Depends: If uninfected, they should heal within a week. If irritated and scratched, they will last longer, scar up and may become infected. Avoid scratching and apply an antibiotic ointment and keep them clean to enhance healing. May also apply a "liquid bandaid" that looks like clear nail polish to slow itching and infection. Topical Benadryl (diphenhydramine) is useless as are steroids.
