Which formulation type is typically found in liquid form and designed for immediate application?

The formulation type that is typically found in liquid form and designed for immediate application is the aerosol. Aerosols contain the active ingredient in a liquid form that is pressurized and dispersed as a fine mist when the can is activated. This allows for quick and convenient application, making them ideal for immediate use in various pest control scenarios.

Aerosols are often used for applications that require precise targeting or quick coverage, like treating insects in hard-to-reach areas. The formulation is designed to evaporate quickly after application, which further facilitates immediate action against pests.

In contrast, emulsifiable concentrates, while they are also liquid formulations, typically require dilution with water before application. Dust and pellets, on the other hand, are solid formulations, which are not usually in liquid form and may require additional steps for application.
