How to get rid of Spiders in the Basement

In this article I will show you how to get rid of spiders in the basement. Ah, the basement – a place where we store our belongings, set up our workshops, or create cozy living spaces. Unfortunately, it’s also a favorite hiding spot for those eight-legged arachnids. Spiders can creep into our basements through the tiniest of cracks and make themselves right at home. If you’re tired of sharing your basement with these unwelcome guests, you’ve come to the right place. In this comprehensive guide, we’ll walk you through the steps to banish spiders from your basement and keep them at bay.

**1. Clean and Declutter: The First Line of Defense**

Let’s start with the basics. A cluttered basement offers plenty of nooks and crannies for spiders to hide in. By decluttering and organizing your basement, you’re essentially removing the welcome mat for these creepy crawlies. Go through your belongings, donate or discard what you no longer need, and organize what’s left. This will not only deter spiders but also make your basement a more pleasant place to be.

**2. Seal the Entry Points: Lock Them Out**

Spiders are masters at sneaking in through small openings. Your next step is to examine your basement for any cracks, gaps, or openings that might serve as spider highways. Pay special attention to walls, windows, doors, and the foundation. Seal these entry points with caulk, weatherstripping, or other appropriate materials. Not only will this help keep spiders out, but it can also improve your basement’s energy efficiency.

**3. Reduce Moisture: Dry Them Out**

Spiders are also drawn to damp environments. To discourage them, invest in a dehumidifier to lower the humidity levels in your basement. This will not only make it less appealing to spiders but also help prevent other moisture-related issues like mold. Additionally, fix any leaks or plumbing problems as soon as you discover them. A dry basement is a spider-free basement.

**4. Install Screens: Create a Barrier**

Basement windows and vents can be easy entry points for spiders. Install screens on these openings to create a barrier that keeps them out. Make sure the screens are in good condition and free from tears or holes. Regularly check and maintain these screens to ensure their effectiveness.

**5. Remove Their Food Source: Starve Them Out**

Spiders primarily feast on insects, so if you have other insect infestations in your basement, you’re essentially running an all-you-can-eat buffet for them. Address these issues promptly to eliminate the spiders’ food source. Employ natural methods like flypaper, fly traps, or light traps to capture and control other insects. Fewer insects mean fewer spiders.

**6. Regular Cleaning: Keep Their Webs at Bay**

Spiders spin webs to catch their prey, and they can quickly fill your basement with these sticky structures. To combat this, make it a habit to regularly vacuum and sweep your basement. Focus on areas where you’ve spotted spiders, corners, and any hidden spaces. Dispose of the vacuum bag or empty the canister outside to prevent spiders from making a quick escape. Consistent cleaning will deter spiders from setting up shop in your basement.

**7. Natural Repellents: Chemical-Free Solutions**

If you prefer chemical-free methods, natural repellents can be your allies in the fight against spiders. Spiders have a strong aversion to certain scents. You can create your own spider repellent sprays using ingredients like lemon or orange peels, vinegar, or essential oils such as peppermint, lavender, or tea tree oil. Mix these with water and spray the solution in areas where spiders are commonly seen. Not only will your basement smell fresh, but it will also be less inviting to spiders.

**8. Commercial Insecticides: A Last Resort**

When you’re dealing with a severe infestation, commercial spider insecticides can be an effective solution. However, it’s essential to use them with caution and strictly follow the manufacturer’s instructions. Pay close attention to safety precautions, especially if you have pets or children in the house. Prioritize the use of less toxic or eco-friendly options, and always store these chemicals in a safe, secure location.

**9. Spider Traps: Catch and Release**

Sticky traps or spider traps can be a non-toxic way to capture and reduce the spider population in your basement. Place these traps in areas where spiders are active, such as corners, along baseboards, or near their webs. Check and replace the traps regularly to maintain their effectiveness.

**10. Professional Pest Control: When All Else Fails**

If your spider infestation remains persistent and severe, or if you’re uncomfortable using chemical treatments on your own, it’s time to call in the professionals. A pest control service can assess the situation and implement effective spider control methods that are safe and tailored to your specific needs.

**Additional Tips and Advice: Keeping Spiders at Bay**

Now that you’ve learned the primary steps to rid your basement of spiders, here are some additional tips and advice to help you maintain a spider-free space:

– **Regular Maintenance:** Make basement maintenance a routine. Check for cracks and moisture issues periodically to prevent future infestations.

– **Outdoor Landscaping:** Trim back vegetation and bushes around your home’s foundation to prevent spiders from getting too close to your basement.

– **Storage Containers:** Store items in sealed containers rather than cardboard boxes. Spiders love hiding in the folds and crevices of cardboard.

– **Exterior Lighting:** Consider using yellow or sodium vapor lights for outdoor lighting. These are less attractive to insects, which, in turn, will attract fewer spiders.

– **Educate Yourself:** Learn about the common spider species in your area. Some spiders are harmless and even beneficial by eating other pests. Knowing which spiders are harmless can help you be more selective in your control efforts.

– **Regularly Inspect Outdoor Items:** Spiders can hitch a ride on outdoor items like firewood, gardening tools, or outdoor furniture. Inspect these items before bringing them into your basement.


By following these steps and tips, you can effectively banish spiders from your basement and maintain a spider-free environment. Remember that prevention is the key to long-term success. Regular maintenance, cleanliness, and proactive measures will help you enjoy your basement without the eight-legged visitors. Whether you opt for natural methods, commercial solutions, or professional assistance, you have the tools to reclaim your basement from the arachnid intruders.
