Identifying it in North Carolina

A carpenter ant bite is a mechanical pinch from large jaws, occasionally with formic acid sprayed into the wound, which stings briefly. There is no sting apparatus and no pustule — that is what separates it from a fire ant.

Locally, the species most often confused with it are honey bee sting, fire ant sting, bald-faced hornet sting — all of which are also recorded in North Carolina.

Season in North Carolina specifically

Records in North Carolina concentrate in April, May, June, August, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in North Carolina runs March to November.

Because damp or decayed wood — decking, window frames, tree stumps, exposure in North Carolina 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

  1. wash with soap and water
  2. cold pack if sore
