How to Get Rid of Spiders: Effective Indoor & Outdoor Strategies
Natural oils and smart sealing create lasting peace of mind throughout living spaces.
Spiders are a common household pest, often finding their way inside in search of food or shelter. While they play a beneficial role outdoors by controlling other insects, their presence indoors can be unsettling for many. This comprehensive guide offers proven strategies—including natural repellents, cleaning habits, sealing techniques, and expert advice—to help you eliminate and prevent spiders throughout your home and yard.
Why You Might Want to Get Rid of Spiders
Spiders pose little direct harm to humans, but their webs, eggs, and presence can be alarming. While many are harmless, a few species like black widows or brown recluses require extra caution. Most commonly, people want to rid their homes of spiders for peace of mind and cleanliness.
General Prevention Tips for Keeping Spiders Away
- Keep your home clean and free from clutter: Spiders are attracted to environments where they can hide. Maintaining a tidy space with minimal clutter reduces their hiding spots and makes your home less inviting to them.
Regular vacuuming removes spider webs, eggs, and insects spiders use as food sources. - Seal gaps and cracks: Inspect your home, especially around windows, doors, and foundations, for small openings. Seal these with caulk, weatherstripping, or filler to block entry points.
- Remove spider webs on sight: Actively check corners, ceiling edges, and seldom-used rooms. Remove webs promptly to discourage spiders from settling.
- Be careful with what you bring inside: Boxes, firewood, and outdoor items can harbor spiders. Check and shake out items before bringing them indoors to minimize accidental introductions.
Natural Spider Repellents to Try at Home
Natural repellents can be both effective and safer for families and pets. Many common household substances are disliked by spiders, making them useful tools in your pest-control arsenal.
- Peppermint oil: Mix 20 drops with water in a spray bottle. Apply to baseboards, corners, and window sills. Cotton balls soaked in oil can be placed in crevices.
- Eucalyptus oil: Works similarly to peppermint; targeted sprays discourage spiders from nesting.
- Vinegar: Mix equal parts vinegar and water. The acetic acid burns spiders on contact; spray directly onto webs or suspected nesting spots.
- Diatomaceous earth (DE): Sprinkle in thin layers behind cabinets, in corners, and along exterior foundations. DE lacerates the exoskeleton, dehydrating spiders. Clean residue promptly and avoid food prep areas.
- Lemon juice and baking soda: These create acidic or drying conditions that spiders avoid. Lightly mist or dust along common entry points.
- Cedar wood: The natural oils in cedar are repellent to spiders. Use cedar hangers or furniture, or place chips in dark closet corners.
Natural Repellent Recipes
| Repellent | Preparation | Application |
|---|---|---|
| Peppermint Oil Spray | 20 drops peppermint oil + 32 oz water | Spray on surfaces, cotton balls in cracks |
| Vinegar Solution | 1 part white vinegar + 1 part water | Spray directly onto webs and spiders |
| Diatomaceous Earth | Sprinkle dry powder | In hard-to-reach areas, exterior perimeters |
| Cedar Wood | Cedar hangers, chips | Closets, drawers, furniture |
Outdoor Prevention: Keeping Spiders from Getting In
- Seal up your home: Use caulk around wires, cables, outdoor faucets, and window edges. Ensure vents are covered with fine mesh insect screens.
- Maintain your garden and landscaping: Prune shrubs, trees, and ivy back from your home’s walls. Remove vegetation within eight feet to limit spider access and reduce insect prey.
- Plant eucalyptus: Eucalyptus is a natural spider deterrent. As an evergreen, it also reduces leaf litter where spiders might hide.
- Switch outdoor lights: Use yellow sodium vapor bulbs or simply turn off non-essential outdoor lights, as bright lights attract insects that become spider prey.
Lethal Methods: When Natural Remedies Aren’t Enough
For more persistent infestations, you may need to use stronger tactics. Always exercise caution and follow instructions when using chemicals.
- Spider traps and glue boards: Place non-toxic sticky boards in corners, behind furniture, and along walls. Monitor regularly and discard once full.
- Spider sprays: Most commercial formulas use pyrethroids (derived from chrysanthemum flowers), which kill on contact but leave residues. Spray baseboards, under furniture, and in hidden spaces. Allow surfaces to dry before children or pets return.
- Professional pest control: In cases of severe infestations or presence of dangerous species (black widows, brown recluses), consider hiring expert services for safe and thorough removal.
Step-by-Step Guide to Removing Spiders
- Inspect your home for webs, eggs, and hiding spiders. Look behind boxes, inside closets, and around entry points.
- Remove spider webs with a vacuum cleaner, making sure to empty the vacuum promptly to avoid eggs hatching inside.
- Seal entry points with caulk, weatherstripping, or filler. Focus on windows, doors, vents, and baseboards.
- Apply natural repellents (peppermint oil spray, vinegar, diatomaceous earth) in problem areas and possible entry points.
- Place traps in corners, near walls, and in areas where spider activity is high.
- Address outdoor risks by pruning vegetation and switching outdoor lighting, as well as planting deterrent plants like eucalyptus.

Maintaining a Spider-Free Home
Consistent effort is key to keeping spiders at bay. Incorporate these practices into your daily and seasonal routines:
- Regularly clean and vacuum all rooms, corners, and seldom-used areas.
- Keep food stored in sealed containers to reduce the presence of other pests like ants and roaches, which attract spiders.
- Minimize clutter, especially piles of magazines, laundry, or cardboard boxes where spiders may hide.
- Monitor and refresh repellents as needed, especially natural substances that require reapplication.
- Check and repair seals, screens, and weatherstripping on doors and windows every season.
Safety Tips for Spider Control
- Ensure all sprays and powders are kept away from food preparation areas.
- Read and follow product labels strictly, especially if pets or small children are present.
- Wear gloves and long sleeves when cleaning behind furniture, moving firewood, or reaching into seldom-used corners.
- Clean up diatomaceous earth and other fines promptly to avoid respiratory irritation.
Understanding Spider Behavior
Spiders enter homes primarily in search of prey. If your home is free of other insects and hiding spots, it becomes a less attractive environment. Most species pose no direct threat, but understanding their habits helps you tailor your control efforts effectively.
- Common indoor species: House spiders, cellar spiders, and jumping spiders are typically harmless but can multiply quickly in undisturbed spaces.
- Dangerous species: Black widows and brown recluse spiders require immediate professional intervention due to their medical risks.
- Webbing locations: Spiders prefer dark, quiet, and undisturbed areas for web-building, such as basements, attics, crawl spaces, and garages.
Frequently Asked Questions (FAQs)
Q: Are any household spiders dangerous?
A: Most household spiders are harmless. However, if you suspect the presence of black widows or brown recluse spiders—identified by their markings and bite symptoms—seek professional assistance.
Q: Do natural repellents really work?
A: Natural repellents like peppermint oil, vinegar, and diatomaceous earth are effective when applied correctly and regularly. They work better as preventative measures than solutions for large infestations.
Q: Will spiders come back after removal?
A: Without consistent cleaning, sealing, and repellents, spiders can return. Long-term prevention rests on removing food sources and maintaining a tidy, sealed home.
Q: Is it better to kill spiders or remove them?
A: Removing spiders safely—using catchers or relocating them outside—is preferable, especially for beneficial species. Use lethal methods only if necessary for safety or persistent infestations.
Q: How often should I apply natural repellents?
A: Natural sprays and substances should be refreshed every few weeks or after cleaning, as they fade and dissipate over time.
