With warmer weather around the corner, Orkin Canada is prepared for the pests that come with the warmer weather and melting snow. Everyone is looking forward to flowers blooming, birds chirping, and flies coming in through the open door. Oh wait, not that last one! Flies are a nuisance that no one likes buzzing around inside their home or business.

There are many different species of flies; however, they all can cause a threat to your peace of mind, while some are a threat to your health and wellbeing inside your home or business. Whether its cluster flies, house flies, or fruit flies, at Orkin Canada we have 70+ years of expert advice on how to get rid of these unwanted pests. These flies do not stand a chance up against the Orkin  Canada technician.

Common Types of Flies

House Flies

The house fly is light grey in colour and around 4mm – 7.5mm long with 4 black strips on thorax. The abdomen is rather pale along the margin and sides and two transparent wings. These flies can be difficult to control once they gain access to your property because they can reproduce very quickly if there is a breeding source. You’ll want to get the fly swatter out immediately as soon as you see one fly into your open door.

Fruit Flies

These are the smallest of the three common property invading flies measuring in between 2.5mm – 4mm. They are light brown/ yellow in colour with bright red eyes. The common fruit fly with the bright red eyes is associated with over ripe or fermenting fruits and vegetables. While the dark-eyed fruit fly is associated with decaying organic matter. If there is rotting garbage or overripe fruit, these flies might be close by.

Cluster Flies

Cluster flies can be easily mistaken for house flies; however, they are larger, about 8 mm long and darker in colour with golden yellow hairs on body and the abdomen has light and dark irregular markings. They also fly a lot slower than house flies. In the spring, cluster flies can be a problem because this is when they emerge from overwintering sites to start breeding, gathering, and swarming around the outside windows of your house.

Why are Flies so Dangerous?

Aside from being annoying, flies are unwanted because they can pose a risk to our health. There are many ways that the common house fly can be a health risk. House flies repeatedly spit out their germ loaded saliva and suck it back up when feeding, which they do on top of the surfaces inside your property where you might be preparing food, you can imagine how unhygienic this is for humans.

Another way they pose a major risk to your health is when a fly lands on feces or rotting garbage, it picks up pathogens onto its body and brings it wherever else it lands. One of the many places that flies might land could be on your food, potentially exposing you to disease such as typhoid fever, cholera, bacillary dysentery, hepatitis, ophthalmia, or infantile diarrhea. It is important to be diligent with prevention to avoid an infestation in your home or business.

Tips To Keep Flies Outside 

House Flies & Fruit Flies

There are a few simple things you can do to prevent flies from coming inside your home or business. This would include some spring cleaning to ensure all drains are cleaned out and free from food and debris. You can also regularly clean out your garbage and compost bins and ensure there are tight fitting lids for each bin. It is also a good idea to inspect all of your windows and screens for holes or gaps in the caulking where the flies can squeeze themselves in. Lastly, check for any overripe fruit on counters that might be attracting fruit flies. If you follow these tips, it’s a good start to avoid house flies and fruit flies.
