Abstract: A fan assembly includes a column arranged substantially vertically, and a base, the column is connected to the base to be supported and restrained in its vertical orientation. An arm has a base end connected to the column and extends from the base end horizontally to a distal end. A fan adapter plate is connected to the distal end and has a fastener hole pattern compatible with commercially available overhead fans. A weather shield can be carried by the arm and is adapted to protect a motor of the overhead fan. Alternate embodiments include a permanently attached column/base embodiment, a portable, self standing column/base embodiment, a clamp base embodiment for clamping the base to a deck, weighted base embodiments, and a horizontal wall-mounted fixture. A method of abating mosquitoes includes the use of the overhead fan in an outdoor environment.
