8 DIY Dog Mosquito Repellent (Effective & Budget Friendly)

Living with multiple pets—dogs, cats, and rabbits—means that I’m always on the lookout for ways to keep them safe and happy. One thing that I noticed over the years, especially with my dogs, is how mosquitoes can be a real nuisance. Not only are they annoying, but mosquitoes also carry the risk of diseases like heartworm. Store-bought repellents can sometimes feel like overkill, especially with their strong chemical smells, which got me thinking: why not try a DIY solution? It’s natural, easy on the wallet, and safe for my pups. Plus, making your own dog mosquito repellent can be a fun, creative project. Let’s dive into how you can whip up a natural, effective solution right at home.

Do Dogs Need Mosquito Repellents?

Absolutely. Just like humans, dogs can suffer from mosquito bites, and these little insects aren’t just a minor annoyance—they can pose serious health risks. For dogs, the biggest concern is heartworm, a parasitic infection transmitted by mosquito bites. Even if your dog is on a heartworm preventive, it doesn’t hurt to add an extra layer of protection during mosquito season, especially if you spend a lot of time outdoors.

DIY mosquito repellents are a great alternative because they use natural ingredients that are safe for dogs (and often for humans too), and you can avoid the harsh chemicals found in commercial sprays. With a few simple ingredients, you can create a gentle but effective mosquito deterrent that’s tailored to your dog’s needs.

DIY Dog Mosquito Repellent: Step by Step

Materials Needed

• Apple cider vinegar: $2–$5
• Essential oils (lavender, eucalyptus, citronella, lemon): $5–$10 each
• Water: Already have this!
• Spray bottle: $1–$3
• Witch hazel (optional): $3–$5

Total cost: Around $10–$20, depending on what ingredients you already have.

Phase 1: Creating the Base

The base of most DIY mosquito repellents is a mixture of water and apple cider vinegar. Vinegar is great because mosquitoes hate its strong smell, but don’t worry, it will fade on your dog’s coat quickly. Mix equal parts water and apple cider vinegar—about one cup of each. This creates a natural, safe base that you can enhance with essential oils.

Phase 2: Adding Essential Oils

Now comes the fun part—customizing the repellent with essential oils. Lavender, citronella, eucalyptus, and lemon are all great for keeping mosquitoes at bay. Add about 10–15 drops of each oil to your base mixture. If your dog has sensitive skin, use fewer drops to avoid irritation. Mix the solution well by shaking the spray bottle.

Phase 3: Testing the Repellent

Before you start spraying your dog all over, it’s important to do a patch test. Spray a small amount of the mixture on your dog’s fur and wait 24 hours to ensure there’s no reaction. If all goes well, you can start using it before walks or outdoor playtime. Just remember to reapply every few hours, especially if your dog is spending extended time outside.

Easy DIY Dog Mosquito Repellent Ideas

Here are some easy-to-make mosquito repellents that are not only effective but also budget-friendly. You can try different combinations of ingredients to find what works best for your dog.

1. Apple Cider Vinegar & Lavender Spray

This is a simple yet effective spray made with equal parts apple cider vinegar and water, plus 10 drops of lavender essential oil. Lavender not only repels mosquitoes but also has a calming effect on dogs. Shake the mixture well before each use and spray it lightly on your dog’s coat before heading outside.

This costs about $5 and is a great starting point for anyone new to making their own repellents.

2. Coconut Oil & Lemon Balm Balm

If you prefer a balm over a spray, coconut oil is an excellent base. Mix it with a few drops of lemon balm oil, which is known for its mosquito-repelling properties. Rub a small amount of this balm on your dog’s fur, especially around the neck and ears where mosquitoes tend to bite the most. The balm can also double as a skin moisturizer for your dog.

This balm costs about $8 and is perfect for dogs with dry skin

3. Witch Hazel & Citronella Spray

For a quick and refreshing spritz, mix one cup of witch hazel with 10 drops of citronella oil. Citronella is a well-known mosquito repellent, and witch hazel helps soothe the skin. This spray can be used on your dog’s coat as well as on your outdoor furniture to keep mosquitoes away from your entire space.

This project costs around $7 and is a dual-purpose spray for both pets and the environment.

4. Lemon & Eucalyptus Mist

Lemon and eucalyptus are powerhouse ingredients when it comes to repelling mosquitoes. Combine one cup of water with 1/4 cup of lemon juice and 10 drops of eucalyptus oil. Shake it up and spray lightly over your dog’s fur. The scent of eucalyptus helps keep mosquitoes away while lemon juice adds an extra layer of freshness.

This spray costs around $6 and is a great natural option for outdoor summer days.

5. Herbal Mosquito Collar

If sprays aren’t your dog’s thing, you can create a mosquito-repellent collar using fabric and essential oils. Take a plain cotton bandana and soak it in a mixture of water, vinegar, and essential oils (lavender, eucalyptus, and lemon). Let it dry, then tie it around your dog’s neck before outdoor adventures. The collar acts as a natural barrier against mosquitoes.

This collar costs about $5 and is perfect for dogs who dislike sprays but need protection.

6. Rosemary & Peppermint Oil Spray

For a fresh-smelling repellent, mix one cup of water with 1/4 cup of rosemary tea (steep fresh rosemary in boiling water) and 10 drops of peppermint oil. This blend is cooling for your dog and naturally keeps mosquitoes at bay. Plus, it’s safe to use on both dogs and humans, so you can spray it on yourself, too!

This costs about $6 and offers a refreshing, all-natural solution for the whole family.

7. DIY Mosquito Wipes

For on-the-go mosquito protection, create mosquito-repellent wipes using paper towels, witch hazel, and essential oils. Soak a few sheets of paper towels in a mixture of water, witch hazel, and lavender oil. Store them in a resealable plastic bag and wipe your dog down before heading out. These wipes are convenient for travel or walks in mosquito-heavy areas.

This project costs about $4 and is ideal for quick, easy applications when you’re out and about.
