The itching of scabies is due to a hypersensitivity reaction (allergy) to mites and their feces, so itching may continue for several weeks after treatment even if all the mites and eggs are killed. However, if itching still is present two to four weeks after treatment or if new burrows or pimple-like rash appear, retreatment may be necessary.
