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

FDACS requires 75% or higher to pass its structural pest control certified operator category exams, including the fumigation category. The exam is closed-book and multiple-choice.

Which agency administers the Florida fumigation exam?

The Florida Department of Agriculture and Consumer Services (FDACS), through its Bureau of Licensing and Enforcement, administers structural pest control licensing under Chapter 482, Florida Statutes, and the implementing rule 5E-14, Florida Administrative Code.

What fumigant does the Florida fumigation category focus on?

It focuses primarily on sulfuryl fluoride (Vikane), the dominant structural fumigant since methyl bromide was phased out. Because sulfuryl fluoride is odorless, chloropicrin is added as a warning agent.

What is the reoccupancy clearance level after fumigation?

A structure may be reoccupied only when the sulfuryl fluoride concentration in the breathing zone of each room is measured at 1 ppm or less with a clearance device, after a minimum 12-hour aeration period.

What respiratory protection is required for fumigation work?

The Vikane label requires a NIOSH-approved positive-pressure SCBA or supplied-air/SCBA combination respirator above 5 ppm. Re-entry above 1 ppm or at unknown levels requires two trained persons, at least one a licensed applicator.

Is this free Florida fumigation practice test comprehensive?

Yes. It includes 100 research-based practice questions across all fumigation content areas with a teaching explanation for every answer, plus a free AI tutor. All content is free forever and updated for 2026.

The Florida Structural Pest Control Fumigation category is the FDACS specialty credential authorizing whole-structure fumigation with lethal gases, principally sulfuryl fluoride (Vikane). It is administered under the Structural Pest Control Act (Chapter 482, Florida Statutes) and rule 5E-14, Florida Administrative Code, and the closed-book multiple-choice exam requires 75% to pass. Candidates must document high school education and structural pest control experience, plus fumigation jobs for the fumigation credential. The exam tests fumigant chemistry and the chloropicrin warning agent, lethal-gas safety and positive-pressure SCBA, tarping and sealing, volume and concentration-time dosage, the minimum 12-hour aeration period and the 1 ppm clearance standard, and Florida law including warning signs, secondary locks, and recordkeeping. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Which gas is the primary active ingredient in Vikane, the most widely used structural fumigant in Florida?

A.Methyl bromide

B.Sulfuryl fluoride

C.Phosphine

D.Hydrogen cyanide

Explanation: Vikane gas fumigant is sulfuryl fluoride (SO2F2), the dominant structural fumigant in Florida since methyl bromide was phased out under the Montreal Protocol. It is a colorless, odorless gas effective against drywood termites and other structural pests.

2Because sulfuryl fluoride is odorless and colorless, what warning agent must be released into a structure before fumigation to alert anyone who enters?

A.Chloropicrin

B.Methyl mercaptan

C.Ammonia

D.Sulfur dioxide

Explanation: Chloropicrin (tear gas) is introduced as a warning agent before sulfuryl fluoride because the fumigant itself has no odor or color. Chloropicrin causes immediate eye and respiratory irritation, driving people out of a treated structure.

3What is the principal physiological effect of chloropicrin that makes it effective as a warning agent?

A.It is a powerful lachrymator causing eye and respiratory irritation

B.It produces a strong rotten-egg odor

C.It turns blue on contact with skin

D.It causes immediate drowsiness

Explanation: Chloropicrin is a lachrymator (tear gas) that causes immediate burning of the eyes and irritation of the respiratory tract at very low concentrations, forcing anyone present to leave before the lethal, odorless sulfuryl fluoride can harm them.

4Why does chloropicrin generally NOT serve as a reliable indicator that a structure is safe to reoccupy after aeration?

A.It dissipates more slowly than sulfuryl fluoride and may linger

B.It is destroyed instantly by sunlight

C.It bonds permanently to drywall

D.It dissipates faster than sulfuryl fluoride

Explanation: Chloropicrin typically dissipates more slowly than sulfuryl fluoride, so a structure can still hold detectable irritant levels even when the lethal fumigant is below clearance. Clearance is therefore determined by measuring sulfuryl fluoride with a clearance device, not by smell.

5Sulfuryl fluoride is classified as what type of pesticide because of its inhalation hazard?

A.General use pesticide

B.Restricted Use Pesticide (RUP)

C.Minimum-risk exempt pesticide

D.Biopesticide

Explanation: Sulfuryl fluoride (Vikane) is a Restricted Use Pesticide due to acute inhalation toxicity. It may only be purchased and applied by, or under the supervision of, appropriately certified and licensed applicators.

6What signal word appears on the Vikane (sulfuryl fluoride) label, reflecting its toxicity category?

A.CAUTION

B.WARNING

C.DANGER

D.NOTICE

Explanation: The Vikane label carries the signal word DANGER, the highest toxicity designation, because of its acute inhalation hazard. Fumigants of this class also bear the skull-and-crossbones and 'POISON' markings.

7A structural fumigant must penetrate wood and other materials and then leave without residue. Which property of sulfuryl fluoride best supports whole-structure penetration?

A.It is a heavy liquid that pools at floor level

B.It is a gas with strong penetrating and diffusing ability

C.It is a fine dust that coats surfaces

D.It is a foam that expands to fill voids

Explanation: Sulfuryl fluoride is a true gas at use temperatures, giving it excellent penetration and diffusion through wood, furnishings, and structural voids. This is essential to reach drywood termites deep inside wall and attic timbers.

8Sulfuryl fluoride is several times heavier than air. What operational practice does this density imply during gas introduction?

A.Fans must circulate the gas to ensure even distribution throughout the structure

B.The gas will rise to the attic on its own without help

C.No fans are needed because it spreads instantly

D.Only the ground floor needs to be treated

Explanation: Because sulfuryl fluoride is denser than air, circulating fans are run during and after introduction to mix the gas and achieve uniform concentration in upper floors and the attic. Without circulation, the gas would settle and upper areas would be under-dosed.

9Methyl bromide was largely phased out of structural fumigation primarily because it is:

A.Too expensive to manufacture

B.An ozone-depleting substance regulated under the Montreal Protocol

C.Ineffective against termites

D.Flammable and explosive

Explanation: Methyl bromide is a Class I ozone-depleting substance phased out under the Montreal Protocol and the Clean Air Act. Sulfuryl fluoride, which does not deplete stratospheric ozone, became the standard structural fumigant.

10Which pest is the most common target of whole-structure fumigation of homes in Florida?

A.Subterranean termites

B.Drywood termites

C.Carpenter ants

D.Fire ants

Explanation: Drywood termites live entirely inside dry, sound wood with no soil contact, making them difficult to reach with localized treatments. Whole-structure fumigation with sulfuryl fluoride penetrates the wood to kill colonies throughout the building.
