Which term refers to gases which kill when they are inhaled or absorbed by the pests?

• A. Fumigants
• B. Pheromones
• C. Attractant
• D. Translocated Herbicides

Answer: (A)

Gases that kill pests when they are inhaled or absorbed are called fumigants. Fumigants are volatile, penetrating the spaces where pests hide—in cracks, soil, or packed goods—and act in the gas phase to destroy them. This makes fumigation effective for reaching hidden or enclosed pest populations that contact sprays can’t reach. Pheromones, by contrast, are chemical signals used for communication and behavior modification, not killers. Attractants lure pests but don’t kill by inhalation. Translocated herbicides are plant-directed chemicals moved within the plant to kill vegetation, not pests.
