Are tiny red worms in a pool dangerous to humans?

No, the tiny red worms found in swimming pools are not dangerous to humans. These worms are often referred to as bloodworms or gnat larvae and are common in outdoor pools. They feed on organic matter, such as algae and dead leaves, and do not pose any health risks. However, if the worms become too numerous, they can be a nuisance and can clog pool filters and pumps.
