Step-by-step instructions on how to create mosquito killer liquid at home!

Simple Soap Water
Take a bucket and fill it with water. Add soap to the water, about one tablespoon of detergent for every gallon of clean water. Mix well until you get bubbles.
This solution will be used as mosquito killer liquid at home by being sprayed on an area where mosquitoes are usually seen or can easily be found such as low lying plants, bushes etc.
And the best way to use this simple soap water as a mosquito killer will be : spray on the stagnant water around your house.
The soap will reduce the surface tension and thus mosquitoes will drown.
In India we do have a lot of places around our houses with stagnant water, especially around drains.
And the soap water is an easy solution to spray in monsoon until the municipality starts to spray chemicals or you yourself do it.
Garlic kills Mosquitoes!
Just mince two cloves of garlic and cover with about 200 ml of mineral oil. Let it sit at room temperature for a day, then bottle the oil in a spray container along with 2 cups of water and fresh squeezed lemon juice. Keep away pesky mosquitoes by spraying them with this mixture.
You can also spray it around the walls and places where you suspect the mosquitoes will be.
But this requires some time to prepare and probably is not the best way.
Baking Soda Mosquito Trap
You can also try a simple, safe homemade solution to protect yourself from mosquitoes: mix baking soda and water in equal parts.
And you can keep the mixture away for multiple usages. Place part of the solution in any container that has enough space to let mosquitoes get inside.
If you want, add some ground ginger and/or cloves for an extra mosquito-fighting punch.
The baking soda is really good at killing them before they have a chance to bite you while the water helps keep it from sticking together. It
Yes, you do not need to spray this homemade mosquito repellent since it will attract the mosquitoes away from you.
Thus do not keep it with you.
Citronella oil
Citronella oil is a great mosquito killer or repellent. There are many incense sticks available made from it. You can also mix it with water, lotion or oil and spray on your skin.
- Add 1 cup of citronella oil to a 1000ml water or less
- Mix well and pour into a spray bottle
- Shake before each use
- Spray on skin or clothing for repelling mosquitoes
- This recipe will last 2-3 weeks, but you can always make more if needed
- Citronella oil is also great for making candles and cleaning the house!
For the sake of easy usages I use the citronella sticks. Usually one stick will burn for around 30 minutes. and the repelling effect will remain for around 4-5 hours.
Lemon eucalyptus oil mosquito repellent
- It’s important to use a carrier oil (olive oil) when making this recipe, as the lemon eucalyptus is very strong and can irritate skin
- You’ll need 5-10 drops of lemon eucalyptus for every ounce of carrier oil
- Add the two ingredients together in a small jar or bottle, then shake vigorously
- Apply liberally before going outdoors during mosquito season
- Be sure to store your mixture in an airtight container away from direct sunlight and heat sources
- Store at room temperature; do not refrigerate or freeze! (this will cause condensation)
Use camphor to repel mosquitoes also
Camphor is a natural insect repellent, You can use camphor to repel mosquitoes and other insects
Camphor can be used in many ways, such as burning it or rubbing it on your skin. Rather than applying on skin burning it would work better.
For burning you can use machines or just light them up.
There are machines that exactly look like a refill vaporizer and you need to plug them in to use them.
Get a good one from amazon here, otherwise you risk burning the machine up.
Camphor has been used for centuries to ward off bugs and pests. Another easy way to use it is to put camphor on a water bowl.
The water slowly evaporates and the camphor with it.
This is a very slow process but works to keep mosquitoes away.
For best effects I would suggest that you use citronella oil, citronella sticks and then use camphor.
And if you have a severe mosquito problem like us then you have to use these chemical mosquito killers.
The best way to store camphor is in an airtight container away from heat sources like the stove or fireplace.
Homemade mosquito repellent vinegar
Although not so useful, mixing up vinegar and water might help you repel mosquitoes. This combo works for repelling/killing ants also.
Mix equal amounts of white vinegar and water and put it in a spray bottle. And spray near the places where you suspect mosquitoes will be.
This is probably the easiest homemade mosquito repellent.
The best ways to use Lavender in your home or garden for mosquito control
Lavender and some other herbs make a great mosquito repellent spray!
Here is what you can do!
Fill a container with water and pour in dried lavender flowers before putting the container on top of your stove for six hours.
During this time it is important to keep stirring the mixture as it will be thickening up, or alternatively you can make the solution without drying the lavender beforehand if you want it to retain its vapourising properties. Once cooled down you can spray it around your house to repel mosquitoes and other bugs.
You can also mix lavender with essential oils such as peppermint oil, citronella, Oil of lemon eucalyptus and cayenne pepper mixed together in equal proportion will keep bugs away from your house or garden without being harsh on the environment.
There are also plenty of different ways to use lavender around the house or yard to ward off mosquitoes. You can either plant them as a living fence around your property line or fill up pots with them (spreading them out across windowsills is another great idea).
But lavender and other plant based mosquito repellents become too costly very fast.
