如果看到蟑螂，請在牠周圍畫圈噴灑。直接對著翅膀噴效果有限，要讓藥劑沾到牠的腹部才能有效殺死牠。
驅蚊產品怎麼選？室內外驅蚊方法大公開，自製驅蚊水＋精油與盆栽天然防蚊術
，液劑長效殺蟲劑可以作為預防措施，在害蟲季節來臨前使用，減少害蟲的出現。
這些聽起來有點專業的名詞，最後都回到三個簡單問題：碗洗得乾不乾淨？能不能馬上乾爽收起來？花多少電？
可能這時候就會有疑惑，那會不會對人體造成傷害？除蟲菊精對哺乳類動物較無影響，加上一般環境用藥的成分濃度皆需符合規範，中毒機率很低。
，這種方法適合用於室內空間，如：床褥、沙發和地毯深處，對付床蟲、塵螨等等。
操縱�?五個模組組合成一條機械臂，撿起物體，甚至透過末端模組的伸縮來擴大工作範圍。
殺蟲劑水性主要是較易分解、遇水可溶解，可以針對飛蟲和爬行害蟲一起使用
適合戶外場所，例如：工廠、倉庫、戶外庭院等皆可用。能同時消滅小黑蚊、蚊子、蒼蠅、蟑螂、螞蟻、白蟻、跳蚤等七種害蟲，接觸藥劑即死亡。
，所以除非大量使用，不然市面上的除蟲產品都可以安心使用，但是在使用前後一定要注意這幾點：
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：
只要有使用殺蟲劑的正確觀念，並搭配專治的其他除蟲產品，就能有效維護居家好品質囉！
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。
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/
