Where Do Chiggers Actually Live in the US?
Chiggers live in 21 US states and are confirmed absent from 10 more, based on 5,952 verified iNaturalist and GBIF records. This page covers every state at once instead of one near-identical page per state.
By Tim, founder of Easy Street Markets. I maintain the wildlife database and verify every animal and source myself.
The states with the strongest confirmed populations are Arizona, Arkansas, California, Georgia, Illinois and Iowa, and 15 more. These are real, verified iNaturalist and GBIF occurrence records, not modeled range estimates.
Chiggers have zero confirmed wild sightings in Connecticut, Delaware, Hawaii, Idaho, Massachusetts, Mississippi, New Hampshire, North Dakota, Vermont and Wyoming, despite tens of thousands of nationwide observation records for the species. That is a real, checked absence, not a missing page.
A small number of states (18) have only a handful of unverified or vagrant records, too few to confirm chiggers as an established population there.
