Termites and ants are similar in that both have winged “reproductives.” When you see a swarm, are they ants or termites?
To tell them apart, look at their body shape. The ant will have a very distinct neck and waist.
A termite body will be pretty much the same diameter from head to tail (like a cigar).
If the winged insect is more than 1/2 inch long and dark black, it is likely to be a reproductive carpenter ant.
