This creation is a kind of spray cans for having cover, includes: a tank body has a nozzle； One cover, including a first end and a second end, there is a perforative hollow portion between the first end and the second end, the first end system actively combines the tank body, the first end is equipped with a pressing piece and corresponds to the nozzle, when the cover and the tank body relative displacement, the pressing piece is by the corresponding nozzle for triggering the tank body, to generate the hollow portion of a fluid to the cover. A pest is covered by the cover, then chemical agent is sprayed to the pest, concentrates desinsection process more, avoids the pest what from struggling and escapes, and the cover has a closely sealed portion and can more prevent user from sucking the poisonous gas being harmful to the human body.本創作係一種具罩體之噴罐，包含：一罐體，具有一噴嘴；一罩體，包括一第一端及一第二端，該第一端及該第二端之間有貫穿的一中空部，該第一端係活動地結合該罐體，該第一端設有一按壓件對應該噴嘴，當該罩體與該罐體相對位移時，該按壓件將對應觸發該罐體的噴嘴，以產生一流體至該罩體的中空部。藉由該罩體罩覆一害蟲，再對該害蟲噴灑化學藥劑，使殺蟲過程更為集中，避免該害蟲於掙扎逃逸，且該罩體具一密合部更可防止使用者吸入對人體有害之毒性氣體。
