Which equipment is designed to discharge liquid insecticide while being worn or mounted?

The mist blower is specifically engineered to discharge liquid insecticide, and it is either worn by the operator or mounted on a vehicle. This equipment utilizes a fan to create a turbulent mist that disperses the insecticide in a fine spray over a wide area, making it especially effective for applications in areas where mosquitoes are prevalent. The design of a mist blower allows for precise application by controlling the droplet size and the distribution pattern, ensuring that the insecticide covers both the vegetation and the airspace where mosquitoes are likely to be present.

In contrast, while a spray canister is also used for applying liquid insecticides, it usually requires manual operation and does not have the same capability for wide-area coverage or wearing/mounting as a mist blower. Fogger machines, which produce a dense fog of insecticide, may be mounted but are typically used for ground or aerial applications rather than personal use. A pesticide granulator applies pesticides in granular form, which is a different method and not liquid insecticide application. Therefore, the mist blower stands out as the equipment designed specifically to discharge liquid insecticides while being worn or mounted, making it the best choice for this question.
