Identifying it in Rhode Island

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, bald-faced hornet sting, paper wasp sting — all of which are also recorded in Rhode Island.

Seek medical care if

Call emergency services now for difficulty breathing, swelling of the lips, tongue or throat, dizziness or fainting, or hives spreading away from the bite.

Season in Rhode Island specifically

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

Because damp or decayed wood — decking, window frames, tree stumps, exposure in Rhode Island 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
