The present invention relates to an insecticidal composition for disinfecting a cattle shed and a poultry farm, and a preparation method therefor, and more specifically, to an insecticidal composition comprising 0.1-30 parts by weight of formic acid and 0.1-20 parts by weight of an active ingredient (acaricide) for exterminating ticks. The insecticidal composition of the present invention has an immediate acaricidal effect on chicken mites (mites, red mites) within 24 hours and shows a sustained acaricidal effect for at least one month. Accordingly, when the insecticidal composition is periodically used, it is possible to reduce the stress on domestic animals and to block the infection of other chicken mite-mediated pathogenic organisms by decreasing the dispersion of chicken mites.La présente invention concerne une composition insecticide pour désinfecter un abri pour bétail et une ferme avicole, et un procédé de préparation de celle-ci, et particulièrement, une composition insecticide comprenant 0,1-30 parties en poids dacide formique et 0,1-20 parties en poids dun ingrédient actif (acaricide) pour exterminer les tiques. La composition insecticide de la présente invention a un effet acaricide immédiat sur les dermanysses des volailles (mites, poux rouges) dans les 24 heures et montre un effet acaricide prolongé pendant au moins un mois. Par conséquent, quand la composition insecticide est utilisée périodiquement, il est possible de réduire le stress sur les animaux domestiques et de bloquer linfection dautres organismes pathogènes médiés par le dermanysse des volailles en diminuant la dispersion des dermanysses des volailles.본 발명은 축사 및 양계 소독용 살충제 조성물 및 이의 제조방법에 관한 것으로서 좀더 자세하게는, 개미산 0.1 내지 30중량부 및 진드기 구충용 활성성분(acaricide) 0.1 내지 20 중량부를 포함하는 살충제 조성물에 관한 것이다. 본 발명에 의한 살충제 조성물은 닭 진드기(응애, 닭 와구모)에 24시간 내 즉효성 살비 효과를 가지며 1달 이상 지속적인 살비 효과를 나타내므로 주기적으로 사용할 경우, 닭 진드기의 분포를 감소시켜 가축의 스트레스를 감소시키고 닭 진드기에 의해 매개되는 타 병원체의 감염을 차단할 수 있다.
