Flea Bites on Humans: How to Identify and Soothe

Flea bites are small, itchy and often clustered, which makes them easy to confuse with other bites. Knowing the pattern helps you act on the cause.

The short answer

Flea bites on humans are small, red, very itchy bumps, often in clusters or lines on the ankles, lower legs and waist, sometimes with a red halo. They differ from mosquito bites, which are larger and scattered, and bed bug bites, which more often appear on exposed upper body areas. Avoid scratching, wash with soap and water and use soothing measures advised by a pharmacist. See a doctor if you have signs of infection or an allergic reaction. Deal with the source of the fleas.

How to identify

• Small red bumps, often in groups of three or in lines.
• Concentrated on ankles, lower legs and waist.
• Intense itching that may last days.
• Possible tiny blisters or red halo.

Compared with others

• Mosquito bites: larger, scattered and often on exposed skin.
• Bed bug bites: often on arms, neck and face, in lines.
• Mite and other bites: can look similar, so look at context.

Soothing

1. Wash with mild soap and water.
2. Use a cold compress.
3. Ask a pharmacist about suitable anti-itch treatment.
4. Avoid scratching to prevent infection.
