Crawl Space Pests

Q: There are scratching sounds under the floor in our Ocala home—could it be rodents in the crawl space?

Yes, that’s a common sign of rodents. In Ocala, rats and mice easily enter through damaged or unsecured crawlspace doors and vent openings. Once inside, they gnaw on insulation, chew wood framing, and leave behind droppings—all hidden under your floors. LUX Foundation Solutions installs pest-proof crawlspace doors and vent covers that block access and seal vulnerable openings, giving you long-term protection from rodents and other intrusive crawl space pests.

Q: We found bugs crawling on our insulation in Gainesville—why is this happening?

Florida’s humid conditions often lead to degraded crawlspace insulation, creating the perfect habitat for crickets, roaches, and ants. These insects are attracted to moist, decaying materials and may even lay eggs inside the insulation itself. LUX replaces deteriorated insulation with closed-cell, pest-resistant insulation board and seals up entry points to prevent future nesting. This stops bugs from returning and improves your home’s comfort, cleanliness, and energy efficiency all at once.

Q: We’ve had multiple pest problems in our St. Augustine home. Could humidity in the crawl space be causing it?

St. Augustine’s coastal air means crawlspaces are often damp year-round. That excess humidity creates ideal conditions for roaches, millipedes, and centipedes to thrive and multiply. These environments also attract spiders and promote mold. LUX Foundation Solutions controls crawlspace moisture through full encapsulation and energy-efficient dehumidifiers —removing the damp conditions that pests love and protecting your home from repeat infestations with lasting, customized solutions.

Q: We noticed uneven, bouncy floors and saw pest droppings under our Ocala home—could this relate to floor joist damage?

Pests often damage wood joists from the crawlspace upward. In Ocala’s humid environment, rodents and insects chew or nest in aging floor joists, weakening them over time. If you’re noticing uneven, soft, or sagging spots in the floor along with signs of pests in your crawlspace, it could mean the joists are compromised. LUX Foundation Solutions offers floor joist sistering , reinforcing weakened joists with new lumber to restore strength and stability while keeping pests from making it worse.

Q: We saw termite damage on support beams beneath our Jacksonville home—should we be worried about structural safety?

Termites are silent destroyers, especially in Jacksonville’s moist, crawlspace environments. If you’re seeing damage to the main support beam, it could mean major structural risk for your home. Pests like termites and carpenter ants feast on damp wood, weakening your foundation’s load-bearing systems. LUX replaces damaged main beams with strong treated lumber and applies encapsulation and pest-blocking measures to stop further infestation—protecting both your home’s structure and your peace of mind.

Q: I sprayed insecticide under our Palm Coast home, but pests keep coming back—why?

DIY pest control only targets surface-level issues. In Palm Coast, open crawl space vents and poor moisture control allow new pests to return again and again. Sprays don’t fix what’s attracting them: humidity, darkness, and entry points. LUX goes beyond temporary fixes with complete crawlspace encapsulation and vent sealing , eliminating moisture and access paths. This makes your crawlspace uninviting to pests—providing long-term relief and a healthier, more secure foundation.

Q: What are the pests in the crawl space?

Crawl space pests include roaches, spiders, ants, termites, rats, mice, and more. These pests are drawn to the dark, damp environment beneath your home—often caused by open vents, standing water , or poor insulation. Crawlspace problems like these create the perfect conditions for infestations. Not sure what's crawling underneath? Schedule a free crawlspace assessment with LUX to find out.

Q: Do houses with crawl spaces have more bugs?

Yes, especially in Florida. Homes with unsealed or poorly maintained crawlspaces often see increased pest activity. Warm weather and high humidity worsen common crawlspace issues—like moisture and rotting wood—that attract bugs looking for food and shelter. If pests come back every season, your crawlspace may be the reason. Let LUX take a look.

Q: How to get rid of critters in the crawl space?

Removing pests is only part of the solution. Critters are there because of crawlspace problems like excess humidity, organic debris, or open entry points. Long-term relief comes from sealing, drying, and reinforcing the space. A professional crawlspace repair plan from LUX helps stop critters—and keeps them from coming back.

Q: Can roaches come from the crawl space?

Absolutely. Roaches often nest in crawlspaces with damp conditions, moldy insulation, or air leaks. They travel through ductwork, utility lines, and gaps into your living space. Professional crawlspace pest control removes these attractants while sealing the space to block re-entry. LUX can help identify and fix hidden infestations at the source.

Unwanted Guests Below Your Home? Pests in the Crawl Space Are More Dangerous Than You Think

If you’ve noticed odors, scratching sounds, or bugs or pests in your crawlspace, they may be invading your home. Florida’s high humidity attracts infestations that threaten your air and structure. Learn the signs, causes, and how pest activity can be stopped with expert crawl space pest solutions.

What are Crawl Space Pests?

Crawl space pests are unwanted invaders like rodents, roaches, termites, ants, crickets, and spiders that thrive in the dark, damp areas beneath your home. In Florida’s humid climate, these are especially drawn to warm, moist crawlspaces with easy entry points.

Once inside, they chew on wood, nest in insulation, and leave behind droppings that affect indoor air quality. Left untreated, these infestations can cause severe structural damage and health risks.

At LUX Foundation Solutions, we’ve helped countless Florida homeowners with expert pest control for crawlspace systems that seal, dry, and protect your home from future infestations.

Signs of Pest Infestations in a Crawl Space

Pests in crawl spaces often go unnoticed until damage or health symptoms appear. Identifying the warning signs early can help protect your home and family. In Florida, where moisture and warmth create ideal conditions for infestations, stay alert to these red flags:

Musty, foul odors seeping from vents or crawlspace.
Droppings, nests, or gnaw marks near floor joists.
Increased sightings of insects or rodents indoors.
Insulation that’s shredded, fallen, or displaced.
Warped or weakened floorboards above the crawlspace.
Insect colonies visible along wood beams.

These signs indicate pests in your crawl space may already be active. LUX Foundation Solutions provides expert assessments across Florida to stop infestations before they spread.

What Causes Crawl Space Pest Infestations in Florida Homes?

Florida’s climate creates the perfect hiding spot for pest infestations under homes. If you’re noticing pest activity, it’s often tied to hidden crawlspace issues. Here’s what could be attracting pests under your home:

Excess Moisture and Humidity

Florida’s year-round humidity creates a damp environment beneath homes. This moisture attracts cockroaches, termites, and silverfish that thrive in dark, wet places. The more prolonged the moisture lingers, the more likely crawlspaces become breeding grounds.

Open or Damaged Crawl Space Vents

Broken or uncovered vents provide an easy entry point for pests seeking shelter. In Florida’s humid climate, these openings also let in moist air, making the crawlspace more appealing to bugs and rodents looking for warmth and water.

Wood Rot and Organic Material

Rotting wood materials, decomposing insulation, and organic debris left in crawlspaces become food sources for termites, ants, and beetles. Florida’s heat and rainfall accelerate decay, making these materials even more attractive to destructive pests.

Exposed Dirt Floor

A crawlspace without a proper vapor barrier leaves bare soil exposed, allowing moisture and pests to enter freely. Florida’s damp ground releases humidity that attracts insects and rodents, while the exposed dirt provides easy access for burrowing pests to nest beneath your home.

Standing Water or Leaking Pipes

Leaky plumbing or water accumulation after heavy rainstorms creates stagnant water pools that attract pests. Rodents, mosquitoes, and water-loving insects are especially drawn to standing water in crawlspaces, where they find easy access to moisture and shelter.

Poorly Insulated Crawl Spaces

Inadequate or damaged wet insulation provides shelter and nesting material for rodents. With Florida’s fluctuating temperatures, pests seek out these comfortable, enclosed spots where they can stay protected from outdoor heat or cold.

Each of these conditions can invite pests to settle under your home. The best defense is comprehensive crawl space pest control—a long-term solution that targets the root causes of infestations rather than just removing the pests.
