1. Head lice have been living with humans for thousands of years, preying on humans all the while. As a matter of fact, mummies discovered in Egypt have been found to have dried up head lice present on their scalps!
2. Oddly enough, the head louse can only prey on humans. Cats, dogs, and all other forms of animals are immune from the itchy little parasites.
3. For some reason, African Americans have been found to be much less likely to be susceptible to cases of head lice. Studies conducted in the field of pediatric dermatology have shown that while the rates of head lice infestation in other races is around ten percent, only half of a percent of African American children catch head lice.
4. The head louse has a period of 7 to 10 days from when the nit is laid until it has hatched. After hatching, the head louse will require 7 to 10 days before becoming a fully grown louse.
5. When the nits are laid, they stick to hair follicles like glue. It can be really tough to get the nits off of the hair follicles, but one method seems to work pretty well: using distilled white vinegar to shake them loose.
6. Although many people think that its a good idea to get their house sprayed for lice when an outbreak occurs, it often isnt necessary. The louse can only live for around 24 hours when not on a human and it is unable to fly or jump. Since all that it can do is crawl, all that you need to do is wash your linens and avoid sitting in common areas such as couches until the problem is solved. Using pesticides across your house could actually prove to be more dangerous than it is worthwhile.
7. Children under age two should not be exposed to the dangerous pesticides that are often used to get rid of lice. It can be damaging to their health, so you should opt for solutions like using a specialized lice comb instead.
8. If the nits that are located on your hair follicles are more than a centimeter away from the scalp, they will not hatch. Lice lay their eggs close to the scalp so that they can get the body temperature necessary to incubate properly.
9. For some reason, women tend to get head lice more often than men. In schools, the girls tend to get head lice more often than the boys.
10. When head lice are born, they are almost clear in color; after feasting on human blood, however, they tend to turn a brownish-red color.
11. Head lice have been roaming the earth, via their hosts for over one million years. It has taken this long for the current design to evolve into what we have today.
12. The head louse has evolved to have the perfect body functions for its terrain. Before mentioning its design you have to remember that it lives in the human hair. The head louse is no bigger than a sesame seed and is tan to brown in color; this offers camouflage in most hair types and a size that can easily be concealed.
13. The female head louse is slightly bigger than the male head louse, while this doesnt strike out as being anything special, what the female can do that is quite unbelievable is to lay between 3 and 6 eggs a day for the whole duration of her adult life.
14. The female also has special saliva that has strong glue like qualities; she uses this to glue the eggs to the hair, near the scalp so they do not easily fall out of the host. This saliva is so strong that the only way to remove the eggs is by manually picking them out by hand as the chemical treatments can kill the eggs but cannot dissolve the strong bond the saliva created.
If you suspect that you may have a head lice infestation, be sure to properly diagnose the issue by having someone carefully examine your scalp, looking for evidence of nits on your hair follicles or lice on your scalp.
