Spiders In Your Garage: Causes And Solutions

The garage is a space that serves many purposes, from housing vehicles and storing belongings to serving as a workshop or a place for hobbies. Unfortunately, it’s also a common area where spiders tend to make themselves at home. If you’ve ever wondered why spiders are attracted to your garage and how to keep them at bay, you’re in the right place. In this comprehensive article, we’ll explore the causes of spiders in your garage and provide effective solutions to help you reclaim this space.

What Attracts Spiders In The House?

Before delving into the specifics of spiders in your garage, it’s essential to understand what attracts spiders in the house in the first place. Spiders are drawn to environments that provide them with the ideal conditions for survival, which include:

Food Sources: Spiders are carnivorous creatures that primarily feed on insects. If your garage is a haven for bugs, it’s likely to attract spiders looking for a steady food supply. Common garage insects include flies, mosquitoes, moths, and other small pests.

Dark and Sheltered Spaces: Spiders prefer dark and sheltered areas where they can build their webs without disturbance. Garages often provide such hiding spots, especially in cluttered or less frequently used areas.

Clutter and Debris: A messy and cluttered garage can create ideal hiding spots for spiders. Piles of cardboard boxes, old newspapers, and unused equipment can offer shelter and nesting sites for these arachnids.

Warmth and Humidity: Spiders are cold-blooded creatures and thrive in warm and humid conditions. In many regions, garages can become hot and humid, especially during the summer months, making them attractive to spiders seeking a comfortable habitat.

Lack of Maintenance: Neglected garages with cracks, gaps, and openings provide easy access for spiders. These openings also allow insects to enter, which, in turn, attracts spiders looking for a meal.

Causes Of Spiders In Your Garage:

Abundant Insect Population: Spiders are natural predators of insects, and if your garage is teeming with flies, mosquitoes, or other small pests, it’s a spider’s paradise. To address this issue, consider implementing pest control measures in and around your garage, such as using insect repellents or installing bug zappers.

Dark and Undisturbed Corners: Garages often have dimly lit and neglected corners that are perfect for spider nesting. Regularly clean and declutter your garage to eliminate hiding spots. Use brighter lighting to deter spiders from dark areas.

Unsealed Gaps and Cracks: Spiders can easily enter your garage through gaps and cracks in doors, windows, walls, and the foundation. Inspect your garage for any openings and seal them with caulk or weatherstripping to prevent spider access.

Neglected Garage Doors: Garage doors with gaps or damaged weather stripping can allow spiders to enter freely. Check that your garage doors are in good shape and repair any weather stripping that is worn out.

Poor Ventilation: Stagnant air and high humidity can attract spiders. Improve ventilation in your garage by using fans or opening windows periodically to reduce humidity levels.

Solutions To Keep Spiders Out Of Your Garage:

Regular Cleaning and Decluttering: Start by removing unnecessary items from your garage. Decluttering not only creates a less inviting environment for spiders but also makes it easier to spot and address any potential issues.

Seal Entry Points: Inspect your garage for gaps around doors, windows, and other openings. Spiders can’t get in if you fill in any gaps or holes with glue or weatherstripping.

Install Weather Stripping: Ensure that your garage doors are equipped with tight-fitting weather stripping. Replace damaged or worn weather stripping to create a barrier against spider intrusion.

Use Pest-Repelling Plants: Planting spider-repelling herbs and flowers, such as lavender, mint, or marigolds, near your garage can discourage spiders from making themselves at home.

Regular Pest Control: Consider scheduling regular pest control treatments for your garage and the surrounding areas. Professional pest control services can assist in eliminating and preventing future spider infestations.

Improve Lighting: Install bright, white lights in your garage to deter spiders from dark corners. Spiders prefer dimly lit areas, so well-lit spaces are less appealing to them.

Reduce Humidity: Use dehumidifiers or fans to maintain a lower humidity level in your garage. Spiders thrive in high-humidity environments, so reducing moisture can make the space less attractive to them.

Storage Solutions: Store items in airtight containers to prevent spiders from nesting in cardboard boxes or behind clutter. This also helps with general organization and pest prevention.


Spiders in your garage can be a nuisance, but by understanding the causes and implementing effective solutions, you can reclaim this space and make it less inviting for these eight-legged intruders. Regular maintenance, pest control, and a clean, well-lit environment are key to keeping spiders at bay and ensuring that your garage remains a functional and pest-free area of your home.
