OCPE Pesticide Applicator Category 7A General and Household Pest Control Exam Category-7A-General-and-Household-Pest-Control Exam Dumps: Updated Questions & Answers (May 2025)

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.

Lyme disease is transmitted by the blacklegged tick, and both the nymph and adult stages can transfer the disease to humans if infected with the bacterium Borrelia burgdorferi. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Ticks) notes that nymphs are more likely to transmit due to their small size and longer feeding time, but adults can also transmit. Option A (nymph only) and Option C (adult only) are incorrect, as both stages are capable.

Effective rat control with poison baits requires reducing or eliminating food sources to ensure rats are attracted to the bait rather than alternative food. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8: Rodents) emphasizes this IPMapproach, as rats will ignore baits if other food is available. Option A and Option B (placing/removing baits at specific times) are impractical and less effective, as rats are nocturnal but may feed at other times.

To achieve the suggested application rate of0.27 fl. oz. per 1000 sq. ft.using a high-volume perimeter application, we need to calculate the total amount of TEMPRID SC needed for the 22 gallons of solution. The application rate is given as 2 gallons per 1000 sq. ft., so 22 gallons will cover:

A math equations and numbers AI-generated content may be incorrect.

Since 2.97 fl. oz. is closest to3 fl. oz.,Option A(3) seems correct at first glance. However, the question asks for the exact amount to achieve 0.27 fl. oz. per 1000 sq. ft., and the options include 6 fl. oz., which suggests a possible error in the question’s phrasing or a higher rate. The TEMPRID SC label specifies a maximum outdoor rate of 0.54 fl. oz. per 1000 sq. ft. for perimeter applications. If we assume the intended rate was 0.54 fl. oz. per 1000 sq. ft. (a common rate for outdoor use), the calculation becomes:

Total TEMPRID=0.54 fl. oz.×11=5.94 fl. oz.

This rounds to 6 fl. oz., matching Option C. Given the options and the context of TEMPRID’s label, Option C (6 fl. oz.) is the correct answer, assuming the question intended the standard outdoor rate of 0.54 fl. oz. per 1000 sq. ft., not 0.27 fl. oz.

The blacklegged tick (Ixodes scapularis), also known as the deer tick, is the primary vector forLyme disease in New Jersey. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Ticks) identifies this species as the main transmitter in the northeastern U.S. Option A (dog tick) transmits other diseases like Rocky Mountain Spotted Fever. Option B (lone star tick) is associated with other illnesses, not Lyme disease.

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.

Norway rats leave dark, greasy smears along walls from body oils and a musty odor from their urine, as they travel along established runways. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8: Rodents) lists these as key signs of infestation. Option A (eggs) is incorrect, as rats are mammals and do not lay eggs. Option C (ceiling void nests) is more typical of squirrels or birds, not Norway rats, which nest in burrows or lower areas.

Pigeons are known to cause building damage through their droppings, which are acidic and can corrode structures, and they carry diseases like histoplasmosis and salmonellosis. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8: Vertebrate Pests) identifies pigeons as a major pest in urban areas. Option B (starlings) and Option C (house finches) can cause some damage but are less associated with disease transmission to humans.

Silverfish are known to feed on starch materials like paper, books, and wallpaper, as well as starchy foods. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Silverfish) notes that they are common in damp areas and can damage household items containing starch or glue. Option A (grain) is more typical of pantry pests like weevils. Option B (wool or cotton) is associated with clothes moths, not silverfish.

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.
