Quick answer
Chigger bites are intensely itchy red bumps clustered where clothing fit tightly - sock tops, waistband, behind the knees. The chiggers themselves are long gone within a day; what's left is a skin reaction that itches for one to two weeks. Shower right after exposure, hot-wash clothes, and treat the itch with hydrocortisone or calamine. Permethrin-treated clothes plus DEET or picaridin on skin is the most reliable prevention.
What do chigger bites look and feel like?
- Small, intensely itchy red bumps that show up 6–24 hours after exposure.
- Bites cluster where clothing fit tightly - sock tops, waistband, bra line, behind the knees.
- A tiny bright-red dot in the center of each bump in the first day or two.
- Itch peaks at 1–2 days and can linger for one to two weeks.
- Often a dozen or more bites at once after a single exposure.
Chiggers don't burrow in or live under the skin. The itch is a reaction to their saliva - that's why scratching the bumps doesn't "let them out".
What else looks like chigger bites?
Mosquito bites
Tell: Larger single welts in random spots; itch fades in a day or two.
Flea bites
Tell: Tight clusters of 3–4 bites mostly on ankles and lower legs.
Bed bug bites
Tell: Lines or zigzags on areas exposed in bed; appear overnight.
Heat rash
Tell: Tiny prickly bumps in covered, sweaty skin folds; not the dot-in-center pattern.
Poison ivy
Tell: Streaky or patchy rash that follows brush contact, often blistering.
What should I do right now for chigger bites?
- 1Shower with warm soapy water as soon as possible - chiggers brush off easily early on.
- 2Wash worn clothes in hot water and run them through a hot dryer cycle.
- 3Apply 1% hydrocortisone cream or calamine lotion to bumps; reapply every few hours.
- 4Take an oral antihistamine if itch is interfering with sleep.
- 5Don't dig at the bumps with fingernails - broken skin invites infection.
- 6Skip the old myth of nail polish over bites; it doesn't work.
When should chigger bites see a doctor?
Chigger bites are itchy but harmless on their own. Get care if bites become infected from scratching (spreading redness, warmth, pus, fever), if welts are very large or covering large areas of the body, or if a child can't sleep through the itch despite home treatment.
How do I avoid chiggers in the yard and on trails?
Yard work and brush clearing
- Wear long pants tucked into socks or boots; long sleeves if you can stand the heat.
- Treat clothes and shoes with permethrin (never on skin) before brushy work.
- Apply DEET or picaridin to exposed skin and to skin under sock tops and waistband.
- Shower and toss clothes in the wash within an hour of coming inside.
Trail and outdoor walking
- Stay on cleared trail centers; avoid sitting in tall grass or leaf litter.
- Choose loose long pants over shorts in chigger country.
- Reapply repellent every few hours on long outings.
- Carry a small towel for a brisk wipe-down before getting back in the car.
Around the yard
- Mow tall grass and clear brushy edges, especially near patios and play areas.
- Trim back overgrowth along fence lines and the wood line.
- Discourage rodents - they're a key host for chigger populations.

View on AmazonWhere do chiggers show up on Delmarva?
Chiggers are a hot-weather Delmarva regular from June through early October - tall grass shoulders along back roads, brushy field edges, fence lines behind farms, and the leaf litter at the wood line at Trap Pond, Pocomoke, and Cape Henlopen. Sitting on the lawn for a backyard cookout, kneeling to weed flower beds, or cutting through a shortcut path can leave you with a constellation of bites under your sock tops by bedtime. Treat clothes with permethrin before yard or trail days, repel exposed skin, and shower as soon as you come inside - that one habit prevents most of the itch.

Frequently asked questions
- Do chiggers burrow under the skin?
- No. Chiggers attach to skin briefly to feed on dissolved tissue, then drop off, usually within a few hours. The itchy bumps are an immune reaction to their saliva, not a bug living under the skin.
- How long do chigger bites itch?
- Most chigger bites itch most intensely for 1 to 2 days and gradually fade over 1 to 2 weeks. Hot showers, scratching, and friction from clothing can extend the itch.
- Does nail polish on chigger bites help?
- No. The chiggers are already gone by the time you see the bumps, so suffocating the bite does nothing. Use 1% hydrocortisone or calamine instead.
- Where do chiggers usually bite?
- On Delmarva, bites cluster where clothing fits tightly: sock tops, waistband, behind the knees, and under bra lines. That pattern alone is a strong tell.
- How do I avoid chiggers in the yard?
- Treat clothes and shoes with permethrin, apply DEET or picaridin to skin under sock tops and waistbands, mow tall grass and brushy edges, and shower within an hour of coming inside.
