DIY Mosquito Repellent Recipe with Mouthwash, Epsom Salt, and Beer

The effectiveness of the combination

Unleashing the power of a mouthwash, Epsom salt, and beer combination may sound unconventional for mosquito control yet delivers a surprisingly effective DIY solution. This unique blend confuses mosquito smell sensors because of its potent aroma and distinctive ingredients.

The key lies in the precise proportioning: one-third of each element ensures optimal effectiveness. Mouthwash works as more than just stabilizer; it emits strong scents that mosquitoes dislike.

On the other hand, Epsom Salt, reputed to promote lusher greenery without harming your yard or local bee population, pulls double duty in this mixture. And beer—known to attract mosquitoes—is cleverly exploited here as an effective trap within our repellent spray strategy.

Despite its unusual composition, countless users have testified about the efficacy of this homemade concoction for mosquito prevention and control.

Proper proportions and preparation

To create an effective mosquito repellent spray using mouthwash, Epsom salt, and beer, it is important to follow the proper proportions and preparation process. Here is how you can do it:

  1. Gather the ingredients: You will need 1/3 cup of mouthwash, 1/3 cup of Epsom salt, and 1/3 cup of beer. Make sure to use a mint-flavored mouthwash as mint has been known to repel mosquitoes.
  2. Mix the ingredients: In a spray bottle, combine the mouthwash, Epsom salt, and beer in equal proportions. Shake well to ensure that all the ingredients are thoroughly mixed.
  3. Let it sit: Allow the mixture to sit for at least a few hours or overnight. This will give enough time for the ingredients to blend together effectively.
  4. Apply the spray: When you’re ready to use the mosquito repellent spray, simply shake it again and apply it generously onto your skin or clothing before heading outdoors.
  5. Reapply as needed: Depending on your outdoor activities and exposure to mosquitoes, you may need to reapply the spray every few hours for maximum effectiveness.

Does the Mouthwash, Epsom Salt, and Beer Trick Really Work?

Scientific evidence and studies

Scientific evidence and studies have been conducted to determine the effectiveness of homemade mosquito repellent sprays. While there is limited research specifically on the combination of mouthwash, Epsom salt, and beer as a mosquito repellent, individual ingredients have been studied for their insect-repelling properties.

Epsom salt has been found to be effective in deterring pests like slugs and snails due to its high magnesium content. However, there is no concrete scientific evidence supporting its effectiveness against mosquitoes.

On the other hand, beer is known to attract mosquitoes rather than repel them. It contains compounds that mimic human scent and can draw mosquitoes closer. Therefore, using beer in a mosquito repellent spray may not be an ideal choice.

Mouthwash acts as a stabilizer in the homemade mosquito repellent spray but does not offer any inherent mosquito-repelling benefits according to scientific literature.

While anecdotal evidence suggests that this DIY concoction may help keep mosquitoes at bay, it’s important to note that results can vary based on factors such as climate conditions and personal susceptibility to mosquito bites.

When considering natural alternatives for mosquito control, essential oils like lemon eucalyptus oil have shown promising results in repelling mosquitoes. Other methods such as citronella candles or bug zappers can also provide some level of protection against these pesky insects.

It’s worth mentioning that professional-grade mosquito repellents with proven efficacy are available on the market if you’re seeking more reliable protection against mosquitos.

Alternative Natural Mosquito Repellent Solutions

Essential oils

Essential oils have gained popularity as natural mosquito repellents due to their powerful scent and insect-repelling properties. Certain essential oils, such as citronella, lavender, and peppermint, have been found to effectively repel mosquitoes when applied topically or diffused in the air.

These oils contain compounds that confuse the smell sensors of mosquitoes, making it harder for them to locate humans or animals to bite. Additionally, essential oils like lemon eucalyptus oil and garlic puree have also shown efficacy in keeping mosquitoes at bay.

So if you’re looking for a natural alternative to chemical-based mosquito repellents, essential oils may be worth considering.

Citronella candles

Citronella candles are a popular and effective natural solution for repelling mosquitoes. The strong scent of citronella oil, which is derived from the leaves of the lemongrass plant, masks the attractant scents that mosquitoes use to find their targets.

When burned, these candles release the fragrance into the air, creating a barrier between you and those pesky insects. Citronella candles are easy to use – simply light them up in your outdoor area and let them work their magic.

They provide added ambiance to your evenings while helping to keep mosquitoes at bay. So if you’re looking for a pleasant-smelling way to ward off those annoying bugs, give citronella candles a try!

Bug zappers

Bug zappers are another popular option for mosquito control. These electric devices attract mosquitoes with a light source and then zap them with an electrical current. However, while bug zappers may seem like an effective solution, they actually have limited effectiveness when it comes to reducing mosquito populations.

The reason for this is that the majority of insects killed by bug zappers are not mosquitoes, but rather beneficial insects such as moths and beetles. Additionally, studies have shown that bug zappers also attract other pests like flies and gnats.

So, while bug zappers may provide some relief from mosquitoes in small areas, they are not the most reliable or efficient way to combat these pesky insects.


In conclusion, the DIY mosquito repellent recipe using mouthwash, Epsom salt, and beer may offer a natural solution for repelling mosquitoes. While there are claims of its effectiveness, it’s important to understand that homemade sprays can vary in their efficacy and individual experiences may differ.

Exploring alternative natural mosquito repellent solutions such as essential oils, citronella candles, or bug zappers can also be considered for effective mosquito control.

Stay proactive in protecting yourself from pesky mosquitoes by finding the best method that suits your needs.
