How Long Does It Take for Nits (Lice Eggs) to Hatch?

How Long Does It Take for Lice Eggs to Hatch

A mom called us from Tucson a couple of months ago to say that she and her kids had been exposed to head lice and she was pretty sure that they now had nits (eggs) in their hair. She was leaving for the weekend and wanted to know how long it would take for those eggs to hatch. Basically she wanted to know if she could hold off on picking out the nits until she returned home in two days. We explained to her that it takes 8-12 days for nits to develop and hatch. The catch is that you do not know for sure how long the eggs have been in the hair. In order to have nits, a bug has to have been in the hair. You can't catch nits; they must be laid by a bug. While it typically takes about 1 to 2 weeks for eggs to hatch, the first few days after a nit is laid it is too small to be seen. The point is that when you see nits in the hair, they have already been there for days and could hatch at any point. While the LiceDoctors treatment plan works no matter how many bugs or nits are in the hair, it is obviously better to find a case early.

From Louse To Nit

Worrying About Lice Back In School

Once a nit hatches, a baby bug or nymph emerges. That nymph takes about a week to 10 days to mature into a louse and start to lay eggs. A louse lays up to 6-10 eggs a day and can live 30 days before it dies. That means each bug can lay 180-300 eggs before it dies. The life cycle of lice continues until all of the bugs and nits are removed from the hair. If the head is not effectively treated the case will continue to get worse. Lice cases do not go away by themselves. LiceDoctors offers a safe, all-natural treatment that will leave you lice-free.

What Happened to Tucson Mom?

By the way, the Tucson mom did decide to continue with her plans for the weekend. We arrived at her house late Sunday night and we found some nits and a few live nymphs; apparently, the nits had been there for at least a week and had therefore hatched. We eradicated the problem and she was grateful that we treated the case before it had a chance to advance any further. Learn more about our Tucson lice removal treatment now!
