How do you identify the different types of flies?

Houseflies, or Musca domestica, come from the order of insects referred to as Diptera.  Mosquitoes are also included in this insect species.  These tiny flies all over house are often described as “filth” or “nuisance” flies. They not only bother us, but they also spread germs and bacteria.

Anywhere humans live, you will find these flying bugs. They will breed and feed on the feces of animals, trash, and organic rotting matter. After they feed on this stuff, they fly indoors, landing on surfaces for food preparation and food sources. Spreading disease and bacteria everywhere they tread. They are also attracted to and known to land inside sweet-flavored drinks.

The worse part is where houseflies feed. They actually regurgitate what’s inside the stomach to soften and liquefy it. They will also defecate on surfaces and food items they land on to cause further contamination.

“True flies”, one of the largest insect groups, is what the Diptera order of insects is comprised of.  One can recognize the Diptera species by their wings. They have a single set of two wings. This is in comparison to other fly species. Who only has two pairs of wings.

Filth flies may be placed in two categories. These groups are based on their preference for food and appearance. Species such as the Blowfly, Fleshfly, and Housefly have eyes that are recognizably larger than their small size. In addition, Fruit flies, Phorid flies, Drain flies, and others have bodies significantly smaller.

  • Sources of sustenance: Flies will eat whatever they find to sustain themselves. They are not picky eaters. As long as your home provides them with constant food sources, they will continue to breed and buzz around.

Ways to Take Control

Below are some tips for how to take control of a fly problem and where flies lay eggs and reproduce:

  • Ensure all garbage cans have lids that close and seal tightly. Also, take out the trash and have it emptied regularly, particularly if there is old food in it.
  • Make sure to keep any indoor compost containers tightly sealed, and also clean them every time you dump them.
  • You need to remove cat feces from the litter box daily, as well as clean the entire box weekly.
  • Keep dirty dishes out of the sink, and don’t leave any food uncovered on the counters.
  • Make sure the dishwasher door is always closed tight, particularly if you only run it every few days. In addition, in the hotter months of summer, run the dishwasher more often since this is when flies are more rampant.
  • Take periodic walks around your property to verify there is nothing flies are attracted to, such as dead animal carcasses lying about.
  • When cleaning out the refrigerator of old food, do so the day prior to weekly trash pick-up. This ensures flies will not be attracted to spoiled food lying in the hot trash cans.
