4. Water: Because cockroaches like moisture, they are usually selected near a water source when applying pesticides, but it should be noted that the bait is washed and soaked in water or wiped with a rag, resulting in local cockroaches having no medicine to eat and not achieving the desired effect. It is generally better to apply the pesticide after 8 p.m., and it must be after cleaning, so as not to wash the application away.
