Unwanted Guests: What Florida Home Buyers Should Know About Pest and Rodent Issues

Our warm, humid climate makes it a paradise for palm trees, beaches—and unfortunately, pests and rodents. We’ve seen firsthand how these unwelcome invaders can quietly cause serious damage to homes, degrade indoor air quality, and rack up expensive repairs for unsuspecting buyers. Below we have included some basic information we think may be helpful as you make decisions concerning your possible new home.


Common Pests and Rodents Found in Florida Homes

Our climate is ideal for many types of pests. Some are merely nuisances, while others can do real damage to the structure and safety of your future home.


Rodents: Rats and Mice

Rodents are notorious for entering attics, garages, and crawl spaces, especially in older homes or homes near wooded areas or water.


  • Damage caused: Chewed wires (fire hazard), damaged insulation, contaminated air ducts, droppings, urine, and foul odors.

  • Common signs: Gnawed corners, attic noises, droppings, or greasy smudge marks along walls.

Termites

Subterranean and drywood termites are among the most destructive pests in Florida, and they’re active year-round.


  • Damage caused: Structural wood damage, hollowed beams, sagging floors, and compromised framing.

  • Common signs: Mud tubes, frass (termite droppings), or bubbling paint on walls.

Cockroaches

German and American cockroaches thrive in warm, humid homes, especially those with plumbing leaks or food sources.


  • Damage caused: Contamination of surfaces, food, and utensils; potential allergen triggers.

  • Common signs: Droppings that resemble coffee grounds, egg cases, and strong odors.

Ants (including Carpenter Ants)

Carpenter ants don’t eat wood like termites but excavate it for nesting—causing similar damage over time.


  • Damage caused: Wood tunneling, especially in damp or decaying wood areas.

  • Common signs: Sawdust-like material near wood trim or window sills.

Spiders and Other Insects

Though most spiders are harmless, homes with lots of insects can attract predatory species, including dangerous ones like black widows or brown recluses.


Wildlife Intruders: Raccoons, Opossums, and Bats

Larger pests can enter attics or wall voids and cause extensive damage.


  • Damage caused: Torn ducts, displaced insulation, chewed wiring, and biological waste.

  • Common signs: Noises in attic at night, foul odors, or visible entry points in soffits and vents.

Problems Caused by Pest and Rodent Infestations

During home inspections, we’ve found numerous pest-related issues, including:

  • Structural weakening due to termite or carpenter ant damage

  • Unhealthy air quality from rodent droppings or mold growth due to pest-related moisture issues

  • Electrical hazards from rodents chewing through wires

  • Stained ceilings or walls from nests or fecal matter

  • Damaged insulation and HVAC systems in attic and crawl spaces

  • Soft or sagging flooring from hidden termite-damaged subflooring

These issues are often hidden from plain sight, making a professional inspection crucial.


What Buyers Should Look for When Touring a Home

While touring a used home in Florida, keep your eyes (and nose) open for signs of pest issues:


  • Musty or foul odors in closets or attics

  • Holes or chew marks in baseboards, cabinets, or attic sheathing

  • Staining on walls or ceilings

  • Signs of pest droppings in corners, behind appliances, or in garage areas

  • Live or dead insects, especially in window sills or under sinks

  • Mud tubes on exterior walls or foundation (termite activity)

If you suspect anything unusual, don’t ignore it—ask the seller directly, and then consult a licensed inspector.


How a Home Inspection Can Help

A licensed home inspector can identify current and past pest issues, assess damage, and recommend whether a specialized pest inspection is needed. Here’s how this information helps buyers:


  • Negotiation Power: If damage is found, you may be able to negotiate the price or request repairs before closing.

  • Avoiding Surprises: You’ll have a clearer understanding of any hidden issues before making a commitment.

  • Protecting Your Investment: Catching pest problems early can prevent expensive repairs down the line.


Inspections That Help You Assess Pest-Related Risks

Home inspection companies like Closer Look Inspections offer multiple inspection services to provide buyers with a full picture of the home’s condition:


General Home Inspection

Includes evaluation of visible structure, attic, crawlspaces, roof, plumbing, HVAC, and electrical—all areas where pests may be hiding or causing damage.


WDO (Wood-Destroying Organism) Inspection

Sometimes required for financing, this termite and wood-destroying pest inspection identifies current or past infestations and associated damage.


Thermal Imaging Inspection

Helps detect heat signatures that may indicate hidden pests, leaks, or decayed wood behind walls and ceilings.


Air Quality & Mold Testing

Rodents and pests can introduce allergens or contribute to mold growth—air testing can detect hidden contaminants that affect your family’s health.


Bottom Line

Pest and rodent problems in Florida homes are common—but they don’t have to catch you off guard. With the right inspections and a watchful eye, you can avoid walking into a home that hides costly, hazardous issues behind the walls. Have an inspection done. It will give you the insight to negotiate smart, budget realistically, and protect your investment from day one.
