油性殺蟲劑相較水性來說，殘效效果會更好，因為液態藥劑偏油，不易被戶外環境或雨水影響，因此推薦大家在室外使用，像是陽台、門外、走廊、戶外和庭院等等地方。
不同的蟲害在不同的季節有不同的活動規律。比如，蚊子一般在夏季和秋季活動頻繁，因為這兩個季節氣溫高、濕度大，適合蚊子繁殖。所以，殺蟲劑什麼時候使用，在蚊子活動高峰期，如傍晚時分，使用殺蟲劑效果會更好。蟑螂則一年四季都可能出現，但在氣溫較高的夏季和秋季，其繁殖速度會加快。因此，在這兩個季節，要加強對蟑螂的防治，定期使用殺蟲劑。
雖然說除蟲菊素對於大部分的哺乳類的毒性較低，對於貓來說卻是劇毒！因為貓體內缺少了分解除蟲菊素所必要的酵素。所以家裡如果有養貓的話在使用上要特別注意。
好，既然要學，那就要練習。但這些機器人要去哪裡獲得足夠的練習機會？總不能直接去你家廚房實習吧。答案是：它們在數位世界裡練習。
殺蟲劑是一種針對害蟲的化學武器，內含多種化學成分，能有效消滅家中的害蟲。根據其擊昏害蟲的速度，殺蟲劑可分為三種：強速效性藥劑、中度速效性藥劑以及慢效性藥劑。
長時間聞殺蟲劑氣體可能會引起頭暈、噁心、嘔吐等不適症狀，嚴重的還可能影響神經系統和呼吸系統。因此，在使用殺蟲劑時，要盡量避免長時間聞殺蟲劑氣體。如果不小心聞到了過多的殺蟲劑氣體，要立即到通風良好的地方休息，如果症狀嚴重，要及時就醫。
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？
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。
遠離火源：殺蟲劑成分屬易燃品，嚴禁對著火源或易燃處噴灑，以防引發火災。

一般常噴灑於室內的角落、門窗、紗窗、排水孔等地方。若使用有殘效功能的水性殺蟲劑，可以預防害蟲入侵家中。
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。
沸石之所以能解決這個難題，是因為它獨特的物理化學特性，能主動為塑膠餐具提供它最欠缺的「外部熱能」。整個過程分為三步：http://www.drugoffice.gov.hk/gb/unigb/www.pestcontrolcompanyhk.com/
