Ants and Flies

Two types of ants are appearing out of nowhere in our house. One is the tiny red colour one and the other is the larger one. Whenever there is food, the ants will apparate around it!

We read from forums that this Combat Ant Killer is good. I will report the result in one week's time. 

Another tougher issue is the shit fly (or you called it fruit fly). They always gather around the sink and whenever I turned on the tap, they will suddenly fly around the sinks. 


We tried the vinegar+soap booby trap (from the Internet) but it didn't work.
