What do fumigants primarily exist as?

Fumigants primarily exist as a gas, which is essential to their function in pest control. This gaseous state allows them to disperse quickly and penetrate various materials, including soil, structures, and stored products, effectively reaching pests that may be hidden or difficult to target with other pesticide formulations.

The use of fumigants as gases means they can flow into spaces and create a uniform concentration, ensuring that pests in crevices and deeper layers are also affected. This is especially useful for applications like soil disinfestation, where the fumigant can move into the soil matrix to treat pests and pathogens.

Understanding that fumigants exist as gases highlights their unique application methods, which differentiate them from solids or liquids that may not be able to reach pests hidden within materials or soil as effectively.
