An aerosol is a specific type of pesticide formulation that consists of fine particles or droplets suspended in a gas, typically using a propellant. This formulation allows for easy application over a wide area and can effectively target pests in difficult-to-reach places. Aerosols are particularly useful for indoor pest control and for applying pesticides to surfaces where precise delivery is necessary.

In contrast, dust formulations consist of solid particles and are typically used for treating cracks, crevices, and surfaces where pests may reside. Concentrates are liquid formulations that require dilution before application, often providing a higher concentration of active ingredients. Baits are solid or liquid formulations designed to attract pests to consume the pesticide, which then kills them. Each of these formulations serves different purposes and application methods, but it is the aerosol that specifically refers to the pressurized form suitable for spraying.
