Head Lice Symptoms – What Are They, And How Long Before Head Lice Symptoms Appear?

Signs And Symptoms Of Head Lice

The first thing you or your child will notice is something moving around their head, causing tickling and irritation to their scalp.

The first place to check is at the nape of the neck or behind the ears. This is where it is warmest , thickest and most humid so look here first to identify whether or not there is a presence of live lice.

It is saliva of the louse that causes the irritation that leads to the itching, much like a mosquito. If your child is itching behind the ears or at the nape of the neck, this is a very good sign of head lice.

The head louse feeds by biting into the scalp and then inserting its proboscis into a blood vessel. It injects saliva to stop the blood from clotting (again, much like a mosquito).

Another dead giveaway is the itching and scratching caused by the bites and faeces of the wee nasties.

It may take some time for the symptoms to appear.

It takes a while for the saliva to cause the irritation, so itching may not start straight away. If you know they have been exposed to a carrier, it pays to actively seek them out.
