殺蟲劑分成噴霧型、粉劑、水煙、油劑等不同類型，通常會根據昆蟲的習性來選擇：
不論是油性水性殺蟲劑，都必須正確使用才能達到最好的效果，如果心急拿著殺蟲劑亂噴一通，可能還會造成反效果。此外，針對飛行或爬行的害蟲，其使用方式也不盡相同，以下分別說明：
殺蟲劑要存放在陰涼、乾燥、通風的地方，遠離火源和熱源。避免陽光直射，以免殺蟲劑變質或發生爆炸。同時，要將殺蟲劑放在兒童接觸不到的地方，防止兒童誤食或誤用。殺蟲劑注意事項，正確的存放方式能保證殺蟲劑的質量和安全。

此外，除蟲藥劑還有另一種常見成分是「有機磷化合物」，常用於農業用殺蟲劑及環境用藥，使用後會使神經傳導異常，
一般的環境用藥，研發時通常會考量到只針對目標的生物產生作用。以殺蟲劑來說，除蟲菊素的毒性足以殺死節肢動物，
科學家透過精密的粒子追蹤實驗，給出了一個物理限制：洗碗機噴射臂的水柱，其實都是「直線前進」的。換句話說，水本身不會自動轉彎，這讓「零死角沖洗」變成了一道難解的幾何學考題。

殺蟲劑噴到蟑螂後，蟑螂死亡的時間因殺蟲劑的類型和蟑螂的個體差異而異。一般來說，擬除蟲菊酯類殺蟲劑能快速使蟑螂麻痹，蟑螂可能在幾分鐘到幾十分鐘內死亡。但有些蟑螂可能對殺蟲劑有一定的抵抗力，死亡的時間會更長一些。如果使用蟑螂膠餌，蟑螂食用後回到巢穴死亡，這個時間可能需要幾天。
水性殺蟲劑使用後大都不需要特別清潔，殘留的藥劑有預防作用，建議噴灑完一段時間後可開窗通風。如果家中有寵物或小孩，或殺蟲劑噴灑到餐具、餐桌，建議擦拭以避免誤食和污染。
在一些特殊環境下，使用殺蟲劑的時間也有講究。比如，在廚房使用殺蟲劑時，最好在廚房無人使用且通風良好的情況下進行，如晚上睡覺前。因為廚房有食物，如果在使用殺蟲劑時有人在場，可能會吸入殺蟲劑氣體，對人體健康造成影響。在辦公室使用殺蟲劑時，可以選擇在下班後，確保辦公室無人，避免殺蟲劑對員工造成危害。殺蟲劑什麼時候使用，在特殊環境下要充分考慮人員安全。
有殘效功能的水性殺蟲劑，可以預防害蟲爬進來，因當牠接觸藥劑就會死亡。
；而油性殺蟲劑以油性基質為主，比較不合適使用在飛蟲或在天花板上的害蟲，但同時因為附著力強且殘留效果好，更適合在戶外使用。http://www.drugoffice.gov.hk/gb/unigb/www.pestcontrolcompanyhk.com/
