Why Snakes Love Your North Carolina Crawl Space – And How to Keep Them Out

Mar 26, 2025 | Pest Control

Finding a snake in your crawl space is never a pleasant surprise. But why do they love these areas so much, and more importantly, how can you keep them out? For homeowners in North Carolina, understanding what attracts snakes to crawl spaces is the first step in preventing unwanted visitors.

Why Snakes Hide in Crawl Spaces

Snakes aren’t out to scare you—they’re just looking for the perfect hiding spot. Crawl spaces provide everything they need to feel hidden and secure. Here’s why your home might be attracting them:

1. Warmth and Shelter

As cold-blooded creatures, snakes rely on external warmth to regulate their body temperature. Crawl spaces offer a cozy retreat, especially during cooler months.

2. A Steady Food Supply

If you have a rodent problem, you might also have a snake problem. Mice, rats, and insects provide a food source that keeps snakes coming back.

3. Moisture and Humidity

Damp crawl spaces create the ideal environment for many snake species. If your crawl space retains moisture, it could be more inviting than you think.

4. A Quiet, Undisturbed Space

Since crawl spaces aren’t areas we frequent, they give snakes the peace and security they crave.

How to Spot a Snake Problem

Before taking action, it’s important to know if a snake has already moved in. Look for these common signs:

• Snake tracks – Wavy, zigzag patterns in dust or soft dirt
• Shed skin – Found in corners or near walls
• Rustling sounds – Subtle movements in the dark
• Droppings or odors – Snake waste resembles bird droppings and may have a musky scent
• Small holes or gaps – Tiny entry points around foundation vents, pipes, or cracks in the walls

Pro Tip: If you’re unsure about checking your crawl space, consider calling a professional for a thorough inspection.

How to Keep Snakes Out of Your Crawl Space

Once you’ve identified potential snake activity, it’s time to take action. Here’s how to snake-proof your crawl space and keep your home pest-free:

1. Seal Entry Points

Snakes can squeeze through surprisingly small gaps. Inspect your crawl space for any openings and seal them with materials like:

• Caulk or expanding foam for small cracks
• Steel mesh for vents and larger gaps
• Weather stripping around doors

2. Install a Secure Crawl Space Door

Many older homes have open or loosely sealed crawl spaces. Installing a well-fitted crawl space door can keep snakes and other pests out.

3. Reduce Attractants

A clean, dry crawl space is far less inviting to snakes. Make your home less appealing by:

• Eliminating moisture – Use a vapor barrier or dehumidifier to reduce humidity.
• Removing rodents – If you notice signs of mice or rats, call a pest control professional.
• Clearing debris – Keep woodpiles, leaves, and tall grass away from your foundation.

4. Use Snake Deterrents

Some homeowners find success with natural or chemical snake repellents. Look for options that are non-toxic for pets and follow application instructions carefully . Professional pest control services can help with distributing products such as Serpent Guard to protect your home.

5. Modify Your Landscaping

Making your yard less snake-friendly can prevent them from getting close to your home in the first place. Try these simple landscaping tips:

• Keep grass trimmed short
• Space out bushes and flowerbeds
• Use gravel or mulch—snakes dislike moving over rough textures

Keep Your Crawl Space Snake-Free for Good

North Carolina’s climate makes it a prime location for snakes, but that doesn’t mean they should be living under your home. By sealing off entry points, removing food sources, and modifying your yard, you can eliminate a snake in your crawl space—without harming them or the environment. Need help protecting your home?
