How to Kill Ringworm With Bleach

Ringworm is a highly contagious fungal infection that develops on the top layer of skin. It has nothing to do with an actual worm; the name comes from the circular lesion that develops at the site of infection. Symptoms of ringworm include itching and redness. Other forms of fungal infection closely related to ringworm impact other areas of the body. Treatment usually requires an oral or topical anti-fungal medication. Home treatment may be attempted using liquid bleach, but there are risks associated with applying bleach to the skin.

Step 1

Dilute liquid bleach in a clean glass or container with equal parts bleach and water. Take care not to spill or drip the strong solution.

Step 2

Dip a cotton ball or swab into the solution. Gently dab the ringworm area with the solution. Avoid the surrounding skin. Allow the area to dry.

Step 3

Do not rinse the bleach solution from the area unless you feel discomfort.

Step 4

Wash the area with warm soap and water the next day and administer another application of the bleach solution. Wait until the next day to see if the ringworm is gone. If the bleach treatment does not work, contact your doctor or purchase an over-the-counter anti-fungal cream that is safe for ringworm treatment.

Step 5

Consult your veterinarian before applying a bleach mixture to an animal. Some animals may not tolerate the mixture or could suffer serious health problems from the bleach.
