In the past, we have sprinkled the perimeter of the pool with Sevin dust ...deters (and kills)alot of little bugs and stuff. We also sprinkle the perimeter of our home(foundation) to keep the bugs out. Sevin is not harmful to our 4 legged children, we don't have 2 legged children so I don't know about using it around them.

This year I think we will also try the DE since we will have plenty, the smallest bag I can find is 20lbs and at 1 cup in skimmer rate it will take a while to get rid of it!!!
