In the past, when the sanitary conditions at home were poor and mosquito control supplies were scarce, almost every household had lice. Especially in rural areas, you would often see some elderly people carrying quilts every winter. I rummaged around to look for lice, and when I found them, I squeezed them with my fingernails, and with a pop, a black louse was wiped out. However, removing lice with bare hands cannot remove the root at all. A large number of lice eggs are still present in the corners of the house, and they soon come out again.

Modern people rarely see lice anymore, and they don’t know what lice look like. Below I will show you some photos of lice

Nowadays, there are very few lice on people, but they are still very common on animals, especially those who keep dogs and cats at home. If these animals often go out and run around, they can easily attract lice and ticks. Small bites like insects.

Lice look disgusting when magnified. Lice are parasitic. If they are separated from the human body or animals, they will die in 3-5 days. The best way to really avoid attracting lice is Wash clothes frequently, bathe frequently and maintain good hygiene. You can also use pesticides to kill viruses at home regularly.

So how do these lice come about?

1.2 million years ago, the ancestors of lice began to evolve. About 20,000 years ago, a kind of lice began to parasitize the human body that walked upright at that time, and slowly spread among the people through human contact. spread until now.

The occurrence of lice in the home is mainly caused by the external environment, such as contact between animals and people. Below are photos of tick bites
