Drain Fly Identification

Moth flies (Drain flies )are small flies, about 1/8th inch. They are usually black, but may be brown. The key identifying trait for this fly is the unique pattern of veins in its wings.

Drain Flies are small flies. Drain Flies are also called moth flies, sewer flies or filter flies these true flies have bodies and wings covered with numerous hairs. If crushed they leave a powdery smudge.drain moth fly

The flies are commonly found around drains, but they should not be confused with the Fruit fly, Phorid fly, or Sphaerocierid fly which also infest drains.

Just because you may see a small fly or gnat type flying around in the kitchen, do not assume it is coming from the drains. Check all possible breeding sources to help identify the fly. Using a sanitation drain product like Invade Bio Gel would only work in they are breeding in the drains.

Understanding the different breeding sources for the different flies will help you in identifying and managing the respective flies. The other flies that are found around drains are: Fruit Flies, Phorid Flies and Sphaerocierid Flies.

Breeding Sources of Drain Flies, Fruit Flies, Phorid Flies and Sphaerocerid Flies:

Drain flies: Drain Flies breed in breed in drains, sewers, septic tanks and soil that has been contaminated with sewage.

Fruit flies: Fruit Flies can be spotted around fresh fruits/vegetables, rotting fruits and vegetables, drains, garbage and damp organic materials.

Phorid Flies : Phorid Flies are found in sewage contaminated soil, garbage, drains, human cadavers, rotting vegetables and fruit, garbage as well as damp organic materials.

Sphaerocerid Flies: These flies may be found in manure, damp organic material, drains, rotting fruits and vegetables and garbage.

Drain Fly Control and Treatment

It is necessary to inspect for breeding sites and remove them. Also look for potential breeding sites and eliminate those. There are many potential areas that serve as a breeding site, so this is the most difficult area of control. It is crucial to regularly clean floor drains. Bleach and hot water will not eliminate fly larvae breeding in a drain. Use Invade Bio products instead to eat the organic matter as part of an integrated pest control approach.

Inspect and Clean- Breeding Sites

 

  • These flies typically breed in drains, hence the common name of drain flies. This is a good place to begin inspection. They live off debris in the form of a humid film on the drain sides and in the drain trap. If you use something like a knife to scape the sides, you can examine live larvae.
  • Place some tape over the top of drain, with some holes in it for air flow. If the drain flies get stuck on the tape as they exit the drain, you know you have drain flies.
  • Sometimes, moth flies (drain flies)can come from under slab floors from a drain pipe that has broken. They would breed in the organic debis under the slab.
  • Adult flies then enter the living space above the slab through cracks in the slab and back through the drain pipe. To determine if they are coming up through the slab, place the masking tape over the crack as described above.
  • If the suspicion is strong enough that drain flies are breeding under a slab, a hole must be broken through the slab to see if indeed a pipe has broken and flies are breeding there. After a hole is broken through the slab, dig in the soil under the slab and inspect. The organic debris and moist soil may actually be several inches under the surface. The presence of fly larvae and/or adults confirms the site as a breeding source.
  • Sump pump pits and sewers are usually found in a basement area and also prime breeding sites for moth flies, particularly in commercial buildings. The sewers and pump pits need to be checked for activity even if it is not close to where the moth flies been seen flying. Also, inspect the pits of elevators in commercial buildings for excess water or moisture.
  • In homes, moth flies are generally found breeding in bathroom drains, particularly those in showers. Shower pans are prone to leaking and the area under the shower pan becomes a prime moth fly breeding source.
  • Remove all organic debris trapped in small cracks and crevices under the legs and bottom edges of kitchen equipment. The debris needs to removed, thoroughly dried and a long lasting caulk applied to seal the crack.
  • If you strongly believe that the shower is a possible source, it may be necessary to drill a hole into the area under the shower pan or the wall behind the shower. In most cases where moth flies are breeding in this area, adult flies will begin emerging from the hole within minutes. Drain flies are strongly attracted to light and will fly to the hole drilled through the wall.
  • Inspect crawlspace areas. Sometimes, if the drain pipe is leaking there, a breeding source is found. Look for the presence of adult flies. Spiders may have dead moth flies in their webs.
  • Don't stop looking when one breeding source has been found. In most cases, several breeding sources will be present.
  • Drain flies, or moth flies, can be found in moist, highly organic debris areas such as sink drains, moist mops, sewage treatment facilities, storm drains, dung and rotten vegetation.
  • Re-grouting tiles to prevent water seepage into walls will stop breeding in those sites. If found in rotting vegetable matter, the source should be destroyed.
  • Clean dirty garbage containers, wet lint under the washing machine, and even standing water in containers under houseplant pots. Outside the home, inspect air conditioners, bird baths, shallow stagnant pools of water and sewage treatment facilities upwind as adult flies will travel with the wind.
  • Drain flies may also breed in moist, shady areas outdoors such as under potted plants, in bird feeders and baths, in moss, in clogged roof gutters, under air conditioners, in thick mulch, or on wet ground areas.
  • In natural settings, moth fly larvae feed on decaying plants and animals. Most moth flies are harmless to humans, though they may transmit bacteria and other microorganisms from their breeding sites to areas where people are. Moth flies do not bite. Adults live about two weeks

Sanitation Treatments

Invade Bio Products invade bio invade bio foaminvade hot spot

Use Invade Bio Products in the drains. A use of a drain cleaner such as Invade Bio Gel Treatment will remove the organic debris, improving santitation.

Invade Bio Foam is another another type of Invade Bio product; particulary useful in commercial establishments. It is a concentrated bio liquid with the use of a foamer. Invade Bio Foam contains concentrated scum eating, odor eliminating microbes and foaming agent. Use this a part of an integrated pest management tool. Use 1 oz per quart, 4 oz per gallon. Apply using a Chapin Foamer or sprayer to cracks, crevices and drains where small flies breed. The foam and citrus combination will digest the organic debris present as part of pest management. Ultra-concentrated InVade Bio Foam is mixed with water at a rate of 4 oz per gallon (1 oz per quart) and applied using Foam Sprayers.

Invade Hot Spot is a Microbial/Citrus Foam in an easy-to-use 16 oz aerosol. Hot Spot is an aerosol can that contains the same premium microbes and ingredients as InVade Bio Foam. The 360 degree valve allows for foam dispensing in any orientation to easily hit hard-to-reach areas.

If adults do not disappear within a week further treatments or looking for other breeding sources is needed .

Use Contact Aerosols (Pyrethrins)

After breeding sources have been removed a space spray such a pyrethrins, a non residual insecticide can be applied to kill the adult flies. We also carry metered dispensers that use metered aerosols for commercial establishments.

 

 

 

 

Use Fly Lights

Another tool you could use would be insect light traps, but they attract mostly male Moth flies. There use involved with this type of fly would be limited except as a tool for monitoring.

 

Biology of Drain Flies

 Moth flies (Drain Flies) develop by complete metamorphosis. The entire life cycle ranges from 8 to 24 days.

Moth flies (Drain Flies)lay eggs in a mass of 30 to 100 in a suitable medium. These eggs hatch in less than 48 hours. The eggs form the moth fly( drain fly) are laid in irregular masses in such places as dirty garbage disposal units, water traps in plumbing fixtures, sewage plant filters and almost any where decmposing organic materials are found.

The larvae and pupae of the moth fly live in the thin gelatinous film found in drains, septic tank field lines or filter stones. The larvae feed on sediment, decaying vegetation and microscopic plants and animals. The larval stage lasts from 9 to 15 days before pupating.

The pupal stage lasts from 20 to 40 hours. The newly emerged adult fly is sexually mature on emergence and copulates within the first few hours of its life.

The moth fly (drain fly) is a poor flyer and may be commonly seen ealking or running on walls and other resting surfaces. When they fly in short jerky lines, they fly for only a few feet.

During the day the moth fly (drain fly) adult rests in shaded areas or on walls near plumbing fixtures or on the sides of tubs and showers. Most of the activity of the moth fly (drain fly) occurs during the evening. They may be seen hovering around the sink areas in your home at this time.
