Category-7A-General-and-Household-Pest-Control Exam Dumps - OCPE Pesticide Applicator Questions and Answers

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). TheGeneral 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.

The second most common cause of pesticide poisoning for applicators is inhalation, as pesticides can be inhaled as vapors, mists, or dusts during mixing or application, especially in enclosed spaces. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 3: Pesticide Safety) notes that inhalation exposure often follows dermal exposure (the most common cause, see Question 18) in frequency. Option A (fire) is not a common cause of poisoning, though it poses other risks. Option C (dermal exposure) is the most common cause, not the second.

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.

Bedbug control is most effective using Integrated Pest Management (IPM) practices, which combine multiple methods such as inspection, monitoring, heat treatments, vacuuming, and targeted pesticide use. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Bedbugs) emphasizes IPM due to bedbugs’ resistance to many pesticides and their ability to hide in cracks and crevices. Option A (programmed pesticide application) is less effective and can lead to resistance. Option C (residual insecticides) is a component of control but not the best standalone method.
