The present invention relates to a rhinitis therapeutic device including a main body and a pair of insertion rods, and provides a rhinitis thrapeutic device and a control method thereof for preventing a light source from irradiating light irrespective of a user's intention during use. A sensing light source and a light receiver are installed on inner surfaces of insertion rods of the rhinitis therapeutic device. The sensing light source emits light when power is supplied. An intensity of light of the sensing light source is preferably of a low intensity which is less likely to cause eye damage. The light from the sensing light source is detected in the light receiver, and when the rhinitis therapeutic device is inserted into the nose, the light of the sensing light source is blocked by the nasal septum. At least one therapeutic light source formed on the pair of insertion rods is controlled to emit light when the amount of light detected by the light receiver is less than or equal to a predetermined reference light amount or to emit light after power is supplied and then a predetermined reference time elapses. Thus, it is possible to reduce the possibility of eye damage by the light source of the rhinitis therapeutic device.
