Identifying it in Louisiana
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, horsefly bite — all of which are also recorded in Louisiana.

Season in Louisiana specifically
Records in Louisiana concentrate in March, April, July, August, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Louisiana runs February to December.
Because damp or decayed wood — decking, window frames, tree stumps, exposure in Louisiana 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
- wash with soap and water
- cold pack if sore
Avoiding them in Louisiana
- fix damp wood and leaks around the house
- keep firewood away from walls
