When the level of chlorine is low, algae grow more easily in your pool. This is why you have to ensure that the pool is shocked repeatedly and the water is sanitized and disinfected. It’s a well-known fact that chlorination kills the organic matter, so increasing it’s level up to 2 or 3 pounds of calcium hypochlorite for every 10,000 gallons of water will surely help you get rid of water bugs. Moreover, the shock treatment must be done during night time to prevent the sun burning the chlorine.


Introducing light, you will create warmth and ultraviolet energy that will kill the water bugs more easily. Make sure that all the lights surrounding your pool are turned off and attract them by placing a direct lightning around 30 feet away from the pool. The bugs will come to the lightning and they will be killed by the ultraviolet energy.

This is a very simple and cheap treatment. In order to survive, water bugs have to come to the surface of the water and breathe air. Therefore, add 2 or 3 teaspoons of liquid dish soap into a spray bottle and search an area where they group. Spray the solution in that perimeter and you will create a protective barrier that the bugs cannot penetrate, so they will drown. Wait a few hours and then scoop them up.
