How to Get Rid of Chiggers (Berry Mites)
Chiggers—also known as berry mites—are tiny pests that pack a big punch. These microscopic larvae of a mite species lurk in tall grasses, brushy areas, and humid environments. They’re especially common in the southern United States during the warmer months.
A chigger bite can leave behind red, itchy welts that last for days, making outdoor time miserable. Whether you're dealing with a backyard infestation or need relief from bites, this guide covers how to get rid of chiggers in your yard and how to treat chigger bites fast.
What Are Chiggers (a.k.a. Berry Mites)?
Chiggers are the larval form of Trombiculidae mites, often referred to as berry bugs, harvest mites, or red bugs. They’re nearly invisible to the naked eye—about 1/150th of an inch—but can cause intense skin irritation.
Chiggers don’t burrow into the skin, despite popular belief. Instead, they attach to the surface, inject an enzyme that breaks down skin cells, and feed for a short time before dropping off.
What Do Chiggers Look Like?
They’re tiny red or orange mites that may cluster in groups on clothing or skin.
How Do You Know If You Have Chiggers in Your Yard?
Chiggers love warm, humid, and overgrown environments. Signs you may have a chigger problem in your yard include:
- Frequent, unexplained bites after spending time outdoors.
- Clusters of itchy red welts—especially around ankles, waistlines, or sock lines.
- Activity in tall grass, leaf litter, or dense shrubs.
- Heavy pest activity from late spring through early fall.
How to Get Rid of Chiggers in Your Yard
Eliminating chiggers from your property requires a mix of pest prevention and targeted treatments. Here’s how to do it:
Yard Maintenance
- Mow the lawn regularly and keep it short.
- Trim shrubs and remove brush or tall weeds.
- Clear leaf piles, woodpiles, and compost where mites can thrive.
Natural Chigger Treatments
- Diatomaceous earth: Sprinkle around affected areas to dehydrate and kill mites.
- Sulfur powder: A traditional and effective repellent.
Safe Insecticides
For serious infestations, consider EPA-registered pesticides such as:
- Bifenthrin
- Permethrin
- Carbaryl
Apply early in the morning or late evening and follow label directions carefully.
Tip: Reapply insecticides after rainfall or heavy watering.
What Kills Chiggers Instantly?
To kill chiggers on contact:
- Use insecticides containing permethrin or bifenthrin on outdoor areas.
- For your body or clothing, hot, soapy showers immediately after exposure can remove and kill chiggers.
- Sulfur dust or DEET sprays can help repel or kill them before they latch on.
How to Prevent Chigger Bites
Avoid bites with these prevention tips:
- Wear long sleeves and pants tucked into socks when walking through grassy or wooded areas.
- Apply DEET-based insect repellent to exposed skin.
- Treat clothing with permethrin spray before outdoor activity.
- Shower and change clothes immediately after being outside in potential chigger areas.
How to Get Rid of Chigger Bites
Chigger bites can last up to a week and cause severe itching. Here’s how to relieve them:
Home Remedies for Chigger Bites
- Calamine lotion to soothe itching
- Oatmeal baths or baking soda paste
- Over-the-counter antihistamines like Benadryl
- Hydrocortisone cream to reduce inflammation
What NOT to Do:
- Don’t scratch excessively—this can lead to infection.
- Don’t apply nail polish or alcohol to “suffocate” them—they’re already gone.
See a Doctor If:
- The bites become infected or don’t heal.
- You experience severe swelling or allergic reactions.
Do Chiggers Stay in Your Skin?
No—chiggers do NOT burrow into the skin. The intense itching is a reaction to their saliva, which contains an enzyme that digests skin cells. The chigger detaches after feeding and falls off, usually unnoticed.
Where Do Chiggers Come From?
Chiggers are found throughout the southern and midwestern U.S., especially in:
- Overgrown lawns
- Forest edges
- Near lakes, streams, or marshes
They thrive in warm, humid environments, especially from May to September.
Common sources of exposure include hiking, camping, gardening, and playing in uncut grass.
How Long Do Chigger Bites Last?
Chigger bites usually last 3 to 7 days, though severe reactions can take up to two weeks to heal. Consistent treatment and avoidance of scratching can help speed up recovery.
