Now that you’ve got the quick fix, let’s dive into the nitty-gritty of keeping those creepy crawlies out of your basement for good.

Why Does My Basement Have So Many Spiders?

Before we kick off with the solutions, it’s important to understand why spiders are attracted to your basement. Basements offer the perfect living conditions for spiders—dark, quiet, and undisturbed. Add moisture into the mix, and you’ve created a spider’s paradise. Basements tend to attract more insects too, which serves as an abundant food source for our eight-legged friends.

Key Attractors:

• Moisture: Spiders are drawn to damp environments. Basements often have leaks, humidity, or even condensation, which makes them a prime spot for spiders. Using a dehumidifier or fixing any leaks can significantly reduce the spider population.
• Darkness: The low-light conditions in basements allow spiders to hide undisturbed. Basements are often used for storage, and items like boxes, furniture, or piles of laundry create perfect hiding spots for spiders. Without regular light or disturbance, these areas quickly become homes for many spiders.
• Food Source: The more insects in your basement, the more spiders will stick around for a free meal. Spiders prey on other bugs, and if your basement has a steady population of flies, moths, or ants, spiders will follow. To cut off their food supply, addressing any insect issues is key.

So, if your basement is cluttered with boxes, old furniture, or damp clothing, it’s like rolling out the red carpet for spiders to move in. The good news is that cleaning up can go a long way in solving this problem.

1. Clean and Declutter: Spiders Hate a Clean House

The first step in figuring out how to get rid of spiders in basement is to give the space a thorough cleaning. Spiders love hiding in dark corners and piles of clutter, so getting rid of their favorite hideouts is crucial.

Here’s a breakdown of what you need to do:

• Vacuum Regularly: Regular vacuuming is essential for removing spiders, their webs, and egg sacs. When vacuuming, focus on corners, along baseboards, and ceiling edges where spiders tend to build their webs. Don’t forget to check underneath furniture and behind stored items. It’s also a good idea to use a vacuum with a HEPA filter, as it can trap spider allergens and improve air quality.
• Remove Webs and Egg Sacs: As soon as you spot any webs or egg sacs, take them down immediately. Egg sacs can contain dozens of baby spiders that can quickly multiply into a bigger problem. Use a vacuum attachment or a broom to clear webs from corners, walls, and other areas where spiders like to build their homes. Be thorough—spiders can hide their webs in small, out-of-sight areas.
• Declutter: Toss out old cardboard boxes, unused furniture, or anything else that’s collecting dust and providing shelter for spiders. Spiders love to hide in cluttered spaces, so the more you reduce the amount of “stuff” in your basement, the fewer hiding spots they’ll have. Organize remaining items on shelves or in sealed plastic bins to minimize floor space where spiders can nest. If you’re storing clothing, use vacuum-sealed bags to prevent spiders from creeping inside.

This process doesn’t just help with spiders; it makes the space more usable for you too. By breaking the task into smaller steps, you’ll find it easier to keep your basement clutter-free long term. Once you’ve cleaned up, you’ll feel more motivated to tackle the next step.

2. Seal Entry Points: Keep Spiders from Sneaking In

Spiders are sneaky little creatures, and they’ll take any opportunity to slip into your basement through cracks, gaps, and holes. To keep them out, you need to seal all potential entry points.

Here’s how to spider-proof your basement: (How to get rid of spiders in basement)

• Inspect Your Basement Walls: Carefully examine the walls, floors, windows, and doors of your basement for any cracks or openings. Even small gaps in the foundation or around windows can be entry points for spiders. If you find any, seal them up using caulk or expanding foam. Expanding foam is particularly effective for larger gaps, as it expands to fill spaces and creates a tight seal that spiders can’t crawl through. Be diligent—check areas behind appliances, near pipes, and any place where utilities enter the house.
• Use Weather Stripping: If your basement has doors leading outside, make sure the weather stripping around the frame is tight and in good condition. Spiders can easily slip through gaps under doors, so installing door sweeps or replacing worn-out weather stripping is an inexpensive way to block their entry. Don’t forget to check the seals around your basement windows and vents. Window screens should be intact and fit snugly to prevent spiders from crawling in.
• Screen Your Windows: Make sure any basement windows are properly screened to keep spiders from crawling inside. If your current screens have holes or are loose-fitting, replace them with new, sturdy screens. Consider installing fine-mesh screens that not only block spiders but also prevent other insects, like flies and mosquitoes, from entering. Keeping out other bugs reduces the food supply that spiders rely on, making your basement less attractive to them.

By sealing these entry points, you’ll make it much harder for spiders to sneak in. This step is especially important during cooler months when spiders are seeking warmth indoors. Trust me, knowing that you’ve blocked out those creepy invaders is incredibly satisfying.

3. Repel Spiders Naturally

If you’re not a fan of using chemicals, you’re in luck. There are plenty of natural ways to repel spiders that are both effective and safe for your home. Let’s take a closer look at how to get rid of spiders in basement using natural spider repellents

Vinegar Spray

Spiders hate the smell of vinegar. To create your own spider-repelling spray, mix equal parts vinegar and water in a spray bottle. Spritz the mixture around the baseboards, windowsills, doorways, and other areas where spiders are likely to enter or linger. The strong odor of vinegar is off-putting to spiders, and regular applications can help keep them away. Be sure to reapply every week or so to maintain its effectiveness.

Essential Oils

Peppermint, lavender, and tea tree oils are natural spider repellents. To make your own spider spray, dilute 10–15 drops of essential oil in a spray bottle filled with water. Spray this mixture around the perimeter of your basement and in areas where you’ve noticed spider activity. Not only will this keep spiders away, but it also leaves your space smelling great. For an added punch, soak cotton balls in essential oils and place them in spider-prone areas, such as corners, windowsills, or inside closets.

Diatomaceous Earth

This natural powder is safe for humans but lethal for spiders and insects. Sprinkle diatomaceous earth around the perimeter of your basement, especially in cracks, gaps, and other areas where spiders might travel. When spiders come into contact with the powder, it damages their exoskeletons, causing them to dehydrate and die. Diatomaceous earth is a long-lasting solution and can be used in combination with other natural repellents for extra protection.

Natural remedies not only help to repel spiders but also create a healthier environment for you and your family. Plus, you’ll have peace of mind knowing that you’re not exposing anyone to harmful chemicals.

4. Use Spider Traps and Insecticides

If the spider population in your basement is out of control, it might be time to bring in stronger methods. Traps and insecticides can be extremely effective for getting rid of larger infestations. Read below to find out how to get rid of spiders in basement using traps and insecticides.

Sticky Traps

Sticky traps are a non-toxic solution for catching spiders. Place the traps in corners, along walls, and in areas where you’ve noticed spider activity. The sticky surface traps any spiders that come in contact with it, helping you reduce the population over time. To maximize their effectiveness, position traps in dark, hidden areas where spiders are most likely to travel. Check the traps regularly and dispose of them once they’re full, replacing them as needed to continue capturing spiders.

Insecticides

In some cases, an insecticide might be necessary. Choose a spider-specific insecticide that’s safe for indoor use. Be sure to follow the instructions carefully, especially if you have pets or kids around. Many insecticides come in spray or powder form and can be applied along baseboards, doorways, and windowsills where spiders are likely to crawl. Keep in mind that insecticides should be used as a last resort—while effective, they can introduce chemicals into your home, so always opt for safer methods first.

Although these methods might feel extreme, they are sometimes necessary when spiders seem to be multiplying faster than you can keep up with. Once you’ve tackled the 5. Maintain a Spider-Free Basement

Once you’ve cleared out the spiders, it’s essential to take steps to prevent them from returning. Regular maintenance is key to keeping your basement spider-free. Here’s what you can do:

• Regular Cleaning: Make it a habit to clean your basement every few weeks. Regular vacuuming, dusting, and wiping down surfaces will keep spiders at bay. When cleaning, focus on corners, ceilings, behind furniture, and any other dark spaces where spiders may attempt to return. Keeping the basement free of dust and debris also eliminates insects that spiders feed on, cutting off their food supply.
• Continue Using Natural Repellents: Keep using vinegar, essential oils, or diatomaceous earth to deter spiders from making a comeback. Remember that these natural repellents work best with consistent application. Reapply the sprays or place fresh cotton balls with essential oils in corners, windowsills, and other entry points every few weeks. This helps reinforce the message that your basement is not a welcoming spot for spiders.
• Check for New Cracks and Gaps: Inspect your basement every few months for any new cracks or gaps that need sealing. Over time, buildings settle and small cracks can form, creating potential entry points for spiders. Pay close attention to areas where pipes enter the home, around windows and doors, and anywhere utility lines may penetrate walls. Even small gaps can become a freeway for spiders, so sealing them up promptly is crucial.

By staying on top of these simple maintenance tasks, you’ll make it much harder for spiders to reclaim their old territory. Consistent upkeep ensures that your basement remains an uninviting place for spiders, preventing them from setting up shop in the future.
