竟然係咁，真係唔講唔知

我明白你有幾恐懼.
搵千赤士 chinchex 網頁, 佢有教的.
其實千赤士係沒藥性, 原理是同使用DE粉一樣,木蝨沾到粉末令到木蝨身體裂開, 脫水而死.
不過DE粉要2-3星期才有明顯效果, 千赤士就快好多1-2日就有明顯效果.
雖然沒藥性, 但粉末很輕，會飄浮在空氣中, 吸入也會不好, 所以要帶口罩才塗抹.
如果床褥也被入侵, 可用防蝨床套套住床褥, 木蝨便會進不入床褥也走出不來, 在床褥內的木蝨經過一段時間沒血吸會自然死亡.
如果木蝨擴散到不可收拾, 可以搵熱能滅蝨,不過好貴.

建議網上爬多D文搵方法. 希望以上可以幫到你.

(S)-METHOPRENE

(S)-Methoprene is an insect growth regulator, or more precisely, a juvenile hormone mimic. Rather than killing insects, it controls them by interfering with normal hormone levels within the insect at critical development periods preventing growth and/or maturation. It is active by contact or ingestion and in some insects (e.g., fleas) it affects eggs or female fecundity. (S)-Methoprene controls a broad range of insects including diptera, hymenoptera, coleoptera, homoptera and syphonaptera. Use patterns include post-harvest grain protection, mosquito larvae control, as a preventative of flea-egg development and as a feed-through for the control of horn fly larvae in cattle manure. In the U.S., (S)-methoprene has been exempted from food tolerances by the EPA.
