The fruit fly and the phorid fly are both little flies. They are often mistaken for one another despite being members of two distinct fly families. Although they have roughly comparable appearances and are about 1/8 in length, their biology and care differ greatly. Both phorid flies and drain fly/moth flies are frequently seen in drains.
You can better identify and control the different flies if you are aware of their different breeding sources. Fruit flies, drain flies, and sphaerocerid flies are the other types of flies that are found around drains. See details here about how to prevent these pests from entering your house.
Ways to prevent phorid fly issues below the slab
It is important to settle the details of relocating furniture and appliances before anyone puts carpet to concrete. It is important to determine as precisely as possible the locations of any utilities, including power lines, that might be in or beneath the slab. The actual locations of pipes and wires frequently differ significantly from the designs. The facility’s engineering staff or a qualified mechanical contractor should carry out the actual floor deconstruction and fill removal. Unanticipated incidents and problems often require the kind of on-site modification that should be performed by a skilled contractor.
Concrete, rebar , and soiled fill will require cleaning. By far the best approach is to use vacuum trucks to remove the contaminated fill and concrete saws to cut out the concrete. State and local laws may apply, and the fill may need to be removed in advance. You will need to remain on site while the restoration takes place and for the opening. Some vital hints and data will only be available for a limited time. Inspect for pupae and larvae periodically. It can be tough, but every now and then, you find the telltale but tiny hints of “pay dirt.”
When entrenched in the dark, soupy matrix of decay, the larvae, which usually appear beneath the pipe, can be difficult to identify. It might be necessary to wait for the maggots to move when using high-quality lighting and the low-angle strategy. Put on gloves, coveralls, and sturdy work boots. Although some people prefer disposable nitrile gloves, the best gloves are thick, reliable, reusable, washable, and sanitized.
If you decide to use disposable gloves, make sure they are at least five millimeters thick and be ready to replace them often because sharp things can rip them. Dangerous environmental diseases may be present if the issue involves sewage.
Preventing phorid flies
-
Locating their nesting sites
The most challenging part of managing phorid flies is finding their nesting sites; yet, eliminating them is the only effective long-term remedy. Keep in mind that the larvae can only live in damp, decaying organic materials when looking for breeding sites. Adult Phorid flies can be found in a number of places, but they are most common among decomposing plant and animal materials.
-
Check every location
Look for these insects in various locations. Plumbing leaks can result in damp areas with mold or fungal growth, so check the drains and plumbing in the kitchen and bathroom areas, as well as the garbage cans, garbage disposals, crawl spaces, wall voids, and basements. Furthermore, inspect the condensation drop pans under refrigerators and the damp mop closets.

Examine the decomposing animal and plant materials.
Sometimes the answer is as easy as cleaning a drain or discarding a piece of decaying fruit that was found beneath the stove.

Remove the organic matter film
Fly larvae growing in a drain will not be eradicated by bleach or hot water. The larvae reside in the organic matter film that lines the sewer. The larvae must be killed or removed by removing this film. This film can be removed with a brush and a solution of mild bleach. The drain can then be completely cleaned with water. Initial drain cleaning can be a dirty task, but repeat cleanings will be much easier.
