It is almost time to enjoy your pool, so here is something I have learned through lengthy research. I had water bugs in my pool and did not know how to get rid of them. I learned that if you spray them with dish washing liquid and water from a spray bottle when they surface they will die in minutes. Use an old spray bottle that preferably has a stream and spray setting. Put a table spoon of dish washing liquid in the bottle and fill with tap water. This also works with wasps, yellow jackets and bees that land on the surface of the water for a drink. Use the stream option and shoot them. The dish washing liquid coats them and the surface of the water. They are unable to breath and will die in a few minutes.
Keep the spray bottle handy by your pool all season long. It’s actually fun shooting them. Your speed and accuracy will improve with use.
