Can Diatomaceous Earth Kill Scabies?: Unveiling the Truth
Can diatomaceous earth potentially play a role in managing scabies? While some evidence suggests it might offer relief, its effectiveness against scabies remains unproven and unreliable as a sole treatment; consult a doctor for proven medical treatments.
Understanding Scabies
Scabies is a highly contagious skin infestation caused by the Sarcoptes scabiei mite. These microscopic mites burrow into the upper layer of the skin where they live and lay their eggs. This burrowing causes intense itching, often worse at night, and a pimple-like rash.
- Transmission: Scabies spreads through prolonged, direct skin-to-skin contact with an infested person. Less commonly, it can spread through sharing contaminated items like clothing or bedding.
- Symptoms: The classic symptom is intense itching, particularly at night. A rash typically appears, characterized by small, raised bumps or blisters. Common locations include the wrists, elbows, armpits, fingers (especially between the fingers), groin, and buttocks.
- Conventional Treatment: Standard medical treatments for scabies typically involve prescription creams or lotions containing permethrin or ivermectin. These medications kill the scabies mites and their eggs.
Diatomaceous Earth: A Natural Alternative?
Diatomaceous Earth (DE) is a naturally occurring, siliceous sedimentary rock composed of fossilized remains of diatoms, a type of hard-shelled algae. There are two main types of DE: food-grade and filter-grade. Only food-grade DE is considered safe for human use. Filter-grade DE is used for industrial purposes and is toxic.
- How it Works: DE works by absorbing lipids from the waxy outer layer of insects’ exoskeletons, causing them to dehydrate and die. This abrasive action can damage the mite’s cuticle, leading to moisture loss.
The Potential Benefits of Diatomaceous Earth for Scabies
While research directly supporting DE’s efficacy against scabies in humans is lacking, some anecdotal evidence and studies on similar mites suggest potential benefits.
- Mite Control: DE has been shown to be effective against various insects and mites in laboratory settings and agricultural applications. This suggests it could potentially kill scabies mites, but more research is needed.
- Natural Alternative: For individuals seeking natural alternatives to conventional medications, DE may be considered an option, but only in conjunction with, and never as a replacement for, medical advice and prescribed treatments.
- Cost-Effective: Food-grade DE is relatively inexpensive compared to prescription medications.
Using Diatomaceous Earth Safely
If considering using DE for scabies, strict adherence to safety guidelines is crucial. Always use food-grade DE.
-
Application:
- Lightly dust your mattress, bedding, and furniture with food-grade DE.
- Wash bedding and clothing in hot water and dry on high heat.
- Apply a very thin layer of DE to affected skin areas. Avoid getting DE in your eyes, nose, or mouth.
- Leave on for a few hours, or overnight, then wash off gently.
- Repeat daily for several days.
-
Precautions:
- Always wear a mask when handling DE to avoid inhaling the dust, which can irritate the lungs.
- Do not apply DE to broken skin or open wounds.
- If irritation occurs, discontinue use.
Common Mistakes When Using Diatomaceous Earth
Many individuals using DE for scabies make preventable mistakes that reduce its effectiveness or increase the risk of adverse effects.
- Using the Wrong Type of DE: Only use food-grade DE. Filter-grade DE is toxic and should never be used on the skin or ingested.
- Applying Too Much DE: Applying too much DE can cause excessive dryness and skin irritation. A very thin layer is sufficient.
- Inhaling DE Dust: Inhaling DE dust can irritate the lungs. Always wear a mask when handling DE.
- Relying on DE as the Sole Treatment: Diatomaceous earth should not be used as the sole treatment for scabies. It should be used in conjunction with conventional medical treatments prescribed by a doctor.
- Ignoring Personal Hygiene: Neglecting proper hygiene practices, such as washing bedding and clothing frequently, can hinder the effectiveness of DE.
- Not Treating Everyone in the Household: Scabies is highly contagious, so it’s essential to treat everyone in the household, even if they don’t show symptoms.
The Importance of Consulting a Doctor
It is crucial to consult with a doctor or dermatologist for a proper diagnosis and treatment plan for scabies. While DE may offer some relief, it should not be used as a substitute for conventional medical treatments. A doctor can prescribe medications that are proven to kill scabies mites and their eggs effectively. They can also advise on proper hygiene practices to prevent re-infestation and spread the condition. Self-treating with DE alone carries the risk of prolonging the infestation and potentially leading to complications.

Frequently Asked Questions About Diatomaceous Earth and Scabies
1. What is food-grade diatomaceous earth, and how does it differ from filter-grade?
Food-grade DE is a type of DE that has been processed to remove impurities and is considered safe for human and animal consumption. Filter-grade DE, on the other hand, is used in industrial applications like filtration systems and contains higher levels of silica, making it unsafe for ingestion or skin contact. Always ensure you are using food-grade DE for any potential use involving humans or animals.
2. Are there any scientific studies that prove diatomaceous earth kills scabies mites?
Currently, there are no peer-reviewed scientific studies that specifically demonstrate the effectiveness of diatomaceous earth in killing scabies mites on humans. While some studies show its effectiveness against other types of mites and insects, more research is needed to confirm its efficacy against Sarcoptes scabiei.
3. What are the potential side effects of using diatomaceous earth on the skin?
While food-grade diatomaceous earth is generally considered safe, it can cause skin irritation and dryness, especially with prolonged use. Some individuals may experience allergic reactions. It is crucial to perform a patch test on a small area of skin before applying it to larger areas and to discontinue use if irritation occurs.
4. How long does it take for diatomaceous earth to kill scabies mites?
There is no definitive answer to this question, as the effectiveness of diatomaceous earth on scabies has not been scientifically proven.
