Carpenter ant bites in Maine: what the mark looks like
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 — all of which are also recorded in Maine.

Carpenter ant season in Maine specifically
Records in Maine 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 Maine runs May to October.
Because damp or decayed wood — decking, window frames, tree stumps, exposure in Maine 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.

How Maine compares
Across the 47 states with any carpenter ant records, Maine ranks 26th with 336. The state directly above it is Iowa (361). Directly below is Vermont (335). The highest count anywhere is New York (2,806).
Inside Maine itself the picture is different again: of the 15 biting species we track with records here, this one is 4th and accounts for 10% of the 3,226 records logged in the state. A species can be common nationally and marginal in one state, or the reverse — which is the whole reason this page exists separately from the national guide.
