Flies - Pest Control - Bayer
Species category: Flying pest
Scientific name: Musca Domestica

There are 2 different species:
  1. Musca domestica (Common Housefly) 
  2. Fannia canicularis (Lesser Housefly)

6-12mm in length, the common housefly is predominately grey whilst the lesser housefly is grey with an extensive yellow patch at the base of the abdomen.

Originally a native of temperate regions, the housefly is now common all across the world.

Both types of fly are highly active indoors. Lesser houseflies can tolerate cool climates and are frequently encountered in poultry houses. Both are happiest in warm climates, where they easily locate decaying food to hatch eggs. In cooler conditions, flies struggle, becoming less active, leading to a reduced development rate.

Common houseflies have a flight range of at least 8Km. They are highly active indoors, particularly in daylight and rest at night. They require constant food to maintain energy levels and favour a sugary diet, excreting faeces everywhere.

A fly only ingests liquid food and releases saliva on food as it lands. The saliva instantly pre-digests food to soak it up through its spongy mouth. They thrive in dirty areas, on exposed food or in waste bins which are quickly located in warm weather thanks to the intense odour.


More than a dirty nuisance, flies are known carriers of a wide variety of pathogens that can be passed to humans causing diseases such as:
  • Typhoid, 
  • Dysentery 
  • Diarrhoea….the list is extensive. 

They constantly excrete faeces and also vomit partially digested food, contaminating surfaces and food where they land, this leads to further disease risks.

Envu recommends Aqua K-Othrine Space Spray and Suspend Flexx Insecticide.
