I live in Las Vegas and had a swarm of flying ants or termites appear inside the addition of my house. They must have come out of the wall or baseboard trim. They numbered over a hundred. Based on photos with slightly lower resolution than what I posted here, a local pest control company told me I had swarming red harvester ants (another company told me I am dealing with drywood termites and the only solution is to tent and fumigate my home, but they seemed to jump to that conclusion without examining anything). The swarmers appeared in early August after a storm. But when I examine a single alate, it seems to have the classic features of a termite: four equal sized wings and no apparent waist in the body. They look similar to photos of subterranean termites that I find online. Is it possible to tell the difference based on photos?
