A high temperature pest control method capable of controlling pests efficiently by high temperature treatment without using a fumigant is provided. A method for applying a heated air heated to a pest control temperature for a certain period of time to a target object C accommodated in a processing chamber 20 so as to be freely put in and out, thereby controlling the pests attached to the target object at a high temperature. The heating member 40 is installed in the discharge portion 33 of the circulation fan device 30 in which the suction portion 32 is disposed in the processing chamber so as to face the inside of the processing chamber, and the heated air is sent into the chamber through the heating member. At the same time, the air circulating in the room is introduced into the suction portion of the circulation fan device and circulated. [Selection] Figure 1【課題】薫蒸剤を使用せずに高温処理によって効率よく害虫を駆除することができる高温害虫駆除方法を提供する。【解決手段】処理室20内に出し入れ自在に収容された被処理物Cに対して、害虫駆除温度に熱せられた加熱空気を一定時間付与して被処理物に付着した害虫を高温駆除する方法において、前記処理室内に、吸い込み部32を処理室の内側方向に向けて配置した循環ファン装置30の吐き出し部33に加熱部材40を設置して前記加熱部材を介して加熱した空気を室内に送り出すとともに、室内を流通する空気を前記循環ファン装置の前記吸い込み部へ導入して循環流通させる。【選択図】図1
