Fear of Mice and Rats

Why musophobia never settled on a single spelling

English Wikipedia carries three of them, each built from a different language:

• musophobia, from the Greek mys
• murophobia, from the Latin mure, by way of the taxonomic adjective for the family Muridae
• suriphobia, from the French souris

The 2008 edition of Doctor, Kahn and Adamec's encyclopedia lists suriphobia and immediately redirects to its own heading, mice, fear of.

The plainest reading of that muddle is that nobody with authority ever needed the word. A term used in clinical practice acquires one spelling. A term that lives in reference lists accumulates variants, because each list-maker builds it from whichever language came to hand.

How musophobia differs from ordinary concern about rodents

Wikipedia's article does something few phobia articles bother with: it separates the phobia from the reasonable version before saying anything else. Concern about rats and mice getting into stored food is, in its phrasing, potentially universal to every time and place where grain has been kept, and it is not a phobia. The phobia is the disproportionate case.

That distinction is load-bearing in a way it is not for spiders or clowns. Rodents in a food supply are a genuine hazard with a documented history, so the ordinary reaction to finding one in a kitchen is not fear out of proportion to anything.

How the startle reflex becomes a phobia

The mechanism the article proposes is a socially acquired response built on top of the startle reflex, which is the involuntary reaction to sudden movement that humans share with most animals. A mouse is small, fast, and appears without warning at the edge of vision. The startle is the raw material; what makes it a phobia is what gets learned on top of it.

The article is careful to allow that a single fright can develop into anxiety that warrants treatment, and equally careful not to claim that the usual case is a disorder at all. That is a more restrained position than most phobia writing takes.

How musophobia is classified and acquired

The DSM-5 files it as an animal type specific phobia and names it among the commonest of them, alongside the fear of snakes and the fear of spiders. Onset is typically in childhood, as with the other animal phobias, and three acquisition routes are documented:

• a direct traumatic experience, such as being bitten
• watching somebody else react, which is where the parent on the chair does its real work
• exposure to negative information about what rodents carry

That third route loops back into the mechanism. Fear of mice has been recorded across history, plausibly because of the diseases rodents spread, and the strongest single case is the bubonic plague, carried by fleas that travelled on rats.

Whether disgust or danger drives the fear of mice

Matchett and Davey proposed in 1991 that animal phobias of this kind are rooted predominantly in disease avoidance rather than in defence against a predator, which is the argument that makes the startle account complete rather than replacing it. A mouse is not dangerous, and sufferers say so themselves by describing the animal as dirty or disgusting at least as often as frightening.

The avoidance that follows is geographic and specific. Attics. Subway stations. Fields. The home of a friend who keeps a pet mouse or rat. It extends past the animal to photographs and videos of one, which is the usual sign that the image is doing the same work as the thing. Exposure treatment is the most effective intervention, working through graduated and repeated exposure to mouse-related material.

Whether elephants are really afraid of mice

The belief that elephants fear mice is old enough to be traced. The earliest known statement of it is in Pliny the Elder's Naturalis Historia, book eight, and Philemon Holland's translation of 1601 renders it:

Of all other living creatures, they [elephants] cannot abide a mouse or a rat.

Zoos and zoologists have since shown that elephants can be conditioned out of the reaction, which suggests it is not fixed. The television programme MythBusters ran the experiment and recorded several elephants avoiding a mouse, so something is there. The Chinese board game dou shou qi encodes the older version of the belief, allowing the rat to defeat the elephant, and several editions of its rules explain that the rat enters the elephant's ear and gnaws into its brain. That is folklore rather than zoology, and the game preserves it either way.

Why the cartoon puts a woman on the chair

The screaming woman on a chair is one of the most durable images in cartoon and sitcom shorthand, and the article states the obvious correction: this fear has always been held by people of both sexes. It then supplies the fact the stereotype was built on, which is that women are about twice as likely as men to have a specific phobia of any kind. A ratio of two to one is not the ratio a century of cartoons depicts.

Fiction has used the fear for terror as well as for comedy. In George Orwell's Nineteen Eighty-Four, published in 1949, Winston Smith's fear of rats is the instrument that breaks him, a cage of hungry rats fixed to his face until he betrays the person he loves. That scene is why the fear has a literary reputation the clinical record cannot support.

Who the patron saint of murophobia is

Gertrude of Nivelles, a seventh-century abbess, is named as the patron saint of murophobia and is invoked against rats and mice generally. She is one of very few fears in the catalogue with a saint assigned to it, which is a form of recognition older than any diagnostic manual and arguably better attested than the modern literature under this word.
