Buying a new home is one of the biggest investments you will ever make, and pest problems can quietly drain thousands of dollars from that investment if they go unnoticed. From hidden termite damage and rodent activity in the attic to bed bugs in the carpet or wildlife nesting in the chimney, pests can affect both the value of the home and the safety of your family. A standard home inspection rarely covers every pest issue, so understanding what to look for—and what to ask—before closing is essential. This guide breaks down the pests to know about when buying a new home and how to protect yourself.
Why a Pest Inspection Matters Before You Buy
A general home inspection focuses on structural elements, plumbing, electrical, and roofing—but it rarely includes a thorough pest evaluation. Florida’s warm, humid climate creates ideal conditions for termites, ants, rodents, and wildlife year-round. A separate Wood-Destroying Organism (WDO) report and pest inspection can reveal hidden infestations, past damage, and current activity that affects your offer, financing, and long-term costs. Skipping this step can lead to expensive repairs within months of moving in. Always make pest inspections part of your due diligence before finalizing any home purchase in Florida.
Common Pests to Check for When Buying a New Home
1. Termites
Termites cause more than $5 billion in U.S. property damage every year, and Florida is one of the highest-risk states. Subterranean, drywood, and Formosan termites all live throughout the state. Look for mud tubes on foundation walls, hollow-sounding wood, blistered paint, discarded wings near windowsills, and tiny piles of pellet-like droppings. A clean WDO report doesn’t guarantee a termite-free future, so consider a transferable bond or annual treatment plan to protect your investment after closing.
2. Rodents (Mice and Rats)
Rodents leave clear signs: droppings in the attic or pantry, chewed wires, greasy rub marks along baseboards, and shredded insulation. Roof rats are especially common in Florida, often entering through soffits, vent gaps, and palm trees touching the roofline. Check the attic, garage, and crawl spaces thoroughly. Rodent infestations damage HVAC systems, contaminate insulation, and increase fire risk by chewing wiring. Ask whether the home has been treated and request documentation of any rodent exclusion work.

3. Cockroaches
German, American, and smoky brown cockroaches all thrive in Florida homes. They hide behind appliances, under sinks, in cabinets, and inside cardboard storage. Look for droppings (small dark specks), egg casings, a musty odor, and shed skins. Roaches trigger allergies and asthma, especially in children. A heavy infestation often signals deeper sanitation or moisture issues that may also affect plumbing or the foundation. Ask about pest control history and any recurring treatment patterns.
4. Ants and Carpenter Ants
Florida is home to fire ants, ghost ants, sugar ants, and carpenter ants. While most are nuisance pests, carpenter ants tunnel through wet wood, weakening structural beams over time. Check around door frames, window sills, and exterior trim for sawdust-like debris (called frass). Anthills around the foundation or yard suggest persistent activity. Identifying the species matters—fire ants pose a health risk, while carpenter ants signal moisture damage that should be inspected by a professional.
5. Bed Bugs
Bed bugs can hide in carpets, baseboards, electrical outlets, and even behind wallpaper—surviving for months without feeding. They are not tied to cleanliness, so any previously occupied home is at risk. Look for tiny dark spots on mattress seams (if the home is staged), small reddish stains, or shed skins along baseboards. Eradicating bed bugs after move-in is expensive and often requires heat treatment. Ask the seller whether bed bug treatment has ever been performed.

6. Bats and Birds
Wildlife in the attic or chimney is a Florida hot-spot issue. Bats roost in soffits, gable vents, and behind fascia boards, while birds nest in chimneys, dryer vents, and roof eaves. Both leave droppings that pose serious health risks—bat guano can contain histoplasmosis spores, and bird droppings can carry several diseases. Look for staining around vents, listen for activity at dusk, and check the attic for guano or feathers. Removal must follow legal guidelines, especially with protected species.
7. Squirrels and Raccoons
Squirrels chew through soffits, fascia, and roof returns to nest in attics, often damaging insulation and wiring. Raccoons rip open vents, climb chimneys, and create messy latrines in attics. Both can carry parasites and disease. During a walkthrough, listen for daytime scratching (squirrels) or heavier nighttime movement (raccoons). Inspect roof returns, dormers, and attic vents from outside the home. Any sign of nesting requires professional wildlife removal and structural repair before closing.
8. Mosquitoes and Standing Water
Florida’s mosquito problem is amplified by clogged gutters, decorative ponds, birdbaths, leaky outdoor faucets, and improperly graded yards. Walk the property and look for standing water near the foundation, in gutters, AC drip pans, and under bushes. Mosquitoes carry Zika, West Nile virus, and Eastern equine encephalitis. Improper drainage also signals possible foundation moisture issues. Ask whether the yard has ongoing mosquito treatment and inspect downspouts and irrigation systems carefully before purchase.

9. Spiders
Most Florida spiders are harmless, but black widows and brown recluses are present in some areas. Heavy spider populations usually indicate a larger insect problem—spiders go where prey is plentiful. Check garages, crawl spaces, sheds, and corners of porches for webs. While spiders alone aren’t typically a deal-breaker, dense webs and egg sacs suggest the home has not been regularly treated and may have underlying pest issues that need attention after move-in.
10. Fleas and Ticks
If the previous owners had pets, the home may have residual flea or tick activity. Fleas can lie dormant in carpets for months before emerging when new occupants move in. Inspect carpeting, pet areas, and yard edges for signs. Florida’s warm climate means ticks remain active year-round, especially in shaded landscaping. Ask whether pets lived in the home, what flea prevention was used, and whether the yard has been treated recently.
Where to Look During a Home Walkthrough
- Attic: droppings, urine stains, chewed insulation, nesting material, moisture
- Crawl space: mud tubes, water damage, fungus, animal entry
- Basement/garage: rodent droppings, gnaw marks, stored items with damage
- Kitchen and pantry: roach droppings, ant trails, pellet-shaped frass
- Bathrooms: moisture damage, silverfish, mold
- Exterior: soffit gaps, vent screens, mulch contact with siding, foundation cracks
- Yard: standing water, ant mounds, animal trails, overgrown vegetation
Red Flags That Should Pause a Purchase
- Visible termite damage, mud tubes, or frass deposits
- Strong ammonia or musty odors in the attic or walls
- Rodent droppings in multiple rooms
- Animal scratching or activity heard during walkthroughs
- Heavy pesticide residue suggesting recurring infestations
- Sellers unwilling to provide pest treatment history
- Damaged or makeshift attic vents and soffits
Questions to Ask the Seller
Get specifics before closing. Ask whether the home has had any termite, rodent, or wildlife treatments; whether a transferable termite bond exists; what pest control company services the property; and whether any active infestations have been treated in the last five years. Request the most recent WDO report and ask for written documentation of repairs or exclusion work. Sellers in Florida are typically required to disclose known material defects, but pest history may not always be volunteered without direct questions.
How a Professional Pest Inspection Protects You
A licensed pest inspector evaluates the home for active and past infestations, conducive conditions (moisture, wood-to-soil contact, debris), and likely entry points for wildlife. The inspector’s written report becomes a negotiating tool: you can request repairs, a treatment credit, or even walk away if the infestation is severe. Pest control experts also recommend ongoing maintenance plans that fit the home’s risk profile, helping you avoid surprise costs after move-in. Combining a pest inspection with a structural inspection gives you the clearest picture before signing.
Get a Professional Inspection Before You Buy
Don’t close on a home without a separate pest and wildlife inspection. The National Pest Management Association recommends a dedicated pest inspection for every home purchase, especially in high-risk states like Florida. WildOut provides thorough pre-purchase wildlife and pest inspections that go beyond standard WDO reports, including attic checks, exclusion assessments, and treatment recommendations tailored to your future home.
Conclusion
Pests can quietly turn your dream home into a money pit if they aren’t identified before closing. By knowing what to look for, asking the right questions, and ordering a professional pest inspection, you protect both your investment and your family’s health. From termites and rodents to wildlife and bed bugs, every Florida home has unique pest risks that deserve attention. Take the time now—long before signing—to evaluate the property carefully. A few hundred dollars spent on inspections can save you thousands in repairs and treatments down the road.
FAQs
Is a pest inspection different from a home inspection?
Yes. A standard home inspection focuses on structure and systems. A pest inspection (or WDO report) specifically evaluates termite, wood-destroying organism, and other pest activity.
Who pays for the pest inspection?
It depends on the contract, but in many Florida transactions the buyer pays for inspections, while sellers may pay for any required treatments before closing.
Should I walk away from a home with termite history?
Not necessarily. If the damage was repaired and a transferable termite bond is in place, the home may still be a smart purchase—just verify everything in writing.
How long does a pest inspection take?
Most inspections take 1–2 hours, depending on the home’s size, attic access, and outbuildings on the property.
What if I find pests after closing?
You may have limited recourse if the issue wasn’t disclosed or detected in your inspection. Treatment costs typically fall on the new owner, which is why a thorough inspection is essential.
