What is a Chigger?
Chigger is the common name used to describe the larva of a harvest mite and is only one of 30,000 species of mites. Chiggers are also called jiggers, redbugs and harvest mites. While in the larva phase, the chigger is invisible to the naked eye (0.5 mm or 1/150 ot 1/120 inch in diameter). The larva has six legs, is hairy, yellow, orange or light red and travels rapidly.

Where do they live?
Chiggers live and breed on the ground, inhabit areas of tall grass but also like to inhabit shrubs, plants, weeds and thick vegetation that will provide them protection. They especially inhabit areas where small rodents are abundant. They are associated with damp but well drained locations such as ponds and stream banks. They prefer shade and moist areas, but will travel great distances for food. Chiggers will also be found in parks, picnic sites, golf courses, yards and all sorts of other recreational areas so it is hard to predict where they will be found. When people sit in Chigger infested areas, they may get severe chigger bites in the crotch area and waistline, especially under elastic bands of underwear. Some people have suggested that you can check to see if an area is chigger infested with a simple technique. A six-inch squares of black paper placed vertically in the grass will become covered with chiggers if they are present.

Life Cycle
The harvest mite passes through four stages of development: egg, larva (chigger), nymph and adult. The adult (bright red, eight legged and looks like a velvety spider) can be seen crawling over the soil, pavement or lawns. In this stage the harvest mite is completely harmless. They eat small invertebrates, their eggs and organic matter. In the spring, the adult female mites will lay eggs in-groups of up to 400 in the soil. Once hatched, the larva is what is known as the chigger. The chigger will feed on an animal or human (see Feeding Habits below). Once the chigger is full, the chigger disconnects from its host and molt to non-parasitic eight-legged nymphs, which mature to the adult stage. The life cycle is completed in about 50 to 70 days. The adult females live up to one year and produce offspring during this time. In humid climates, there may be two to three generations per year. So, the chigger threat can be as early as May and last through until the first killing frost. The adult will spend the winter in the ground so that they are protected from the freezing temperatures.

Feeding Habits
Chiggers will feed on vegetation but they need protein, which they get from humans or warm-blooded animals. They will bite dogs, cats, snakes, turtles, birds, and people or just about anything which passes their way. Chiggers move from the tips of grass or fallen leaves onto their passing meal. Once a Chigger larva has made it onto a human's skin, they will crawl upward until they find a spot where they will be somewhat confined, the clothes fit tightly and the skin is thin and moist. Most common areas of infection are tops of feet (under socks and shoes), back of knees, the crotch, under tight fitting underwear, waistbands, armpits and around a bra.

The feeding processes begin when the Chigger pierces the skin and attaches to the opening of a hair shaft and injects saliva, which acts as a digestive enzyme. The Chigger larva does NOT burrow into the skin, as some people may believe. The enzyme dissolves the tissue of the host and prevents blood from clotting. The digestive fluid causes surrounding tissues to harden, forming a straw-like feeding tube of hardened flesh (stylostome) which is used to sucks up the skin cells that are now liquid. The fluid causes inflamed tissues which hide the chigger. Feeding could continue for up to four days if undisturbed. Once feeding is completed, the chigger will then disconnect. (see Life Cycle above)

Reaction
Most people develop a small reddish welt with a hard, white central area within 24 hours of a chigger bite. The effect of the chigger's saliva is what causes the intense itching. The itching may persist for up to two weeks after the chigger has disconnected. Many people have gotten infections from scratching the bites from Chiggers. Some are so bad that doctors need to treat the infections. Many people will say that the bite from a chigger is the most irritating and long lasting of all insect bites. The bite from a chigger can be as irritating as an acute case of poison ivy or poison sumac. In North America, the tiny larval (Chigger) does not pose a real medical health concern. Stop the itch before you scratch to infection. Treatment is available for FAST relief.
 
that was the most informative post in interference history
 
Gah, how I hate chiggers. Evil little bastards. *memories of visiting the relatives in Looziana*

there is this great insect in Indonesia called a chudidara and the bite iches like a mofo! Turns into a hard welt too. :mad: bugs. blah.
 
think back hard now...

do you live in rattler country? those guys carry a pesky little nip
