不過即便如此，若於短時間內皮膚接觸到高濃度的除蟲菊素或類除蟲菊素，可能會有癢、灼熱或刺痛感，若是短時間內吸入或攝入高濃度的除蟲菊素或類除蟲菊素，可能會產生頭暈、頭痛、甚至意識喪失等症狀，因此大家在使用環境用藥時還是要注意劑量與保持通風喔。
根據政府環境部資訊，殺蟲劑建議依照防治昆蟲不同，實施對應的「適時、適地、適量」正確噴灑方式：
市面上的殺蟲�?除蟲劑品牌、種類五花八門，到底各個款式之間有何差異，又該如何正確選擇呢？
為確保能完全消滅蝨蟲，除了藥量要夠，還要密封屋內。密封也有技巧，並非只是關上門窗就算得上密封，所有有空氣流動的地方也需密封。因為只要有一兩個地方能產生氣流，就會沖散帶有藥性的煙霧，使煙霧不能覆蓋全部地方。
低熱容量材料（如塑膠）： 因為密度低、質量輕（m值極小），即使和陶瓷有著差不多的比熱（S值），它們能儲存的總熱能（H值）依然非常少。熱水一停，表面溫度就迅速下降，完全沒有足夠的「餘溫」去蒸發身上的水珠。
想像一個地震後的救援場景：救援隊帶來的不是一台笨重的挖土機，而是一群這樣的模組。它們首先組合成一條長長的「蛇」形機器人，鑽入瓦礫縫隙；一旦進入開闊地後，再重組成一隻多足的「蜘蛛」，以便在不平的地面上穩定行走；發現受困者時，一部分模組分離出來形成「支架」撐住搖搖欲墜的橫樑，另一部分則組合成「夾爪」遞送飲水。這就是以任務為導向的自我演化。
使用洗碗機最讓人無奈的情境，莫過於滿心期待地打開，卻發現放在角落的那幾個碗盤，上面還掛著惱人的飯粒或醬漬。明明放在中間的餐具都潔淨如新，為何洗碗機的邊緣角落總是成為水流的法外之地？
第二位，是靈巧的助手「皮諾可」： 殺蟲 它負責接收黑傑克的語言指令，並將這些抽象的命令，轉化為機器手臂毫釐不差的精準運動軌跡 。
奇葩寵物飼養日常 ：“我的螳螂今天又越獄了，現在正在窗簾上假裝是一片葉子……”
粉劑殺蟲劑的藥效持續時間最長，建議使用在大面積的地方，像是倉庫、廠房，或是房屋的縫隙角落處、門窗附近等。
殺蟲劑水性油性的主要分別，是呈現的液體質地為油性或水性。以下分別說明殺蟲劑油性水性之間的差異：
硬核科普+冷知�?：比如“蟑螂其實會游泳？”“為什麼蚊子總咬你不咬別人？”
不管是哪一種殺蟲劑，只要正確使用，而非大面積胡亂使用，都是種除蟲預防害蟲的好方法。
噴灑殺蟲劑時，要確保噴灑範圍覆蓋到蟲類可能出沒的所有地方。除了廚房、衛生間等重點區域外，還要注意廁所的縫隙、門窗的縫隙等。噴灑角度也很重要，要從不同的角度進行噴灑，使殺蟲劑能夠進入縫隙和角落，殺滅隱蔽處的蟲類。殺蟲劑怎麼噴，合理的噴灑範圍和角度能提高殺蟲效果。http://www.drugoffice.gov.hk/gb/unigb/www.pestcontrolcompanyhk.com/
