What Is Chiggers?
Hives (or urticaria) are red raised bumps or welts on the skin. They can appear anywhere on the body and can look like tiny little spots or large interconnected bumps. Individual hives can last anywhere from a few hours to a week (sometimes longer), and new ones might replace those that fade.
It can be triggered by many substances or situations and usually starts as an itchy patch of skin that turns into swollen red welts.

What Is Chigger?
Chiggers are tiny mite whose parasitic larvae live on or under the skin of warm-blooded animals, where they cause irritation and dermatitis and sometimes transmit scrub typhus. They are tiny members of the arachnid family. Although they are extremely small in size, their bites pack a powerful punch. They barely visible to the naked eye, but it can be view through micro scopes.
Chiggers are found throughout the world. They most commonly live in forests, grassy fields, gardens, parks, and in moist areas around lakes or rivers. They are red in color and may be best appreciated when clustered in groups on the skin. The juvenile forms have six legs, although the (harmless) adult mites have eight legs

Causes of Chiggers
Chiggers have claws that help them grab onto skin. The chigger then attaches its mouth to the skin and injects saliva. The saliva contains an enzyme that breaks skin cells down to liquid form and destroy the host tissue. The area then hardens, and a feeding tube, called a sylostome, develops at the bite area. Chiggers can feed on the skin for a few days through this structure if they are not disturbed

Symptoms/Signs of Chigger
People who have been outdoors in chigger-infested vegetated areas may suffer intense itching 3 to 6 hours after exposure, followed by a dermatitis (skin inflammation).
· A raised or flat red bump on the skin.
· A skin bump resembling a blister or pimple.
· Itching, that can be quite intense.

How to diagnose Chigger     
Chigger bites are typically identified based upon their location on the skin and a history of being outdoors or in contact with vegetation as well as the characteristic itching. Diagnostic tests are typically not required.
