In the United States, chiggers are most common in the humidity of the Southeast and the Midwest. Chiggers thrive on warmth and moisture. Avoid walking through brush, tall grass, and weeds. Avoid marshes, swamps, and wooded habitats with rotting leaves and stick piles.  Chiggers often wait in the underbrush and low shrubs to attach to small animals, which are their natural hosts. Stay away from bushes and vines that might brush against your body and deposit chiggers.  Chiggers rarely move very far from the sites where they hatch, resulting in patches of chiggers in damp and warm areas. Avoid sitting or lying directly on the ground during the summer months.  Instead, bring a folding chair or blanket to spread beneath you. Avoid perching on stumps or logs. Instead, sit on an object that is dry and hot, such as a rock that is warm from the sun. Chiggers are most likely to bite in the afternoons of the spring and summer, when the ground temperature is between 77–86 °F (25–30 °C). They become inactive below 60 °F (15.6 °C), and die when the temperature drops below 42 °F (5.6 °C). During chigger season, plan outdoor excursions when the weather is cool or dry.
