Humpback Fly Information


Humpback flies are very small, and are sometimes confused with a Fruit fly.  They are approximately 1/8” long and they are dark in color (black or very dark brown).  The Humpback fly gets its’ name from its’ unusual shape, which is a head that is very small, and a large, arched thorax, that makes the fly appear to have a significant hump.

Location and Behavior Patterns:

Humpback flies can be seen throughout Florida all year long.  They are attracted to moist, decaying matter, such as; dead animals, garbage, or feces.  Inside a home, they can create a real problem, because they may breed inside plumbing lines, and can be very difficult to get rid of, without professional assistance.  Also, if there are many Humpback flies present, they may be a sign that you have a dead animal or rodent, somewhere in or around your home.

This type of fly is sometimes called a “scurry fly”, because they seem to scurry across the surface of counters or floors sometimes, instead of taking flight.


If you see Humpback flies, then all surfaces that they have come into contact with should be cleaned thoroughly, because they carry many germs and bacteria that may cause diseases in people.  If you suspect a problem of Humpback flies in your home’s plumbing system, then professional assistance is probably needed, in order to get rid of them completely.
