Springtails love moisture, so make sure any plant areas near the pool are not over watered. I have a problem with them in the Spring when it rains and the plant bed near the rear of the pool stays in the shade. Poof.. they all come out. Our landscaper told us about "Cyfluthrin" which is very effective in killing them (in the garden/grass not pool). Bifen Granules work as well, but not available in CA where I live. Again, I don't have first hand experience using them, just what I was told by someone in the landscape business. My problem goes away in May since the plant area gets full sun all day and dries up quick.
