Provided in the present invention are a powder-type insecticidal composition and a manufacturing method thereof. The manufacturing method comprises: a material preparing step of preparing 100 parts by weight of boric acid, 2-4 parts by weight of sugar based on 100 parts by weight of boric acid, 70-90 parts by weight of potato starch based on 100 parts by weight of boric acid, 1300-1700 parts by weight of sparkling water based on 100 parts by weight of boric acid, and 1300-1700 parts by weight of distilled water based on 100 parts by weight of boric acid a sugar dissolving step of manufacturing a sugar solution by adding and dissolving sugar in the sparkling water a heating step of mixing the sugar solution and the distilled water, and heating the same up to 80°C a boric acid dissolving step of manufacturing a boron solution by dissolving boric acid by adding boric acid to the heated mixed solution a cooling step of cooling the boric acid solution to 25°C a starch mixing step of manufacturing a starch mixed solution by adding the potato starch to the cooled boric acid solution and stirring the same a drying step of obtaining a solid material by pouring the starch mixed solution into a vaporization container, uniformly spreading and drying the same and a grinding step of manufacturing a powder-type insecticidal composition for cockroach by inputting the solid material into a grinder and grinding the same. According to the present invention, sugar as an attractant can uniformly bind to boric acid by binding to dissolved boric acid in a recrystallizing process in a state of maximizing the solubility of boric acid by adding boric acid to heated water in manufacturing of a powder-type insecticidal composition using boric acid, so as to uniformly bind an insecticidal component and an attracting component, thereby having excellent attracting and insect-destroying performance.COPYRIGHT KIPO 2016본 발명은 분말형 바퀴벌레 살충조성물과 그 제조 방법에 관한 것이다.본 발명의 분말형 바퀴벌레 살충조성물과 그 제조 방법은, 붕산 10
