Flies
What are the flies that bug me the most in my home?
   Blow Flies
Facts, Identification & Control
Appearance
Blow flies are often metallic in appearance, with feathery hairs on the terminal antennal segments of the males. Adult blow flies have sponge-like mouth parts, while maggots have hook-like mouth parts.

Behaviour, Diet & Habits
Blow flies are attracted to decaying meat and are typically the first organisms to come into contact with dead animals. The meat of dead animals is essential for larval survival and growth.
Blow fly maggots are generally seen near dead animals. Blow fly eggs are laid in rotting meat, where
maggots feed and complete their development before seeking a dry location within which to pupate.
After maturing, larvae create outer skins, known as puparia, that look like rat droppings or cockroach
egg cases. Pupae develop within the puparium, maturing into adult blowflies.

Larvae or Maggots

Where do you find maggots?
Female blow flies typically lay their eggs on decaying meat, where maggots hatch within a few hours
to a few days depending on species. These maggots undergo three stages within several days, after
which they leave their food source and pupate in soil. Within a few days, the pupation will be complete,
at which point they emerge as adults.

Appearance of maggots
Blow fly larvae are also known as maggots. Measuring 9 to 22 mm in length, maggots are equipped with
hook-like mouthparts and spiracles for breathing. They are soft and pale in colour and appear similar to
worms or grains of rice. Each body segment of the blow fly maggot has a median row of fleshy tubercles
that resemble hair.

Signs of a Blow Fly Infestation
The most common signs of blow flies are either the adults themselves or their larvae.  The adults may be
seen resting on surfaces or buzzing around potential food or odour sources. The larvae may be observed
when they crawl out of the breeding material to pupate.  Your BEST CHOICE will be to contact

Life Cycle of Blow Fly
   House Flies
Facts, Identification & Control
Appearance
Usually grey, less than 4 to 7.5 mm long with four black stripes on the thorax.

Behaviour, Diet & Habits
They prefer corners and edges or thin objects to rest on. Indoors, they rest on floors, walls and ceilings during the day. Outdoors, they will rest on plants, the ground, fence wires, garbage cans, etc. Night resting places are usually near sources of food and 5 to 15 feet off the ground.
Wide variety of food, including human food, animal food and carcasses, garbage and excrement.

Reproduction and life span
House fly eggs are laid in almost any warm, moist material that will supply suitable food for the larvae. The female may lay a total of five to six batches of 75 to 100 eggs. In warm weather, eggs hatch in 12 to 24 hours. The average life span for a house fly is less than 1 month.

Signs of a House Fly Infestation
The adult flies are the most common sign of activity. Larvae also may be seen as they crawl out the breeding material to pupate. Lastly, the pupae themselves may sometimes be observed nearby the breeding material.

House flies are major carriers of disease!
They are known to transfer over 100 pathogens resulting in ailments, including typhoid, tuberculosis, cholera and dysentery. House flies collect these pathogens on their legs and mouths when feeding on faeces, trash and other decaying material. It is therefore very important to get rid of your fly infestation. Your BEST CHOICE will be to contact

Where do house flies lay their eggs?
It is very important to identify the places where the flies have been depositing their eggs. It may be something simple like an uncovered trash can or a bowl of pet food on the patio. However the house fly breeding site could be something that is not obvious. The breeding site must be cleaned up or removed. If the breeding site is not removed, the flies will continue to be a problem.
