What does "fumigation" involve in pest control?

Fumigation is a specific pest control method that involves the utilization of gases to eliminate pests within sealed areas. This technique is effective because the gaseous pesticide penetrates all areas of a structure, including cracks and crevices where pests may hide, providing comprehensive insect control. It is particularly useful for treating large infested areas, such as warehouses or ships, and is often employed in situations where other methods may not reach all pest harborages.

The fumigation process necessitates a completely sealed environment, which allows the gas to effectively saturate the area and ensures that pests exposed to it will be eradicated. The proper application of fumigants has stringent safety protocols, as the gases can be hazardous to both humans and non-target organisms.

In contrast, the other options describe different pest control methods, such as liquid pesticide application, solid bait usage, or trapping, none of which involve the specialized use of gases and sealing critical to the fumigation process.
