Actually it not fogs.
The environmental workers are spraying pesticide to kill the cockroaches. I always hate this day, especially when I’m on my way home. You will see numerous of cockroach’s bodies on the floor as you walk one block to another. One thing that that dread me the most is, some of the roaches are still alive and they are struggling on the floor!


Don’t you disgust cockroach?
