A system for remotely indicating the level of grain being loaded into a grain trailer. Information relating to each user interface window existing within a computer operating system is stored in a working database that is different from real-time user interface window information maintained by the computer operating system. A cross sectional area of the small diameter plug is made larger than a cross sectional area and a diameter of a connection plug, and is made smaller than a cross sectional area and a diameter of the large diameter plug. Thus, the automated pest control dust applicator device includes: an elongated support pole having a predetermined length and having a distal end and a proximal end; a dust dispensing nozzle located proximate the distal end of the pole, and connected to a dust reservoir; a conduit and a compressor, with appropriate controls.
