Non-biting flies, such as houseflies, are not only nuisance pests, but they are also responsible for transmitting diseases and contaminating food.
For instance, house flies are capable of contaminating food and transferring more than 100 pathogens, including malaria, salmonella and tuberculosis. Food contamination is one of the main reasons that fly pest control is so important.
Fruit fly adults are small, yellowish or brown flies with red eyes, about 3 mm long. Larvae are small, white, legless maggots that may grow up to 5 mm long.
Adult fruit flies are attracted to overripe, fermenting fruit of all kinds. Larvae, or maggots, feed on the fruit and may spread yeasts that cause souring.
Their name comes from the fact that they are the most common fly found in homes. Adult flies grow up to one quarter of 2.5 cm long, with a life span of between 15 to 25 days.
Under favorable conditions house flies can reproduce prodigiously because of their rapid developmental time and the large number of eggs produced by each female—several batches of about 100 to 150 eggs. Eggs are laid in warm, moist, organic materials such as manure, garbage, lawn clippings, decaying vegetables and fruits, or soils contaminated with any of these materials. Larvae of the house fly are cream colored, have a blunt posterior end and taper to a point at the head. Young larvae respond negatively to light and will burrow into the organic material in which they are developing. Older larvae respond positively to light and will emerge from their organic habitat to seek drier and cooler areas to transform into pupae. Under optimal summertime conditions, house flies can complete their development from egg to adult in as little as 7 days
Drain Flies are also called moth flies, sewer flies or filter flies and they are a common pest in the UAE. Their bodies and wings are covered with numerous hairs. If crushed they leave a powdery smudge. The flies are commonly found around drains, but they should not be confused with the Fruit fly, Phorid fly, or Sphaerocerid fly which also infest drains.
Drain Flies breed in drains, sewers, septic tanks and soil that has been contaminated with sewage.
In homes, adults are found on bathroom, kitchen or basement walls. More active at night, drain flies do not bite and, surprisingly, do not transmit human diseases. Drain flies feed on organic matter and sewage.
The best way to control drain flies is to try to remove their breeding site, which is most case will be organic materials collected in the drain, those organic material must be removed physically if possbile to reach and treated well, and the adults will stay without a place to breed and left to die in few days.
