Materials Needed to Make Homemade Mosquito Repellent Listerine

Yes, you’ve heard it right. We’re going to make a homemade mosquito repellent made out of Listerine! This is not only great to make our breaths fresher, but it’s also one effective ingredient that you can use to get rid of mosquitoes.

Before you end up spraying the whole bottle in your room, you’ll first have to prepare the materials needed in order to make this amazing blend.

  • 1 Bottle of Listerine – First, a bottle of Listerine is needed as this is your primary ingredient. Mosquitoes hate this because of its eucalyptus scent, making it an effective ingredient for a bug spray. 
  • 3 Bottles of Stale Beer – You can use any beer brand. The cheapest beer that you can find will do. Beer is a great mosquito killer; apparently, something about the smell (thiamine) makes them flee. 
  • 3 Cups of Epsom Salt – Not only is Epsom salt effective in enriching the soil and your plants, but it’s also actually a great addition to any insecticide blend. Just make sure to dissolve it completely so that it won’t clog your spray bottle. 
  • 1 Big Bowl for MixingThis is needed so that you can mix all of the ingredients. Make sure it’s big enough so that you won’t spill the mixture once you start mixing.
  • 1 Spray BottleAny spray bottle will do. Ideally, a bottle with a big spray nozzle is a good option so that you can immediately cover the whole area and do the job more quickly.

Prepare all of these in an area where you’re most comfortable with. You can do this in your kitchen or in your backyard where cleaning can be done easily. After all, this involves a lot of liquids and mixing, so be sure that any spillage happening in the area won’t necessarily be a hassle for you. 

Steps on How to Make Homemade Mosquito Repellent Listerine

As you’re now already prepared, you can start making this amazing homemade blend. Follow the easy and simple steps provided below:

Step 1: Gather all of your materials. Ensure that everything is within reach so that you can mix them smoothly and quickly. 

Step 2: Prepare your basin. Make sure it’s clean. In the basin, pour all of your beer. Wait until the bubbles are gone.

Step 3: Add in the mouthwash. Make sure that you pour all of it inside the basin together with the beer.

Step 4: Stir the mixture until both ingredients are incorporated really well.

Step 5: Add in the Epsom salt. Don’t add it all at once. You can add 1 cup at a time after you mix it and dissolve it really well in the liquid mixture.

Step 6: Keep on mixing until you no longer see any traces of the Epsom salt. This is necessary because you wouldn’t want the salt to clog your spray bottle. Plus, once it dries, it’s really hard to take off and clean, so you’d want it completely incorporated in the blend. 

Step 7: Once you’re certain that the ingredients are blended well, you can now pour the mixture in your spray bottle. You can store the remaining liquid in a separate container or bottle. Just refill your spray bottle when needed. 

This simple blend is definitely easy to use. Plus, it’s not only effective in getting the mosquitoes at bay, but it’s also an eco-friendly method when dealing with pests. Use this mixture as often as you can. After a day or two, you’re surely going to see results.
