University of Arizona Cooperative ExtensionWhen chiggers are busiest in Arizona
UA Extension reports Arizona chigger encounters typically in late summer or early fall, when vegetation growth peaks; eggs are laid in soil in spring and larvae hatch later in the year.
UA Extension says it is nearly impossible in Arizona to recognize and avoid chigger-infested areas, and recommends long sleeves and pants, high-top boots with pants tucked in, repellent at clothing openings, and a hot soapy shower on returning home.
