Spiders often find their way into homes for food, warmth, and shelter. They are attracted to insects, which are their primary food source. Thus, a house with plenty of insects will also likely attract spiders.

Common entry points for spiders include cracks in the walls, gaps around doors and windows, and vents. You can take proactive measures to keep them out by understanding their behavior and entry points.

Why Use Natural Spider Repellents?

Conventional chemical repellents can pose health risks, especially to children and pets. Exposure to these chemicals may lead to respiratory problems, skin irritation, and other health problems. On the other hand, natural spider repellents are safe to use around your home.

Environmentally, natural repellents are a better choice. Chemical repellents can harm beneficial insects and plants, disrupt ecosystems, and contaminate water sources. Natural options are eco-friendly and sustainable.

Despite common misconceptions, natural repellents can be as effective as chemicals, provided you use them consistently.

Top 8 natural spider repellents.

Many people share a common concern about keeping spiders out of their homes. Spiders, though mostly harmless, can still give anyone the chills.

According to scientific research by National Geographic on spiders, ‘he vast majority of spiders are harmless and serve a critical purpose: controlling insect populations that could otherwise devastate crops. Without spiders to eat pests harmful to agriculture, it’s thought that our food supply would be put at risk.’

Essential Oils

Essential oils are potent and versatile. They work by overwhelming a spider’s senses, making your home less inviting.

Popular Essential Oils for Repelling Spiders

Some of the most effective essential oils for repelling spiders are Peppermint, lavender, and tea tree oil. These oils have strong scents that spiders find unbearable.

Application Methods

Mix few drops with water in a spray bottle to use essential oils. Spray this mixture around windows, doors, and other entry points. You can also use a diffuser to spread the spray scent throughout your home.


Vinegar is a common household item with acidic properties that repel spiders.

Properties of Vinegar

The pungent smell and acidity of vinegar disrupt spiders’ sensory organs, stopping them from entering treated areas.

How to Use

Mix equal parts of the vinegar and water in a spray bottle. Then spray this solution around door frames, windowsills, and other areas where spiders are likely to enter. Reapply the solution every few days for the best results.


Citrus fruits, like oranges and lemons are refreshing and practical at repelling spiders.

Citrus Fruits

Spiders dislike the smell of citrus. The citrus’s zesty scent acts as a natural deterrent.

Usage Tips

Place citrus peels where spiders are commonly found, such as on windowsills, corners, and under furniture. Citrus spray can also be made by boiling peels in water and using the cooled liquid as a repellent.

Diatomaceous earth is a fine powder made from fossilized algae. It’s a natural and effective way to keep spiders at bay.

What is Diatomaceous Earth?

This natural substance is safe for humans and pets but lethal for spiders. It works by damaging their exoskeletons, leading to dehydration and death.

How It Works

When spiders come into contact with diatomaceous earth, the sharp particles pierce their exoskeletons, causing them to dry out.


Sprinkle diatomaceous earth in areas where spiders are likely to enter, such as around windows, doors, and baseboards. Reapply after cleaning or if the powder gets wet.


Cedar has been used for centuries as a natural insect repellent. Its strong scent is particularly effective against spiders.

Cedar’s Repellent Properties

The aromatic oils in cedar wood repel spiders and other pests. They work by overwhelming the spiders’ sense of smell.

Uses in the Home

Place cedar blocks, shavings, or essential oil near windows, doors, closets, and other entry points. Cedar furniture and chests can also help keep spiders away.


Mint is another excellent natural spider repellent. Both mint plants and mint oil can be used to repel spiders.

Mint Plants and Oils

Mint has a strong, refreshing scent that spiders find unappealing. Growing mint plants around your home can act as a natural repellent.

Application Methods

Plant mint around the perimeter of your home and in pots indoors. Additionally, you can use mint essential oil mixed with water as a spray, similar to other essential oils.

Keep a Clean House

A clean home is less attractive to spiders. Regular cleaning removes the webs and food sources that spiders rely on.

Importance of Cleanliness

Maintaining cleanliness helps reduce the chances of having insects that attract spiders.

Practical Cleaning Tips

Focus on cleaning corners, under furniture, and behind appliances where spiders tend to hide. Regularly vacuuming and dusting these areas can make a significant difference.


Chestnuts are an unexpected but effective natural spider repellent.

The Science Behind It

While it’s unclear why chestnuts repel spiders, some believe it has to do with a natural compound they contain.

How to Use

Place chestnuts around your home, such as windowsills, doorways, and corners. Replace them every few months to maintain their effectiveness.
