The purpose of the present invention is to provide an insect pest-controlling tool which is capable of suppressing the transpiration of an insecticide contained in an insecticide-holding member, said transpiration of the insecticide being caused by unnecessary heat generation by a heat source when used either indoor or outdoor within a short period of time, which is repeatedly usable and which is capable of transpiring the insecticide while preventing the insecticide-holding member from being taken out by babies or infants. To achieve this purpose, provided is a heat evaporation type insect pest-controlling tool comprising a container (1), a heat source (2) that is housed in the container (1) and provided with a heating element (21) generating heat when exposed to oxygen, and an insecticide-holding part (3) that is formed on the outer surface of the heat source (2) and contains an insecticide, wherein the container (1) is provided with ventilation holes (111) communicating the inside and outside of the container (1) and a lid (12) capable of freely opening and closing the ventilation holes (111).本發明提供一種即使在屋外或屋內僅短時間使用時,仍可抑制必要以上之熱源發熱,抑制保持藥劑之構件中所含藥劑揮散,可不僅使用1次而可使用複數次,另外,即使嬰幼兒無法取出保持藥劑之構件下仍可使藥劑揮散之害蟲驅除具。解決手段係藉由害蟲驅除具而解決,該驅除具具備:收容容器(1);收納於收容容器(1)之內部且具有藉由氧而發熱之發熱體(21)之熱源(2);與設置於熱源(2)之外表面之具有害蟲驅除劑之藥劑保持部(3),且收容容器(1)具備連通收容容器(1)之內外之通氣孔(111)、與自由開閉通氣孔(111)之蓋部(12)。1‧‧‧收容容器11‧‧‧蓋住開口之構件111‧‧‧通氣孔12‧‧‧蓋部
