Abstract
Abstract A gas or liquid distribution system in a building for pest control in the building has a plurality of flexible tubes in the walls of the building. Each tube has a plurality of openings unevenly spaced along the side thereof along one end portion of the tube. Each tube passes through a predetermined zone in the building and has a portion without any openings extending back to a control distribution box attached to the side of the building. A panel inside the control distribution box has a plurality of openings passing therethrough and has the open end of each flexible tube attached through an opening in the panel using a special pipe end connector for connecting the tube to the panel. The pipe end connectors are color coded to indicate the amount of pesticide liquid needed to be distributed to the building zone for the particular tube. In addition, the panel has a coding system to indicate which pipe inlet is for which building zone. The control distribution box may be mounted to the side wall of the building with all the tubes passing through a pipe into the building attic with each tube passing through the wall header into a section of the building wall.
