1. A method for controlling cockroaches, which comprises substantially airtightly forming a closed space where cockroach feces lie scattered, introducing ozone into the closed space to expose the cockroach feces present in the closed space to ozone at a concentration of 0.5 ppm to 20 ppm, continuing the exposure to ozone for a period of time of about several ten minutes up to about 8 hours so as to cause the cockroaches present in the closed space during treatment to die and to denature an aggregation pheromone contained in the cockroach feces so as to form a roach-repellent substance.
2. The method according to claim 1, wherein at least one ultraviolet lamp or ozonizer is disposed in the closed space and continuously operated to produce ozone in the closed space.
3. The method according to claim 1, wherein ultrasonic vibration is applied to the cockroach feces being exposed to ozone to improve denaturing efficiency to the roach-repellent substance.
4. The method according to claim 1, wherein ozone is produced in an atmosphere of high-concentrated oxygen to improve denaturing efficiency to the roach-repellent substance.
怎么才能清干净墙壁地毯，给下一位有婴儿的住客？
注意必须在无人的时候用。臭氧对人体有害。
原理是臭氧里面的第三个氧气分子可以和其他有机物结合，从而改变散发气味的源头分子。
不过我个人觉得需要先把地毯除掉后，用臭氧熏一下，再铺新地毯。
类似的味道。很奇怪的丑闻。那个OZONE对所有气味都有用嘛？
