Which of the following is considered a physical pest control method?

• A. Insecticide sprays
• B. PVC strips, insectocutors, air curtains, and rat traps
• C. Baited poison stations
• D. Fogging devices

Answer: (B)

Physical pest control focuses on stopping pests with barriers, traps, and non-chemical devices rather than toxins. The items described fit this approach because they rely on physical means to prevent entry or remove pests.

PVC strips at doorways act as a continuous barrier that disrupts pest movement without spraying or poisoning. Insectocutors lure insects to a light and then trap or kill them through a non-chemical mechanism, typically using electricity or a containment grid. Air curtains create a strong, invisible barrier of moving air at entrances, making it hard for pests to pass through. Rat traps provide a mechanical method to capture or kill rodents when they attempt to move through an area.

Other options use chemicals or aerosols to control pests, which is why they’re not considered physical methods.
