While most species are not dangerous, spiders can be a nuisance when they get inside your home. They spin webs everywhere, jump out at you when you're least expecting it, hide in your personal belongings, and leave spider bites that can be painful. Moreover, the presence of spiders can indicate another pest problem since spiders need a food source to survive. Another disturbing fact is their population can increase over time if you let them be. 

How to kill spiders? Is there any way to repel these pests for good? Killing them is the surest way. If you are determined to wipe out spiders in your home, consider these practical ways to get rid of them permanently. 

How To Kill Spiders Instantly

Use An Insecticide Spray

To deter spiders, use a high-performance insecticide spray and regularly spray it on areas in your home that are spider-prone. A good quality aerosol spray can kill spiders in the house and prevent them from infesting. You may want to look for a purpose-built spray to keep your home safe and protected from crawling insects for up to180 days. Remember to spay on surfaces and around doorways and windows to keep spiders from crawling inside. 

Squish The Spider

Spiders around your houses are usually harmless. Common house spider species include the wolf spider, hobo spider, cellar spider, cobweb spider, orb weaver spider, and jumping spider, which can be easily killed with a tissue or object. However, getting rid of them in close proximity is not the best idea if they are squeamish or have a phobia. 

 If you aren't sure about the species of the spider, don't attempt to squish. Always make sure that the spider you are about to kill isn't a venomous spider. Black widow spider and brown recluse spider likes are dangerously aggressive and have a potent sting that causes allergic reactions and can be fatal. 

Vacuum the spiders up

Using a strong vacuum is an excellent idea to get of spiders, spider web, spider eggs, and any potential spider egg sac that the mother spider has left behind. Just remember to use the long hose to suck up the spider and let the vacuum run for some time to make sure the spider dies in the vacuum bag. Immediately dispose of the tightly sealed vacuum bag. If your vacuum is bagless, empty the dust canister and all the creepy crawlers you've collected afterward. Vacuuming is a safer way to kill spiders, especially if you deal with a dangerous spider or poisonous spider species.

Use a pest control or bug bomb.

One of the best ways to get rid of spiders and other household pests in your home is by using a pest control or bug bomb. This product helps cover a larger surface area and gives you the ability to do it yourself. The bomb works by releasing a fine mist that spreads into a room and kills seven types of pests, including spiders.

Natural Ways To Repel Spiders 

You don't need to use pesticides with hazardous chemicals that can hurt you, your family, and your pets to solve your spider problems or get rid of spiders. Thanks to these natural methods and ingredients: 

Essential Oils 

Essential oils such as rose, citronella, cinnamon, citrus, spearmint, eucalyptus, lavender, tea tree, and peppermint can repel spiders. According to experts, most essential oils have insecticidal properties through monoterpenoids. The content produces an aroma which spiders hate makes it a natural spider repellent. Just dilute your essential oil with water and place the mixture in a spray bottle. Apply the mixture in areas you have spotted spiders like cracks, crevices in your walls, doorways, and window sills. 

Aside from repelling spiders, these essential oils effectively eliminate mosquitoes, bed bugs, spider mites, and other insects. 

Since essentials are highly concentrated in nature, it's best to dilute your mixture and use protective gear like gloves and a face mask to avoid irritations from these essential oils.  

Ensure to open your windows after using the essential oil solution to prevent congesting your space with the aroma that could harm your children and pets. Alternatively, you can also soak cotton balls in essential oils and place them in different areas of your house where spiders are always seen. 

White Vinegar and Other Household Items 

White vinegar is a household product you can use to get rid of spiders. Its odor is effective in repelling spiders. White vinegar has acetic acid content which can kill spiders upon contact. To create a homemade, natural spider killer, mix one cup of white vinegar with two cups of warm water. Apply the mixture in areas where spiders hide their egg sac and nest once a day or every week. 

You can also use baking soda to repel spiders from your home as a safer alternative. 

Repel Spiders with Dryer sheets 

Dryer sheets also contain monoterpenoid through a floral-scented ingredient called linalool, which has a toxic effect on spiders, mosquitos, and other insects. 


Anecdotal evidence infers that horse chestnuts and walnuts are also effective in repelling spiders in your home. Just place them strategically on window sills or any corners of your house where you always see spiders. Unlike natural sprays, nuts can repel spiders for a long time without having to replace them regularly. 


Another natural ingredient that many claims can get rid of spiders is Cedarwood. You can use this by spreading cedarwood chips around your house or mixing cedarwood oil into spider spray. 

Citrus Peels 

You can use your leftover citrus peels, lemon peels, and orange peels to get rid of spiders in your home. As long as their smell is potent enough, you can put the peels in areas where spiders are active or rub them doorways, windowsills, shelves, and baseboards


Spreading tobacco leaves in areas with signs of spider activity is another natural ingredient that can repel spiders. Alternatively, you can mix with water and use it as a homemade repellent spray or mix with water and flour to make tobacco balls. 

Sticky Trap

Another non-toxic solution to lessen spider population in your property is a Homemade sticky trap. 

Just boil equal amounts of water and corn syrup. Mix it until you have a sticky paste. Apply and spread this paste onto a rectangular piece of cardboard or empty cereal box. Place the spider trap in areas with spider activity, like inside cabinets, baseboards of walls, or behind your furniture. 

Diatomaceous Earth

To deal with and get rid of spiders outside your house, using diatomaceous earth as a non-toxic ingredient is another natural way. Just spread thin lays of the powder on areas where spiders are lingering. Remember to wear protective gear when applying to avoid skin and lung irritation.

Pets and Other Insects

Pets are part of nature and can also help in spider control. Cats, for instance, won't be able to resist catching spiders. Taking care of a pet can dissuade spiders from coming around. As for your garden, ladybugs would feast on the insect pests that spiders prey on. And without these insects, the spiders will move somewhere else.
