​Flies go through full metamorphosis, which means they go through 4 stages of life: egg, larvae, pupae and adult. 


Bottle Flies:










Bottle flies (also known as blow flies) are metallic blue, green or black in colour.  They have an average life cycle of 6 weeks and a size of roughly 3/8 inch (8-10mm) which makes them slightly larger than a house fly.  They are common visitors to dead and decaying animal matter, feces and garbage.  Their eggs are about 1.5mm long, usually white or pale yellow.  The larvae are white to pale yellow as well, go through 3 molts and are approximately 1/2- 3/4 inch (13-19mm) long prior to pupation.  The pupae are in a hardened shell approx. 3/8 inch (9-10mm) long and are reddish brown to black in colour. 


Harm and Damage:

Due to the materials that they live/breed in, it is not uncommon for the bottle fly to transmit gastrointestinal diseases and intestinal parasitic worms.  They have also been implicated in the spread of other dangerous diseases. 

Cluster Fly:









​​

The adult cluster fly is slightly larger than a common house fly.  They are a dull grey with black markings.  Cluster flies are considered a beneficial fly due to the fact that they are pollinators.  Their eggs are laid in or around an earthworm hole or directly into the earthworm itself, where they parasite the earthworm.  There may be 3 to 4 cluster fly generations per season.  In the fall the last generation will seek out natural outdoor wintering sites, but can also over winter in many man-made structures.

Harm and Damage:


The cluster fly is basically a nuisance type pest.  They can collect in very large numbers in cracks and crevices of window frames, soffits and attics.  They will not damage your home but occasionally when populations are high, their feces can become an issue.  

Vinegar and Pomace Flies (commonly known as Fruit Flies):












Fruit flies are red eyed 1/4 inch long (10-12mm) and are attracted to overripe and fermenting fruits and vegetables.  They will reproduce in great numbers wherever they can find decaying organic matter.  This can even occur in drains etc.  The flies are also attracted to light and moisture.  The most effective way to control fruit flies is to eliminate breeding sites. 

Harm and Damage:

Fruit fly populations can increase quite rapidly and get out of control quickly.  Also due to the materials that they live/breed in, it is not uncommon for the fruit fly to transfer bacteria leading to gastrointestinal diseases and other potential health problems.
