Question 1Laws, Regulations, and Licensing Requirements

Under California law, which branch of structural pest control covers the control of wood destroying pests and organisms such as termites and wood-decay fungi?

  1. Branch 4
  2. Branch 2
  3. Branch 3 Correct answer.
  4. Branch 1

Explanation

Branch 3 covers the control of wood destroying pests and organisms, including termites, wood-boring beetles, and wood-decay fungi. Fumigation is classified as Branch 1 and general household pest control as Branch 2.

Question 2Laws, Regulations, and Licensing Requirements

Fumigation of a structure to control drywood termites is classified under which branch of structural pest control?

  1. Branch 1 Correct answer.
  2. Branch 4
  3. Branch 2
  4. Branch 3

Explanation

Branch classification in California follows the method of work used. Fumigation is Branch 1 work even when the target pest is a wood destroying organism that would otherwise fall under Branch 3.

Question 3Laws, Regulations, and Licensing Requirements

The regulations adopted by the Structural Pest Control Board to implement the Structural Pest Control Act are published in which code?

  1. California Building Standards Code
  2. California Code of Regulations Correct answer.
  3. Uniform Plumbing Code
  4. Health and Safety Code

Explanation

The Act itself is codified in the Business and Professions Code, and the Board's implementing regulations appear in Title 16 of the California Code of Regulations.

Question 4Laws, Regulations, and Licensing Requirements

Which entity issues structural pest control licenses in California?

  1. Department of Pesticide Regulation
  2. Contractors State License Board
  3. County agricultural commissioner
  4. Structural Pest Control Board Correct answer.

Explanation

The Structural Pest Control Board licenses companies, operators, and field representatives under the Structural Pest Control Act. County agricultural commissioners and the Department of Pesticide Regulation play other roles in pesticide regulation.

Question 5Laws, Regulations, and Licensing Requirements

Before a person may perform structural pest control work for hire, the person must:

  1. hold a license issued under the Structural Pest Control Act Correct answer.
  2. complete a four-year apprenticeship
  3. register with the county agricultural commissioner
  4. obtain a permit from the Department of Pesticide Regulation

Explanation

The Act prohibits performing structural pest control work for compensation without a license issued by the Board. Unlicensed practice is unlawful and subject to enforcement action.

Question 6Laws, Regulations, and Licensing Requirements

Which statement about advertising by a registered structural pest control company is correct?

  1. The license number must appear in the advertisement Correct answer.
  2. Advertisements may describe the firm as 'Board approved'
  3. License numbers may be left out of newspaper advertisements
  4. Only the operator's name must be shown in advertisements

Explanation

Advertising for structural pest control services must show the company's license number so that consumers can verify that the firm is licensed. Descriptions implying official approval by the Board are improper.

Question 7Laws, Regulations, and Licensing Requirements

A structural pest control contract solicited and signed at the customer's home generally gives the customer a right to cancel within:

  1. seven calendar days
  2. three business days Correct answer.
  3. twenty-four hours
  4. ten business days

Explanation

A contract solicited and signed at the consumer's residence is a home solicitation contract, and California law gives the buyer three business days to cancel. The cancellation right must be explained to the customer.

Question 8Laws, Regulations, and Licensing Requirements

The Structural Pest Control Board is a regulatory body within which state department?

  1. Department of Toxic Substances Control
  2. Department of Food and Agriculture
  3. Department of Public Health
  4. Department of Consumer Affairs Correct answer.

Explanation

The Board is housed within the Department of Consumer Affairs, which oversees California's consumer protection licensing boards. It is not part of the agricultural or public health agencies.

Question 9Laws, Regulations, and Licensing Requirements

On the Board's wood destroying pest inspection report form, findings showing an existing infestation or damage that requires correction are reported in:

  1. the cost allocation summary
  2. the supplemental narrative
  3. Section I Correct answer.
  4. Section II

Explanation

Section I of the report lists findings that require correction, such as active infestation or damage. Section II lists conditions that are conducive to infestation but are not themselves an existing infestation.

Question 10Laws, Regulations, and Licensing Requirements

A Branch 3 inspection report must be prepared:

  1. on a form supplied by the county
  2. in any format chosen by the licensee
  3. on a form prescribed by the Board Correct answer.
  4. on the contractor's letterhead only

Explanation

Reports of wood destroying pest inspections must be made on forms prescribed by the Board so that findings are reported consistently and consumers can compare reports. A free-form narrative alone does not satisfy the requirement.

Question 11Laws, Regulations, and Licensing Requirements

After completing a Branch 3 treatment job, the licensee must furnish the customer with:

  1. a notice of work completed Correct answer.
  2. a verbal summary of the work performed
  3. a written warranty covering all treated areas for one year
  4. a copy of the pesticide label only

Explanation

When the work is finished, the licensee must give the customer a notice of work completed that identifies the work actually performed. The notice documents what was done compared with what was recommended.

Question 12Laws, Regulations, and Licensing Requirements

Wood repair work identified in a Branch 3 report may be performed by:

  1. any employee of the company that prepared the report
  2. the real estate agent handling the transaction
  3. a licensed contractor Correct answer.
  4. the field representative who signed the report

Explanation

Carpentry and other structural repair work is contracting work and must be done by a contractor licensed under the Contractors State License Law. Holding a pest control license does not by itself authorize repair work.

Question 13Laws, Regulations, and Licensing Requirements

Which task may an unlicensed employee of a registered structural pest control company perform?

  1. signing inspection reports
  2. making wood destroying pest inspections
  3. office clerical work Correct answer.
  4. applying pesticides without supervision

Explanation

Unlicensed employees may handle clerical and other non-pest-control duties. Inspections, pesticide applications, and signing reports are licensed activities under the Act.

Question 14Laws, Regulations, and Licensing Requirements

A registered structural pest control company that performs Branch 3 work must:

  1. employ at least five licensed field representatives
  2. employ a licensed Branch 3 operator Correct answer.
  3. hold licenses in all three branches
  4. be owned by a licensed field representative

Explanation

A registered company must have a licensed operator responsible for each branch of work it performs. A company may hold only the branches it actually engages in.

Question 15Laws, Regulations, and Licensing Requirements

A person who violates the Structural Pest Control Act may face which criminal consequence?

  1. an infraction only
  2. a felony conviction
  3. no criminal penalty
  4. a misdemeanor Correct answer.

Explanation

Violations of the Act are punishable as misdemeanors. The Board's own authority is administrative, but criminal exposure exists separately.

Question 16Laws, Regulations, and Licensing Requirements

Which action may the Board take against a licensee who violates the Act?

  1. place the license on probation Correct answer.
  2. impose criminal fines without court action
  3. revoke the company's pesticide registrations
  4. seize the licensee's equipment without a hearing

Explanation

The Board's disciplinary authority includes suspending, revoking, or placing a license on probation, and issuing citations. It does not impose criminal fines or cancel pesticide product registrations.

Question 17Laws, Regulations, and Licensing Requirements

A licensee who changes the business address must:

  1. notify the Board in writing of the change Correct answer.
  2. wait until the next license renewal to report it
  3. file a new license application
  4. notify only the county agricultural commissioner instead

Explanation

Licensees must keep the Board informed in writing of address changes so that official notices and correspondence reach them. Failing to do so can result in missed renewal or disciplinary notices.

Question 18Laws, Regulations, and Licensing Requirements

Before a registered company begins Branch 3 work on a customer's property, the company should:

  1. notify the Board of the scheduled work
  2. obtain written authorization from the customer Correct answer.
  3. obtain verbal approval from the customer
  4. post a notice on the property seven days in advance

Explanation

Work should not proceed without the customer's written authorization, which establishes the scope of the work agreed to. Verbal approval leaves no record of what was authorized.

Question 19Laws, Regulations, and Licensing Requirements

Which practice is a violation of the Structural Pest Control Act?

  1. advising the customer to obtain a second opinion
  2. recommending treatment based on the licensee's findings
  3. knowingly misstating the extent of an infestation Correct answer.
  4. providing a copy of the report to the person who requested it

Explanation

The Act prohibits false or misleading statements in connection with structural pest control work. Knowingly overstating or understating an infestation is a deceptive practice subject to discipline.

Question 20Laws, Regulations, and Licensing Requirements

A company that holds only a Branch 3 license receives a request to control cockroaches in a restaurant. The company:

  1. may perform the work as an incidental service
  2. may perform the work if a Branch 3 operator supervises
  3. may perform the work after notifying the Board
  4. must hold a Branch 2 license to perform that work Correct answer.

Explanation

Control of general household pests such as cockroaches is Branch 2 work. A Branch 3 license authorizes wood destroying organism work only, so the company would need a Branch 2 license to do the job.

Question 21Laws, Regulations, and Licensing Requirements

A company holds only a Branch 3 license but contracts to fumigate a home for drywood termites. To perform the fumigation lawfully, the company must:

  1. hold a Branch 1 license or use a licensed Branch 1 company Correct answer.
  2. have the fumigation supervised by a Branch 3 operator
  3. use a fumigant registered for wood destroying pests and organisms
  4. obtain a variance from the Board before fumigating

Explanation

Fumigation is Branch 1 work, and a company may only perform it if it holds a Branch 1 license or if a properly licensed Branch 1 company performs the fumigation. A Branch 3 license does not authorize fumigation regardless of the target pest.

Question 22Laws, Regulations, and Licensing Requirements

During a real estate inspection, an inspector documents a Section II condition. The seller's agent asks the inspector to remove it because the seller will not make repairs. The inspector should:

  1. reword the finding as a recommendation
  2. leave the finding unchanged in the report Correct answer.
  3. defer to the agent's judgment
  4. remove the finding at the seller's request

Explanation

The report must accurately reflect the conditions the licensee observed. Findings may not be deleted or softened at the request of a party who stands to benefit from the change, because that would be a false or misleading report.

Question 23Laws, Regulations, and Licensing Requirements

Compliance with California's pesticide use laws and regulations during a structural pest control application is enforced locally by which of the following?

  1. the Structural Pest Control Board
  2. the Department of Real Estate
  3. the Contractors State License Board of California
  4. the county agricultural commissioner Correct answer.

Explanation

County agricultural commissioners are the local enforcement agency for pesticide use laws and regulations. The Structural Pest Control Board's role centers on licensing and practice standards rather than pesticide use enforcement.

Question 24Laws, Regulations, and Licensing Requirements

A field representative's license expires, but the person continues performing Branch 3 inspections for a registered company. Which statement is correct?

  1. The inspections remain valid because the company is licensed
  2. The person is engaged in unlicensed practice Correct answer.
  3. The company may ratify the inspections afterward
  4. The person may continue until the Board sends notice

Explanation

A license must be current when the work is performed. Once it expires, the individual is performing structural pest control work without a license regardless of the company's own license status.

Question 25Laws, Regulations, and Licensing Requirements

A licensed Branch 3 field representative is between jobs and is not employed by any registered company. May the person perform Branch 3 inspections for a fee?

  1. Yes, if the person reports each inspection to the Board
  2. Yes, because the field representative license is current
  3. No, unless a Branch 2 licensee co-signs the report
  4. No, unless a registered company employs the person Correct answer.

Explanation

A field representative practices as part of a registered structural pest control company that has a responsible licensed operator. A valid license alone does not authorize independent practice outside a registered company.

Question 26Laws, Regulations, and Licensing Requirements

Under the Structural Pest Control Act, which branch of licensing covers the inspection for and control of wood destroying pests such as termites, wood-boring beetles, and wood decay fungi?

  1. Branch 1
  2. Branch 3 Correct answer.
  3. Branch 2
  4. Branch 4

Explanation

The Act divides structural pest control into three licensing branches: Branch 1 for fumigation, Branch 2 for general pest control, and Branch 3 for wood destroying pests and organisms. Inspection, reporting, and treatment of termites, wood-boring beetles, and wood decay fungi fall within Branch 3.

Question 27Laws, Regulations, and Licensing Requirements

A registered company assigns an employee to inspect a home for wood destroying pests and to sign the resulting inspection report. Which credential must that employee hold?

  1. A registered pest control adviser license
  2. A Branch 2 applicator license
  3. A field representative license Correct answer.
  4. A county agricultural commissioner's permit

Explanation

Wood destroying pest inspections and the reports that document them must be made and signed by an individual licensed as a field representative (or an operator). An applicator credential authorizes pesticide applications but not the preparation of inspection findings.

Question 28Laws, Regulations, and Licensing Requirements

A company headquartered in another state holds no California license. It is hired to perform a wood destroying pest inspection on a California home. Before doing the work, the company must:

  1. have its inspection report co-signed by a California licensed real estate broker
  2. obtain a California contractor's license and file a surety bond with the county
  3. give the county agricultural commissioner at least 10 days' written notice of the visit
  4. register with the Board as a structural pest control company Correct answer.

Explanation

Structural pest control work performed on California property may only be done by or through a company registered with the Structural Pest Control Board, regardless of where the company is based. Out-of-state status does not substitute for registration, and the company's personnel must hold the appropriate California licenses.

Question 29Laws, Regulations, and Licensing Requirements

A homeowner believes that a registered structural pest control company failed to perform the wood destroying pest work it promised. The homeowner may pursue the complaint with:

  1. The county agricultural commissioner
  2. The Structural Pest Control Board Correct answer.
  3. The Better Business Bureau
  4. The Contractors State License Board

Explanation

The Structural Pest Control Board licenses and disciplines registered companies and their personnel, and it receives and investigates consumer complaints about work performed under the Act. The Board may also offer mediation or arbitration of disputes.

Question 30Laws, Regulations, and Licensing Requirements

Before treating soil for subterranean termites, a Branch 3 licensee concludes that the labeled rate of the chosen termiticide is too low for the soil conditions at the site. Which action is legally permitted?

  1. Applying twice the labeled rate to offset the heavy soil conditions
  2. Applying a higher rate as long as the higher rate is written in the company's job file
  3. Applying a higher rate after the property owner signs a written consent
  4. Applying the product at a rate within the range shown on the label Correct answer.

Explanation

A registered pesticide may be used only in a manner consistent with its labeling, and the labeled rate is the maximum permitted regardless of site conditions. Using a product at a rate above the label is a misuse of the pesticide even with customer approval or internal documentation.

Question 31Fumigant Chemistry, Toxicology, and Label Comprehension

Which active ingredient is the structural fumigant sold under the trade name Vikane?

  1. Methyl bromide
  2. Chloropicrin
  3. Sulfuryl fluoride Correct answer.
  4. Aluminum phosphide

Explanation

Vikane is the registered trade name for sulfuryl fluoride, a colorless, odorless gas used mainly against drywood termites and other structural pests. Methyl bromide, chloropicrin, and aluminum phosphide are separate active ingredients with their own products and labels.

Question 32Fumigant Chemistry, Toxicology, and Label Comprehension

Why is chloropicrin added to some otherwise odorless fumigants?

  1. To lower the vapor pressure of the gas
  2. To neutralize residues after aeration
  3. To provide a tear-producing warning odor Correct answer.
  4. To increase penetration into wood

Explanation

Chloropicrin is a powerful lachrymator, so even trace concentrations irritate the eyes and give workers warning of a gas that would otherwise be undetectable by smell. It does not change penetration, vapor pressure, or residues in any useful way.

Question 33Fumigant Chemistry, Toxicology, and Label Comprehension

Aluminum phosphide formulations release phosphine gas when they are exposed to:

  1. Moisture Correct answer.
  2. Sunlight
  3. Carbon dioxide
  4. Dry air

Explanation

Aluminum phosphide reacts with water to form phosphine gas and aluminum hydroxide, which is why the product must be kept dry and tightly sealed until use. Dry air alone, sunlight, and carbon dioxide do not drive that hydrolysis.

Question 34Fumigant Chemistry, Toxicology, and Label Comprehension

A fumigant with a vapor density greater than 1.0:

  1. Dissipates upward toward the attic
  2. Mixes uniformly regardless of release point
  3. Tends to settle into lower areas Correct answer.
  4. Becomes flammable at low concentrations

Explanation

Vapor density compares a gas to air; a value above 1.0 means the gas is heavier than air and will drift and collect in low spots such as basements and crawlspaces. That is why release points and monitoring locations are chosen with density in mind.

Question 35Fumigant Chemistry, Toxicology, and Label Comprehension

Half-loss time is best defined as the:

  1. Interval required to seal and tape the structure
  2. Point halfway through the total exposure period
  3. Exposure period needed to kill the target pest
  4. Time for the gas concentration to halve Correct answer.

Explanation

Half-loss time measures how quickly a fumigant leaks or is sorbed out of the enclosure by recording the interval in which the measured concentration falls to half its value. It is used to judge how well the structure is sealed and how the dosage must be adjusted.

Question 36Fumigant Chemistry, Toxicology, and Label Comprehension

Which statement must appear prominently at the top of a restricted-use pesticide label?

  1. General Use Pesticide
  2. Low Toxicity Formulation
  3. Restricted Use Pesticide Correct answer.
  4. For Organic Production Only

Explanation

Federal labeling rules require the phrase Restricted Use Pesticide at the top of the label so the buyer immediately knows the product may be applied only by or under the supervision of a certified applicator. The other phrases are not required label statements for restricted materials.

Question 37Fumigant Chemistry, Toxicology, and Label Comprehension

On a fumigant label, the signal word DANGER together with the word POISON and a skull-and-crossbones symbol indicates that the product is:

  1. Corrosive to metal only
  2. In the highest toxicity category Correct answer.
  3. Exempt from PPE requirements
  4. A mild eye irritant

Explanation

The combination of DANGER, POISON, and the skull and crossbones is used for products in the most acutely toxic category, typically those with a very low oral, dermal, or inhalation LD50/LCL50. Products in that category carry stringent personal protective equipment and handling requirements.

Question 38Fumigant Chemistry, Toxicology, and Label Comprehension

Which property of sulfuryl fluoride makes it particularly dangerous inside a treated structure?

  1. It is colorless and essentially odorless Correct answer.
  2. A sharp garlic odor at low levels
  3. A visible white haze that obscures vision
  4. A sweet smell that workers might mistake for solvent

Explanation

Sulfuryl fluoride has no odor or color to warn occupants and workers, so a person can be exposed without realizing it and must rely on monitoring rather than the senses. Clearance measurements and posted warnings replace odor as the safety signal.

Question 39Fumigant Chemistry, Toxicology, and Label Comprehension

A structure encloses 24,000 cubic feet. The label dosage is 1 pound per 1,000 cubic feet. How much fumigant is needed?

  1. 240 pounds
  2. 2.4 pounds
  3. 12 pounds
  4. 24 pounds Correct answer.

Explanation

Dosage is applied per unit of enclosed volume, so divide 24,000 by 1,000 to get 24 units and multiply by 1 pound per unit, giving 24 pounds.

Question 40Fumigant Chemistry, Toxicology, and Label Comprehension

A phosphine detector tube in a work area reads 0.6 ppm. The OSHA permissible exposure limit for phosphine is 0.3 ppm. The reading is:

  1. One-half the PEL
  2. Twice the PEL Correct answer.
  3. Ten times the PEL
  4. Equal to the PEL

Explanation

Dividing the measured 0.6 ppm by the 0.3 ppm limit gives a value twice the permissible exposure limit, so workers must leave the area and corrective action is required.

Question 41Fumigant Chemistry, Toxicology, and Label Comprehension

Which fumigant is a strong methylating agent that reacts with sulfur-containing materials such as rubber and leather?

  1. Carbon dioxide
  2. Sulfuryl fluoride
  3. Phosphine
  4. Methyl bromide Correct answer.

Explanation

Methyl bromide readily transfers a methyl group to sulfur-containing compounds, which is why it can damage rubber, leather, and photographic materials and is also part of how it injures cells. Sulfuryl fluoride is comparatively inert toward such materials.

Question 42Fumigant Chemistry, Toxicology, and Label Comprehension

Fumigation is generally less effective in a cold structure because low temperature:

  1. Increases the vapor density of the gas
  2. Reduces both vapor pressure and insect activity Correct answer.
  3. Prevents the gas from diffusing at all
  4. Eliminates the need to seal the structure

Explanation

Cold temperatures lower a fumigant's vapor pressure and slow the metabolism and movement of the target pests, so the gas works more slowly and often requires a longer exposure or an adjusted label dose. Diffusion still occurs, and sealing is always required.

Question 43Fumigant Chemistry, Toxicology, and Label Comprehension

For a fumigant heavier than air, the practical release and monitoring plan is to:

  1. Release high in the structure and monitor low areas Correct answer.
  2. Release at mid-height and monitor only outdoors
  3. Release outside the building and monitor indoors
  4. Release low and monitor the attic

Explanation

Heavier-than-air gases sink, so releasing the gas at the upper part of the enclosure allows it to fall through the space, and monitoring is concentrated at low points where the gas accumulates.

Question 44Fumigant Chemistry, Toxicology, and Label Comprehension

A worker is most likely to detect chloropicrin used as a warning agent by:

  1. A distinctive garlic odor
  2. A metallic taste in the mouth
  3. Tearing and eye irritation Correct answer.
  4. A visible blue cloud

Explanation

Chloropicrin is a strong lachrymator, so the earliest warning is stinging eyes and tears, which appear at concentrations far below those that would injure a person. That irritant effect is the reason it is used as a warning agent.

Question 45Fumigant Chemistry, Toxicology, and Label Comprehension

When fumigant concentrations inside a structure may be high or unknown, entry requires:

  1. A dust/mist respirator
  2. No respirator if the entry lasts under one minute
  3. A self-contained breathing apparatus Correct answer.
  4. A single-strap half-mask cartridge respirator

Explanation

Air-purifying respirators rely on a filter or cartridge and cannot supply oxygen or handle unknown or high concentrations, so entry into a fumigated space requires a positive-pressure self-contained breathing apparatus. Short duration does not make an unprotected entry acceptable.

Question 46Fumigant Chemistry, Toxicology, and Label Comprehension

Occupants may not re-enter a structure fumigated with sulfuryl fluoride until the concentration has been reduced to:

  1. 10 ppm or less
  2. 25 ppm or less
  3. 1 ppm or less Correct answer.
  4. 50 ppm or less

Explanation

The sulfuryl fluoride label requires aeration until monitoring shows 1 ppm or less throughout the structure before occupants and workers may re-enter without respiratory protection. The clearance reading must be documented as the label directs.

Question 47Fumigant Chemistry, Toxicology, and Label Comprehension

During a fumigation the measured concentration falls far faster than the calculated half-loss time predicted. Which explanation is most likely?

  1. An application dosage far above the label rate
  2. An increase in the thermal conductivity of the gas
  3. Adsorption of the gas by porous contents and materials Correct answer.
  4. Generation of additional gas by the contents

Explanation

Porous commodities, wood, and building materials take up fumigant and remove it from the free air, so measured concentrations drop more quickly than leakage alone would predict. The response is to reset the seal and add gas only as the label permits.

Question 48Fumigant Chemistry, Toxicology, and Label Comprehension

The principal acute health effects of sulfuryl fluoride exposure are:

  1. Photosensitivity with skin blistering
  2. Blood clotting abnormalities and jaundice
  3. CNS depression and respiratory irritation Correct answer.
  4. Cholinesterase inhibition and excessive salivation

Explanation

Sulfuryl fluoride is a central nervous system depressant and respiratory irritant, and severe exposure can lead to pulmonary edema and fluoride-related effects. Cholinesterase inhibition and photosensitization are effects of other pesticide classes.

Question 49Fumigant Chemistry, Toxicology, and Label Comprehension

A fumigator measures 128 ounces of fumigant at release and 32 ounces six hours later. Assuming first-order loss, the half-loss time is about:

  1. 6 hours
  2. 12 hours
  3. 3 hours Correct answer.
  4. 1.5 hours

Explanation

Falling from 128 to 32 ounces is a fourfold decrease, which represents two halvings (128 to 64 to 32) in six hours, so each halving takes about three hours. Half-loss time is reported per halving, not for the whole interval.

Question 50Fumigant Chemistry, Toxicology, and Label Comprehension

Why must a structure be thoroughly sealed before the fumigant is released?

  1. To keep insects from escaping during the exposure
  2. To protect interior finishes from the gas
  3. To prevent rain from entering the structure
  4. To hold the gas at a lethal level during exposure Correct answer.

Explanation

Sealing limits leakage so a lethal concentration can be sustained for the full exposure period required by the label. Without an adequate seal, gas is lost faster than planned and the treatment may fail.
