What formulation would you choose if you wanted to penetrate cracks, soil, burrows, and enclosed areas?

Selecting a fumigant is appropriate for penetrating cracks, soil, burrows, and enclosed areas due to its gaseous state. Fumigants are designed to diffuse thoroughly into spaces that are often inaccessible to solid or liquid formulations. When applied, they can fill voids and penetrated areas where pests may be hiding, allowing for effective pest control in environments that require complete or deep penetration.

In managing pests, especially in enclosed spaces or complex environments like burrows, achieving even distribution of the pesticide is critical. Fumigants can directly penetrate materials and structures that might hinder other formulations, such as aerosols or dust, from reaching their target. This makes them particularly valuable in treating infestations that are not just surface level but require addressing the challenges of enclosed or difficult-to-access areas.

Other formulations, such as aerosols and dusts, typically stay localized and may not adequately reach deeper into the structures or soil. Granules can also lack the necessary mobility in confined spaces, making fumigants the most effective choice in this context.
