Nuisance and Biting Flies
Spaerocerid Fly Identification
On these flies, the first segment of the tarsi is enlarged compared to
the other segments. The tarsi are the last five segments of the legs.
Spaerocerid Biology and Habits
The Spaerocerid flies are also called "dung flies"because they may breed
in animal manure. Sphaerocerid flies belong to a large family of flies
known as Sphaeroceridae which contains 241 species in North America.
These fliea are very common in poultry houses breeding in chicken feces.
There are a few species that feed in any decaying organic matter, meaning
that they can be found in the same areas, such as Phorid
flies and Fruit flies. The biology and
habits are much the same as these other small flies.
Inspecting Spaerocerid Infestations
- Look for decaying or fermenting organic matter. Check
fruits and vegetables stored outside of refrigeration.
Trash containers or dumpsters which are not cleaned regularly might
be one such source. Inspect underneath and behind large appliances.
- Decaying organic matter may be trapped in cracks of
kitchen equipment (where it meets the floor). Because many food handling
establishments and food processing facilities use water hoses to wash
down the floor on a consistent basis, floor debris may be caught in
the small cracks and start to ferment.
Use a knife to scrape at the bottom on the equipment, to inspect the
debris and the presence of live larvae.
- Inspect floor drains. It may be breeding site, although
this fly is usually not found there.
The Drain fly, Phorid
fly , and Fruit Fly may also be breeding
there. These small flies : Sphaerocerid, Drain, Phorid, and Fruit Flies
are often found breeding in the super thin layer or film of debris that
naturally accumulates in pipes, traps and drains.
- Floor and sink drains can then be treated with bio drain gels such as Invade Bio Drain Treatment: Invade Bio Drain Treatment Gel.
Spaerocerid Fly Control
- Finding and removing all breeding sources of Spaaerocerid Flies is the first
and best method of elimination.
- Floor drains need to regularly cleaned, not only
for Spaerocerid Flies but the other small flies.
Bleach and hot water are not adequate to remove breeding sources. Floor and sink drains can be treated with bio drain gels such as Invade Bio Drain Treatment: Invade Bio Drain Treatment Gel , as a component of Integrated Pest Management.
If these flies are found breeding in crawlspaces or inside walls, the
breeding source needs to be removed and dried completely.
- After the breeding sources have been removed, you
may use a space spray (ULV) non-residual, pyrethrin
treatments to kill the remaining adult flies.
- We have pyrethrin and other fogging material
and foggers, as well as, hand held pyrethrin aerosols, such as CB 80, PT 565, V One or PI Contact Aerosols.
