Make Your Own Organic Mosquito Yard Spray

Aside from the annoying redness and itching caused by mosquito bites, in most cases, mosquito bites are harmless. Still, it is no fun being bit by mosquitoes. Try this organic yard spray that is safe for humans and yards.

A gardening friend, understanding my desire to use safe organic products, recently shared this wonderful mosquito repellent with me. The following organic mosquito repellent can be sprayed throughout the yard to repel mosquitoes. Just one spraying lasts for about two-and-a-half months before needing to be sprayed again.

I tried it! It works!



  • Two 24-ounce spray bottles (Or, one bottle that holds 36 ounces)
  • Spoon
  • Large bowl
  • Funnel


  • 16-oz bottle of mint-flavored mouthwash (I used PerioBrite)
  • 3 cups epsom salt (I used lavender and eucalyptus scented)
  • 3 stale 12 oz. beers (I used Budweiser)


  1. Place all the ingredients together in the large bowl and then mix with the spoon until the epsom salt is dissolved.
  2. Use the funnel to pour the solution into the spray bottles.
  3. Spray all around the yard, especially anywhere you plan to be outside.

Note: I found that it is easier to handle the smaller 24 ounce bottle of solution instead of handling the large (heavier) bottle.

This solution will not harm your yard, in fact some gardeners say the Epsom salt helps the grass grow greener. But, I would not spray it directly on flowering plants. Instinct tells me it might be too harsh for the flowers. Mosquitoes will stay away for about two-and-a-half months. That’s almost a whole summer!

Shopping Tips

Spray Bottles: You can find spray bottles at stores like Walmart, however, the easiest place to find spray bottles in just about any size is Amazon. They offer inexpensive and fast delivery.

Mouthwash: Look for a mouthwash that boasts its organic qualities. Make sure it is mint-flavored because mosquitoes do not like the scent of mint. I shopped online and was able to find an organic mouthwash through a health related store.

Epsom Salt: Any Epsom salt will work fine. I just happen to have Epsom salt with lavender and eucalyptus and just used that.

Beer: Do not spend a lot of money on beer because any beer will work fine. I have seen cheap off-brand beer at the Dollar General for as low as 75 cents per can.

The Zika Virus Mosquito

The Adverse Effects of Mosquito Bites

A report issued by The World Health Organization (WHO) provides compelling information about the dangers of mosquito bites, indicating that mosquito bites account for several million deaths every year.

Two prominent health concerns are malaria and the Zika virus.


Aside from the Zika virus, The World Health Organization states that about 3.2 billion people are at risk of contracting malaria, a life-threatening disease caused by parasites that are transmitted to people through mosquito bites of infected mosquitoes.

Signs and Symptoms of the Zika Virus

For signs, symptoms, and treatment of the Zika Virus, read the fact sheet published by the World Health Organization

Zika Virus

As of July 20, 2016, the World Health Organization reported that 65 countries and territories have reported evidence of Zika virus transmissions since 2007, and some of them have been reported in my local area in northern California.

The Zika virus is caused by a virus transmitted by Aedes mosquitos. Common symptoms are mild fever, skin rash, conjunctivitis, muscle and joint pain, headache, and possible death. Some notable complications are microcephaly and Guillain-Barré syndrome and other neurological complications.

Mosquito Bite Allergies

Many authorities, including the American Academy of Allergy Asthma & Immunology (AAAAI) suggest that the most effective solution to ward off mosquitos is to use mosquito repellent products that contain DEET. Personally, I prefer to shy away from using products that contain chemicals of which I am not familiar. However, I am realistic. I don’t like being bit by mosquitoes; at the same time, I don’t like taking chances with my health and well-being. The chance of being bit by a mosquito and contracting a harmful disease outweighs any apprehension I have against using products containing DEET. I am smart and I concede to using products that contain DEET if they are the only solutions at my disposal. It is better to be safe than sorry. And then again, the use of DEET is recommended by authorities who know more than me about how to repel mosquitoes.

Repelling Mosquitoes in the Yard

Gardening is my favorite pastime. I enjoy spending time in the yard. However, nothing ruins that enjoyment more than being bit by a mosquito.

My friend can’t remember where she found the organic mosquito yard spray solution that she has been using successfully for years, but I am happy she shared it with me. And I am happy to share this organic mosquito repellent with you.

Try this organic solution for repelling mosquitoes. I hope it works for you as well as it works for me.

Are Bees Harmed by Beer, Mouthwash and Epsom Salt?

After reading a number of gardening guides, scientific journals, and visiting various forums related to bee care, I discovered that the organic mosquito repellent presented in this article, for the most part, is harmless to bees. Please note: Bees can get drunk from consuming too much alcohol. While the repellent recipe here contains beer, it also contains mouthwash and bees do not like mouthwash, so if you spray this solution in your yard, it is likely the bees will simply stay away from the areas that are sprayed with the solution. Regarding Epsom salt, scientists have discovered that Epsom salt is safe for bees.

        Hi Casey, I read a few gardening guides and visited forums and for the most part, found that this formula does not harm bees. I should note that bees can get drunk from consuming too much beer, however bees do not like mouthwash and simply stay away from the solution altogether. With regard to Epsom salt, most reports that I read indicated Epsom salt was safe for bees. Thank you for this question. I will update this article to include this answer.

        Does this affect bees?

        I have a lot of pollinators in the summer & want to be sure they won't be deterred.

        I live on a river with a run-off stream & have horrendous mosquitos May-Oct usually.

        Hi Audrey, if there are 10 people hanging out in the yard and only one person can get stung by a mosquito, I would be the one being stung. They seem to love me too. This mosquito repellant works really well for me. By the way, aloe vera is an excellent solution to soothe the bites.

        Mosquitos love me! I get bitten all summer long. The bites turn red and swell up something terrible. I've been using aloe vera to soothe these irritated areas.

        Thanks for this organic spray solution.

        Does the beer have to be stale.....and if so, why?....just curious, because I have the beer in hand, but never have stale beer around.

        Hello ChitrangadaSharan. You are so fortunate that you don't have mosquito worries. We have a lot of them around here and so I do all that I can to avoid them.

        A very useful and helpful hub to prevent mosquito related problems!

        We don't have many of them here but I take precautions even if I notice one f them. Mosquitoes cause many diseases and some of them can be life threatening.

        Your organic solutions are much preferable compared to the chemical creams and sprays.

        Thanks for sharing!

        Hello Barbara Kay! They keep talking about a drought here, but I tend not to believe there is a drought because of the number of mosquitoes. I do hope this solution works for you.

        We've had a drought here this summer, so mosquito haven't been a problem. Next year I'll try your recipe. It sounds easiest enough and I have everything on hand except the beer.

        Hi tirelesstraveler. For me, mosquito bites can send me into a very lifeless state of being. I actually get sick, so I am happy to have this solution. And, like you noticed, it is really easy to make.

        Oh, Manitita, regarding the zapper... The mosquitoes are attracted to the zapper and when they touch the zapper they get zapped with electricity. I had a zapper. It works, but it is noisy. Every time a mosquito gets zapped I could hear them frying from the electrical charge, which can get quite annoying over time.

        Hello Surabhi Kaura. Thank you very much for your solutions. I am anxious to try the holy basil. I have not seen it at the nurseries, but you can bet I will be looking for it from now on. Also, I'll be trying the room freshener idea. That's a quick and easy solution.

        HelloMatt Easterbrook5. Living where the mosquitoes enjoy living is no fun. This bottle of spray is one solution that works quite well. But, some mosquitoes seem to be "hungrier" than others so every now and then an aggressive mosquito breaks through and annoys me to no end.

        Hello manatita44. While I don't have a degree or certificate, I could say I am knowledgeable on just about every remedy available for warding off mosquitoes. They attack me with a vengeance and I get really sick whenever I get bit so I have read extensively about them and what I can do to avoid being bit by them. Oh, by the way, the short answer to your condo question is no. And, I'll get more details to you a little later. And, thank you for your compliment. I love being out in the garden.

        Hello billybuc, you are so lucky to live in a mosquito-free zone. Me? I'm not so lucky. The mosquitoes here are extremely aggressive. I'm glad I found a way to keep them away.

        Hello Faith Reaper. I suffer a lot whenever I am bit by mosquitoes. They mostly hover around my husband but they only bite me. I don't like spraying stuff on my body, so I was really happy to find a solution that I could spray around the yard.

        I live in Oregon and we get mosquitoes that are sure annoying when you are trying to relax or BBQ on your patio. I will try this organic solution and I am hopeful it will work as good for me as the success you received in your backyard. I really appreciate the research and time you put into this hub article.

        Great Hub! I did not know that you venture in this area of expertise. I see that some athletes have refused to go to Brazil as problems with the Zika are supposedly rampant there.

        I used to travel a lot. The Germans created something called a 'zapper' for zapping the mosquitoes, or is it zapping themselves. I've forgotton now. I have gone to eleven African countries, perhaps, and others where I would also worry. God's grace I have been ok. I generally take doxycycline or malarone.

        Your garden looks beautiful! Are you still in the Condo? Excellent Hub.

        A pertinent article! And, especially in these weathers when mosquitoes are quite common. I normally get mosquito-bites when I am outside or during the evening walk at the park. Sometimes my loved ones tease me, saying that my blood is so sweet that the mosquitos can't resist. Lol.

        There's an ancient technique that we use to keep them away from our home - holy basil plants (tulsi). Just plant a holy basil plant in your backyard or at the entry points of your home. The leaves are said to kill the mosquito larvae. You can also use lavender-scented room fresheners. I use Lilac Oil and Coconut Oil on my arms and legs. It has anti-bacterial, anti-fungal properties, and it keeps away the mosquitos.

        Interesting points in your hub, especially about the Zika virus. So many new viruses. But then its our responsibility to keep our inner and outer areas neat and clean. Cleanliness is next to Godliness... as the saying goes, aha.

        Thank you for sharing this recipe for organic mosquito yard spray. Here in the Deep South, we have monster mosquitos who seem to love to eat me alive ...My husband can be sitting right next to me and they won't bite him at all, but they attack me for some reason.

        I am certainly trying this good advice out here. Thank you again for sharing. I hope you are well.

        Hello Eric! I get absolutely sick in bed when I get mosquito bites, so it is a serious matter to me. Like you, I am always making sure there is no standing water anywhere near my home. Thank you so much for your positive feedback.

        Really great. We are crazy about not standing water. We have visited Southeast Asia and went crazy with repellent. We are hypervigillante with our young child.

        We love our spiders and other insects but mosquitoes are a no no. This hundred + plus heatwave knocks them dead.

        Very good article to raise awareness.
