9 Tips for Spider-Proofing Your Home

How to Prevent Spiders

Spiders. Just the word is enough to make many people shudder. While they play an important role in controlling insect populations, having too many of them invading your home can be downright creepy. Luckily, there are ways to discourage these creepy crawlies from setting up residence in your house without using harmful chemicals. Of course, if infestation is already severe, hire professional pest control from Green Pest Control.

What Attracts Spiders to Your Home

Before getting into how to prevent spider infestations, it’s helpful to understand what draws them inside in the first place. Spiders are attracted to warm, dark places with plenty of insects to eat. Common entry points include cracks and gaps around windows, doors, attics, basements, and crawlspaces. These arachnids may also crawl inside if you leave doors or windows open. Once inside, they build webs in undisturbed corners and crevices. Keep these habits in mind as you work to spider-proof your home.

9 Ways to Keep Spiders at Bay

1. Keep Your House Clean

Spiders love dusty, dark areas filled with webs, even cobwebs made by other spiders. Regular cleaning deprives them of these ideal hangouts. Target nooks, ceilings, attics, basements, garages, sheds, and other infrequently cleaned areas.

You can also use the hose attachment to vacuum up webs and spiders in corners, along walls, and in hard-to-reach crevices. Check window and door frames where sticky webs like to accumulate. Empty the vacuum bag or canister outside after each use.

2. Seal Gaps and Cracks

Block secret passageways into your home. Caulk and seal openings around pipes, vents, and foundations. Pay special attention to favourite hiding places like the attic, basement, and garage.

These pests can fit through really tiny cracks and openings. Check very thoroughly and seal every little crack you find to block all the ways they could possibly get in. If you see a gap bigger than 1/16 of an inch, a spider could fit through it. Stuffing steel wool into holes temporarily can help until you have time to caulk it properly. Be very thorough to seal off all entry paths.

3. Limit Outdoor Lighting

Outdoor lights attract night-flying insects that spiders feast on. Limit lighting to reduce the buffet outside your home. Turn them off or switch to yellow bulbs, which are less attractive to insects. Cutting back lighting means fewer bugs and less food source available. This is also better for getting good sleep.

4. Try Natural Repellents

Natural ingredients like essential oils and spices make safe, eco-friendly eterrents:

  • Peppermint, citrus, eucalyptus, and tea tree oils – Spray in corners and along baseboards
  • Vinegar – Wipe or mist undiluted white vinegar near entry points
  • Cinnamon and cedar – Place sticks or bags in closet corners and sills
  • Citrus peels – Place on windowsills and porch steps.
  • Cedar blocks/chips – Tuck away in closets and crawlspaces.
  • Lavender sachets – Hang in entryways.

Spiders detest certain natural scents that keeps them them from going near an area. Make sure to reapply these homemade repellents frequently for ongoing effectiveness.

5. Use Insecticide Sprays

Use Insecticide Sprays

Insecticides containing pyrethrins kill arachnids on contact while repelling others. Apply around points of entry, attic entrances, and foundation gaps. Reapply after heavy rains or as directed.

Never use these chemicals on mattresses, furniture, or clothes. And keep kids and pets away until it is completely dry. Used right, these insecticides can get rid of bad invasions.

6. Use Dish Soap as Repellent

Mix a couple tablespoons of dish soap with water in a spray bottle. The soap disrupts spiders’ outer skin layer, killing them. Apply generously along baseboards, window frames, and anywhere else you see webs. Re-apply every few days to keep repelling creepy crawlies.

7. Play Loud Music

Spiders dislike loud vibrations. Place a radio, speaker, or subwoofer near problem areas and blast upbeat tunes. You can also place portable buzzers or battery-powered toothbrushes to drive them away with vibrations.

8. Use Spider Traps

Sticky traps lure spiders in and trap them on an adhesive surface. Position traps in hotspots like bends, sills, and along walls. For best results, pair traps with other deterrents like essential oils or insecticides. Traps lose stickiness over time, so replace them regularly.

9. Remove Outdoor Havens

It’s good to prevent entry to your home. But why not keep spiders off your property entirely? Prune any trees, shrubs, and plants touching your home’s exterior. Remove woodpiles, debris piles, and excess clutter near the foundation that provide hiding spots. Relocate any furniture, boxes, or shelves directly touching walls to eliminate cozy void spaces.


With some diligence and these prevention tips, you can keep your home free of cobwebs and scary spider surprises. Focus on sealing entry points, removing webs, and making your home inhospitable to these unwanted guests and other insects they feed on. As a last resort, insecticides and professional pest control can manage more severe infestations. Have patience, and you can reclaim your home from these creepy-crawly invaders.
