Be back in half an hour. At this time, mosquitoes are either smoked to death or fainted. At this time, they can be easily eliminated. Then open the window (close the screen window) for ventilation. People can dry orange peel and orange peel, wrap them in stockings and put them in the corner. The smell can not only prevent mosquitoes, but also freshen the air.
