Thousands of house flies invade home

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.
