Unverified物理杀虫粉见效慢（跳蚤/蟑螂需接触后24-72小时脱水死亡），追求立即除虫效果的场景不该只依赖硅藻土，应配合化学快杀或粘捕手段80% similarUnverified硅藻土靠物理刺穿虫体外骨骼脱水杀虫，对成虫和幼虫有效但对虫卵几乎无效，需在跳蚤生命周期内（每7天一次，连续3-4周）重复施用才能打断卵-幼虫循环79% similarUnverified硅藻土类物理驱虫粉仅对已接触的成虫(跳蚤、螨虫)脱水致死，对虫卵和体内寄生虫无效，跳蚤生命周期约3周需连续处理21天以上才能断代79% similarUnverified灭蟑螂/蚂蚁应选含拟除虫菊酯类(氯氰菊酯、高效氯氟氰菊酯)且带滞留触杀效果的产品，持效期可达30天以上，而单纯气雾型只能击倒不能断绝虫源79% similarUnverified硅藻土通过物理磨损虫体外骨骼致其脱水死亡，虫类不会产生抗药性，适合需长期反复处理的重度虫害环境78% similar
