Musophobia is a relatively common phobia. It is estimated that up to 1 in 10 people have some degree of fear of mice or rats.

There are a number of reasons why people might develop musophobia. Some people may have had a negative experience with mice or rats in the past, such as being bitten. Others may have learned to fear mice or rats from their parents or other caregivers. 

Musophobia can have a significant impact on a person's life. It can prevent people from going into certain places, such as basements, attics or out in the countryside.
