A system for treating an enclosed area may include a plurality of fogging devices each including a housing, a fluid reservoir, a compressor coupled to the fluid reservoir, an atomizing nozzle in fluid communication with the fluid reservoir, a first wireless transceiver, and a first processor coupled to the compressor and the wireless transceiver. A wireless communications device may include a second wireless transceiver and a second processor to identify the fogging devices within the enclosed area based upon the first and second wireless transceivers, determine respective fogging times for the fogging devices based upon a size of the enclosed area and a number of the foggers identified within the enclosed area, and initiate a treatment cycle during which, on a coordinated schedule, the first processor of each fogging device causes its associated compressor to dispense fluid into the enclosed area via the atomizing nozzle for the respective fogging time.
