There are a few reasons why your crawl space might smell like mildew, and one of the first things to consider is the possibility of pest problems. Pests such as rodents and insects can invade crawl spaces, leaving behind waste and decomposing organic matter, which can produce a musty odor. These pests often thrive in damp areas, and their presence can lead to further moisture buildup, worsening the smell.
Another main reason for the mildew scent is excess humidity and moisture in the crawl space. This area of your home is usually cooler and more prone to dampness, especially if there are leaks, poor drainage, or inadequate ventilation. When moisture accumulates, it creates an ideal environment for mold and mildew to grow, resulting in that characteristic musty smell. Over time, mold releases spores and volatile organic compounds (VOCs) that contribute to the odor.
Additionally, organic material such as wood, insulation, or debris that gets wet can also become a breeding ground for mold. When these materials start to break down, they emit a distinct mildew odor as they decompose. In places like Nashua, New Hampshire, where humidity levels can be high, it’s crucial to keep an eye on crawl spaces for such conditions.
To sum up, the smell of mildew in your crawl space is primarily due to a combination of moisture, potential pest infestations, and the presence of organic material that fosters mold growth. This environment can significantly reduce the air quality of your home, making it important to understand its causes.

A lingering musty or mildew-like smell that gradually intensifies is often a sign of pest activity. Rodents and insects leave behind waste, nesting materials, and decomposing organic matter, all of which can produce strong odors that mix with existing moisture in the crawl space.
If you notice rodent droppings, insect debris, or shredded materials used for nests, it indicates pests are active in the crawl space. These organic leftovers can trap moisture and release unpleasant smells as they break down, contributing to a mildew-like odor.
Pests often enter through gaps where moisture is already present, and their presence can worsen humidity issues. As they move, nest, and leave waste behind, they create damp pockets that accelerate mold and mildew growth, causing the distinctive smell.
To effectively eliminate pests in your home, particularly in areas like crawl spaces, you need to follow several important steps. These will not only remove the pests but also help prevent their return.
Identify the Pests
The first step is to identify what type of pests you are dealing with. Common pests in crawl spaces include rodents, ants, termites, and cockroaches. Knowing what you're up against will help you choose the right method to eliminate them.
Seal Entry Points
Next, you should seal any openings or cracks in your home's foundation. Look for gaps around pipes, vents, and windows. Use caulk or expanding foam to fill these spaces, making it harder for pests to enter your home.
Reduce Moisture
Addressing moisture is crucial since many pests thrive in damp conditions. Make sure your crawl space has proper ventilation and consider installing a dehumidifier to keep humidity levels low. Fix any leaks and ensure that water drains away from your home's foundation.
Remove Food Sources
Keep your crawl space clean by removing any debris or organic materials that pests might feed on. Store food in airtight containers and dispose of garbage regularly.
Use Traps and Baits
For immediate pest control, set up traps or use baits specifically designed for the type of pest you're dealing with. For example, mouse traps can effectively catch rodents, while bait stations can attract and kill ants or cockroaches.
Consider Natural Remedies
If you prefer more natural methods, try using essential oils like peppermint or tea tree oil, which can repel pests. Mix these oils with water and spray them in areas where you suspect pest activity.
Seek Professional Help
If the infestation persists or is severe, consider hiring a professional pest control service. They have the tools and expertise to safely eliminate pests and identify underlying problems contributing to infestations.
By following these steps—identifying pests, sealing entry points, reducing moisture, removing food sources, using traps, considering natural remedies, and seeking help when necessary—you can effectively get rid of pests in your home and prevent them from coming back.
