How to Make a Homemade Mosquito Spray for Your Yard

Mosquitoes find many different natural plants and even consumable goods unpleasant and will not go near them or any area which has been treated with that product. The internet is full of recipes for homemade DIY insect and mosquito sprays, lotions, and other products, but many of them do not seem to work as well as claimed by their authors. For that reason, in this article, I have gathered some of those homemade mosquito yard spray recipes which have been proven to be efficient and seem to actually keep mosquitoes away.

Mouthwash and beer mosquito repellent

This insect repellent is an interesting combination of ingredients. Since these ingredients can be found in most households and the combination of these two products has proven to be very efficient at deterring mosquitoes, I would give it a shot.

You can spray this mouthwash and beer mosquito repellent throughout the yard and it will last about two and a half months before you will need to re-apply.

You will need:

  • One 16 oz. bottle mint-flavored mouthwash
  • 3 cups Epsom salt
  • 3 stale 12 oz. beer

Place all of the ingredients in a large bowl and mix them together with a spoon until the Epsom salt has dissolved completely. Use a funnel to pour the mixture into a spray bottle. You are now ready to treat your backyard with this homemade insect repellent.

When choosing your ingredients, you might want to go for a mint-flavored mouthwash which is also organic. It is advisable to buy an Epsom salt which is either lavender or eucalyptus-scented, or even both if you can find it. When choosing your beer, go for whichever is the cheapest as any beer will work fine in this recipe.

Apple cider vinegar mosquito repellent

A very simple but efficient recipe for a yard spray is this apple cider vinegar mosquito repellent. Even though the effect will fade much faster than the mouthwash and beer mosquito repellent, it will be just as efficient and will keep the mosquitoes from coming into your backyard for a few weeks.

You will need:

  • 2 oz. water (normal or distilled)
  • 2 oz. apple cider vinegar
  • 20-55 drops of Bug Off Oil (depending on the level of protection you need)

Mix all of the ingredients together and pour the mixture into a spray bottle. This apple cider vinegar mosquito repellent is said to keep mosquitoes from coming into your backyard for several weeks, but once you notice an increase in the number of pests again, you can re-apply the repellent without hesitation. As the mixture is completely safe and natural, it will not harm humans or the environment.

Essential oil mosquito repellent

There are many plants that naturally deter insects and mosquitoes. That is why the essential oils that are extracted from them are widely used in the production of insect repellent products. But you can also use the same essential oils when creating homemade insect repellents. There are many different recipes which are very similar, so you can always substitute one recipe for another or change the ingredients as many different oils will work just as fine. But here is the recipe which has proven to be the most efficient and successful at keeping mosquitoes away.

eucalyptus essential oil


You will need:

  • 3 oz. vodka (or a combination of witch hazel and distilled water)
  • 20 drops citronella essential oil
  • 10 drops eucalyptus essential oil
  • 10 drops catnip essential oil
  • 5 drops thyme essential oil
  • 3 drops neem oil

You can change both which essential oils you use and how much of them you add to the mixture because different combinations will work better in different regions. Even though the recipe might change a bit, the core idea of using natural essential oils from mosquito repelling plants remains. That is why I have included this recipe as one of the most efficient and best at keeping mosquitoes away – even though the ingredients and the amount of essential oils might be different for everybody.

I made a mistake and bought the green mouthwash (spearmint) instead of the blue mouthwash (peppermint) . My question is: Will the green mouthwash still work in place of the blue one? The receipe calls for blue or should I just go out and buy a blue one? thanks


    As long as the spearmint mouthwash smells minty it should be okay. But if it doesn’t then I suggest you go out and buy the peppermint mouthwash.


    Are these recipes cat safe??


    You should especially avoid the third recipe since it calls for using thyme and eucalyptus essential oils, which are considered toxic to cats. But if you’re still not sure if all the ingredients in these recipes are cat-safe, I’d suggest you consult your vet.


i tried the mouth wash beer spray and it did not work seem to not have any effect after you sprayed, while you were actually spraying it worked!!!


    Glad to hear that it worked at least while you were actually spraying the solution in your yard.
