This house was invaded by house flies, apparently intending to overwinter. We estimated this approximately 3000 square foot house had an average of at least 5 flies per square foot, giving a minimum total of 15,000 house flies.
The owner had passed away about two months prior (at a hospital, not here), and the house has been unoccupied. One of two roof-mounted swamp coolers was not sealed, and served as the point of entry. This house is on a large cattle ranch in the Chinese Camp area. The flies started coming in with the advent of cold weather in late October 2018. Ryan McQuoid of Foothill-Sierra Pest Control, Sonora California, did the service.
Service tech Ryan McQuoid and I did the video and treatment. October 30, 2018, Chinese Camp, Tuolumne County, California.
Garry Brouns collected these tiny subterranean termite alates from a house on Chumash Drive, Dorrington. This is our first report of what we think might be an undescribed high altitude subterranean termite. (CM 42313).
The body length is 1/8 inch.
The house, in the area these termites were found, had an oak floor, with damage to the subfloor.
