Scabies is a contagious skin condition caused by the tiny burrowing mite Sarcoptes scabiei. This pesky parasite burrows into the upper layer of the skin, where it lives and lays its eggs, causing intense itching and a pimple-like rash. It’s a global health problem that affects millions of people every year. But, does heat kill scabies? Let’s delve into the facts and find out.
Yes, heat can kill scabies. Studies show that all scabies mites die when exposed to a temperature of 50°C (122°F) for 10 minutes. However, while heat can kill scabies mites and their eggs, it should not be the only treatment method used. It is crucial to also follow prescribed medical treatments and environmental control measures to effectively treat and prevent scabies infestations.
The Impact of Heat on Scabies
Heat can have a significant impact on scabies mites and their eggs. According to a study by Arlian et al., all scabies mites were dead after being incubated at 45°C for 4 to 20 hours. The Centers for Disease Control and Prevention (CDC) states that scabies mites will die if exposed to a temperature of 50°C (122°F) for 10 minutes. Another study found that more than 35 minutes at 50°C can kill all scabies mites and their eggs.
To eliminate scabies mites from items such as bedding, clothing, and towels, it is recommended to machine-wash the items using hot water and dry them on high heat. Washing bed linen, nightwear, and towels at a temperature above 50°C (122°F) can help kill the mites. Steaming your mattress can also be effective in killing scabies mites, as heat is lethal to them.
Methods to Apply Heat
When it comes to treating scabies with heat, there are several methods you can follow:
- Wash and dry clothing, bedding, and towels: Machine-wash these items in hot water and dry them in a hot dryer or dry-clean them.
- Seal items: If you cannot wash certain items, place them in a plastic bag for at least 72 hours, after which the scabies mites will have died.
- Use a steam cleaner: For mattresses and other items that cannot be put in the washing machine, you can use a steam cleaner with high-temperature steam that’s at least 140°F (60°C) to kill scabies mites.
Precautions and Side Effects
Like any treatment, precautions must be taken when using heat to treat scabies. Ensure to treat all household members and close contacts at the same time to prevent reinfestation. Environmental measures, such as washing linens, towels, and clothing in hot water, are also crucial to prevent recurrent infestation.
While heat can kill scabies mites if exposed to a temperature of 50°C (122°F) for 10 minutes, relying solely on heat treatment is not an effective way to treat scabies. It is crucial to follow the prescribed medical treatments and environmental control measures to ensure successful treatment and prevent reinfestation.
In conclusion, while heat can indeed kill scabies mites and their eggs, it is not a standalone treatment for scabies. Heat treatment should be combined with prescribed scabicides for a comprehensive approach to managing and preventing scabies infestations. Remember, always consult with a healthcare professional for appropriate treatment options and follow their recommendations for managing scabies.
