I was cleaning from inside the pool tonight (the best place to be when its 95deg at 8pm) and I spyed a large Water Boatman (thumbnail sized!) shoot to the top of the water near the steps - YIKES, a bug! Our first of the year. I went in that direction and that dirty little sucker shot sideways right AT ME. I looked and looked for it thinking it stuck to the pool vac hose I was holding. Then I felt a pinch OWEEE! I lifted the edge of my tankini suit and there it was just above my navel and it bit me again!! OWEE! I grabbed it off and pinched it back. But then I was disgusted because I had just seen another one swim in my direction from the steps when I was cleaning there underwater. I dumped a whole 1/2 gal of bleach at my steps and scrubed under them, almost scared of what was going to come out at me. My FC was up there at 3ppm before the bleach dump but maybe the really warm water made them too comfortable? There is no algae blooms anywhere, even under or behind the steps but I like to bleach and clean back there just in case, especially when the water temps get that high (92F)
I did not know that they bite and HARD. It left a good sized red welt from the second bite and a smaller bite next to it from the first one. When I rinsed in the shower I found another smaller one on my shoulder behind the strap - no bite there but I'm guessing it got there when I was back of the steps? Yuck and Yikes.
