What is the difference between cluster flies and house flies? They are easily confused, however they are quite different, so let our pest experts give you an insight into differentiating between the two.
Neither fly does particular harm to a household, but cluster flies can cause panic due to their sudden appearance in very large numbers. These pests are capable of crawling through small openings in walls and like to hibernate in secluded parts of houses such as attics and wall voids.
However, with the correct knowledge and products you can make dealing with how to get rid of cluster flies simple and stress free.
Identifying a cluster fly
Here we are going to look in more detail into how you can identify a cluster fly so you can treat the pest much more quickly. In general cluster flies are slightly larger and darker than your common housefly and tend to move more sluggishly.
Adults grow to be 3/8thin length. The appearance of a cluster fly sets it apart from a housefly because it is not metallic in appearance, but instead has yellowish-gold hairs on its thorax and legs. This is a top tip when distinguishing between the two sets of flies.
You can also identify a cluster fly through where they hide in the winter period. They tend to appear in heaviest concentrations in late autumn and early winter, seeking out warm locations to live during the winter period.
Common places for cluster flies to hide are in homes, sheds, between cracks in rocks or underneath a dead or dying tree. In the Spring, they emerge from these hiding places and can be found outside clustering around flowers or fruit, hence the name.
- Appearance– Less metallic and more yellowish around the thorax and legs.
- Movement– Sluggish movement compared to a housefly.
- Location– Usually found in protected areas e.g. house, wall cracks, between cracks in rocks.
- Wings– When resting a cluster fly overlaps it wings whereas a housefly’s remain separate.
Identifying a house fly
Now you know how to identify a cluster fly we are going to provide you with some top ways you can identify a housefly. Houseflies are more common than cluster flies and grow between 5-7mm in length. They feature reddish eyes and their thorax bears narrow black stripes and has a distinct sharp upward bend in its fourth longitudinal wing vein.
You will also notice that the housefly is inactive at night and can be found resting in ceilings, beams, overhead wires and shrubs. Our pest experts recommend keeping a close eye on these areas to prevent an infestation sooner.
Less commonly known, houseflies are limited to a 100% liquid diet and require a source of water to survive indoors whereas cluster flies don’t require such a diet. As mentioned above, when trying to decide what type of fly you have, look closely at the wings as these flies will keep their wings separate.
- Appearance– Distinctly grey and feature black stripes along their bodies.
- Movement- More frantic and faster than cluster flies.
- Location– Usually found at night in ceilings, beams and overhead wires.
- Wings– When resting a house fly keeps its wings separate.
Best way to prevent
There are many precautions you can implement to prevent the infestation of cluster flies and house flies and our experts highly recommend you act sooner rather than later. Some of the best ways to prevent cluster flies and house fly infestations are by:
- Filling in as many cracks and crevices around your home more importantly surrounding doors, windows, along roofs and around vents. We also recommend replacing or repairing damaged screens or doors.
- Remove any excess waste or rubbish from your home as flies are attracted to such areas.
- Ensure all doors and windows are tightly fitted as these pests can easily squeeze through gaps or cracks.
