Chigger
Chigger
Chigger (/ˈCHiɡər/), also known as Harvest mite, Berry bug, or Red bug, is a type of parasitic mite that belongs to the family Trombiculidae. The term "chigger" is derived from the Choctaw word "chike", which means "flea".
Description
Chiggers are tiny, red mites that are barely visible to the naked eye. They are known for their itchy bites, which are caused by the larvae feeding on the skin of warm-blooded animals, including humans. The adult mites are harmless and feed on plant material.
Life Cycle
The life cycle of a chigger consists of four stages: egg, larva, nymph, and adult. The larvae are the only stage that feeds on animals. After feeding, the larvae drop off the host and transform into nymphs, which then mature into adults.
Habitat
Chiggers are found worldwide, but they are most common in areas with tall grasses, weeds, and other dense vegetation. They are especially prevalent in humid and warm climates.
Prevention and Treatment
Prevention of chigger bites involves avoiding infested areas, wearing protective clothing, and using insect repellent. Treatment for bites includes over-the-counter creams and ointments to relieve itching and inflammation.
