Spiders are fascinating creatures, but let’s be honest—most of us would rather not share our homes with them. Whether it’s the sight of a web in the corner of your ceiling or the sudden appearance of a spider scuttling across the floor, these eight-legged visitors can make even the bravest among us uneasy. If you’ve ever wondered what spiders hate the most and how to use that knowledge to keep them out of your home, you’re in the right place.
Understanding Spiders and Why They Enter Homes
Before we dive into how to keep spiders away, it’s essential to understand why they enter our homes in the first place. Knowing their motivations can help you take targeted steps to prevent them from invading your space.
Why Do Spiders Come Indoors?
Spiders don’t enter your home to scare you—they’re simply looking for the essentials: food, shelter, and warmth. Here’s a breakdown of their motivations:
- Food: Spiders feed on insects, so if your home has a bug problem, it’s essentially a buffet for them.
- Shelter: Spiders seek out quiet, undisturbed areas to build their webs and lay eggs.
- Warmth: As temperatures drop, spiders often move indoors to escape the cold.
Common Spider Species Found in Homes
Not all spiders are the same. Some of the most common species you might encounter indoors include:
- House spiders: Small and harmless, these spiders are the most frequent visitors.
- Cellar spiders, also known as daddy long legs, prefer damp, dark spaces, such as basements.
- Wolf spiders: Larger and more intimidating, these spiders don’t spin webs but hunt their prey directly.
The Ecological Role of Spiders
While spiders can be unsettling, they play an essential role in controlling insect populations. However, this doesn’t mean you have to tolerate them in your home. By understanding what spiders hate the most, you can keep them out without harming them or disrupting their role in the ecosystem.
What Do Spiders Hate the Most? Natural Repellents Explained
Spiders are sensitive creatures with strong aversions to certain smells and substances. By using natural repellents, you can create an environment that spiders find uninviting. Let’s explore some of the most effective options.

Peppermint Oil: A Spider’s Worst Enemy
One of the most well-known spider repellents is peppermint oil. Spiders hate the strong, minty scent, which overwhelms their sensitive senses.
- How to Use It: Mix 10-15 drops of peppermint oil with water in a spray bottle. Spray this mixture around windows, doors, and other entry points.
- Pro Tip: Reapply the spray every few days for maximum effectiveness.
Vinegar and Citrus Scents
Spiders also dislike the smell of vinegar and citrus fruits like lemons, limes, and oranges.
- Vinegar Spray: Combine equal parts white vinegar and water in a spray bottle. Use it to clean surfaces and spray corners where spiders might hide.
- Citrus Peels: Rub lemon or orange peels along windowsills and door frames to naturally deter spiders.
Herbs and Plants That Repel Spiders
Certain plants and herbs are natural spider repellents. Consider incorporating these into your home or garden:
Plant/HerbWhy It WorksHow to Use It
Mint’s Strong scent overwhelms spiders Plant near windows or use dried mint leaves indoors.
Lavender is Calming for humans and repellent for spiders Place sachets of dried lavender in closets.
Basil Natural insect repellent Keep potted basil plants in your kitchen
Eucalyptus Strong, medicinal scent Use eucalyptus oil or fresh leaves
Other Natural Repellents
- Tea Tree Oil: Similar to peppermint oil, tea tree oil can be mixed with water and sprayed around the house.
- Conkers (Horse Chestnuts): A traditional method involves placing conkers in corners, which is believed to repel spiders.
- Diatomaceous Earth: This natural powder dehydrates spiders and other pests. Sprinkle it in areas where spiders are likely to crawl.
Combining Repellents for Maximum Effect
For the best results, use a combination of these repellents. For example, you can spray peppermint oil in entryways, place lavender sachets in closets, and grow basil in your kitchen. This multi-pronged approach will make your home as uninviting as possible for spiders.
Practical Home-Proofing Strategies to Keep Spiders Out
While natural repellents are effective, they work best when combined with practical home-proofing strategies. Here’s how to make your home a fortress against spiders.

Seal Cracks and Gaps
Spiders can squeeze through even the tiniest openings. Inspect your home for cracks and gaps around windows, doors, and vents.
- What to Do: Use caulk to seal cracks and weatherstripping to close gaps around doors and windows.
- Pro Tip: Don’t forget to check less obvious entry points, like utility pipes and vents.
Regular Cleaning and Vacuuming
Spiders love undisturbed areas, so regular cleaning is key.
- Focus Areas: Pay special attention to corners, under furniture, and behind appliances.
- Vacuuming Tips: Use a vacuum with a hose attachment to remove webs, egg sacs, and any spiders you find.
Reduce Outdoor Lighting
Outdoor lights attract insects, which in turn attract spiders. To minimize this:
- Use yellow or sodium vapor bulbs, which are less attractive to insects.
- Turn off outdoor lights when not needed.
Declutter and Remove Hiding Places
Spiders thrive in cluttered environments. Decluttering both indoors and outdoors can significantly reduce their hiding spots.
- Indoors: Clear out piles of clothes, boxes, and other clutter.
- Outdoors: Remove woodpiles, leaves, and other debris near your home.
Maintain Your Yard and Garden
A tidy yard can prevent spiders from getting too close to your home.
- Trim bushes and trees that touch your house.
- Keep grass short and remove weeds.
Additional Tips and Lifestyle Changes to Prevent Spiders
Beyond repellents and home-proofing, small lifestyle changes can make a big difference in keeping spiders away.
Keep Windows and Doors Closed at Night
Spiders are nocturnal and more likely to enter your home at night. Make it a habit to close windows and doors after sunset.
Use Pets as Natural Spider Deterrents
Did you know that cats and dogs can help keep spiders at bay? Pets often chase and eat spiders, reducing their numbers in your home.
Routine HVAC and Duct Cleaning
Spiders can enter your home through vents and ducts. Regular cleaning of your HVAC system can prevent this.
Regular Web Removal
Consistently removing webs discourages spiders from settling in your home. Use a broom or vacuum to clear webs as soon as you spot them.
When to Call a Professional and Safety Considerations
Sometimes, DIY methods aren’t enough. Here’s when to consider professional help:
- Dangerous Spiders: If you spot venomous species like black widows or brown recluses, it’s best to call a pest control expert.
- Severe Infestations: If your home is overrun with spiders, professional exterminators can provide a more thorough solution.
Safety Tips
- Always wear gloves when handling spiders or cleaning webs.
- Follow instructions carefully when using natural repellents to avoid skin irritation or damage to surfaces.
