This blog will unravel the mysteries surrounding this everyday occurrence. We’ll introduce the various types of flies involved, discuss potential health considerations, and offer effective solutions for this intriguing issue. Join us as we journey into the world of flies and windowsills!
Why Do I Keep Finding Dead Flies on My Windowsill?
Flies are naturally drawn to light, and they see your windows as possible escape routes from inside.
The reason behind this is simple: windows allow certain types of light called UVA to come through, but they block out another type of light called UVB. This difference in light confuses insects like flies, messing up their visual cues.
As a result, flies keep trying to fly towards the light coming through the window, hoping to get out. Unfortunately, they often end up stuck, either in the window screen or behind it, with no way to get free.
In their determined attempts to find an exit, flies use up all the energy stored in their bodies, which comes from the fat they have. Eventually, they become so tired that they can’t go on, and that’s when they meet their end on your windowsill.
What Type of Flies Are Perishing on My Windowsill?
The most common fly you’ll find deceased on your windowsill is the everyday Adult Cluster Fly. However, you might encounter a variety of intriguing insects in your window tracks, and not all of them are harmless. Be cautious when dealing with them.
The Adult Cluster Fly is approximately 1/3 of an inch in length. This typical fly has transparent wings with a network of veins.
Its overall appearance may seem gray due to its black body adorned with a silver checkered pattern. You’ll also notice small golden hairs around its thorax.
Usually, where there’s one Cluster Fly, there are many, which is why they have that name. However, it’s not uncommon to find common house flies on your windowsill as well.
House flies are smaller than cluster flies and typically enter your home in search of food and water.
Cluster flies, on the other hand, are seeking warmth. That’s why you often see them appearing in the spring months after hibernating in your home throughout the fall and winter.
Can The Deceased Flies on My Windowsill Pose Health Risks?
Cluster flies, although bothersome, seldom pose a health risk to humans. They are generally harmless and unlikely to cause any harm to your home, except for the occasional droppings left on walls and their lifeless bodies on your windowsills.
However, it’s essential to note that Cluster flies are not the only type of insects you may find deceased on your windowsill. Some insects feed on animal feces and carcasses, and as a result, they can carry diseases that have the potential to make you ill.
What Is the Significance of Finding Dead Flies on My Windowsill?
Discovering dead flies on your windowsill may indicate the presence of a cluster fly infestation within your home or building.
It’s important to note that finding dead flies on your windowsill doesn’t necessarily imply poor hygiene, especially if they are cluster flies.
If you observe multiple deceased flies of the same type on your windowsill or in the window tracks, it’s highly probable that there are more of them elsewhere in your vicinity.
How Can I Eliminate the Dead Flies Accumulated on My Windowsill?
Even pest control experts acknowledge that preventing a Cluster Fly infestation can be quite challenging. Cluster Flies often select a residence on a block seemingly at random, mainly because they’ve found a warm spot to hibernate.
Once they’ve chosen your house, you might continue to see them year after year.
Nevertheless, you can take certain steps to keep these flies from entering your home in the first place.
Inspect your home for potential entry points, such as cracks in walls or floorboards, holes in window screens, and damaged weather stripping. Seal these openings; window caulking is effective for tight spaces.
If you’ve noticed other types of insects on your windowsill, some experts suggest using salt near the windows to deter pests like slugs, snails, and ants.
