Design description

A Flit gun consists of a pneumatic tube with a hand-operated plunger to force air through an air nozzle in the front. Below the front of the pneumatic tube is a secondary tubular container designed to hold a liquid insecticide, this reservoir set at 90 degrees to the pneumatic tube. The insecticide reservoir traditionally has a screw-cap for pouring additional insecticide into the container, plus an internal hose that feeds from the fluid reservoir up to a tip placed just forward of the air nozzle of the pneumatic tube. This arrangement mists or atomizes the insecticide into a spray when the pneumatic tube handle is pumped, without the requirement for any compressed propellants to be stored.
