How to get rid of this?.To get rid of pest problem under control, inspection is the first and foremost step.
BLOW FLIES
Color: Iridescent blue green or black
Size: 3/8-1/4 inch
Habits: Feed on animal carcasses and fecal material. Strong fliers. Black blow flies sometimes over winter in buildings even though no carcass is present.
Habitat: Animal carcasses indoors or out. May fly considerable distances to a breeding source. Maggots often migrate from the carcass when mature.
Threat: Can carry disease pathogens but the their relationship to health in man is not well understood.
Prevention: Screen them out. Locate and remove carcasses.
CLUSTER FLIES
Color: Dark gray with golden hairs
Size: Slightly larger than a house fly
Habits: Larvae live in earthworms. Adults over winter in buildings although more common in commercial buildings than residences. Occupants of buildings usually see them in late winter during first warm days when the flies begin to become active. Usually one generation per year.
Habitat: Larvae live in lawns and fields. Adults migrate a mile or more to over wintering site.
Threat: No threat to man
Prevention: To prevent over wintering, seal all tiny cracks and crevices on the exterior of the building – especially along the roof line.
DEER/GREENHEAD
Color: Brown to black. Some with green heads
Size: Up to 3/4 inch
Habits: Larvae live in stagnant water or moist soil. Adults are strong fliers. Females take blood meals. Active during summer months outdoors.
Habitat: Outdoor areas near water
Threat: No health threat but they have a vicious bite.
Prevention: Wear long sleeved clothing. Insect repellents are of some value. Use fans around pools and barbecues to create strong air currents which these flies do not like
DRAIN FLIES
Color: Dark gray
Size: 1/12-1/10 inch
Habits: Breed in slimy organic accumulations in drains and sewage plants. Not strong fliers. Wings have scales like moths. Adults rest on surface near breeding sites.
Habitat: Drains and sewer plants
Threat: Not documented but probable pathogen carrier
Prevention: Keep drains clean
FRUIT FLIES
Color: Tan with red or dark brown eyes
Size: 1/8 inch
Habits: Breed in decaying fruits and vegetable. Flies hove over food source or rest on walls near the source.
Habitat: Breed in moist decaying matter – especially if it has high sugar content. Often found in the bottom of trash cans after the plastic liner has ruptured.
Threat: Possible health concern but not documented.
Prevention: Discard spoiling fruits and vegetables. Wash out slimy residues in the bottom of trash receptacles.
FUNGUS GNAT
Color: Pale to dark brown
Size: 1/16 inch
Habits: Breed in wet, organic matter such as potting soil. Fly to lights. May be breeding in over-watered plants indoors or in roof structures if leaks have occurred.
Habitat: Wet, organic materials. Live indoors and outdoors
Threat: None
Prevention: Don’t over water plants. Repair leaks
HOUSE FLIES
Color: Dark gray
Size: 1/4 inch
Habits: They can only feed on liquids but they regurgitate on solid foods to liquefy them. Eggs are laid on wet organic matter in which the larvae (maggots) feed. They are active only during light hours.
Habitat: Live in wet, organic materials like garbage. Adults tend to rest on roof structures at night. They live outdoors during summer.
Threat: Flies are known to carry over 100 different pathogens and their habit of flying from sewage or garbage to our food makes them a real health threat.
Prevention: Screen windows and doors to keep them out. Keep garbage in tight-fitting covered containers. Clean out garbage cans weekly.
PHORID FLIES
Color: Tan to brown
Size: 1/8 inch
Habits: Breed in a variety of plant and animal matter. Some a pest in mushroom farms. Some pests in mausoleums. Indoors they are often a sign of a broken waste line and they breed in the contaminated soil beneath the slab. Adults look like fruit flies but tend to skip across surfaces
Habitat: Wet, organic matter of various types.
Threat: Possible pathogen carriers considering the breeding source.
Prevention: Eliminate breeding sources. In the case of broken waste lines, the slab must be opened and all contaminated soil removed.
FLIES
PEST CONTROLThe house fly has a gray thorax with 4 dark, longitudinal stripes.There are so many devices to kill the flies.
Flypaper (also known as fly paper, fly sticker, fly strip, fly ribbon, or fly tape) attracts flies to sticky adhesive so that they can be trapped.Electric flyswatter are hand-held devices that resemble badminton rackets or tennis rackets, which became popular worldwide in the late 1990s.[citation needed] US Patent 5,519,963 was awarded to Taiwanese inventor Tsao-i Shih in 1996 for such a device.
