Insecticide spray apparatus

An insecticide spray system for emitting a very fine mist-like spray of insecticide, comprising:

• a container for containing a supply of insecticide;
• a portable pump unit for generating a high pressure flow of gas and having a handle suitable for enabling the pump unit to be carried with one hand;
• a spray gun having an atomizing mechanism disposed within an extended nozzle for generating and directing mist-like spray, said atomizing mechanism including means forming an elongated cylindrical passageway having one end for receiving a high pressure flow of gas from said pump, and having a second end forming an exit orifice proximate the distal end of said nozzle, and an elongated tubular needle extending through said passageway and having a first end for receiving the insecticide, and a distal end extending into said exit orifice, the diameter of said needle being small compared to said orifice;
• and
• means for communicating insecticide from the container to the nozzle;
• whereby gas flowing through said orifice causes, through venturi action, said insecticide to be drawn from said container and through said needle, and to be atomized and discharged from said nozzle as a mist-like spray.
