Things You'll Need
Swimming pools require a lot of maintenance to keep them both looking good and safe for swimming. Insects and other creatures are often attracted to the standing water, especially if the water is not properly chlorinated. If you are noticing a large number of worms around or in your pool, take action immediately to prevent the problem from getting worse. There are also parasitic worms that are difficult to see which cause illness. Preventing all worm varieties from infesting your swimming pool requires just some basic maintenance.

Keep any soil or plants at least 20 feet away from the swimming pool. Worms normally live in dirt, and hard rain can draw them out of the ground. As they try to get out of the rain, they could end up in the pool accidentally if the dirt and plants are too close to the pool water.
Use a pool cover whenever the pool is not in use to prevent worms and other organisms from infiltrating the pool water when no one is paying attention.
Maintain the pool's chlorine level in accordance with pool instructions to help kill off parasitic worms that spread disease. Chlorine kills off microorganisms effectively, but it takes time for it to have an effect. However, parasitic worms are more likely to survive longer in nonchlorinated water than they are in a properly maintained pool.
Keep anyone who is ill out of the pool, especially children with digestive problems. Parasitic worms can spread from fecal contact with pool water, and preventing anyone with stomach pains or other digestive disturbances from swimming can go a long way toward preventing worms from spreading from one person to another.
