Killing pest is simple but leaving no harmful residue is difficult. Even Permetrin (artificial chrysanthemum) is UV degradable, yet still harmful to cat and aquarium.

很久以前屋企人得到d 專業 pest control 公司用品，噴後小強不特走出嚟見光至死，至少半年都唔再見隻

放入大膠袋丶再放入蟲蟲炸彈丶焗一日丶什麼都死

試咗1:99未？如果再加濃度，一般嚟講，有効幾年。

This is 99% IPA, good for electronics. $40 for 500cc bottle but very few chemical stores now, the nearest one is on Wing lok st. Sheungwan. Haven't been there for a decade so bought 2 packs of silica gel as well. Many girls were there to select aroma. Surprised?

驅曱甴，試吓放蒜頭入去。

食蟻獸未必食小強。

「如果屋企有昆蟲，點叫佢地唔好入去邊度邊度？」

畫幅圖畫係張紙兼寫埋： 內有惡食蟻獸

如果屋企有昆蟲，點叫佢地唔好入去邊度邊度？

#1.
點解我要洗? 因為兩個月前發現入面住左好多昆虫 總之好得人驚.


＞＞＞＞重點係家居曰常衞生，有人住的居所，一般唔應該有大小强，

除非？潮濕及有承餘食物，垃圾包每晚掉出門外垃圾筒前，定必要

摺好袋口。

要防止佢再住入去，係要全屋搞滅蟲

以前有隻巴斯夫殺曱甴藥，一隻曱甴食咗，全屋曱甴冚家拎

如果吸塵機即使清走晒啲塵埃裏面仍然有異味，咁就難攪啲。Ozone 都可以考慮嘅。以前有啲人買賣二手煙斗，就係用ozone 除臭，用咗之後啲二手煙斗真係冇晒味。但係佢哋唔係用UVC，係用Ozone generator

擠個喇叭仔入去，耐5耐焚吓，震碎曬蟲蟻經胍

我無理解錯嘅話，McDull兄唔係要殺菌消毒，係想防止小強再走入去住。

I did work in the largest ozonation plant in the territory. Each unit was size of a single decker bus. Lightning in a bottle, using glass tube as dielectric with cooling water jacket since reaction is exothermic. Would need cleaning due to formation of nitric acid from concentrated air. Using LOX, liquid oxygen is much clean but expensive.

People commenting on ozone simply made me laugh.

uv 捧一定冇用?(估您寫錯字)
臭氧沒有研究，但估空間(空氣流動)有所影響。因為家中有老狗，近3年我常用 細細個uv口罩口消毒，托賴佢重ok。
想買呢枝1秒殺。

買呢支試吓啦

uv 捧一定冇用, 但 uv既副產品臭氧我仲諗緊.
主要係有養貓, 好多 option都唔用得

對某昆虫來講，多數物品都係冇用。。

買枝uv電棒消毒殺菌，乾洗之。

Appliance would die upon cleaning with water and dried. Tried before, cleaning tv CON board with 70% alcohol and smoke coming out. Should use 99% isopropyl alcohol for electronic work, available from chemical store.

Pure electrical item, can survive. Electrical water heater flooded with water and dried. But must conduct 500V insulation test before using. Large industrial motor being steamed in workshop and then dried in oven, standard procedure.
