Your Comprehensive Guide: How to Get Rid of Spiders in Your Basement for Good!
Addressing a spider infestation in your basement is essential for several reasons. Firstly, while most common house spiders are harmless, some species can bite when threatened, causing discomfort or allergic reactions.
Spiders can multiply quickly, leading to a larger infestation if not addressed promptly. Spider webs, while harmless, can contribute to a feeling of untidiness in your home.
Understanding the Common Spider Species Found in Basements
- Cellar Spiders: Commonly found in basements, cellar spiders have long, thin legs and construct irregular webs. They prey on other insects and pose little threat to humans.

Natural Remedies to Keep Spiders Away from Your Basement
1. Peppermint Essential Oil:
Spiders dislike the strong scent of peppermint, making it an excellent natural spider repellent. Here’s how to use it:
- Mix 10-15 drops of peppermint essential oil with water in a spray bottle.
- Spray the solution around your basement’s windows, doorways, and other entry points.
- Reapply the mixture weekly or as needed to maintain its effectiveness.
Besides peppermint, there are other essential oils that spiders find repulsive. Lavender, tea tree, eucalyptus, and citrus oils such as lemon or orange can be effective.
Mix a few drops of your chosen oil with water in a spray bottle and apply it to spider-prone areas. Alternatively, soak cotton balls with the oil and place them strategically around your basement.
2. Vinegar Solution:
Vinegar is an easily accessible ingredient that can deter spiders. Follow these steps:
- Mix equal parts of water and white vinegar in a spray bottle.
- Spray the solution along your basement’s baseboards, corners, and cracks.
- Repeat this process every few weeks to keep spiders at bay.
3. Citrus Peels:
Spiders dislike the scent of citrus fruits, making citrus peels an effective natural repellent. Here’s what you can do:
- Place citrus peels, such as those from oranges or lemons, near windows, doorways, or other areas where spiders are commonly seen.
- Replace the peels every few days to maintain their potency.
4. Chestnuts:
Believe it or not, chestnuts are known to repel spiders. Follow these simple steps:
- Place chestnuts in corners, windowsills, or other areas where spiders tend to gather.
- Replace the chestnuts every few weeks to ensure their effectiveness.
5. Diatomaceous Earth:
Diatomaceous earth is a natural powder composed of fossilized remains of aquatic organisms. It is harmless to humans and pets but can be effective against spiders. Here’s how to use it:
- Sprinkle food-grade diatomaceous earth around the perimeter of your basement, focusing on entry points.
- The sharp particles in diatomaceous earth can penetrate the spiders’ exoskeleton, leading to dehydration and their demise.
- Reapply the powder after vacuuming or if it gets wet.
6. Keep a Clean and Clutter-Free Basement:
Spiders are attracted to clutter and dark hiding spots.
By keeping your basement clean and clutter-free, you reduce their hiding places and make your basement less appealing to them.
Regularly vacuum and remove cobwebs to discourage spiders from taking up residence.

Tips for Preventing Future Spider Infestations in Your Basement
- Seal Entry Points: Inspect your basement for any cracks, gaps, or openings that spiders can use to enter. Seal these entry points using caulk or weatherstripping to prevent spiders from gaining access.
