Airofog gel dispensor is a professional and highly efficient tool for the control of crawling insects 

such as ants and cockroaches.  Unlike other dispensors, it sucks gel from the front end of the bait tube by use of negative pressure in order to get out every last drop of gel more precisely, and with a high level of control.  As a pistol, a 5-position dosing wheel fitted inside the grip。

It matches up with 30-35g industry standard gel tubes.  Two calibrations are supplied.
