3 Homemade DIY Flea Sprays for Dogs

Last updated:

Looking for DIY flea spray to knock out fleas this summer? We’ve got your back (and your pup’s) with our list of easy recipes to kill fleas fast!

We all know that feeling — the overwhelming dread that comes when you see your dog start scratching. You take a look and notice tiny, black critters crawling along their back. OH, NO!! You probably already know fleas can multiply by the hundreds in just a day, leaving you with an infestation that seems never-ending.

You likely already know that the best way to treat fleas is a visit to the vet for prescription-strength flea medication, too. But what can you do in the meantime? What about the fleas in your home? If your dog’s got ‘em, figuring out how to handle dog fleas takes the top spot on your priority list!

That’s where these awesome homemade flea sprays for dogs come in handy. You can use these recipes directly on your dog’s coat and around your home.

Remember, fleas don’t live out in the open. They’re not partying on your living room rug… but they’re UNDER it. Fleas like to lay their eggs in dark places where they can hatch and jump (up to 100 times their body length and two feet into the air) onto their target.

You’ll need to spray under the couch, stove, fridge, rugs, entertainment center, etc. Don’t forget around all the baseboards too, especially if you have carpet. That small space between the carpet and the wood is the perfect home for fleas.

What home remedy can I use to kill fleas on my dog?

You’ll find many options to kill fleas on your dog around the internet. Unfortunately, some of those options just aren’t safe. Take essential oils, for example. Pet Poison Helpline published an article about essential oil toxicosis that explains exposure to these substances can result in liver damage, difficulty breathing, and seizures.

While cats and birds have a higher risk, dogs can still suffer from these effects. Other, more common side effects include vomiting, lethargy, and chemical burns (if skin is exposed).

The reality of home remedies posted on the internet is that they may or may not be safe for your pet. Extensive research should be done before using anything recommended by those who aren’t veterinary professionals. SidewalkDog spoke to Carley Wigley, a veterinarian at Heartland Veterinary Partners, about natural ways to kill fleas.

She said, “Natural remedies don’t really work. The only thing we recommend that works quickly in a pinch is bathing with Dawn dish soap. The soap cuts through the greasy, protective layer fleas produce on their exoskeleton and suffocates them. But it only works for fleas that are on your dog. So, after the bath, fleas can come right back.”

With that in mind, let’s check out some homemade flea spray recipes that might give your dog some relief while they wait to see a vet.

1. Vinegar and Water Homemade Flea Spray

One of the easiest recipes for dog owners to use is a vinegar and water spray. Take equal parts apple cider vinegar and water, mix them well in a spray bottle, and mist your dog. You’ll likely have to reapply every few days for maximum effectiveness. Overall, both apple cider vinegar and white vinegar are safe to use around pets and children, even if they lick it. But make sure to keep it away from their eyes since vinegar is acidic and might damage them.

2. Lemon Juice Homemade Flea Spray

Lemons are sour and acidic which is very unappealing to fleas. You can mix half a cup of fresh-squeezed or store-bought lemon juice with two cups of water to create a natural, nicely scented flea spray. Similar to the vinegar spray, avoid spraying around the eyes and reapplying often is necessary to keep the fleas at bay. Lemon juice can also leave stains on furniture and clothing.

3. Skin So Soft Homemade Flea Spray

Originally launched back in 1961, Skin So Soft Original Bathing Oil was intended for women to use in the bath or shower for softer, more supple skin. However, due to the presence of picardin (a chemical pesticide), some people have used it as a flea repellant on their dogs. 

The EPA (Environmental Protection Agency, USA), states picardin has a low risk for toxicity. The fact sheet the EPA published in May 2005 about the chemical states that picardin “has low acute oral, dermal and inhalation toxicity.” So, it’s generally safe to use on and around your pets.

Start by bathing your dog as you normally would. Towel dry, then combine the Skin So Soft oil in equal parts with water in a spray bottle and shake well. Spray your dog’s wet coat all over and gently brush it through their fur. Allow your dog to air dry. Some people like the smell, but you’ll have to decide for yourself. According to some, this method lasts for about one month. But it does leave an oily residue on your dog’s coat. Don’t get it in your dog’s eyes, as it may be irritating and cause conjunctivitis.

The Bottom Line on Homemade Flea Spray for Dogs

While a natural remedy might help for a short time, it’s not going to end your fight with fleas. The best way to treat and prevent fleas is to visit your vet for a prescription designed to do just that. There are many products out there that have been proven both safe and effective in dogs. Treating your home is especially important for severe infestations. Products like Ovitrol might have you running out of the house due to the smell but are generally considered safe to use.

If you’re desperate for a homemade flea spray for dogs,  be wary of recipes with potentially harmful ingredients. Many online resources recommend using essential oils which can be super dangerous for your dog. The ones we’ve included above are safe for you on and around dogs. Also, with any flea spray, be sure to protect your dog’s eyes as these ingredients could cause significant damage.
