And/Or:
Apply Peppermint Oil
Spiders hate the smell of peppermint. Fill a spray bottle with water and 10-15 drops of peppermint essential oil and spray in places spiders tend to hide—under furniture, in closets, and in other corners and crevices of your house. In addition, add a few drops of peppermint oil to a cotton ball and strategically place them in trouble spots.
Hide Chestnuts
Chestnuts have a scent that keeps spiders at bay. Place chestnuts around your house where spiders can sneak in. Basements, attics, windowsills, and door frames are prime locations. The best part about chestnuts is that they don't leave any residue behind when scattered around the house.
(
BUT--Your dogs might eat the chestnuts and/or the cats might play hockey with them. )
Incorporate Cedar Wood
Cedar acts as an excellent spider repellent. Incorporate as much cedar into your house as possible. Fill your closet with cedar hangers or keep your clothes in a cedar chest. Place cedar blocks inside dressers, drawers, and other small spaces where spiders might dwell.
Make a DIY Cleaning Spray
To prevent spiders from making webs behind bookshelves, large furniture, closets, and more, Block says to “use a spray made of half a cup of water, half a cup of vinegar, two tablespoons of liquid dish soap, and 20 drops of thyme oil. The scented mixture has been used to prevent them from attaching their silk to sprayed surfaces.”
Repel Spiders with Dish Soap
Another natural spider repellent you can make from household supplies is a mixture of water and liquid dish soap. Dish soap disturbs the egg cycle of spiders, and the insects strongly dislike citrus scents—lemon, lime, or orange-scented soap will do the trick.
Turn Up the Music
By far the most fun of all the options is Block’s recommendation to add music to your cleaning routine. Sounds help ward off spiders. Block says that “spiders don’t have good eyesight, so they count on vibrations to detect their meals. The vibration from music will interfere with spiders’ ability to pick the perfect time to feast, and it will make them move to a quieter area elsewhere.”
