Yes, I read about that from someone who likes sitting on the veranda with her friends. She would fill a plastic basin with water and put a few drops of dish-washing liquid in it and the leave the basin on the deck. She said that she would see mossies dive into the basin and die.
If you have pots and pans or small ponds of rainwater in your yard squirt a very small amount of any hand dishwashing liquid on them. This breaks the surface's attention of the water and mosquitos cannot land on the water to lay eggs. This trick really works and reduces mosquitos if you collect rainwater or have small ponds of water in your yard.
