my house ended up smelling like Easter egg dye. I saw a blurb somewhere about using Blue Dawn dish soap (only the blue) to wash your dog, and then a 50/50 mixture of soap and the water sprayed on furniture and other surfaces. I was at my wits end, and figured, what the heck…worst case scenario, I can use the soap for other things if it doesn’t work.

    Within 15 seconds of applying the soap (totally not exagerrating) dozens of fleas began to surface in my dogs fur (the white parts that I could see on anyway). I kept rubbing it in and started to see blood as their outer shells were disintegrated. It kills them so fast and does not have harmful poisons that many other flea meds have. Defintley try the BLUE Dawn dish soap before wasting your money on flea treatments that just won’t work and can harm your buddies!

  • My dog is allergic to frontline I have used dish soap and it did kill the fleas …you have to make sure to wash their head well they all hide there!
