Why is the smoke of property anti-virus so big?

The reason why the anti-virus smoke in the property is so big is that the anti-virus agent used produces thick smoke. Professional pesticides or disinfectants are generally used in property disinfection, and these chemicals will be sprayed or released in the form of smoke. The purpose of smoke is to cover every corner of the room evenly with pesticides or disinfectants in order to kill bacteria or pests. Due to the high concentration of disinfectant used in the property, or the large smoke caused by spraying methods and equipment, the smoke is large. The purpose of this is to ensure that pesticides or disinfectants can cover a wider range and improve the killing effect.
