What does the Florida WDO (Termite) category certification allow?

The Termite & Other Wood-Destroying Organisms category, under Chapter 482, Florida Statutes, authorizes WDO inspections, issuing the Form 13645 WDO inspection report, and performing termite and other wood-destroying organism treatments. It is administered by FDACS and is separate from the general household pest and agricultural pesticide programs.

What score do I need to pass the Florida WDO exam?

You need 70% to pass. Candidates must pass both the 50-question General Standards (Core) exam and the Termite & WDO category exam, each at 70%, through FDACS.

How many questions are on the Florida WDO exam?

FDACS does not publish a single fixed count for the WDO category exam, but the General Standards (Core) exam has 50 multiple-choice questions, and the WDO category exam is a separate multiple-choice exam. Both require 70% to pass.

What are the eligibility requirements for the WDO certification?

The common pathway is a high school education or equivalency plus three years of experience as a service employee of a licensee in the category sought; a combination of qualifying education and experience is also accepted. You must hold a valid FDACS identification card to perform pest control work.

Is the WDO category the same as Florida's agricultural pesticide license?

No. The WDO category is a structural pest control certification under Chapter 482, while the agricultural pesticide applicator program is separate. Structural pest control covers work in, on, and under structures, including termite inspections and treatments.

Is this free Florida WDO practice as good as paid prep?

Our 100 practice questions cover the same domains as the WDO category exam, including termite biology, soil and bait treatments, Form 13645 reporting, chemistry and safety, and Chapter 482 law, with a teaching explanation for every answer plus free daily AI tutor help.

FDACS

The Florida Termite & Other Wood-Destroying Organisms (WDO) category is the FDACS structural pest control certification, under Chapter 482, Florida Statutes, and Rule 5E-14, F.A.C., that authorizes wood-destroying organism inspections, Form 13645 WDO reports, and termite treatments. To certify, a candidate passes the 50-question General Standards (Core) exam and the multiple-choice WDO category exam, each requiring 70%, and typically documents a high school education plus three years of category experience. The WDO category is distinct from Florida's agricultural pesticide applicator program and from the General Household Pest category. Content spans termite and WDO biology and identification, soil termiticide treatments and baiting systems, Form 13645 inspection reporting, pesticide chemistry and safety, and Florida structural pest law and consumer protection. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Which genus of subterranean termite is the most economically destructive invasive species in South Florida and is known for building large carton nests and aggressive foraging?

A.Reticulitermes

B.Coptotermes (Formosan)

C.Kalotermes

D.Incisitermes

Explanation: The Formosan subterranean termite (Coptotermes formosanus) and the Asian subterranean termite (Coptotermes gestroi) are highly aggressive invasive subterranean termites that cause more structural damage in South Florida than all other wood-destroying organisms combined. Coptotermes colonies can number in the millions and build aerial carton nests.

2What is the primary diagnostic evidence used to identify an active subterranean termite infestation during a Florida WDO inspection?

A.Six-sided fecal pellets (frass)

B.Mud (shelter) tubes

C.Round emergence holes 1/8 inch wide

D.Surface blistering of paint only

Explanation: Subterranean termites require soil moisture and build mud (shelter) tubes of soil and feces to travel between the ground and wood while remaining protected. Mud tubes on foundation walls, piers, and slab penetrations are the classic sign of subterranean termite activity.

3Drywood termites are distinguished from subterranean termites primarily by which biological characteristic?

A.They require contact with soil for moisture

B.They live entirely within the wood and need no ground contact

C.They build mud tubes across foundations

D.They are not capable of flight

Explanation: Drywood termites (family Kalotermitidae, e.g., Incisitermes and Cryptotermes) live entirely inside dry, sound wood and obtain moisture metabolically, so they need no contact with soil or external moisture. This is why they are found in attics, furniture, and wood far above ground level.

4The small, hard, six-sided fecal pellets that accumulate in small piles beneath infested wood are the hallmark sign of which pest?

A.Subterranean termites

B.Drywood termites

C.Carpenter ants

D.Wood-decaying fungi

Explanation: Drywood termites push their distinctive six-sided fecal pellets (frass) out of small kick-out holes, where the pellets accumulate in piles below the infestation. The concave sides and uniform shape of the pellets are a definitive identification feature.

5In a termite colony, which caste is responsible for foraging, feeding the colony, and causing essentially all of the wood damage?

A.Soldiers

B.Workers

C.Alates (reproductives)

D.The queen

Explanation: Worker termites are the sterile, wingless caste that forages for cellulose, feeds the colony through trophallaxis, and does the actual wood-consuming damage. Soldiers defend the colony and reproductives produce offspring, but neither feeds itself or damages wood.

6A winged termite swarmer (alate) can be distinguished from a winged ant by which feature?

A.Two pairs of wings of equal length and a broad waist

B.A narrow, pinched waist and elbowed antennae

C.Only one pair of wings

D.Wings much shorter than the body

Explanation: Termite alates have four wings of equal length and shape, straight (beaded) antennae, and a broad waist with no constriction. Ants, by contrast, have a pinched (constricted) waist, elbowed antennae, and forewings longer than hindwings.

7Which wood-destroying organism is characterized by tiny round emergence holes and very fine, flour-like frass that sifts out of the holes?

A.Old house borer

B.Lyctid (true) powderpost beetle

C.Carpenter bee

D.Subterranean termite

Explanation: Lyctid powderpost beetles attack the sapwood of hardwoods and produce very fine, talc-like frass that flows freely from small (about 1/32 to 1/16 inch) round exit holes. The flour-fine consistency of the frass distinguishes them from other wood borers.

8Under Florida WDO terminology, the old house borer primarily attacks which type of wood?

A.Hardwood sapwood

B.Seasoned softwood (coniferous) framing lumber

C.Decayed, fungus-softened wood

D.Tropical hardwoods only

Explanation: The old house borer (Hylotrupes bajulus) is a longhorned beetle that infests seasoned softwood (coniferous) lumber such as pine framing. Larvae make a rasping sound while tunneling and leave oval exit holes with tightly packed, blunt-ended frass pellets.

9Wood-decaying (brown-rot and white-rot) fungi require which condition to actively degrade structural wood?

A.Wood moisture content generally above about 28-30%

B.Completely dry wood below 8% moisture

C.Direct sunlight on the wood surface

D.Soil temperatures below freezing

Explanation: Wood-decay fungi need free water and generally become active when wood moisture content exceeds roughly 28-30% (above the fiber saturation point). Controlling moisture intrusion and keeping wood dry is the primary means of preventing and arresting fungal decay.

10Why are subterranean termite colonies generally far more damaging to a structure than drywood termite colonies?

A.Subterranean colonies are much larger and contain many more foraging workers

B.Drywood termites cannot digest cellulose

C.Subterranean termites bore larger individual galleries

D.Drywood termites only eat painted surfaces

Explanation: Subterranean termite colonies, especially Coptotermes, can contain hundreds of thousands to millions of individuals and forage across wide areas, consuming wood rapidly. Drywood colonies are confined to the wood they infest and typically number only a few thousand, so they damage wood much more slowly.
