Which statement is true about fumigants?

Fumigants are designed to penetrate structures and quickly eliminate a wide range of pests, making them a highly effective method for controlling infestations. These gaseous pesticides disperse evenly throughout the treatment area, allowing for comprehensive coverage that targets pests hidden in various locations, including cracks and crevices. The quick action of fumigants helps to eradicate not only the adult pests but also their larvae and eggs, thus breaking the lifecycle and preventing future infestations.

The other statements do not accurately reflect the characteristics and effectiveness of fumigants. For example, while some pesticides may be slow acting or have difficulty in application, fumigants are specifically formulated to provide rapid results. Additionally, fumigants are not limited to specific types of pests, as they can target a broad spectrum of wood-destroying organisms. Lastly, fumigants are effective in large structures when properly applied, as they can infiltrate every part of the building, ensuring comprehensive pest control in extensive areas. This broad action makes fumigants a crucial tool in managing wood-destroying pests.
