I'm good at catching them alive and have a technique. Killing them is not fun and challenging, even though catching has become also very easy.
You have to put your palm in front of the fly and slowly move the palm towards her. When you are close, like you need maybe few centimeters to close your hand around her, you just sweep very fast forward and close the palm. Fly always fly forward so basicaly it will fly into your palm when you start to move it towards her.
After that it is all about your creativity
Wow! I didn’t know that. The most annoying experience for me is to see these flies flying around specially when I am eating and I would try to catch it or hit it with something. I don’t know for whatever reason that I cannot even hit or I’m missing it all the time. What is it, they’re too fast or I am too slow?
It is so irritating and they don’t make me itch but they do make me irritated and my last resort is to take an anti-bug spray and finish them.
