Frequently Asked Questions

What exactly are lice?
Lice are tiny, wingless insects that live on the human body, feeding on blood. There are three types: head lice, body lice, and pubic lice, each preferring different parts of your body to call home.
How do people get lice?
Lice spread mainly through direct head-to-head contact with an infected person. Sharing personal items like hats, brushes, or headphones can also be a culprit. They can't jump or fly, so close contact is key for their transfer.
Can lice survive away from the human body?
These critters need human blood to survive. Away from a host, they can only live for 24 to 48 hours. This means they're not waiting around on your furniture to hop onto the next person, contrary to popular belief.
Are lice dangerous?
While they're more of a nuisance than a health hazard, lice can lead to uncomfortable itching and scratching. This scratching can cause sores on the scalp that might get infected. Otherwise, they don't spread diseases.
Can pets spread lice to humans?
Nope, pets are off the hook here. The lice that live on humans are different from the ones found on pets. So, your furry pals can't pass their lice onto you, nor can you pass yours to them.
What's the best way to get rid of lice?
Treatment usually involves over-the-counter or prescription medications that kill lice and their eggs. It's also important to wash bedding, hats, and clothes in hot water and vacuum any areas where the infested person has laid their head.
Can lice become resistant to treatments?
Yes, unfortunately, some lice have grown resistant to traditional treatments. If over-the-counter options don't work, a doctor might prescribe a stronger medication. It's also crucial to follow treatment instructions carefully to avoid resistance.
How can I prevent getting lice?
Avoiding head-to-head contact is key. Also, don't share items that touch the head like hats or hairbrushes. Regularly checking your family's hair for lice, especially if there's an outbreak at school or work, can help catch them early.
