It depends on what type of gnat you are seeing. Most gnats will hatch in water.
I find that the best way to rid my home of these unwanted guest to to add some drain cleaner to my sinks and tub just before we go to bed.
You will notice the flies/gnats gone in just one day as most only live one day as an adult.
Empty the garabge, keep fruit peels outside, hang sticky fly traps in the kitchen.
Keep your air conditioner working they will be sucked to the filter and may be killed on it I do it here in Bangalore.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
