Chiggers are the parasitic larvae of certain trombiculid mites.
What bites
The larval stage attaches to skin and feeds on tissue fluids. Later stages are generally free-living.
Common misconception
Chiggers do not remain burrowed inside human skin after feeding.
Symptoms
Intensely itchy bumps may appear after exposure in suitable outdoor habitat.
Care
Avoid scratching, wash exposed clothing, and seek medical advice for severe reactions, infection, or diagnostic uncertainty.
Frequently asked questions
What are acarines?
Acarines are mites and ticks traditionally grouped within Acari or Acarina.
Are acarines insects?
No. They are arachnids, related more closely to spiders and scorpions than to insects.
Do all acarines bite people?
No. Most species do not bite people; many are decomposers, predators, plant feeders, or associates of other organisms.
Are ticks mites?
Ticks are commonly treated as a specialized lineage within the broader acarine grouping.
How many legs do acarines have?
Adults and nymphs usually have eight legs, while many larvae have six.
Can acarines be beneficial?
Yes. Many decompose organic matter, regulate other arthropods, or serve as biological-control agents.
Can a photo identify a mite?
Sometimes only broadly. Many mites require microscopy and specialist examination.
Are household specks always mites?
No. Dust, fibers, insects, debris, and skin material are commonly mistaken for mites.
Should pesticides be applied without identification?
No. Confirm the organism and follow labeled, professional, or extension guidance.
