Ever since the first winged insect lifted itself off the ground 300 millions years
ago there has never been a more efficient distributor of disease.
Of the thousands of species of flies, only a few are common pests in and around the
home. Some of the more common nuisance flies are the house fly (Musca domestica),
the face fly (Musca autumnalis), the stable fly (Stomoxys calcitrans), the little
house fly (Fannia canicularis), and several species of garbage fly (especially in
the genus Phaenicia).
These pests breed in animal wastes and decaying organic material from which they
can pick up bacteria and viruses that may cause human diseases. In addition, adult
stable flies (sometimes called "biting flies") feed on mammalian blood and can give
a painful bite.
While humans commonly find adult flies to be the most bothersome, the larval stage
should be the prime target for control efforts. Elimination of larval habitat is
the preferred method of pest fly suppression.
By removing material in which the larvae develop, the life cycle of the fly can be
broken, preventing subsequent production of adult flies.
While chemical pesticides may be effective for suppressing adult fly populations
in some situations, they are not a substitute for proper sanitation and aggressive
elimination of nuisance fly developmental sites. Because flies can quickly develop
resistance to insecticides, use them only as a last resort to obtain immediate control
of adult flies.
