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 like lemon, lime, or orange. Pour the mixture into a spray bottle and use it whenever you see a spider.
Lavender, mint, eucalyptus, and citronella are all plants with strong smells that spiders don't like. If you can grow these outside of your home near to entrances and windows, do so.
Salt is a natural type of spider poison, so it makes an effective pest control aide. Dissolve an ounce of salt (1/8 cup) in a gallon of warm water, and pour the saline mixture into a spray bottle. Spray the salty solution directly onto a spider to kill it. Saltwater is also effective at killing spider nests.
Spiders hate peppermint and citrus! Mix about 10-15 drops of peppermint essential oil OR a citrus essential oil (orange essential oil, lemon essential oil, or lime essential oil) to every 2 cups of water. You can also add a few drops of dishwashing soap or Castile soap for a little extra power.
You can spray peppermint oil or eucalyptus oil around every entrance and every area a spider may enter. Spiders do not like the smell of either and will avoid the smell. You could also buy spider repellant plants: Citronella Lavender Eucalyptus Mint.
Seal up your home to keep spiders from entering through cracks and crevices. Cover vents with fine mesh insect screens. Apply caulk around wires, cables, faucets and electrical components that run to the outside. Replace or fix torn window screens and caulk up gaps around windows.
Food Scents: Leftover crumbs, rotting food, and fruit attract insects, making your home a hunting ground for spiders. Light Floral or Fruity Scents: Some studies suggest that certain insects are drawn to sweet-smelling fragrances, which can lead spiders to follow.
White Vinegar – Since white vinegar has a high acid content, this is perfect to use against spiders. Place an equal amount of white vinegar and water in a spray bottle and use as needed. Spray directly onto spiders, their cobwebs, and areas that you've seen spiders in the past.
Fill a spray bottle with distilled white vinegar. Identify areas where spiders are commonly found, such as corners, crevices, and entry points. Spray a generous amount of vinegar directly onto these areas. Repeat this process daily until the spider activity subsides.
Fun fact: spiders aren't a big fan of strong smells. Spritz fresh-smelling essential oils like peppermint, tea-tree, eucalyptus, citrus and lavender around your home (especially entrances like doors and windows) to deter critters from entering and freshen up your rooms at the same time.
Easy Ways to Kill Spiders
Spray a spider with enough Windex and it will die fairly quickly.
'WD-40 is not an effective way to kill spiders and it will not repel or keep them away either. It is a lubricant and solvent, not a pesticide. The WD-40 may coat the spider's exoskeleton, making it difficult for the spider to move or breathe (and with enough could kill them by drowning/suffocation).
It turns out that soap and alcohol—the two main ingredients in Dawn Powerwash—are both great at killing insects. The soap clogs up insects' breathing tubes, essentially drowning them. Alcohol dries them out as well.
Some people believe that placing dryer sheets in corners or near windows can repel spiders. Again, while the scent might discourage spiders from settling in those areas, it won't solve the problem entirely. Spiders are attracted to homes with abundant food sources, such as other insects.
These eight-legged creatures hate the smell of citrus fruits such as lemons and oranges. They also don't like peppermint oils, tea tree oils, eucalyptus, and vinegar. Using any of these around your home will keep spiders away.
Spray the spider directly with an over-the-counter insecticide. “You can use over-the-counter [products] like Raid” to kill spiders instantly, instructs pest control professional Hussam Bin Break. There many options for commercial insecticides that are specifically designed to immediately kill spiders on contact.
Vinegar, primarily due to its acetic acid content, is more of a repellent than a killer. While it can kill some spiders on direct contact by causing dehydration, its primary use is to deter spiders from entering an area.
The best time of year to spray for spiders is in the warmer months of the year, especially Spring and early Summer. This isn't because you actually get better value, but because you see the effects of the spider spray more easily. In Spring, there's a lot of moving going on in the spider and insect world.
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.

Use Essential Oils: Spiders don't like the smell of certain essential oils, such as peppermint, eucalyptus, and tea tree oil. You can use these oils in a diffuser or spray them around your bedroom to keep spiders at bay.
Spiders are attracted to various factors in their search for shelter, food, and mating opportunities. Some common factors that attract spiders include the presence of insects or other prey, warm and dark spaces, and moisture.
Spiders really don't like strong scents such as citrus, peppermint, tea-tree, lavender, rose or cinnamon. Add 15 to 20 drops of your chosen essential oil or a couple of capfuls of Zoflora fragrance to a spray bottle filled with water, and spritz around the house.
