A fan type noxious insect control apparatus is disclosed which is desirably used carried on a user's body part and excels in noxious insect control performance. To this end, the apparatus is so configured that air is drawn through an inlet port (6) by driving of an axial flow fan (3) and passed through a chemical carrier (2) carrying a noxious insect control active ingredient to form the air containing such active ingredient, the air being run out through an outlet port (7) to diffuse the active ingredient into the ambient atmosphere and further that the inlet port (6) at an upstream of the fan (3) is open facing axially thereof, the outlet port (7) at a downstream of the fan (3) is open facing radially thereof, and there are provided an annular wall (8) surrounding the fan (3) and an air flow passage (9) communicating between a delivery section of the fan (3) and the outlet port (7) to convert air flowing out of the axial flow fan (3) axially thereof to air flowing radially thereof.
