Did You Know?
We invite you to test your general knowledge of some of these lesser-known facts about Pediculosis:
Host-Parasite Relationship
According to the World Health Organization, once separated from a human host, head lice cannot thrive for more than a short time.
Combing Technique
For long hair, it may be useful to use a nit comb in the opposite direction (up the hair strands towards the scalp) before combing out normally (from the roots to the ends). This way, nits that are firmly cemented to hair near the scalp can first be dislodged and then removed. Long hair will also require more treatment product. Always follow product use instructions for best results.
Body Heat Required
A nit cannot hatch unless it is in close proximity to the warmth of the human scalp. An egg will surely perish if its distance from the scalp exceeds one centimeter.
Symptoms May Be Delayed
Some kids with head lice will have no outward symptoms, such as persistent scratching behind the ears, for a period of several weeks.
Two Kinds of Lousy
Human body lice (Pediculus humanus) has been implicated in the spread of diseases, including typhus and trench fever, whereas head lice (Pediculus capitis) do not carry disease or pose any serious health threat to the human host.
No Insecticide Spray
Do NOT use insecticide spray in your home on bedding, furniture, etc. Fumigants are potentially toxic to people and animals and are ineffective in controlling head lice.
