Here’s the Life Cycle of Head Lice

The treatment of head lice must be tailored to the stage of the louse in order to be effective. A different approach is required to get rid of lice at the bug stage versus at the egg stage.

First Comes the Bug, Then Comes the Nits

You can not catch an egg (nit). The only way to have nits in your hair is if a bug (louse) landed on your scalp and laid eggs. About a week after a nit is laid, it will hatch. To get rid of nits require physically extracting them from the hair. This is where LiceDoctors comes in. Your lice technician has all of the expertise and tools to ensure that all nits are removed so that they don’t linger and hatch.

Out Comes the Nymph

Once the nits hatch, babies called nymphs emerge. The first few days after a nit is laid it is too small to be seen. When you see nits in the hair, you have no idea how long they have been there and if they are about to hatch. At the nymph stage the lice are very vulnerable; they are too small to move or reproduce and they no longer have the protection of their shell. It is best to suffocate lice when they are at this stage.

From Nymph to Mature Bug

A nymph takes about a week to 10 days to mature into a louse and start to lay eggs. Each mature 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. When a louse is mature it moves very quickly and can be challenging for an untrained person to find and extract.

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.
