Flea bites typically look like small, red, raised bumps on the skin, often surrounded by a slightly inflamed or discolored halo or ring. They commonly appear in clusters or in a straight line, sometimes described as "breakfast, lunch, and dinner" bites, because a single flea may bite multiple times in close proximity. These bites are most frequently found on the lower legs, especially around the feet, ankles, and calves, but can occur anywhere on the body
. The bites are usually itchy and may cause discomfort. In some cases, scratching can lead to crusting, blistering, or secondary infection. People who are allergic to flea bites may experience more severe reactions, including larger areas of redness, swelling, hives, or even difficulty breathing in extreme cases
. Key characteristics of flea bites include:
- Small red bumps, firm to the touch
- Red or discolored ring or halo around the bite
- Occurrence in clusters or lines
- Intense itching
- Commonly located on lower legs and ankles
Flea bites can sometimes turn purple if bruising occurs from scratching
. In summary, flea bites look like small, red, itchy bumps often arranged in clusters or lines, mostly on the lower legs, with a characteristic red halo around the central puncture point
