- Vinegar may kill spiders if they come into direct contact with them, but even if you don't spray the spider directly, it can help ward them off.
- Do not apply the spray to any varnished surfaces, as the vinegar may damage them.

Consider the benefits of spiders before you kill them. Certified pest management professional Chris Parker says: "Spiders are really beneficial around your home because they eat insects, so if you can stand to leave them alone, you should. If you can't deal with them in your house, though, you can place sticky traps under your cabinets and in corners to catch and kill them."

Apply essential oils like peppermint, tea tree, and cinnamon. These essential oils are a great natural way to deter spiders from hanging out in your home. Put 15-20 drops of essential oil in a spray bottle with 3 to 5 cups (710 to 1,180 ml) of water and spray your home once a day for a natural spider repellent.^{[2]

- Swap out different essential oils in the spray so the spiders do not get used to the scent of 1 particular oil.

Rub citrus peels on the floorboards and window sills in your home. Lemon and orange peels are a natural deterrent for spiders. Rub floorboards and window sills with the peels once a day so the smell lingers. You can also have a bowl of citrus fruits in your kitchen to keep spiders out of this area.
- Be aware that this could strip the paint off of your windowsill, so if you do try this, test it in an inconspicuous area first.
- You could also try placing citrus peels near your window sills and doorways to discourage spiders.
Horse chestnuts have a smell and texture that deters spiders. You can buy horse chestnuts at your local natural food store or online. They tend to last a long time and require no upkeep. Spread 4-5 horse chestnuts in each room, especially near windows, to keep spiders away.^{[3]

EXPERT TIP

Keeping the Inside of Your Home Clean

1
Do a weekly clean of your home to remove dust, dirt, and debris. Keeping your house clean will ensure there are no pieces of food on your floors that can attract spiders. Dust and dirt in the corners of rooms can also serve as a great hiding spot for spiders, so be sure to sweep or vacuum these areas regularly. Clean window sills and frames once a week, or daily, to prevent spider webs from forming.^{[4]

- You can also apply a natural vinegar or essential oil spray as part of your weekly clean to keep spiders away.
2
Check indoor plants for spiders. Spiders can hide in the leaves of indoor plants and spin webs in the plants. Make sure you check indoor plants every few days for spiders and remove them if you find any. You can also spray a natural pest repellent on the plant, such as white vinegar or essential oil spray.
- Another option is to make a spray out of 1 to 2 teaspoons (4.9 to 9.9 ml) diatomaceous earth powder and 2 to 4 cups (470 to 950 ml) water and apply it to your plants to keep spiders away.
- While most plants can tolerate being sprayed with vinegar, you may want to spray a small area first just to make sure yours won't be affected.
- Try spraying the area about once a week until you don't see spiders anymore.
If you notice spider webs or cobwebs on your rafters, corners, or window frames, use a cloth to wipe them away. This will prevent new spiders from moving into the webs.
4
Keep windows and doors to the outside closed. Prevent spiders from wandering inside your home by keeping windows and doors that open to the outside shut as much as possible. Tell others in your household to try not to leave windows or doors open.
- Installing screens on your doors and windows can help keep pests out while still allowing you to enjoy the fresh air.
5
Consider getting a cat to keep spiders away. Cats will hunt and eat spiders, and serve as a good deterrent to prevent spiders from coming inside. If you are not allergic to cats and are looking to get a pet, a feline friend can be a good way to have companionship, and keep spiders away.^{[5]

Keep outdoor plants away from the sides of your home. Spiders tend to burrow in the leaves and folds of plants. Try to arrange outdoor plants so they are at least 1 ft (0.30 m) away from the sides of your home. You can also spread diatomaceous earth, a white powder made of fossilized remains of algae, around plants or spray it on plants to kill spiders.^{[7]

- Avoid planting plants that will try to grow on the sides of your home, such as ivy or tall shrubs.
EXPERT TIP

"You can put diatomaceous earth anywhere you don't want creatures with exoskeletons, including your crawlspace and window sills."

Fill any gaps or cracks on the outside of your home. Inspect the exterior of your home to ensure you do not have any cracks in the foundation or gaps forming in your roof or under your doors. Fix any gaps, cracks, or holes by filling them with cement or filler.^{[8]

Spiders and small creatures are most likely to flee into your home immediately after a strong rain. Remember to keep windows closed for at least one day after wet weather to prevent them from nesting in your space.
