NEW QUESTION # 33
The most common cockroach found in buildings is the ___ cockroach.
- A. Brown-banded
- B. American
- C. German
Answer: C
Explanation:
The German cockroach (Blattella germanica) is the most common cockroach found in buildings, particularly in kitchens and bathrooms, due to its preference for warm, humid environments and rapid reproduction. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 7: Cockroaches) identifies the German cockroach as the most prevalent indoor species in the
U.S., including New Jersey. Option A (American cockroach) is larger and more common in sewers or basements. Option B (Brown-banded cockroach) is less common and prefers drier areas.
NEW QUESTION # 34
If you wear contacts, ___ when handling pesticides.
- A. Wear a face shield
- B. Do not wear them
- C. Wear goggles
Answer: B
Explanation:
Contact lenses can trap pesticide residues against the eye, increasing the risk of irritation or injury if exposure occurs. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 3: Pesticide Safety) advises applicators to not wear contact lenses when handling pesticides to avoid this risk. Option A (face shield) and Option B (goggles) are protective measures for the eyes but do not address the specific hazard of contact lenses trapping chemicals.
NEW QUESTION # 35
Which of the following rodents is considered to live in colonies rather than individual territories?
- A. House mouse
- B. White-footed mouse
- C. Norway rat
Answer: C
Explanation:
Norway rats (Rattus norvegicus) are social rodents that live in colonies with a hierarchical structure, often nesting in burrows or building basements. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8: Rodents) describes their colonial behavior. Option A (white- footed mouse) and Option B (house mouse) are more solitary or live in smaller family groups, not large colonies.
NEW QUESTION # 36
The wasp most likely to sting is the:
- A. Yellow jacket
- B. Mud dauber
- C. Honeybee
Answer: A
Explanation:
Yellow jackets are aggressive social wasps and are the most likely to sting, especially when their nest is disturbed. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter
7: Wasps) notes their defensive behavior. Option A (honeybee) can sting but typically only once, as they die after stinging. Option C (mud dauber) is a solitary wasp and less likely to sting unless provoked.
NEW QUESTION # 37
Carpenter ants:
- A. Feed on the chewed wood from their cavities
- B. Make transportation tubes from the chewed wood
- C. Discard the wood from their galleries
Answer: C
Explanation:
Carpenter ants excavate wood to create galleries for nesting but do not feed on it; they discard the wood as sawdust-like frass outside their galleries. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Ants) notes that this frass is a key sign of carpenter ant activity. Option A (feed on the wood) is incorrect, as they feed on insects and sugary substances.
Option B (make transportation tubes) applies to termites, not carpenter ants.
NEW QUESTION # 38
The most common cause of pesticide poisoning to the applicator is:
- A. Oral ingestion
- B. Dermal exposure
- C. Inhalation
Answer: B
Explanation:
The most common cause of pesticide poisoning for applicators is dermal exposure, where pesticides contact the skin during mixing, application, or cleanup. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 3: Pesticide Safety) highlights that skin exposure often occurs during mixing procedures or application, especially if proper protective equipment is not used.
Option A (inhalation) is the second most common cause (see Question 16). Option B (oral ingestion) is less common, typically occurring through accidental ingestion or poor hygiene practices.
NEW QUESTION # 39
Power sprayers:
- A. Need an annual calibration
- B. Need to have their calibration checked to ensure the proper amount of pesticide is being delivered
- C. Are pre-calibrated at the factory and further calibration is not necessary
Answer: B
Explanation:
Power sprayers must be calibrated to ensure the correct amount of pesticide is applied, as application rates can vary due to wear, nozzle changes, or pressure adjustments. TheGeneral Pest Management:
Guide for Commercial Applicators - Category 7A(Chapter 5: Pesticide Application) stresses that applicators should check calibration regularly to ensure accuracy, especially for Category 7A applications. Option A is incorrect because factory calibration does not account for field conditions or equipment changes. Option C (annual calibration) is a good practice but not a strict requirement; the need for calibration depends on usage and equipment condition.
NEW QUESTION # 40
The suggested method for earwig control is an:
- A. Exterior treatment along with debris removal along the foundation
- B. Interior baseboard residual spray
- C. Interior and exterior foundation fogging
Answer: A
Explanation:
Earwigs are outdoor pests that enter structures, often hiding in debris near foundations. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Earwigs) recommends exterior treatment (e.g., perimeter spraying) combined with debris removal to eliminate harborage sites. Option A (fogging) is not a standard method for earwigs. Option B (interior baseboard spray) may be used but is less effective without addressing outdoor sources.
NEW QUESTION # 41
The recertification requirements for a commercial pesticide applicator are:
- A. 16 credits per category and 8 credits core within 5 years
- B. 8 credits core, 24 credits in a category within 3 years
- C. 80 dollars per year
Answer: A
Explanation:
NJDEP requires commercial pesticide applicators to recertify every five years. For Category 7A applicators, this involves earning 8 credits in Core (general pesticide safety and regulations) and 16 credits in each category (e.g., 7A) within that five-year period (N.J.A.C. 7:30-6.4). Option A is incorrect because the category credits are 16, not 24, and the timeframe is five years, not three. Option B (80 dollars per year) is irrelevant to recertification credits, though there may be fees for licensing.
NEW QUESTION # 42
The Consumer Information Notice must contain the:
- A. Applicator business name, address, and phone number
- B. Business license number
- C. Commercial applicator's license number and phone number
Answer: A
Explanation:
The Consumer Information Notice, required by NJDEP (N.J.A.C. 7:30-9.13), must include the applicator business name, address, and phone number to provide residents with contact information for inquiries or concerns. Option A (applicator's license number) is not required on the notice, though the business license number may be included. Option B (business license number) is not a mandatory element of the notice, though it may be displayed on the vehicle.
NEW QUESTION # 43
FIRST AID for TEMPRID if swallowed includes:
- A. Sipping water if conscious but no induced vomiting unless told to do so by poison control center or doctor
- B. Giving sips of water even if victim is unconscious
- C. Inducing vomiting if conscious
Answer: A
Explanation:
The TEMPRID SC label provides first aid instructions: if swallowed, the victim should sip water if conscious, but vomiting should not be induced unless directed by a poison control center or doctor. This aligns with standard pesticide safety protocols in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 3: Pesticide Safety). Option A (inducing vomiting) can be dangerous without professional guidance. Option B (giving water if unconscious) is incorrect, as no liquids should be given to an unconscious person.
NEW QUESTION # 44
To help prevent pesticide resistance, IPM suggests:
- A. Use of multiple components in the control of a pest population
- B. Routine preventative spraying
- C. Increased dosage to knock out initial infestation
Answer: A
Explanation:
Pesticide resistance occurs when pests develop tolerance to a pesticide due to overuse. IPM strategies, as outlined in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 4: IPM), recommend using multiple components (e.g., rotating pesticide classes, incorporating non-chemical methods like sanitation or traps) to control pests and reduce resistance risk. Option A (routine spraying) increases resistance by overexposing pests to the same chemical. Option C (increased dosage) can exacerbate resistance and is not an IPM practice.
NEW QUESTION # 45
The yellow jacket is a:
- A. Solitary wasp nesting in the ground
- B. Ant with wings
- C. Social bee usually nesting in trees
- D. Social wasp usually nesting in the ground
Answer: D
Explanation:
Yellow jackets are social wasps that typically nest in the ground, often in abandoned rodent burrows or other cavities. They live in colonies with a queen and workers, as described in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Wasps). Option B (social bee) is incorrect, as yellow jackets are wasps, not bees, and they do not typically nest in trees. Option C (solitary wasp) is incorrect, as yellow jackets are social. Option D (ant with wings) is incorrect, as yellow jackets are distinct from ants.
NEW QUESTION # 46
The most common poisonous spider in New Jersey is the:
- A. Black Widow
- B. Orb Weaver
- C. Brown Recluse
Answer: A
Explanation:
The black widow (Latrodectus mactans) is the most common poisonous spider in New Jersey, known for its neurotoxic venom. TheGeneral Pest Management: Guide for Commercial Applicators - Category
7A(Chapter 7: Spiders) notes that black widows are more prevalent in the state, often found in dark, sheltered areas. Option A (orb weaver) is not venomous to humans. Option C (brown recluse) is rare in New Jersey, with few confirmed sightings, and is more common in the Midwest.
NEW QUESTION # 47
State pesticide regulations regarding pesticide service vehicles require the:
- A. Commercial pesticide applicator's license number be on the vehicle
- B. Pesticide storage area be physically separate from the driver or passengers
- C. MSDS sheets for all pesticides be on board the vehicle
Answer: B
Explanation:
NJDEP regulations (N.J.A.C. 7:30-9.10) require that pesticide service vehicles have a storage area for pesticides that is physically separate from the driver or passenger compartment to prevent exposure in case of spills or leaks. This is a safety measure to protect the driver and ensure compliance with transportation regulations. Option B is incorrect because, while the business registration number is required on the vehicle (see Question 8), the applicator's license number is not. Option C is incorrect because, although having Safety Data Sheets (SDS, formerly MSDS) on board is a best practice, it is not a strict requirement under NewJersey law for service vehicles; SDS sheets must be available at the business location or application site.
NEW QUESTION # 48
A carcinogen is a material that causes:
- A. Birth defects
- B. Teratogen
- C. Cancer
Answer: C
Explanation:
A carcinogen is a substance that can cause cancer, as defined in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 3: Pesticide Safety). Some pesticides are classified as carcinogens due to their potential to cause cancer with long-term exposure. Option B (birth defects) is associated with teratogens, not carcinogens. Option C (teratogen) is incorrect because a teratogen is a substance that causes birth defects, not cancer, and the term itself is not the definition.
NEW QUESTION # 49
Carbamate and pyrethroid pesticides are:
- A. Nonpoisonous
- B. Stomach/digestive poisons
- C. Nerve poisons
Answer: C
Explanation:
Carbamate and pyrethroid pesticides are both classes of insecticides that act as nerve poisons. They target the nervous system of pests, disrupting nerve function and leading to paralysis and death.
Carbamates inhibit cholinesterase enzymes, while pyrethroids affect sodium channels in nerve cells.
This is detailed in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 6: Pesticide Types). Option A (stomach/digestive poisons) is incorrect, as these pesticides primarily act through contact or inhalation, not ingestion. Option B (nonpoisonous) is incorrect, as both are toxic to pests and potentially harmful to humans if mishandled.
NEW QUESTION # 50
Which rodent requires a daily water source?
- A. House mouse
- B. Deer mouse
- C. Norway rat
Answer: C
Explanation:
Norway rats require a daily water source to survive, often living near water or in areas with high moisture. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8:
Rodents) notes this as a key characteristic, making water sources a target for control. Option B (house mouse) and Option C (deer mouse) can survive on moisture from food and do not require a daily water source.
NEW QUESTION # 51
Swarming ants and termites are similar, but the termite:
- A. Has bent antennae
- B. Does not have a waist
- C. Has a narrow waist
Answer: B
Explanation:
Swarming termites and ants can be distinguished by physical characteristics. Termites do not have a waist, as their body is broad and straight, while ants have a narrow, pinched waist. Additionally, termites have straight antennae, whereas ants have bent (elbowed) antennae. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Termites vs. Ants) highlights these differences. Option A (bent antennae) applies to ants, not termites. Option C (narrow waist) also describes ants, not termites.
NEW QUESTION # 52
The certified commercial pesticide applicator is ___ pesticide operator.
- A. Jointly liable for all violations committed by any
- B. Responsible for the minimum annual retraining required for a
- C. All of the answers are applicable
- D. Responsible for the proper training of a
Answer: C
Explanation:
Under NJDEP regulations (N.J.A.C. 7:30-6.2 and 7:30-5.2), a certified commercial pesticide applicator overseeing a pesticide operator has multiple responsibilities. Option A: The applicator is jointly liable for violations committed by the operator under their supervision, as they are responsible for ensuring compliance with all pesticide laws. Option B: The applicator must ensure the operator receives proper training, which includes initial training on safe pesticide use, handling, and application techniques as outlined in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 1:
Legal Responsibilities). Option C: Annual retraining is also required to maintain competency and stay updated on regulations, a requirement for operators under the supervision of a certified applicator (NJDEP guidelines). Since all these responsibilities apply, Option D is correct.
NEW QUESTION # 53
Power sprayers are not used for:
- A. Exterior perimeter and lawn applications
- B. Termite applications
- C. Interior house ant and roach applications
Answer: C
Explanation:
Power sprayers are designed for high-volume applications over large areas, such as exterior perimeter and lawn applications (Option B) or termite applications (Option C), where large amounts of pesticide are needed. However, they are not suitable for interior house ant and roach applications (Option A), as these require precise, low-volume treatments (e.g., crack-and-crevice applications) using handheld sprayers, as noted in theGeneral Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 5: Pesticide Application).
NEW QUESTION # 54
The suggested re-entry interval for applications of TEMPRID is:
- A. Wait until treated area is dry
- B. 24 hours
- C. 12 hours
Answer: A
Explanation:
The TEMPRID SC label specifies that the re-entry interval for treated areas is to wait until the treated area is dry, typically 1-2 hours under normal conditions, unless otherwise specified for specific uses.
This ensures that the pesticide has settled and there is no risk of exposure to wet residues. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 5: Pesticide Application) aligns with this guidance for most indoor applications. Option A (24 hours) and Option C (12 hours) are incorrect, as they exceed the label's re-entry requirement unless specified for a specific situation (e.
g., in schools, where additional restrictions may apply).
NEW QUESTION # 55
Bait stations confine toxic substances to removable units. Their successful use depends on their:
- A. Placement
- B. Harborage
- C. Application as a dab of material
Answer: A
Explanation:
Bait stations are effective for controlling pests like roaches or rodents when placed in areas where pests are active, such as near food sources or nesting sites. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 5: Pesticide Application) emphasizes that placement is critical for success, as improper placement reduces pest contact with the bait. Option A (harborage) refers to pest hiding spots, not bait station use. Option B (application as a dab) applies to gel baits, not bait stations.
NEW QUESTION # 56
For non-powered particulate filters, which letter represents the most resistance to oil degradation?
- A. N
- B. R
- C. P
Answer: C
Explanation:
Non-powered particulate filters are classified by NIOSH with letters indicating oil resistance: N (not resistant to oil), R (resistant to oil), and P (oil-proof, most resistant to oil degradation). TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 3: Pesticide Safety) explains that P filters offer the highest resistance to oil degradation, making them suitable for environments where oil-based aerosols may be present. Option A (N) offers no oil resistance, and Option C (R) offers moderate resistance but not as much as P.
