Mites can last a varying amount of time depending on whether they are on a host or off of one.
-
On a Human Host: Mites can live on a human host for an extended period, with the onset of itching typically occurring two to six weeks after initial exposure in individuals without prior infestations. However, in people who have been previously infested, symptoms can develop much faster, typically 1-4 days after re-exposure.
-
Off a Human Host: According to provided information, when away from the human body, mites do not survive for more than 48-72 hours.
Therefore, the lifespan of mites depends greatly on their environment.
