Florida real estate transactions often include a WDO inspection, sometimes called a termite inspection or a wood-destroying organism report. The inspection is governed by Florida Department of Agriculture and Consumer Services standards for wood-destroying organism inspections, and the scope is specific and limited.
The inspector visually examines accessible areas of the structure for evidence of four categories of wood-destroying organisms: subterranean termites (mud tubes, damaged wood, live insects), drywood termites (frass, kick-out holes, damaged wood), wood-boring beetles (exit holes, frass, larval galleries), and wood-decay fungi (soft or discolored wood indicating rot).
The key word in every part of this process is “accessible.” The inspector looks at what they can see. Foundation walls, exposed framing in garages and attics, visible wood surfaces, accessible crawl spaces, and the exterior perimeter. They do not cut into drywall. They do not move furniture or stored items. They do not remove insulation to check framing behind it. They do not dig along the foundation to check for subterranean termite tubes below grade.
In a typical Boca Raton, Boynton Beach, or Lantana home, this means large portions of the structure are not examined during the WDO inspection. The wall voids where subterranean termites actually feed. The concealed attic framing behind blown insulation. The interior of wood window frames and door frames. The structural members behind finished drywall.
A clean WDO report is genuinely useful information. It tells you that no visible evidence was found on accessible surfaces. It does not tell you that termites are absent from the structure.
Ghost ants are the most common indoor ant in South Florida, and their colonies operate across dozens of interconnected nesting sites inside wall voids, under cabinets, and in plumbing access areas. UF/IFAS documents ghost ants as among the most common structural ant pests in South Florida residences. A home inspector walking through a house for three hours will not see a ghost ant trail that is only active at 7am near the coffee maker. The buyer discovers it the first week.
Blown insulation in Florida attics conceals the wood framing where drywood termites produce frass. An inspector who accesses the attic but cannot see the framing behind the insulation cannot identify drywood activity that has not yet produced visible kick-out holes on finished surfaces. This is one of the most common post-purchase discoveries in older Boca Raton and Boynton Beach homes.
A WDO inspection catches visible mud tubes on exposed foundation walls. It does not catch subterranean termite activity inside wall voids, behind insulation, or in structural members that are not visible without removing finish materials. The invasive Formosan and Asian subterranean termites established across Palm Beach County and the Treasure Coast can cause structural damage in three to five years, and early-stage activity is frequently invisible from accessible inspection points.
Roof rats access attics through gaps as small as a quarter. Soffit gaps, unsealed utility penetrations, gaps around plumbing vents, and tree branches touching the roofline are all common entry points that a home inspector may note as minor maintenance items rather than active rodent access. The inspector is not checking for droppings in the insulation, rub marks on rafters, or gnaw marks on wiring.
German cockroaches live inside wall voids, behind appliances, and in the motor housings of refrigerators and dishwashers. A home inspector does not pull appliances away from walls or inspect inside equipment cavities. A German cockroach infestation that has been building for months or years in a previous owner's kitchen can be completely invisible during a standard walkthrough.
This is different from the WDO inspection you had at closing. A pest inspection covers the full spectrum of South Florida pest activity, not just wood-destroying organisms. The technician inspects for ant activity, roach harborage, rodent entry points, mosquito breeding conditions, and the other species the home inspection did not address.
Termite activity can develop or become visible in the months after a clean WDO report. An annual professional termite inspection is the standard recommendation for South Florida homes regardless of when the last one was done.
Look for droppings, damaged insulation, gnaw marks on wiring, and frass piles on horizontal surfaces. These are signs the home inspection may have missed, particularly in attics with heavy insulation.
Look for mud tubes on the foundation, gaps in the soffit, tree branches touching the roofline, and any opening larger than a quarter near the roofline. These are the entry points pest inspectors check and home inspectors often note only as deferred maintenance.
Many South Florida pest control companies, including Wise House, provide initial inspections that function as a comprehensive baseline for new homeowners. This is the inspection that fills the gap between what the home inspector covered and what your property actually needs.
