We have a above ground pool. We also have a field behind our property and they plowed it last Sunday. After 12 years of this same field being plowed we have neer had this experience. While floating on a blue raft in the pool Sunday afternoon I felt like something was biting me but I could not see anything in the water. I got out of the pool and looked on the blue raft and there were little tiny yellow, orange and some black bugs. They crawl, hop and seem to fly. They also bite or sting. They are so tiny, its really hard to see them. I have double shocked the pool and also got Bug-Out from the pool store. They are puzzeled and so are we. I am letting the pump run 24 hours a day and still as of today I have these in my pool and they are still alive. I have vaccumned twice and the water looks fine. All test for chemicals are fine. Does anyone have any suggestions. I don't think draining the pool and re filling it would work due to I think they are in the air. I sprayed home defence around the grassy area of the pool two days ago. They are still there. PLEASE SOMEONE HELP ME!!!!
