About head lice

Head lices tend to prevail regardless of filthyness.
It may be infected in group life or pools, so if it occurs, it is important for schools, kindergartens, nursery schools, etc. to cooperate and deal with and exterminate early.

Eggs are mostly near the root of the hair.
The hair cast can be removed by hand, but the eggs are stuck to the hair and cannot be removed unless they are swayed.

Head lice eggs become larvae in about 7 days.
It takes about 10 days from larvae to adults, and adults live for about one month, during which time they lay 5-8 eggs a day.
The head lice sucks blood between the larvae and the adult.

It causes suppuration due to itching of the skin of the head and scratching.
