Chiggers are not actually insects, but instead the juvenile type of a form of mite. They could be present in forests and grasslands, along lakes and streams, if not in parks, lawns, and golf courses. These bites are painless, however they produce itchy, raised red lesions from the skin which can be just like the reaction from experience of poison ivy or oak. Scratching the bites can also cause them to spread and search as a rash.
