Are they in Louisiana?
Chiggers are very common and well established throughout Louisiana. They thrive in the state's warm, humid climate and are present year-round, unlike in northern states where they become dormant in winter. Chigger populations are especially abundant in central and northern Louisiana, in areas around the Kisatchie National Forest, regions near the Mississippi River delta, and throughout the state's swampy and wooded areas. Peak activity runs from May through September, with the highest numbers during the hot, humid months. Chiggers remain active at lower levels during fall and winter months in Louisiana because temperatures rarely drop cold enough to make them dormant.

How dangerous is it?
Chigger bites are uncomfortable and cause intense itching, but they are not medically serious. Chiggers inject saliva that causes an allergic reaction in human skin, leading to the characteristic itch. They do not inject venom, and serious medical complications from chigger bites are not documented in Louisiana. A bite site will itch intensely for one to two weeks. Scratching can lead to minor secondary skin infections, but this is preventable by resisting the urge to scratch. Bites do not cause fever, serious swelling, systemic illness, or lasting damage. Both children and adults experience the same mild effects from chigger bites. If you have very severe itching or notice signs of infection from heavy scratching, medical attention is available, but most people in Louisiana manage chigger bites easily with simple over-the-counter itch relief products. The main reason to prevent chigger bites is personal comfort, not medical emergency. For more on chigger in Louisiana, see ourLouisiana chigger guide.
How to recognize one
The challenge with chiggers is that they are nearly impossible to see on your skin. Adult chiggers are smaller than a pinhead, measuring only about 0.3 millimeters long. The larvae are even smaller and nearly invisible to the naked eye. When you look at chigger bite sites, you will see a small red bump or dot, but the chigger itself has already left your skin. Chiggers hide in tall grass, leaf litter, woodpiles, brush, and low vegetation in Louisiana before they attach to passing animals or humans. They climb into your clothing and settle in warm, protected areas such as between your toes, around your ankles, at your waistband, or in the creases of your body. They prefer these hidden spots because they need warmth and moisture to feed properly. The best way to prevent bites is to avoid walking through chigger habitat or to wear protective clothing and use repellents. You can also browseLouisiana wildlife.
What to do if you are bitten or stung
If you think you have been bitten by chiggers, the first step is to stay calm. Remove any tight clothing, rings, or bracelets from the affected area to prevent swelling. Wash the area gently with soap and water. Keep your hands away from the bites as much as possible to avoid infection from scratching. If itching is severe, you can apply over-the-counter itch relief products such as hydrocortisone cream or calamine lotion. Antihistamine medications can help reduce itching if it disrupts sleep or daily activities. You do not need emergency medical care for a chigger bite unless signs of serious infection develop. This is general information, not medical advice; if you are bitten, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. Most chigger bites resolve completely within one to two weeks without any specific treatment beyond basic care. See all of ourwildlife guides.
How to prevent encounters
The best way to protect yourself from chigger bites in Louisiana is to avoid tall grass and weedy areas, especially during warm months when chiggers are most active. If you must walk through grassy or brushy terrain, wear long pants, long sleeves, and closed shoes. Tuck your pant legs into your socks to create a barrier that prevents chiggers from crawling up your legs. Apply insect repellent containing DEET to your exposed skin and clothing before entering high-risk areas. Reapply repellent after swimming or sweating in Louisiana's hot, humid climate. Clear woodpiles, dense brush, and tall weeds around your home to reduce chigger habitat. Keep grass mowed short, especially around the edges of wooded areas and swamps. After spending time outdoors in Louisiana, especially in warm months, shower and change your clothes immediately. Wash your outdoor clothing in hot water and dry on high heat to kill any chiggers that may have attached to fabric.
Where in Louisiana and when
Chiggers are found throughout Louisiana in any area with suitable habitat. They are especially common in northern Louisiana, around the Kisatchie National Forest, regions along the Mississippi River and its delta, areas near Atchafalaya Basin, and in the state's various swamps and wooded areas. Grasslands, prairies, and brushy areas throughout Louisiana provide habitat. Chiggers are present statewide, including in urban areas with parks and green spaces. Peak activity runs from May through September, with the highest numbers in July and August when temperatures and humidity are optimal. Unlike in cooler states, chiggers remain active at reduced levels during October through April in Louisiana because winter temperatures rarely drop cold enough to make them completely dormant. Chiggers are strictly outdoor creatures and do not infest homes or buildings in Louisiana.
Harmless lookalikes
Chiggers are so small that you will never see an actual chigger on your skin. What you will observe is the red bump or irritation caused by your body's reaction to the chigger's saliva, not the chigger itself. By the time itching develops and you see the bump, the chigger has already dropped off. Because chiggers are invisible and the symptoms are simply itchy bumps, many people in Louisiana mistake chigger bites for heat rash, mosquito bites, or other common skin irritations. The itch from chiggers tends to be more intense and longer lasting than mosquito bites. Small spider bites and flea bites can look similar but are equally minor and harmless. The most reassuring news is that if you have itchy red bumps on your legs and ankles after outdoor time in Louisiana, they are far more likely to be chigger bites than anything serious or dangerous. Chigger bites do not become infected unless you scratch them heavily and create open wounds.
