At what freezing temperature and for how long before lice are killed?

Lice are small, wingless insects that feed on human blood. They can be a nuisance and can also spread diseases such as typhus and trench fever. Lice are killed at temperatures below -10 degrees Celsius (14 degrees Fahrenheit) for at least two hours or -20 degrees Celsius (-4 degrees Fahrenheit) for at least one hour. There are several natural remedies for lice, including:

* Wet combing: This involves using a fine-toothed comb to remove the lice and nits (lice eggs) from the hair while the hair is still wet.

* Suffocation: This involves covering the hair in oil, petroleum jelly, or mayonnaise for at least 8 hours to suffocate the lice and nits.

* Tea tree oil: This oil has been shown to be effective in killing lice and nits.

* Coconut oil: This oil can be used to suffocate lice and nits.

* Apple cider vinegar: This vinegar has been shown to be effective in killing lice and nits.

It is important to note that these natural remedies may not be as effective as chemical treatments for lice. If you are experiencing a lice infestation, it is important to see a doctor or dermatologist for treatment.
