Bleach is considered a pesticide and fungicide because it kills bacterial cells, which makes it an option for spider control in your house.
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 bleach can do double duty because it does kill spiders if used correctly. You start by mixing one part bleach with three parts water in a spray bottle. The mixture can be used directly on spiders when you see them and also in areas where they likely enter your home.
Even though white vinegar does have a strong smell, it's not what makes your spider problem go away. White vinegar contains acetic acid that actually harms spiders. When you make a diluted solution, it safely and successfully harms and kills spiders without putting your kids or pets in danger of chemical exposure.
Spiders directly exposed to a spider control spray will definitely die after a short period of time, ranging from just a few hours to a couple of weeks.
Even so, they certainly cannot suffer because they don't have emotions. If you heavily injure an insect, it will most likely die soon: either immediately because it will be unable to escape a predator, or slowly from infection or starvation.
So why do they work on insects but not on spiders? We look at how spiders could have evolved to resist insecticides because of their venom. Insecticides don't work on some spiders because their venom mimics the effects of the active chemicals.
Although windex technically can kill spiders, it's just not an effective and practical way to kill and get rid of spiders in your home. Windex is only effective in killing a spider when it's applied directly to the spider.
White Vinegar
Vinegar spray can serve as an organic pest control, specifically for spiders. While it is harmless to humans, it contains acetic acid which gives it a sour taste and odor which spiders are highly sensitive to. To use, mix equal portions of vinegar and water in a spray bottle.
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.
Windex is a popular household cleaner that is considered very safe for humans, and very dangerous for pests. If you see a pest inside of your home, spraying them with Windex often means instant death. Windex can be very effective for spiders, and for killing large numbers of ants.
Bleach is more than just a powerful cleanser; it is also a powerful pesticide. It can get rid of various pests, including drain flies and mosquitoes. If you're looking to kill bed bugs at home, here's what you need to know about using bleach to get rid of these pests once and for all.
It's easy to keep spiders away using natural products. 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.
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.
1) It takes nearly 1/2 of a full can of Lysol Disinfectant Spray to kill a spider that is hanging out on the door to your office. 2) Lysol has a spraying distance of about 2 feet, meaning that you'll have to get closer to said spider than you prefer due to your total arachnophobia.
Repel Spiders with Dish Soap
Another natural spider repellent you can make from household supplies is a mixture of water and liquid dish soap.
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.
Their own bigger relatives. If you have a paralyzing fear of spiders, here's a Halloween treat: Some spiders can be literally scared to death by their own eight-legged relatives.
Instead of these muscles, spiders use the blood pressure spike from their heartbeat to extend their legs out, as the graphic below from Jacob O'Neal for BBC Earth explains. And with no heartbeat when the spiders cease to exist, they curl up upon death.
