The invention is mainly composed of a frame, a reflecting plate and at least one heat radiating tube, wherein at least one heat radiating tube is capable of generating infrared light and radiating heat to the building material, and is combined with the reflecting surface of the reflecting plate to radiate heat to the light. Reflecting to building materials, improving the heating effect of building materials, compared with the prior art, the new model does not use any chemical pesticides, is harmless to the human body, safe, healthy and environmentally friendly, greatly reduces environmental pollution and reduces the purchase of insecticides and drilling holes in the home environment. In addition to cost, it can even prevent the building materials from getting wet, thus avoiding the building materials becoming a hotbed of pests and eggs, keeping the building materials dry, greatly preventing the future invasion of insects, and effectively eradicating pests and eggs.本新型主要是由一框架、一反射板、及至少一熱幅射管所組成,其中至少一熱幅射管能夠產生紅外線之光輻射熱投射至建材,並且搭配反射板的反射面加以對光輻射熱反射至建材,提升建材加溫效果,相較於先前技術,本新型不使用任何化學農藥,對人體無害,安全、健康且環保,大幅減少環境污染並減少購買除蟲劑與居家環境鑽洞的成本外,甚至能夠大大防止建材受潮,進而避免建材成為害蟲與蟲卵的溫床,讓建材保持乾燥狀態,大大預防日後蟲蟻再度入侵的目的,並且有效根除害蟲與蟲卵等的危害。
