You can keep spiders away most effectively by cutting off their access and removing the things that draw them inside. Seal entry points, reduce insects, and keep your home clean and dry.
Most home spiders look for food, shelter, or both. Target those needs with your spider control plan.
A few small changes can make your home far less inviting to web-builders and hunters.
The Most Effective Strategy
Combine exclusion with cleanup for the best spider deterrent. Spiders enter through tiny openings, then stay where insects, dust, moisture, and clutter give them cover.
Seal Cracks, Gaps, And Door Sweeps
Check window frames, baseboards, utility lines, vents, and door edges for gaps. Add caulk, weatherstripping, and door sweeps so spiders have fewer ways in.
Cut Down Insects, Moisture, And Clutter
Spiders often follow their prey, so fewer bugs mean fewer spiders. Reduce standing water, fix leaks, dust regularly, and clear clutter in storage spaces.
Open doors and windows, excess moisture, and clutter all make homes more appealing.
Focus On Basements, Garages, Attics, And Window Areas
These quiet spots often get missed during cleaning. Vacuum webs, move stored items off the floor, and keep window screens in good shape.
Natural Repellents That Make Sense For Most Homes
Natural spider repellent options can help you protect high-traffic areas without harsh chemicals. Use them as a support step, not as your only plan.
Peppermint Oil And Peppermint Essential Oil Sprays
Many homeowners use peppermint oil or peppermint essential oil in a spray bottle with water. Mist it along windowsills, baseboards, and door frames to discourage spiders, and reapply after cleaning.
Citronella, Eucalyptus Oil, And Cedar Oil Options
Citronella, eucalyptus oil, and cedar oil are also popular natural spider repellents. Use them in diluted sprays or diffusers near entry areas, and test first on small surfaces to avoid staining.
Citrus Peels, Hedge Apples, And Other Low-Toxicity Remedies
Some people also try citrus peels or hedge apples in problem spots. Results vary, so treat these as low-toxicity add-ons rather than a full solution.

Where Barrier Treatments Help Most
Barrier treatments work best where spiders travel, hide, or enter. Apply them along edges, foundations, and outdoor paths.
Using Diatomaceous Earth Along Baseboards And Foundations
Diatomaceous earth can help in dry indoor or outdoor edge areas where spiders cross. Apply a thin line along baseboards or near foundation cracks, and keep it dry for best results.
When To Choose Food-Grade Diatomaceous Earth
If you use it inside, choose food-grade diatomaceous earth and follow the label closely. Keep it away from children and pets, and avoid creating dust clouds during application.
Applying Repellents Outdoors Around Patios, Mulch, And Entry Zones
Treat patios, door thresholds, and mulch edges for outdoor spider control. Cedar mulch may help reduce spider-friendly hiding spots near the home, especially when paired with tidy landscaping and fewer piles of debris.
When DIY Stops Working
If you still see spiders after sealing, cleaning, and using repellents, you may need stronger products or professional help. More webs, spiders in multiple rooms, or repeat sightings in hidden areas are good signs to step up.
Signs You Need Stronger Products Or Professional Help
You may need help if spiders keep returning after repeated vacuuming, or if you keep finding webs in the same corners. A pest pro can inspect for hidden entry points, nesting spots, and bug problems that keep spiders fed.
What To Do If You Keep Finding Egg Sacs Or Riskier Species
If you keep finding egg sacs, do not just crush them and walk away.
Carefully vacuum them, seal the bag, and clean the area right away.
If you see a black widow or another risky species, treat the area with extra caution.
