Which equipment would NOT be used for mosquito control?

The choice of a dust applicator as not being useful for mosquito control is based on the characteristics and behavior of mosquitoes. Mosquitoes primarily inhabit areas with standing water where they breed, and they are generally targeted through methods that can cover larger areas effectively.

Foggers, backpack sprayers, and granular applicators are designed to deliver pesticides in forms and volume that can effectively reach mosquitoes in their habitats. Foggers create a mist that allows for widespread dispersal of insecticide, making it suitable for treating large outdoor areas. Backpack sprayers enable targeted application in more dense vegetation or hard-to-reach areas. Granular applicators are effective for distributing larvicides in areas where mosquitoes breed, such as stagnant water.

In contrast, a dust applicator is typically more suited for insect control in enclosed spaces or for targeting certain pests that may be present in localized areas. Dust formulations may not adequately cover the larger environments where mosquitoes are found and may not deliver the necessary pesticide concentration to effectively control these insects in their breeding grounds. Thus, the use of a dust applicator is not considered appropriate for mosquito control in general.
