Scabies bites in Indiana
Indiana has 90 verified scabies records in the GBIF biodiversity database — one of the highest counts in the country. Sightings concentrate in July. The bite itself appears 2 to 6 weeks after first exposure; within days on re-exposure and lasts until treated — it does not resolve on its own.

Identifying it in Indiana
Scabies is not really a bite — it is an infestation of the skin's surface layer, and the pattern is what identifies it: symmetrical, in skin folds, worst at night, and shared by more than one person in the household. The short grey burrow lines between fingers are the specific finding when they can be seen.
Locally, the species most often confused with it are mosquito bite, honey bee sting, bald-faced hornet sting — all of which are also recorded in Indiana.
Seek medical care if
- itch that keeps the whole household awake
- crusted, thickened skin — a severe form that is highly contagious
- weeping, crusting or fever from scratched skin
What else it could be in Indiana
These are recorded in Indiana too and are the ones most often confused with it here. The differences below are the ones that actually separate them.
| Scabies rash | Bed bug bite | Flea bite | Chigger bite | |
|---|---|---|---|---|
| Pattern | symmetrical, in finger webs, wrists, waistline, armpits and groin | lines or zigzags of three or more — the classic "breakfast, lunch and dinner" | clusters of three or four, or short irregular groups | clusters concentrated where clothing is tight |
| Where on body | finger webs, wrists, elbows | arms, shoulders, neck | ankles, shins, behind the knees | ankles, behind the knees, waistband |
| Appears | 2 to 6 weeks after first exposure; within days on re-exposure | hours to several days — many people notice nothing on the first night | immediately to within an hour | 3 to 6 hours after exposure — never immediate |
| Records here | 90 | 36 | 24 | 7 |
Season in Indiana specifically
Records in Indiana concentrate in July, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Indiana runs April to October.
Because transmitted by prolonged skin-to-skin contact — households, care homes, sexual contact, exposure in Indiana tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.
Care

- treat every household member at the same time, symptoms or not
- wash bedding and clothing at 60°C and tumble dry; seal what cannot be washed for 72 hours
Avoiding them in Indiana
- treat contacts simultaneously
- avoid sharing bedding and towels during treatment
