The purpose of the present invention is to provide a heat evaporation type tool for insect pest control wherein, in the case of using a heating element such as a disposable body warmer, said heating element being packed together with a controlling agent-containing member when not in use, for example, during storage, the controlling agent can be prevented from migrating into the heating element. To achieve the purpose, provided are: a heat evaporation type tool for insect pest control provided with a controlling agent-holding part 1 which holds a volatile agent for insect pest control, a housing part 2 which houses the controlling agent-holding part 1 and from which the controlling agent can be released, and a heating part 3 which is fixed to at least one side face of the housing part 2 and carries a heat-generating composition 31 enclosed therein, said heat-generating composition generating heat upon exposure to oxygen； and a heat evaporation type tool for insect pest control wherein, in the housing part 2, ventilation hole(s) 211, said venting hole(s) communicating the inside and the outside, are formed on a face of the housing part 2 opposite, relative to the controlling agent-holding part 1, to the side face thereof fixed to the heating part 3 and/or on the same face of the housing part 2 as the side face thereof fixed to the heating part 3.本發明係以提供一種使用如所謂拋棄式暖暖包等的發熱體時，即使在保存等不使用時與含有藥劑之構件及發熱體共同密封，也可防止藥劑轉移至發熱體的加熱蒸散型害蟲防除具為目的。解決手段為，可藉由一種加熱蒸散型害蟲防除具來解決，其係具備：藥劑保持部(1)，係保持具有揮發性且可防除害蟲的藥劑；容納部(2)，係封入有藥劑保持部(1)，且可放出藥劑；及發熱部(3)，係與容納部(2)的至少一側面固定，內含藉由氧氣發熱的發熱組成物(31)；甚而，可藉由一種加熱蒸散型害蟲防除具來解決，其中容納部(2)係在固定於發熱部(3)之容納部(2)的一側面之與藥劑保持部(1)相反之一側的面、或、與固定於發熱部(3)之容納部(2)的一側面同一面的至少一者具有連通內外的通氣孔(211)。
