🔴 Chigger Bites
Trombiculidae (larvae)
Intensely itchy bumps where clothing is tight—waistband, socks, behind knees.

Quick identification
- Intensely itchy bumps
- Along clothing lines (waistband, socks)
- After outdoor grass/brush exposure
- Tiny mites are hard to see
- Itching can last days
Appearance of the bite
Typical bite size
Small red bumps; clusters can look larger as a group
Color
Red to pink
Shape
Raised bumps along tight clothing edges
Texture
Intensely itchy; may crust from scratching
About the insect
Insect size
Larvae are tiny (often hard to see without close look)
Insect color
Reddish larvae
Habitat / exposure
Tall grass, brush, and damp outdoor vegetation
- Outdoor time in grassy or brushy areas
- Tight clothing contact lines
- Waistband, sock lines, behind knees
Typical bite pattern
Pattern: Intensely itchy red bumps clustered where clothing constricts
Common location: Waistband, sock lines, behind knees, and other tight edges
Timing: After outdoor exposure in vegetation
Typical number: Often multiple bites along clothing contact lines
How it changes over time
Itching may intensify hours after exposure and can last several days. Scratching commonly worsens the look of the rash.
Key clues for identification
Clothing-line distribution after outdoor brush/grass exposure is a strong clue. Unlike flea ankle clusters tied to pets, chiggers follow waistbands and sock lines. The mite itself is rarely seen—habitat and location matter more than a photo of the rash alone.
Reaction variability
Itch intensity varies widely. Some people get many small bumps; others fewer but very itchy spots. Visual ID of the mite from a skin photo is unreliable.
Lookalikes
- Flea bites
- Bed bug bites
- Contact dermatitis
Basic care
Shower after outdoor exposure, wash clothes, and use itch relief. Avoid heavy scratching.
When to seek medical care
Seek care for severe allergic symptoms, spreading infection signs (increasing warmth, pain, pus, red streaks), or fever.
