Termite swarmers appearing inside the house — San Francisco, California
Finding winged termites (swarmers) indoors — often near windows, light fixtures, or in spider webs — means an active colony is living inside or directly beneath the structure and has matured enough to produce reproductives. Unlike flying ants, termite swarmers have straight antennae, equal-length wings, and a thick waist. A pest-control technician identifies the species, locates mud tubes and colony access points using moisture meters and thermal imaging, applies targeted liquid termiticide or installs a baiting system, and schedules follow-up inspections to confirm elimination.
