As summer approaches and the temperature rises, swimming pools become the choice of recreation for many families. However, amidst the fun and excitement, there’s an underlying concern for many – can chlorine kill lice? And can one contract lice from swimming pools? This guide aims to answer these queries and more, providing clarity on this rather confusing topic.

The Lice Dilemma

Before we delve into whether chlorine can eliminate lice, it’s essential to understand the nature of these pesky parasites. Lice are tiny insects that infest the human scalp, causing severe itchiness and discomfort. They are particularly common among school-age children, given their propensity for close contact during play.

Head lice are hardy creatures and have developed resistance to numerous chemicals. They firmly latch onto human hair, making it difficult to dislodge them even in water. Understanding their resilience is crucial in answering the question, “does chlorine kill lice?”

Chlorine Vs. Lice: An Unlikely Battle

In an attempt to rid themselves or their children of lice, many parents may consider turning to chlorinated swimming pools. After all, chlorine is a potent chemical known for its disinfectant properties. However, the question remains, does chlorinated pool water kill lice?

Unfortunately, the answer is no. Lice are incredibly resilient. Studies have shown that even after being submerged in chlorinated water for extended periods, lice can survive. They temporarily immobilize but recover swiftly once they’re out of the water. So, while a refreshing dip in the pool may sound appealing, it does little in the battle against lice.

Lice Transmission in Pools

Now that we’ve established that chlorine does not kill lice, the next logical question would be – can you get lice from a pool?

Contrary to popular belief, lice do not swim, and hence cannot float from one person’s head to another in a pool. They can, however, crawl. Therefore, sharing personal items like hats, goggles, swim caps, brushes, or towels can potentially spread lice. As such, avoiding group trips to the pool or sharing accessories can significantly reduce the risk of lice transmission.

The Impact of Chlorine on Lice Treatment

Chlorine may not kill lice, but it’s crucial to note its potential impact on lice treatment. Over-the-counter lice treatments may not work as effectively if administered within a day or two of exposure to chlorinated pool water. Therefore, it’s recommended to avoid swimming immediately after a lice treatment to maximize its efficacy.

The Spread of Lice in Swimming Pools

When a person with head lice enters a swimming pool, the lice latch onto the hair strands using their six legs’ claws. This strong grip allows them to withstand friction and remain attached to the host, even underwater. As such, the spread of lice in a swimming pool is highly unlikely unless there’s direct head-to-head contact between individuals.

Preventative Measures: Swimming Caps and Personal Items

To lessen the chances of lice transmission in the water, one could consider using swimming caps. A tightly fitted swimming cap can provide some protection, especially if your child is swimming close to someone with lice.

However, it’s important to remember that sharing personal items like towels is a potential way for lice to spread at the pool. Lice may crawl onto a towel or other shared items, making it essential to avoid sharing personal items at the pool.

The Myth of Chlorine Solution

In desperation, some may consider using a concentrated chlorine solution on their heads to kill lice. However, this is a dangerous idea. Not only will it not kill the lice, but it could also lead to severe skin burns, eye damage, and even chlorine poisoning. Instead, it’s recommended to use safe, professional lice treatments.

Dealing with a Lice Infestation: Professional Help

If you suspect a lice infestation, it’s advisable to seek professional help. Organizations like LiceDoctors, Lice Clinics of America, and Pediatric Hair Solutions offer specialized lice removal services that are safe, effective, and convenient. They employ professional techniques that effectively eradicate lice without the need for harmful chemicals.


So, does chlorine kill lice? The answer, unfortunately, is no. But that doesn’t mean you should let the fear of lice ruin your family’s summer fun. By taking appropriate preventative measures and seeking professional help when necessary, you can enjoy your time in the pool without worry.

Remember, professional lice treatments are more than just a quick fix – they’re a step towards ensuring your child’s comfort and health. Don’t let the pesky parasites stand in the way of your family’s enjoyment this summer.
