If you've been bitten by sand fleas, the best approach for relieving the itching and discomfort is to avoid further scratching by using an anti-itch lotion or cream. Additionally, you should take steps to protect yourself from future flea bites in order to reduce the risk of potential infection.
Apply an anti-itch lotion or cream, such as cortisone, as soon as you notice the irritation or itching caused by sand flea bites. Do not scratch the irritated area, as this can lead to infection. Additionally, iceberg lettuce can be placed on the affected area for 10 minutes to reduce inflammation.
