The mites have been reported to be capable of survival for 19 days at 10 °C and 97% relative humidity, although they are unable to move and penetrate skin at temperatures below 20 °C [4,21]. Scabies mites survive less than 24 h in a temperature of 34 °C [2].
The itching is often worse at night, when your skin is warmer. It may take 4 to 6 weeks before the itching starts because this is how long it takes for the body to react to mite droppings.
