最有效的方式是將藥劑噴灑在門窗縫隙及窗框上。藥劑乾燥後會形成持續作用約兩週的殘效結晶，能消滅害蟲並防止牠們飛入家中。
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：
我們一路看到了機器人如何學會思考、觸摸，甚至舉一反三。但這一切，都建立在一個前提上：它們的物理形態是固定的。
一般家庭可以不用特別擦拭，殺蟲劑具有殘留效用的特性，預防害蟲的作用。
；但缺點是藥劑毒性也比較高，人與寵物都要離開，使用後也需要清潔與清洗，雖然效果最好，但要注意的會更多。
水煙式除蟲劑臭蟲使用後，許多人都會疑問是否需要洗衣服。實際上，洗不洗衣服視乎個人的偏好和蟲蟲滅蟲劑的成分。水煙式除蟲劑通常含有化學成分，這些成分可能會殘留在衣物上。
特性：揮發快、易分解、時效性短。且水性殺蟲劑對人跟寵物更安全，使用後容易清潔。
當家裡出現害蟲，像是蟑螂、蜘蛛等，大部分的人首先想到就是，使用殺蟲劑來消滅牠們。然而，除蟲劑要在何時使用最好呢？
殺蟲劑是有毒的，如果使用不當，確實可能對人體造成危害。但只要按照說明書的要求正確使用，並做好安全防護措施，如佩戴口罩、手套等，就可以將危害降到最低。在選購殺蟲劑時，殺蟲劑推薦大家選擇那些安全性高、對人體危害小的產品。
殺蟲劑成分對魚類等水生生物毒性很強，而且像貓對於除蟲菊精無法分解的問題
互動�?模組們能形成一個可隨時變形的三維曲面，即時追蹤使用者的手勢，把手的動作轉換成實體表面的起伏，等於做出了一個會「活」的觸控介面。
氣霧劑型殺蟲劑：氣霧劑型殺蟲劑使用方便，噴灑時要將噴嘴對準蟲類經常出沒的地方，如廚房的縫隙、衛生間的角落等。按下噴霧按鈕，保持一定的距離，均勻地噴灑。殺蟲劑怎麼噴，使用氣霧劑時要注意不要過度噴灑，以免造成浪費和環境污染。
若防治對象為爬行昆蟲（例如：蟑螂、螞蟻），可在發現時直接往蟑螂身上噴殺蟲劑，或者配合蟑螂夜間活動的習性，睡前「適地」於蟑螂常出沒處噴灑殺蟲劑。
將工業用大麻稱之為「明日新亮點」似乎有些奇怪，因為它被用於製作人類衣物的纖維，已長達數萬年的時間。它之所以被納入本文，不是因為它可以做什麼，而是因為它可以取代什麼。http://www.drugoffice.gov.hk/gb/unigb/www.pestcontrolcompanyhk.com/
