What type of products are oil concentrates most commonly used in?

Oil concentrates are primarily used in fumigants due to their property of being able to dissolve active ingredients and penetrate surfaces effectively. Fumigants are gaseous pesticides that can diffuse into the air and permeate materials, which makes the inclusion of oil concentrates valuable. These products help in improving the stability and adhesion of the active ingredients within the formulation, allowing for a more effective pest control application inside structures or in soil.

In this context, while other formulations like liquid pesticides or granular insecticides are essential in pest management, they utilize different types of carriers or solvents that are better suited for their unique applications, rather than oil concentrates specifically formulated for fumigation.
