Mix 2 cups of warm water, 1/2 cup of white vinegar, 1 teaspoon of dish soap, and 15–20 drops of peppermint or lemon essential oil in a spray bottle. Spray this mixture directly on spiders to kill them, or along baseboards, windows, and entry points to deter them from returning.
The most effective homemade spider killer is a spray made of white vinegar, dish soap, and peppermint essential oil. The acetic acid in vinegar acts as a contact killer and burns spiders, while the strong scent of peppermint actively deters them from returning.
To get rid of spiders permanently, you must eliminate their food source (other insects) and remove their hiding spots. Combine rigorous decluttering with perimeter chemical treatments, sealing exterior cracks, and natural deterrents to make your home a hostile environment for arachnids.
Other methods for getting rid of spiders and keeping them out of your home include: Physical methods: Wong says the most surefire way to kill a spider instantly is to squish it with a shoe, swatter, or rolled up newspaper. “If you're afraid to get close, then vacuuming it up is a good option," he says.
Yes, a mixture of Dawn dish soap and water effectively kills spiders on contact.
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.
Windex kills spiders primarily because it acts as a solvent. Its active ingredients—specifically ammonia and surfactants (soaps)—work in three ways:
Spiders absolutely hate the scent of peppermint, citrus (lemon/orange), eucalyptus, and white vinegar. Because spiders "smell" and taste with sensory organs on their legs, these strong odors overwhelm their systems, confusing them and deterring them from building webs in your space.
Squishing Can Create More Problems
Unlike some insects, squishing spiders can sometimes: Spread eggs if it's a female carrying young. Leave behind messes or stains. Prevent proper identification.
Vinegar is a useful short-term natural deterrent, but it is not a permanent solution for an infestation. The strong smell and acetic acid will temporarily repel spiders and can kill them on direct contact, but it won't resolve the root cause of the problem.
To get rid of spiders permanently, you must eliminate their food source (other insects) and remove their hiding spots. Start by decluttering, vacuuming up webs and egg sacs, and sealing entry points with caulk. Follow up with targeted insecticide sprays and sticky traps around your home's perimeter.
To quickly kill spiders on contact, use targeted aerosol sprays like Raid Max Spider & Scorpion Killer or Black Flag Spider & Scorpion Killer. For a natural, kid- and pet-friendly alternative, you can mix a DIY spray of equal parts white vinegar and water with a few drops of peppermint or citrus essential oil.
Yes, it is perfectly safe to sleep in your bed, as spiders are incredibly shy and naturally avoid humans. The vibrations from your breathing and movements act as a natural deterrent, meaning a spider has no biological incentive to crawl on you while you are asleep.
3. use natural repellents
Yes, spiders do lay eggs in houses. Female spiders are drawn indoors seeking shelter, warmth, and abundant insect prey. They deposit their eggs into carefully constructed, silk-wrapped sacs that protect the developing offspring from predators and harsh environmental conditions.
Spiders are eaten by a wide variety of predators across the animal kingdom. Their main natural enemies include insectivorous birds, parasitic wasps (like the tarantula hawk), and other arachnids like scorpions. Amphibians, reptiles, and even other spiders also regularly prey on them.
Occasionally, a spider could get out of a vacuum. If it doesn't die from the initial trauma, a spider can escape the vacuum – but only if there are gaps big enough for them to get through and a surface they can climb.
The Bible does not explicitly command how to treat spiders, but it references them to teach both positive and negative spiritual lessons:
Is It Safe to Sleep With a Spider in the Room? It's not ideal, but yes—most spiders in our area are completely harmless. They'd much rather avoid you than bite you. In fact, even our venomous species usually only bite if they feel threatened.
To keep spiders away permanently, you must remove what attracts them: food and shelter. Combine deep cleaning to eliminate current hiding spots with sealing to block entry points, then use natural deterrents to discourage them from returning.
To coax a spider out of hiding, appeal to its hunting instincts or need for security. Use a vibrating object—like the handle of a battery-powered sonic toothbrush—against the wall or edge of its web to mimic trapped prey. Alternatively, place a few moist cotton balls or a small drop of water in a corner, as spiders frequently emerge to find hydration.
Dryer sheets can temporarily deter spiders and certain other bugs due to the strong synthetic fragrances they contain (such as linalool). However, experts state that there is no formal scientific evidence proving they are an effective or long-term spider repellent.
Killing a spider eliminates a built-in, chemical-free pest control system. Spiders are voracious generalist predators that eat hundreds of nuisance insects—including disease-carrying mosquitoes and flies. Rather than smushing them, use the cup-and-paper method to safely relocate them outside.
Other bugs tend to gravitate toward bright colors, like yellow, white, or orange. So while green attracts spiders, it repels their food sources. The color that spiders tend to hate is light blue. People don't just paint their porches light blue for the aesthetic.
The fastest and most surefire way to kill a spider immediately is with a direct physical strike (like a shoe or fly swatter) or by vacuuming it up. If you don't want to get close, aerosol spider killers, freezing aerosols, or household glass cleaners are the best instant-action alternatives.
