Spider Control in Basements and Attics: Tips for a Creepy-Crawly-Free Space

Spiders are a common sight in basements and attics, where they find ideal conditions to spin their webs and hide from the hustle and bustle of everyday life. While many spiders are harmless and even beneficial, their presence can still be unsettling for many homeowners. In this blog post, we will discuss effective strategies for spider control in basements and attics, helping you reclaim these spaces and make them less inviting to our eight-legged friends.

Understanding Spiders in Basements and Attics

Before diving into spider control methods, it’s essential to understand why spiders are drawn to basements and attics in the first place. These areas offer several favorable conditions for spiders:

·       Darkness:

Basements and attics are typically dark, making them suitable for nocturnal spiders that prefer low-light environments.

·       Stagnant Air:

These spaces often have poor ventilation, leading to stagnant air, which some spider species prefer.

·       Prey Availability:

Insects are attracted to basements and attics due to the availability of moisture and hiding spots, which, in turn, attracts spiders seeking to feed on them.

·       Hidden Nooks and Crannies:

Spiders can easily find secluded spots to build their webs and lay their eggs without disturbance.

Now, let’s explore effective methods for spider control in basements and attics.

1. Declutter and Organize

Begin your spider control efforts by decluttering and organizing the space. Remove items that are no longer needed, as clutter provides spiders with additional hiding spots. Store items in sealed plastic containers rather than cardboard boxes, as spiders can easily hide in the crevices of cardboard.

2. Seal Entry Points

Spiders enter basements and attics through gaps and cracks in walls, windows, doors, and foundation. Inspect the space carefully and seal any potential entry points:

  • Caulk gaps and cracks in walls and windows.
  • Install weather stripping around doors.
  • Ensure screens on windows and vents are in good repair.

3. Proper Ventilation

Improve the ventilation in your basement and attic to reduce stagnant air, making it less appealing to spiders. Installing vents or using fans can help maintain airflow and reduce humidity levels, discouraging spider activity.

4. Reduce Moisture

Moisture attracts insects, which in turn attract spiders. Take steps to reduce moisture levels in these spaces:

  1. Fix any leaks or water seepage promptly.
  2. Use a dehumidifier to maintain optimal humidity levels.
  3. Ensure proper drainage and gutter maintenance to prevent water from accumulating near your home’s foundation.

5. Regular Cleaning

Regularly clean and vacuum your basement and attic to remove dust, debris, and spider webs. Pay attention to corners, crevices, and hidden spaces. Vacuuming not only removes spiders but also their eggs and prey.

6. Natural Spider Repellents

Some natural substances can deter spiders:

  1. Peppermint oil: Mix water with a few drops of peppermint oil and spray it in spider-prone areas.
  2. Vinegar: A mixture of vinegar and water (1:1) can be used as a cleaning solution to deter spiders.
  3. Citrus peels: Place citrus peels, such as lemon or orange, in spider-prone areas, as spiders dislike the scent.

7. Spider Traps

Use spider traps or sticky traps strategically placed in areas with high spider activity. These traps capture spiders when they walk over them.

8. Outdoor Prevention

Prevent spiders from entering your home in the first place by keeping the surrounding area clear of tall vegetation and debris. Trim bushes and trees that touch your home, reducing spider access points.

9. Professional Pest Control

If your spider infestation is persistent or extensive, consider seeking professional pest control services. Pest control experts can assess the situation and provide targeted treatments to eliminate spiders and their nests.


Basements and attics are often overlooked areas of the home, but they can become breeding grounds for spiders if left unchecked. By understanding why spiders are drawn to these spaces and implementing effective prevention and control strategies, you can reclaim your basement and attic from these eight-legged intruders. Whether you choose natural repellents, spider traps, or professional pest control, a spider-free environment is within reach, ensuring that your home remains a comfortable and inviting place for your family and guests.
