WDO Inspection Florida: What Home Buyers Need to Know About Termites

Florida has the highest termite pressure of any state in the continental United States. The combination of warm temperatures, high humidity, and abundant wood construction creates ideal conditions for subterranean termites, drywood termites, and other wood-destroying organisms year-round.

If you are buying a home in Southwest Florida, a WDO inspection is not a nice-to-have — most lenders require it, and the ones that do not should not change your decision to get one. Here is everything you need to know.

WDO stands for wood-destroying organisms. A WDO inspection — also called a termite inspection or pest inspection — is a visual examination of a home for evidence of:

• Subterranean termites — the most destructive species in Florida, living in underground colonies and traveling through mud tubes to reach wood
• Drywood termites — live inside the wood itself, leaving behind small pellets called frass
• Formosan termites — an invasive subterranean species with extremely large colonies and aggressive feeding behavior
• Wood-boring beetles — including old house borers and powderpost beetles, which tunnel through structural and finish lumber
• Wood-decaying fungi — not an insect, but a biological organism that breaks down wood fiber in the presence of moisture

In Florida, WDO inspections must be performed by a licensed pest control operator holding a specific WDO license (Category 9 under Florida law). The inspector completes a standardized Florida Department of Agriculture form (FDACS-13645) that documents findings and is required by most mortgage lenders.

Studies by the University of Florida estimate that subterranean termite colonies exist in virtually every acre of Florida soil. The question is not whether termites are present near your home — they almost certainly are. The question is whether they have found a way in.

In northern states, termite activity slows significantly in winter. In Southwest Florida, there is no meaningful cold season. Termites forage and feed 12 months a year, which means damage accumulates faster and there is no natural break in activity.

Florida termites swarm — sending out winged reproductives to start new colonies — primarily in spring and early summer, though subterranean species can swarm any time of year. Swarms inside a home are a clear sign of an established infestation. Swarms outside near the foundation are a warning sign worth investigating.

Many homes in Charlotte, Sarasota, and Lee counties were built with wood framing directly on or near grade. Concrete block construction is common, but wood roof trusses, floor joists, and interior framing are still present and vulnerable. Homes with wood-to-soil contact — fence posts, deck supports, landscape timbers touching the foundation — are at elevated risk.

A licensed WDO inspector conducts a visual examination of all accessible areas of the home, including:

Exterior

• Foundation perimeter for mud tubes (subterranean termite highways)
• Wood-to-soil contact points
• Eaves, fascia, and soffit for drywood termite frass or damage
• Garage door frames and wood trim
• Attached structures: fences, decks, pergolas, sheds

Interior

• Attic — one of the most common locations for drywood termite activity
• Crawl space (if present)
• Garage walls and ceiling
• Bathrooms and kitchen areas where moisture may have softened wood
• Window and door frames
• Baseboards and floor areas near exterior walls

The inspector probes suspect areas with a tool to detect hollow or damaged wood and uses a flashlight to examine areas that are not immediately visible. Some inspectors use moisture meters to identify areas of elevated moisture that may indicate fungal activity or conditions favorable to termites.

The WDO report uses a standardized form with four possible findings for each area inspected:

1. No visible evidence — no signs of WDO activity found in this area
2. Live infestation — active WDO activity observed
3. Previous infestation — evidence of past activity with no current signs
4. Damage — structural or cosmetic damage attributable to WDO activity

The report also notes whether the home has an existing termite bond or treatment history, which is relevant to both the buyer and the lender.

A WDO inspection is a visual examination only. Inspectors cannot see inside walls, under flooring, or behind finished surfaces. This means:

• Hidden damage may not be detected — if termites have been active inside a wall cavity for years, the inspector may not find evidence unless there are visible mud tubes, frass, or surface damage
• It is not a structural assessment — the WDO inspector notes damage but does not evaluate whether that damage is structurally significant; that assessment belongs to a licensed engineer or your general home inspector
• It does not cover all pests — rodents, cockroaches, ants, and other pests are outside the scope of a WDO inspection

In the Southwest Florida market, a standalone WDO inspection typically runs $75–$150. When combined with a standard home inspection, it is often available at a reduced rate.

Given that termite damage repairs can range from a few hundred dollars for localized damage to $10,000–$50,000 or more for widespread structural damage, the inspection cost is negligible by comparison.

Finding evidence of WDO activity is not unusual in Florida — it is common. What matters is the extent of the activity and the damage.

If there is an active infestation:

• The seller is typically required to treat the home before closing
• Treatment costs vary by method: liquid soil treatment, bait stations, or tenting (fumigation for drywood termites)
• Tenting a typical Southwest Florida home costs $1,200–$2,500 and requires the occupants to vacate for 2–3 days
• You can negotiate for the seller to cover treatment costs or provide a credit

If there is prior damage with no active infestation:

• The damage may be cosmetic (damaged trim, fascia) or structural (compromised framing)
• A structural assessment may be warranted before proceeding
• Repair costs should be factored into your offer or negotiated as a credit

If there is a termite bond in place:

• A termite bond is a service contract with a pest control company that provides ongoing monitoring and treatment
• Bonds are transferable to new owners and are a significant value — ask the seller to transfer the bond at closing
• Confirm the bond is current and what it covers (monitoring only vs. treatment and repair)

A termite bond is one of the most valuable items a seller can transfer to a buyer in Florida. When reviewing a bond, confirm:

• Type of coverage — monitoring-only bonds do not cover treatment costs; treatment bonds do
• Repair coverage — some bonds include repair of damage caused by termites during the bond period; this is the most comprehensive and valuable type
• Annual renewal cost — typically $150–$400 per year
• Company reputation — verify the pest control company is licensed and in good standing with the Florida Department of Agriculture

If the home does not have a bond, you may want to establish one immediately after closing. Most pest control companies will inspect and bond a home that has been treated and cleared.

WDO inspections are typically scheduled as part of the due diligence period after a purchase contract is signed. In a competitive market, it is worth scheduling as early as possible so you have time to negotiate repairs or credits before the inspection contingency deadline.
