When we go out to get our mail right now, there are hundreds of cluster flies all over the front steps and yard. They create a low droning hum and swarm all around as you walk. And it is very creepy.
Supposedly, the Amityville house was plagued by swarms of flies despite the winter weather (December/January). What that tells me is that they had Cluster Flies. These flies get their name from their habit of clustering in attics or near windows. (Sound familiar, Amity fans?)
The Amityville house had been previously unoccupied for over a year. When the Lutz family moved in and turned the heat on, conditions were perfect to trigger a massive cluster fly emergence.
Cluster flies find shelter from the winter by crawling under your siding or in foundation cracks. When you turn on the heat that warms the flies up, and they find a way inside via electrical outlets, baseboards, or door.
No satanic mystery for the sudden fly emergence at all. In fact, the flies might be the only real part of the Amityville story.
Oh, and if you want to asplode your head, read this Yahoo Answers page discussing “are flies linked to paranormal activity?” URG.
So, back to the Bug House and our massive clusterfuck fly problem.
OMGWTFGHOSTS? Um, no. Worms, actually.
Although they are blowfly relatives, cluster flies are not carrion flies, but a type of fly parasitic on earthworms. They are harmless, and do not carry any human diseases. They are, however, annoying as hell, and poop all over everything as well.
While I normally just vacuum them up, this year I might have to do something. I don’t want to scare potential home buyers away with a giant roaring wall of (harmless) flies. I really don’t want to spray for something so cosmetic, though. Sigh.
