Which method involves applying fogs or fine sprays to eliminate insects on contact?

The method that involves applying fogs or fine sprays to eliminate insects on contact is known as space treatment. This approach is particularly effective for managing pest populations in the airspace or areas where insects are likely to be present. Space treatment utilizes a formulation of pesticide in such a way that it disperses through the air, creating a mist or fog that can reach insects hiding in various locations, making contact more readily.

In contrast to space treatment, ground treatment typically refers to applying pesticides directly onto the soil or plant surfaces, which targets pests in those specific areas rather than in the surrounding airspace. Soil treatment focuses on applying herbicides or insecticides to the soil to affect pests residing within the soil itself or to prevent their emergence. Water treatment is not a recognized method for managing insects with pesticide contact but might refer to using water to mix with herbicides or as a vehicle for application, rather than dispersing pesticides in the air.
