What are Head Lice?

A louse is a parasite that lives off of human heads and causes a common condition known as pediculosis capitis -commonly known as nits, cooties or simply a head lice infestation, which basically boils down to an infection of the hair and the human scalp.

Once a person has become infected it can take up to six weeks for people to exhibit some of the most common symptoms of a head lice infestation. This is due to the fact that lice and nits have to get used to their environment. However, after the first infection, head lice symptoms tend to appear much sooner. Head lice tend to be extremely contagious and some of the most common places where one could get head lice include places with lots of people and close contact with other human beings.  This is why places such as schools, gyms and churches are some of the most common places where one could “catch the cooties”.

How Do Lice Survive?

Every day many people come to us asking “how long do lice live“, “how long can lice live” or “how long can lice live without a host“. To understand that deeply we should know more about their food. When it comes to nutrition, head lice need tiny amounts of blood which they get from their host in order to survive. It is important to know that this tiny amount of blood doesn’t really represent a health hazard since the amount they drawn from the human scalp is insignificant. However, they use this tiny amount of blood to feed their nits and they use the prongs on their legs to stay on the scalp. Once you remove the head lice using an effective shampoo most head lice will wash out with the shampoo, although using a stainless steel comb can be an effective method to expedite the whole process. When it comes to the life cycle of a louse, you should know that the parasitic relationship that exists between them and humans depends on the availability of food once the lice eggs are done hatching. As long as there is blood available to them, a louse can live up to thirty days on the human scalp. However, the fact that they reproduce at a steady rate means that the problem won’t simply go away on their own.

Get Rid of Lice for Good

Despite the fact that there’s been multiple eradication campaigns to free schools of these nasty bugs, the reality is that it is very difficult to get rid of lice permanently, which is why preventive measures play a huge role in determining how likely humans can go on without getting head lice again. However, the fact that head lice lay eggs –like most other insects– means that they can easily spread from one person to another, even if the problem has seemed to disappear. When it comes to hatching an egg, adult lice secrete a sticky substance through their reproductive organs; this sticky substance eventually hardens and acts as a protective cover for the nits which protects it from the environment and predators, you can easily identify these nits by their yellowish or white color and their grainy texture.

If you think you might have a head lice problem, another dead giveaway of a problem is the fact that head lice move very quickly, and by parting the hair into several layers and exposing it to light and heat you should be able to see quick movement from one layer to another. If this is the case, it is time to start looking for treatment right away!
