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. The General 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.

The pesticide label and Safety Data Sheet (SDS) are the primary sources of information about a pesticide, providing details on its use, hazards, and safety precautions. The General Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 2: Pesticide Labels) emphasizes that the first step in obtaining information is to read the label and/or SDS sheet. Option A (contact the EPA) is unnecessary for routine information, as the label/SDS is readily available. Option C (call your doctor) is relevant for medical emergencies, not general information.

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 the General Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 5: Pesticide Application).

Pesticide resistance occurs when pests develop tolerance to a pesticide due to overuse. IPM strategies, as outlined in the General 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.

For indoor applications with a handheld sprayer, low pressure is recommended to minimize overspray and reduce the risk of pesticide drift onto non-target areas, such as furniture or food surfaces. The General Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 5: Pesticide Application) advises using low-pressure settings (typically under 50 psi) for indoor crack-and-crevice or spot treatments. Option A (high pressure) and Option B (power sprayer and high) are more suited for outdoor or large-scale applications, not indoor household pest control.

Norway rats (Rattus norvegicus) are social rodents that live in colonies with a hierarchical structure, often nesting in burrows or building basements. The General 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.

Category 7A (General and Household Pest Control) includes applying pesticides to control pests like ticks and fleas inside and outside structures, including turf and ornamental areas immediately adjacent to the structure (e.g., lawns or gardens). The General Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 1: Scope of Category 7A) confirms this scope. Option A is incorrect because bedbugs are indoor pests, and grubs require Category 3B (Turf Pest Control) certification. Option B is incorrect, as 7A applicators can treat outdoor areas for certain pests like ticks and fleas.

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. The General 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.

The EPA approves pesticide labels under FIFRA, setting federal standards for use. However, states like New Jersey have the authority to impose stricter regulations if needed to protect local environments or public health. According to NJDEP Pesticide Control Program guidelines, the state can add restrictions, such as limiting application rates, requiring additional safety measures, or restricting use in certain areas (e.g., near schools or water bodies). Option A is incorrect because states can impose additional rules. Option B is incorrect because states cannot expand uses or increase rates beyond the EPA-approved label without a special local need (SLN) registration under Section 24(c) of FIFRA, which is not the same as a general modification. Option C aligns with New Jersey’s authority to enforce stricter standards.

The German cockroach is identified by two dark, parallel bands on the pronotum (shield) directly behind its head. The General Pest Management: Guide for Commercial Applicators - Category 7A (Chapter 7: Cockroaches) provides this as a key identifying feature. Option A (Oriental cockroach) is uniformly dark brown or black. Option C (Wood cockroach) is not a common indoor species and lacks these bands. Option D (American cockroach) has a different pattern, often with a yellowish figure-eight marking.
