Flies

House FliesHouse Flies

In the summer months household flies seem to be every where. They are seen inside buildings, around picnic tables, lunch areas, anywhere we gather and there is food.

What to look for

Household flies suck liquids containing sweet or decaying substances. Larva feed on moist food rich in organic matter. In the summer months they are found outside in garbage, manure, anywhere there is decaying matter. The key to controlling flies is to remove organic matter, ensure general sanitation is good, and to ensure screen doors are in place to keep all pests out.

How to identify a house fly

The female lays 5-6 batches of 75-120 white eggs on moist manure or garbage. Eggs hatch in 10-24 hours. Larvae reach full size in 5 days emerging as adults about 5 days later. Males live for 15 days, females up to 26 if they have access to milk, sugar, and water. Household flies can transmit typhoid fever, cholera, dysentery, pinworms, hookworms, and some tapeworms. House Flies are regarded as a greater threat to human health than most other insects.

Cluster FliesFlies

Cluster flies are annoying and frustrating to eliminate because there is no easy answer to how to get rid of them.

The problem is that female cluster flies lay their eggs in soil but once the larvae hatch they burrow inside earthworms which then serve as a food source to the developing maggot. After a month or so the maggot develops into a full blown fly. The only way to get rid of the maggot is to get rid of the earthworm host. But earthworms are so beneficial to the garden that to get rid of them would be environmentally unsound. Each year, beginning in spring, up to four generations of cluster flies may emerge from your soil.

What to look for

Typically, as the cool fall days approach, cluster flies gather together on the south and west sides of a building, often close to windows and door frames, preparing to hibernate in gaps in the side of the structure. They particularly like to pass the winter in the voids in older frame buildings and other sheltered areas such as behind curtains, under shelves, dark corners, etc.

On warm winter days or as spring approaches the cluster flies emerge and crawl across walls and windows, becoming more active as they warm up. They are attracted to light so you may find collections of dead cluster flies lying beneath a left-on light bulb in an attic or shed, for example.

How to identify a Cluster Fly

Cluster flies are a medium size fly 1/4 to 3/8 inch in size. They are dark in colour, have golden yellow hairs on the front part of the thorax. When at rest the wings are held flat over their backs. When crushed they give off an odour of buckwheat honey.

What we can do to help

Peregrine’s skilled technicians are trained in eliminating existing cluster fly populations. A chemical application in the fall done before the flies move indoors will greatly reduce the overall cluster fly population. They will also identify and seal possible future entry points and will apply special repellent products to prevent future infestations.


Small Flies flies

Indoors, the types of small flies that appear are fruit flies, moth flies, and phorid flies. These flies are problematic in food establishments where cleaning is optional. They can be found in floor drains, under broken floor tiles, garbage bins, grease bins, pop holder dispensers, under cooking equipment and other areas.

What to look for

The environment small flies prefer is a warm, moist environment with plenty of food. Food builds up in cracks and crevices. Many times food is pushed down floor drains in the process of washing floors. The organic matter, builds up over time, creating a perfect breeding ground for small flies.

A regular cleaning program is required to to take away the food source of small flies. This includes the hard to reach areas under counters and equipment. By removing the food source you break the cycle of the small fly.

How to identify small flies

Fruit flies are a small fly 1/8 inch in size. The head and thorax are tan coloured. A key feature are bright red eyes. An obvious source to check are fruits and vegetables stored outside of a refrigerator.

Phorid flies are a small fly 1/8 inch in size. They are tan to dark in colour. The thorax is humpbacked. The wings have two dark veins. Adult phorid flies run rapidly along surfaces. Larvae can only survive in moist decaying organic matter. Check floor drains and other drains.

Moth flies are 3/16 inch in size. They are brown to grey or grey-black in colour. The body and wings are covered with tiny hairs. Moth flies typically breed in drains.
