If you live in Middle Tennessee, chances are your home has a crawl space. It’s one of those parts of your house that’s easy to forget—out of sight, out of mind. But ignoring it can lead to some seriously unwanted surprises. Crawl spaces are prime real estate for pests, and if they move in, they can eventually make their way into your home.
Dark, damp, and tucked away, crawl spaces create the perfect environment for pests to thrive. The good news? You can take steps to protect your home. With a little sealing, cleaning, and prevention—plus a few tips from our team at All-American Pest Control—you can keep your crawl space pest-free.
What Kind of Pests Live in Crawl Spaces?
It’s not just a couple of bugs hiding out down there, it can be an entire pest party if conditions are right. Common crawl space invaders include:
-
Spiders
-
Cockroaches
-
Rodents
If your crawl space is damp, warm, or neglected, it's like rolling out the welcome mat for pests. Add in a food source, and you're practically inviting them to stay. And once they’re under your house, it’s only a matter of time before they find their way inside. That’s why keeping pests out of your crawl space is something every Middle Tennessee homeowner should focus on.
Why Sealing Your Crawl Space Matters
Sealing your crawl space isn’t just about blocking bugs—it comes with a whole list of benefits:
-
Keeps pests out
-
Improves your home’s indoor air quality
-
Reduces moisture and humidity
-
Cuts down on energy bills
-
Prevents mold and mildew growth
Depending on your comfort level with DIY projects, you can tackle some of these on your own or hire a professional. Either way, here are a few ways to start sealing up your space:
-
Use caulk or foam to seal cracks and gaps
-
Add door sweeps to crawl space access points
-
Consider full encapsulation (vapor barrier, dehumidifier, and sealing)
-
Repair or reinforce any weak or sagging access doors
How to Pest-Proof Your Crawl Space
No one wants to think about creepy crawlies—or worse, rodents—making themselves at home beneath your house. But crawl spaces can be a magnet for all kinds of pests if not properly maintained. The good news? A few proactive steps can go a long way in keeping unwanted guests out.
Start by sealing up any openings—this includes vents, gaps in the foundation walls, and spaces around pipes. Cover vent openings with hardware cloth or steel mesh to keep critters from sneaking in. It’s also a good idea to trim back shrubs and vegetation that touch or crowd your foundation, as these can offer pests a bridge into your home. And while it might seem convenient to stash pet food or old supplies down there, avoid storing anything that could serve as a food source or nesting material.
Already Seeing Mice? Here’s What to Do
If you’ve spotted droppings or heard scurrying sounds, it’s likely you’ve got mice or rats and they won’t leave on their own. Mice reproduce fast, and once they’re in, getting them out without professional help can be tough. That’s where our rodent control services at All-American come in. We’ll take care of the current problem and help prevent future infestations.
Want to stay ahead of a rodent issue? Focus on prevention. Seal off tiny entry points (mice are sneaky and can squeeze through incredibly small spaces), remove food sources like pet food or bird seed, and clear away old insulation, cardboard, or other nesting materials. Routine rodent prevention services can offer added peace of mind.
Mosquitoes in the Crawl Space? Yep, It Happens.
Most of us don’t hang out in our crawl space—but pests sure do. Moisture is the big draw, especially for mosquitoes, centipedes, and other water-loving bugs. Standing water is a mosquito’s dream breeding ground, and a damp crawl space can quickly become pest central.
To make your crawl space less inviting, drain any standing water and work on improving ventilation. Adding a vapor barrier and even fully encapsulating the space can make a huge difference. Still seeing mosquitoes or other bugs? Our MosquitoMAX pest control plan covers mosquitoes and over 47 common household pests.
Bonus Benefit: Mold & Moisture Control
Pest control isn't the only reason to keep your crawl space dry. Moisture can also lead to mold growth, which is more than just an eyesore—it can cause serious damage to your home and even impact your health. Luckily, many of the steps that help prevent pests will also help reduce mold.
To keep things dry and healthy, make sure the ground around your home drains properly. Inside the crawl space, a dehumidifier and better ventilation can improve airflow. Adding a vapor barrier and sealing foundation vents (especially if you're encapsulating the space) will go a long way in keeping moisture and mold at bay.
