hello!

If the pesticide is sprayed uniformly by the epidemic prevention station, mosquitoes and flies will fly into the house and die within one month after spraying. And it is harmless to the human body. Some people drive away flies by some indigenous methods, and close the backyard doors and windows of restaurants with dense nets ... There are also some irresponsible bosses who burn a red iron plate in the restaurant every night and pour Didi Wei (pesticide) on it to smoke flies. Although it is not good to do so, flies will die.

if you have any questions, please ask.
