While both can help deter spiders, understanding how each type works can enhance your pest control efforts. White vinegar, with its higher acetic acid content, is particularly effective in killing spiders.
Combine 1 cup of water with 1 cup of white vinegar, and add 1 tablespoon of dish soap. Fill a small spray bottle with this mixture and apply directly to spiders and locations they frequent (cobwebs, cracks, wall corners, etc.
Yes, bleach can kill spiders. The active ingredients in bleach, primarily sodium hypochlorite, are toxic to many living organisms, including spiders. However, using bleach as a method to kill spiders is not the most effective or humane approach.
Here are some of them: Vinegar: A solution of equal parts vinegar and water can be sprayed directly on spiders to kill them. The strong smell also helps deter them. Dish Soap: Mixing dish soap with water in a spray bottle can suffocate spiders upon contact. Use about 2 tablespoons of soap per cup of water.
If you're determined to kill house spiders, use a spray of one-half cup water, one-half cup vinegar. The vinegar burns the spider and it should die soon after exposure.
In addition to peppermint, which was mentioned earlier, you can try using essential oils like lavender, eucalyptus, or citrus, as spiders tend to dislike these scents. You can create a homemade spider-repellent spray by mixing a few drops of these essential oils with water and applying it to spider-prone areas.
Pest control companies use insecticides containing pyrethrins, permethrin, and bifenthrin to target spiders and spider mites. These chemicals disrupt the spider's nervous system, causing paralysis or death. Additionally, physical barriers such as sticky traps may also be used to prevent spiders from entering buildings.
Vinegar: Mix equal parts white vinegar and water in a spray bottle and spray it directly onto any spiders you see. Vinegar contains acetic acid which burns the spider upon contact.
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.
White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.
Easy Ways to Kill Spiders
Spray a spider with enough Windex and it will die fairly quickly.
Salt is poisonous to spiders. You can create a saline solution using about ⅛ cup of salt mixed with a gallon of warm water. Pour it into a spray bottle and you have a natural spider-killing spray.
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.
Using a vacuum or broom to remove the spiders, webs and egg cases, and making sure the giant house spider's food sources are kept to a minimum and harborage sites are removed and cleaned up are also important prevention measures.
'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).
Dilute vinegar with water in a spray bottle in equal amounts and then spray in areas where spiders had previously been active. The acetic acid in the vinegar is harmful to spiders, but the strong odor of the vinegar alone will be enough to keep spiders away.
Hand sanitizer can be used in place of alcohol when mailing to preserve soft bodied arthropods such as aphids, spiders, insect larvae, (including caterpillars), and termites.
Powerwash contains several strong solvents, chelants, and high-alkaline ingredients that help it cling and decimate dirt—it's absolutely not regular Dawn dish soap in a pump spray bottle (as internet rumor has it). When I need to rid my dishes of stubborn stuck-on food, I'll just give 'em a soak.
Spraying an insecticide is one of the best methods to kill spiders from a distance. Spray the spider with a 1:1 mixture of white vinegar and water. Mix 1 cup (240 mL) of water and 1 cup (240 mL) of white vinegar in a spray bottle.
Baking soda is not only helpful for deodorizing but it can also help deter spiders. Sprinkle baking soda on potential entry points like doorways and windowsills. Keep in mind you may want to re-apply the baking soda once or twice a week.

Diatomaceous earth is a powder product homeowners often used to kill pests. While the name alone makes it sound like a fancy pest control or gardening resource, this substance is essentially just fine particles of fossilized single-celled organisms in the form of a fine white or off-white powder.
Many amphibians, reptiles, and fish eat both insects and spiders. Some hunt spiders, while others wait near their nesting places to ambush them. Snakes and lizards like geckos, chameleons, and anoles also help keep the spider population in check.
