Duration of Scabies

Scabies subsides once the mites have been killed. Once treatment starts, this typically takes a week. After treatment, even if all the mites have been eradicated, you may have residual itching for up to a few weeks. If the itching lasts more than two to four weeks, or if you notice new burrows or the pimple-like scabies rash, you might need retreatment.
