Re: Small Black Bettles in pool???
Hi Elsa,
Had the same problem myself in early summer in the first few weeks after filling the new pool. My chemistry was within all recommended ranges and I had the pump/filter on 12 hours a day.
A poster on this forum was writing about boatmen and backswimmers, so I asked him to describe the critters further, which he did; he was in OK and I'm in TX. Seems as if many areas of the country have these, as I believe another poster had them in IL.
Anyway, they're relatively harmless (a few do bite) and very resistant to chlorine (they laughed when I shocked the pool and invited more to the party). Best bet is to get a skimmer net and get a technique for flinging them up and out of the pool and then squashing them. Yup, if you don't, they'll crawl or fly back into the pool.
I had about 15-20 at one time. Managed to kill them all and have had only 1 or 2 since. Hopefully, it was just a seasonal thing.
