Flies 101: The different Types of Flies and What Threats they Pose to Your Troy, IL Home


Flies are one of the most common pests in the entire world. They have around 120,000 different kinds of flies that can be found across the globe. For North America however, we have around 18,000 different types, which is still a large amount! Flies have a short lifespan; however, this doesn’t prevent them from quickly reproducing in large numbers. When they reproduce, they also increase the spread of diseases such as tuberculosis, salmonella, and even malaria.


Where do these flies even come from?

Files usually hatch outside, and then eventually make their way into your Troy, IL home. These pests find their way into your home through weak spots in the structure such as torn screens on windows and doors or damaged weather stripping.  Outside of the home, these flies can lay their eggs in excrement, compost piles, garbage cans, and other rotting organic materials. On average female flies can lay between 75 to 150 eggs at a time, which if compressed together is around the size of a pea. This makes them extremely difficult to properly identify.

Houseflies are the most common pest as they produce quickly and in large numbers. They are known to move up to 20 miles from where they were hatched but can typically stay within a mile of their birthplace. Fruit flies, which are another common type of fly, can be found within the home. This is because they are attracted to food waste like rotten or overripe produce. They typically enter your home on produce or other food being brought into your home. Horseflies are not found indoors but usually are found outside. However, they can accidentally enter your home through open doors and windows.

Different Types of Flies Commonly Found in Troy, IL.

House Fly

The house fly is the most widespread type of fly that can be found within your home. They are typically identified as being gray in color and have four black stripes on their thorax. They have slightly hairy bodies with red eyes that contain thousands of small individual lenses. These pests also do not have stingers or teeth, so they cannot harm you.

These pests have a life cycle that is in four phases. It begins when a fertilized female fly finds a location to lay her eggs. These eggs look like small grains of rice. Usually, they lay their eggs in locations that have rotting meant, garbage, or food. These house flies only mate once, however, are capable of producing between 350-900 eggs in their lifetime. From this step, they then become larvae which are commonly known as maggots. These legless larvae feed at the egg-laying site for around three to five days. At the end of this period, the maggots seek out a dry, cool, and dark environment to develop in. From this point, they become adult house flies, which typically live for only 15-25 days.

These pests, even though they do not bite or sting can still cause problems for your family. They are able to transfer many different diseases and pathogens including tuberculosis, typhoid, and salmonellosis. These become dangerous because flies can contaminate food surfaces with these pathogens and other germs.

Fruit Fly

Similar to the House Fly, Fruit Flies are found all over the United States and can be found indoors year-round. These pests have a life span of around 25 days and are able to rapidly reproduce. Visually, they appear to be brown or tan in color, and they usually have red eyes. These types of flies are commonly found around rotting food, especially vegetables, and fruits, and even liquids such as wine, beer, and liquor. They are also attracted to and sometimes breed in moist, dark, and unsanitary environments. On average they lay around 500 eggs and they can hatch within as little as 24 hours. The contaminated food is another thing these pests share with their previous counterpart.


Fly Prevention

The best way to prevent flies from being in your home is with deep sanitation. This includes removing trash daily, ensuring counters and other surfaces are clean, and checking all windows and screens. Also removing decaying food matter will help immensely as well.
