Flies - Spokane Pest Control



Adult House Flies are between 1/4 and 1/2 an inch long with a gray body, punctuated by four dark lines running along its length. Both males and females have a small amount of yellow underneath the thorax, one pair of wings and red eyes. Females can produce around 500 eggs in several batches of 75 to 150 at a time and within one day the larvae hatch from these eggs to feed. The most common flies in the Northwest are: fruit flies, drain flies, fungus gnats and cluster flies.


Flies are known to be dangerous as carriers of pathogens and diseases such as:

  • Typhoid
  • Cholera
  • Bacillary Dysentery
  • Campylobacter and E. coli
  • Diarrhea
  • Tapeworms

Disease is usually spread when House Flies feed and lay their eggs on garbage and rotting material, then land on human foods and food preparation areas, contaminating them.


Getting rid of House Flies can be a difficult and unpleasant task as unless the source of the infestation can be pinpointed, killing House Flies will simply not remove the infestation but will allow the remaining flies to go on reproducing.

It is important to track down and eliminate the source of the infestation. Getting rid of the nesting/ breeding ground of the fly is key and any type of garbage or organic material is prime fodder for the fly.

Homeowner Tip

Minimize the risk to your home by ensuring garbage is properly bagged and disposed of, all food is kept in air-tight containers, food preparation areas are kept clean and tidy, and areas of moist and rotting organic matter are removed from properties.

Check your window and door screens on a seasonal basis and repair holes and tears.
