A flea fogger is essentially another name for a fumigation device. It releases a massive amount of insecticide into a room that saturates the air completely. By this action, virtually every nook, cranny and crevice becomes inundated with pesticide particles, turning the entire fogged area into a toxic unlivable space.
In general terms, using a flea fogger should really only be applied as a last ditch method when flea infestation is so severe that other methods of control don't work. Extreme caution must be used when fogging, such as, all pilot lights and open flames must be extinguished, the entire room and/or household must be evacuated for up to 4 hours, and the entire premises must be aired out after returning.
All flea foggers on this list will be effective, when used according to their label directions. Price will be no object, since effectiveness is the prime reason for using one, and the best flea fogger will work be effective immediately and have strong residual results to keep on killing long after the fogger has been employed.
