The story that we’re excerpting below concerns the invasion of a neighborhood in Bryan, Texas by dreaded filter flies, aka drain flies, sewer flies, moth flies. A swarm of flies that bred in Bryan’s wastewater treatment facility has led the city to shut down a part of the system, prompting complaints as the insects quickly spread into the nearby neighborhood. The Dreaded Filter FlyThe facility is near a residential area that includes Royal Oaks Gardens apartments, where the flies can be seen coating walls inside some apartments. Shannon Wolfert, who lives at the complex off Carter Creek Parkway, said she started noticing flies about three weeks ago, and estimates she’s had about 400 flies inside her apartment. Jurica said the city has received complaints in a two- to three-block radius from the wastewater treatment facility, and they are hoping the flies will be mostly gone next week.
Flies in the genus Musca (family Muscidae) have long been known as transmitters of filth and disease. The adult black flies emerge from the cocoons and rise quickly to the surface of the water. Larval sampling for black flies involves lifting and examining stones and other objects from the stream. Indoor pests, such as the phorids, filter flies, fungus gnats and fruit flies, also can be controlled by sanitation measures, repair and cleaning of pipes and drains, and reduction of moisture levels in potted plants and other breeding sites.
However, because flies have become resistant to most insecticides, this method is now seldom practiced.


After chlorine and fogging sprays failed to kill them fast enough, city officials were forced to turn off the filter. While the filter is a cost-efficient way for the city to strip organisms from the water, its humidity and water also is a perfect breeding ground for the moth flies. They prefer standing and stale water, sewage, garbage and decomposing organic matter, which can collect in drains. Most species of flies lay eggs, but a few species, such as flesh flies (Sarcophagidae), retain the eggs in the body and give birth to larvae.
Larvae of most flies are thin-skinned, legless, cylindrically tapered maggots with a pair of mouth hooks at the tapered end and a pair of breathing spiracles at the blunt end. These insects are tiny, but very aggravating biters sometimes called "no-see-ums," "punkies" or "salt marsh sand flies." Belonging to the genera Culicoides and Leptoconops, they breed in intermittently inundated fresh, brackish and saltwater habitats or in moist soil, often associated with specific marsh or pasture grasses. Window and door screens are the most effective fly exclusion method, although occasionally tiny flies, such as fungus gnats, will pass through 16-mesh window screens. Flies alighting on surfaces treated with residual sprays either absorb the toxicant through the tarsi (feet) or ingest it with their mouthparts. Black flies are highly susceptible to biorational formulations consisting of dead bacteria. Water companies, Environmental Health Departments and the general public are aware of the misery which can be caused by a filter fly nuisance but the range of techniques for their control is not well known and has been haphazard.


Because of the large number of pests in this group, flies are often referred to by family name, for example, Tabanidae for horse flies or Calliphoridae for blow flies. Many flies have lapping-sponging mouthparts that require all solid food to be liquefied before ingestion.
When applied to the streams where black flies breed, their filter-feeding behavior effectively captures particles containing the bacterial spores that contain toxins specific for Diptera. Such selectivity causes many females to oviposit at the same site, for example, many filth flies oviposit preferentially on manure.
It is usually this fly that is referred to when complainants claim that hordes of flies appear on their window screens while they are cooking.
Adult flesh flies are grayish with black stripes running the length of the top surface of the thorax.
Flesh flies found in the home may have been attracted to odors of decay or were simply seeking shelter.
