Everything You Need to Know About Scabies: Treatment and Why It Can Be Hard to Eradicate
Scabies is a contagious skin condition caused by the Sarcoptes scabiei mite. It leads to intense itching, rashes, and discomfort. Many people wonder why scabies is so persistent and difficult to eliminate. This blog post answers the most common questions about scabies and explores effective treatments, including sulfur-based remedies.
Is Scabies Hard to Get Rid of?
Yes, scabies can be surprisingly persistent. The mites burrow into the skin, making it difficult for topical treatments to reach them all at once. Reinfestation from bedding, clothing, or close contact with untreated individuals can also contribute to prolonged infections. Effective treatment requires thorough application of medicated creams or ointments over the entire body.
Tip: Using sulfur ointments (8–10%) or other dermatologically-approved treatments can help target mites while being safe for sensitive skin.
Why is Scabies So Hard to Get Rid Of?
Scabies is hard to eliminate due to:
-
Hidden mites: They burrow under the skin, making them hard to reach.
-
Eggs: Mites lay eggs, which hatch in several days, requiring repeated treatment.
-
Transmission: Close contact with untreated individuals or contaminated bedding can cause reinfection.
-
Resistance: Overuse of first-line treatments like permethrin has led to cases of resistant scabies mites.
Sulfur-based treatments have historically been effective against resistant mites due to their keratolytic and anti-parasitic properties, making them a useful alternative or adjunct therapy.
Does Scabies Stay With You for Life?
No. Scabies does not stay with a person for life. With proper treatment, scabies can be completely eradicated. However, itching may persist for 2–4 weeks even after mites are gone due to the body’s immune reaction.
Important: Early diagnosis and complete treatment are key to preventing reinfestation. Sulfur ointments, permethrin cream, or oral ivermectin are all effective when used correctly.
Can You Completely Get Rid of Scabies?
Yes, scabies can be completely eliminated with:
-
Correct application of topical treatments (permethrin, benzyl benzoate, or sulfur-based ointments).
-
Cleaning bedding and clothing with hot water to prevent reinfection.
-
Treating close contacts simultaneously.
Sulfur ointments (8–10%) are a safe and effective option, especially in cases where permethrin-resistant mites are suspected.
Do Scabies Live in Mattresses?
Scabies mites cannot survive long away from human skin, typically dying within 48–72 hours. While they do not burrow into mattresses, contaminated bedding, clothing, or towels can temporarily harbor mites and cause reinfestation if not washed properly.
Pro tip: Wash all bed linens, towels, and clothing in hot water and dry on high heat to eliminate mites.
Is It Normal to Have Scabies for 4 Months?
Yes, it can happen if scabies is misdiagnosed, left untreated, or if reinfestation occurs. Incomplete treatment or use of ineffective medications can prolong infection.
-
Persistent itching beyond a few weeks may indicate resistance to permethrin or improper application.
-
Sulfur ointments provide an alternative, especially for people who cannot tolerate stronger chemicals or have resistant scabies strains.
Why is Permethrin Not Killing Scabies?
Permethrin may fail due to:
-
Resistance in scabies mites, reported in several recent studies.
-
Incomplete application (not covering all body areas or missing eggs).
-
Reinfestation from untreated contacts or contaminated fabrics.
Alternative: Sulfur ointments (8–10%) remain effective against resistant mites and have a long history of clinical use. They are safe for children, pregnant women, and those sensitive to permethrin.
Conclusion
Scabies is treatable, but persistence and resistance can make it challenging. Proper application of topical treatments, careful cleaning of clothing and bedding, and treating all close contacts are crucial steps. Sulfur ointments offer a natural, effective, and safe solution for stubborn or resistant scabies cases.
