Yesterday I hunted and smashed about 8 of these little swimming nightmares. Most of the time they were swimming directly at me as I ran away trying to find a net to capture them. I read that they usually feed on algae so I did an OCLT last night and didn't lose anything at all, so I don't think that's the problem. I also checked the ladder and scrubbed the pool (my poor arms) down really good. So assuming the problem isn't algae will they just go away on their own? Or is there something I can do to get them to avoid the pool? I live about 2 blocks away from a lake, so that may be a contributing factor. I wouldn't really care all that much, I've made peace with the tree frogs, but they bite and I often have my niece in the pool with me and don't want her getting bit. Thanks!
