How long can scabies live in a mattress?


Scabies is a highly contagious skin condition caused by the Sarcoptes scabiei mite. It can cause intense itching and a rash, and it can easily spread from person to person through close physical contact. One common concern among individuals with scabies is how long the mites can survive on various surfaces, including mattresses. In this article, we will explore the lifespan of scabies mites in a mattress and provide important information for preventing the spread of scabies.

Survival of Scabies Mites in a Mattress

Scabies mites are known to survive for a limited time away from the human body. They rely on human skin for their nourishment and reproduction. While scabies mites can survive for a few days to a couple of weeks away from the body, their chances of survival decrease significantly as time goes on.

When scabies mites come into contact with a mattress, they can burrow into the fabric or hide in the crevices. However, without a host to feed on, their survival is compromised. The lack of nourishment and the absence of a suitable environment eventually lead to their demise.

Factors Affecting Scabies Mite Survival

Several factors can influence how long scabies mites can survive in a mattress:

Temperature and Humidity: Scabies mites thrive in warm and humid environments. Higher temperatures and humidity levels can prolong their survival. However, in dry and cool conditions, their lifespan is significantly reduced.

Exposure to Air: Scabies mites require a certain level of moisture to survive. When exposed to air for extended periods, they can become dehydrated, leading to their death.

Surface Material: The type of material on the mattress can also impact scabies mite survival. Porous materials, such as fabric, provide more hiding places for the mites and may allow them to survive longer compared to non-porous materials like vinyl or plastic.

Presence of Skin Cells: Scabies mites feed on human skin cells. If a mattress has a significant amount of dead skin cells, it can provide a food source for the mites, potentially prolonging their survival.

Preventing Scabies Transmission

To prevent scabies transmission, it is essential to take certain precautions:

Wash Bedding and Clothing: Regularly washing bedding, including sheets, pillowcases, and blankets, in hot water can help kill scabies mites. Additionally, washing clothing, towels, and other items that have come into contact with an infested person’s skin can help prevent the spread of scabies.

Use a Mattress Protector: Using a mattress protector can create a barrier between the mites and the mattress, making it easier to clean and reduce the risk of infestation.

Vacuum and Clean: Regularly vacuuming and cleaning the mattress can help remove any scabies mites or eggs that may be present. Pay close attention to the seams and crevices where the mites may hide.

Avoid Close Physical Contact: Scabies is primarily spread through close physical contact. Avoiding direct skin-to-skin contact with an infested person can help prevent transmission.


Scabies mites can survive for a limited time away from the human body, including on a mattress. However, their chances of survival decrease significantly without a host to feed on and in unfavorable environmental conditions. Taking proper precautions, such as washing bedding, using a mattress protector, and maintaining cleanliness, can help prevent the spread of scabies and reduce the risk of infestation.
