Pour 3 cups of water in a spray bottle. Add 1 teaspoon of dishwashing liquid in it to help spread the water evenly on the surfaces you intend to spray it on. Mix in 1 tablespoon of peppermint oil. Give the spray bottle a nice shake. Spray this solution on all the possible places where you expect the spiders to be. Repeat once daily for a few days.
Soak cotton balls in peppermint essential oil and place them in the cracks and gaps around doors and windows. Change the cotton balls daily until you stop noticing spiders in your house.
You can even grow peppermint plants in your kitchen garden.
3. White Vinegar
White vinegar is another efficient natural spider repellent.
Just like peppermint, spiders hate the strong pungent smell of white vinegar. It will drive away all the spiders in no time. Its acetic acid can even burn and kill spiders upon contact.
Moreover, this nontoxic method is safe for you as well as your pets.
Mix equal parts of white vinegar and water in a spray bottle.
Spray this solution on any area where spiders can hide.
Also, spray it directly on any spider you see.
Repeat once daily until the spiders are completely gone.
It has microscopic razor-sharp edges that can abrade the skin of a spider when it walks over or through it. Once cut, the fluid leaks out of the spider’s body, which causes the creature to dry out and ultimately die.
Put a fine layer of DE around cracks, corners, windowsills, basements and anywhere else you expect spiders to be.
Also, lightly spread DE around the perimeter of your home to keep spiders from coming in.
Repeat once daily until all the spiders are gone.
Note: Do not wet the DE or it will not work.
To do away with spiders, you can even use eucalyptus. Spiders do not like its strong smell and they will soon start looking for a new residence.
Both eucalyptus leaves and essential oil can be used to drive away spiders from your house.
Put fresh or dried eucalyptus leaves in your closets, drawers, shelves or any other place where you suspect having spiders.
Spray windowsills and entryways with a solution of ½ cup water and 20 drops of eucalyptus essential oil.
Apply a few drops of eucalyptus oil in the corners and cracks and other spider-prone areas.
6. Horse Chestnut
To deter spiders, you can also try horse chestnuts. This is a popular old wives tale that happens to be effective. Horse chestnut shells contain a chemical that is toxic to spiders.
Poke holes in some horse chestnuts or split them in half to release their odor.
Place them in each corner of the house and in places where you frequently notice spiders.
Instead of horse chestnut, you can use chestnuts, walnuts or the fruit of the Osage orange tree.
Though it sounds weird, tobacco is another secret weapon to show the door to spiders.
These creepy creatures simply cannot tolerate the smell of tobacco and this discourages them from entering the house.
Soak 1 to 2 tablespoons of tobacco in a cup of hot water for about 30 minutes. Strain it and mix the juice of 1 lemon in the water. Spray the solution all around the house.
Put chewing tobacco in areas where you have noticed these pests in your house.
Repeat daily until you are sure that your house is free of spiders.
One efficient and natural tool to eliminate spiders from your house andprevent further infestation is salt. Another plus point is that it is an inexpensive as well as readily available solution.
Dissolve 1 ounce of salt in 1 gallon of warm water.
Stir until the salt dissolves completely.
Pour the saline mixture into a spray bottle.
Spray the solution directly onto a spider to kill it.
