Natural Ways to Keep Spiders Out of Your Home
Discover eco-friendly methods and science-backed tips to prevent and repel unwanted spiders naturally inside your home.
Spiders play a valuable role in controlling unwanted pests, but for many, they’re still unwelcome houseguests. If you’d prefer a spider-free living space without resorting to harsh chemicals, a wealth of natural solutions is at your disposal. This guide breaks down the best science-backed, eco-friendly strategies—ranging from essential oils and household remedies to practical cleaning habits and exclusion tactics—for keeping spiders at bay and reclaiming your home.
Why Keep Spiders Out—But Don’t Panic
While most household spiders are harmless and actively reduce populations of flies, mosquitoes, and other insects, their presence can be unsettling for many people. Fortunately, there are plenty of effective, non-toxic approaches to managing minor spider problems and creating a less hospitable environment for eight-legged intruders—all while being gentle on the planet and your pets.
What Natural Scents and Ingredients Repel Spiders?
Spiders are highly sensitive to certain strong fragrances and substances that humans often find pleasant. The following natural ingredients are frequently reported as effective spider deterrents:
- Peppermint: Spiders are repelled by minty aromas. Planting mint outside, using peppermint oil sprays indoors, or placing oil-soaked cotton balls in spider-prone spots can discourage spiders from settling.
- Essential Oils: Oils including cinnamon, tea tree, eucalyptus, lavender, and rose are known to interfere with a spider’s sense of smell. Dilute 10–20 drops into water and use as a spray for cracks, corners, and windowsills.
- Cedar: Cedar wood’s natural oils help keep spiders (and many other pests) away. Use cedar blocks, balls, planks, or hangers within closets, pantries, and bathrooms.
- Garlic: Crushed garlic cloves steeped in water may form a strong-smelling spray to apply to corners and baseboards.
- Vinegar: White vinegar diluted with water is a popular cleaner and repellent. The acetic acid is unpleasant to spiders when sprayed along entry points and hiding spots.
- Citrus: Spiders avoid strong citrus odors—try rubbing lemon or orange peels on window ledges or using lemon-scented cleaners.
- Chestnuts: There is anecdotal evidence that the scent from chestnuts repels spiders; simply set a few in strategic locations, such as on windowsills.
Most natural repellents work best when frequently reapplied, especially after cleaning or if ventilation is high.
14 Natural Spider Repellents and Prevention Strategies
1. Clean Every Corner and Declutter Regularly
Cleaning and decluttering are simple yet powerful spider deterrents. Vacuum regularly (especially in corners, behind furniture, and under beds) to remove webs, egg sacs, and their favored hiding places. Remove clutter such as stacks of newspapers, boxes, and unused items where spiders can shelter.
2. Remove Food Sources (Insect Management)
Spiders are attracted by the presence of other insects. Reducing other bug populations—by storing food securely, cleaning up crumbs, and fixing screen tears—will diminish spiders’ food supply and make your home less attractive to them.
3. Apply Peppermint Oil
- Mix 10–15 drops of pure peppermint oil with water in a spray bottle.
- Spray along windowsills, doorways, baseboards, and wherever spider activity is seen.
- Reapply every few days for continued effectiveness.
4. Place Whole Chestnuts in Problem Areas
Set uncracked chestnuts on window sills, along baseboards, and near potential entry points. Their scent is believed by many to ward off spiders—with no mess or residue left behind.
5. Incorporate Cedar Wood
- Install cedar closet liners or chests for clothing storage.
- Scatter cedar blocks or balls in drawers, cabinets, or beneath sinks.
6. Make a DIY Cleaning and Repelling Spray
A multipurpose cleaning solution can double as a spider deterrent:
- Combine equal parts water and white vinegar, 2 tablespoons of dish soap, and 20 drops of thyme or eucalyptus oil.
- Spray on surfaces where you’ve previously seen spiders or webs.

7. Use Dish Soap as a Mild Pesticide
A simple mix of water and mild dish soap disrupts egg cycles and deters spiders. Citrus-scented dish soaps provide added repelling power. Spray in areas where spiders are active for best results.
8. Vibrations and Music as Deterrents
Adding soft vibrations—such as playing music—during cleaning can disturb spiders’ ability to sense prey, encouraging them to leave.
9. Protect the Home’s Exterior
- Move firewood, stones, and brush piles away from exterior walls.
- Trim plants and shrubs so they do not touch exterior walls or windows.
- Repair torn window screens and seal gaps in vents or around doors.
10. Grow Eucalyptus and Aromatic Plants
Top aromatic plants for your garden include eucalyptus, lavender, mint, and citronella. Position these plants near windows, entries, or areas where spiders might enter.
11. White Vinegar as a Preventative Treatment
- Fill a spray bottle with a 50/50 mix of water and white vinegar.
- Apply to cracks, under sinks, and in dark corners to repel spiders.
12. Seal Cracks and Gaps in Exterior Walls
Use caulking or weatherstripping to seal cracks and gaps in siding, window frames, door thresholds, and foundations. This prevents easy spider entry and also improves energy efficiency.
13. Manage Recycling and Trash
Empty recycling bins and garbage regularly, especially containers that held sugary substances or food residue, which attract both bugs and spiders.
14. Use Citrus Peels and Lemon Cleaners
- Rub fresh lemon or orange peels along window sills, doors, and baseboards.
- Choose lemon-scented cleaners or consider citronella candles for lingering fragrance and added repellent benefits.

Natural Spider Control: Exclusion and Habitat Modification
- Seal all entry points: Spiders enter through minuscule gaps around doors, windows, and sidings. Seal these with caulk or weatherstripping for lasting protection.
- Yard maintenance: Keep landscaping neat and well-trimmed; move debris piles far from the foundation.
- Reduce lighting: Outdoor lights attract insects at night, which in turn attracts spiders. Use motion sensors or yellow bulbs to minimize this effect.
Benefits of Natural Spider Control Methods
- Environmentally friendly: Avoids harsh pesticides that can harm non-target wildlife and beneficial insects.
- Safe for kids and pets: Most natural methods use food-safe ingredients and are generally low in toxicity.
- Holistic: Works in harmony with the home’s ecosystem, supporting a balanced approach to pest management.
Verdict: Embrace Eco-Friendly, Integrated Pest Control
Maintaining a spider-free home does not require heavy chemicals or drastic measures. With consistent cleaning, strategic use of scent-based deterrents, and attention to exclusion and cleanliness, you can effectively minimize spider presence. For serious infestations or dangerous species like black widow or brown recluse spiders, consult professional pest management experts. However, for most households, these natural solutions are effective for prevention and peace of mind.
