Commodity Fumigation License Practice Exam

Is it true that fumigation is the only pesticide form that can penetrate hollow blocks or bricks?

1. True

2. False

3. Only for certain types of insecticides

4. Depends on the formulation used

The correct answer is: True

Fumigation is indeed the only pesticide method that can effectively penetrate hollow blocks or bricks due to its gaseous state. This unique characteristic allows fumigants to seep into cracks, crevices, and any voids within structures that liquid or solid pesticide forms cannot reach. The gas can travel through porous materials and effectively control pests that may be hiding within these spaces, ensuring a comprehensive treatment. Other pesticide forms, such as sprays or dusts, typically do not have the ability to permeate these barriers and may only target surface infestations, leaving protected pests unaffected. Thus, the assertion that fumigation is the only method capable of penetrating these materials stands true in the context of pest control.
