Flit gun

A "flit gun" refers to a hand-held insecticide sprayer, typically a metal pump-action device used to disperse liquid insecticide into the air. The term is somewhat dated, primarily associated with usage from the early to mid-20th century. Flit guns were commonly employed for controlling household pests like flies, mosquitoes, and other flying insects. The insecticide used in these devices was often referred to simply as "Flit," and the association with the product name led to the adoption of "flit gun" as a generic descriptor for this type of sprayer, regardless of the specific insecticide used. While these devices have largely been replaced by aerosol cans and more sophisticated spraying systems, the term "flit gun" remains recognizable, particularly among older generations, as a historical method of pest control.
