Houseflies, on the other hand, reach their peak of indoor activity during the warmest part of summer. Cluster flies are not known to carry disease. Cluster flies are a longer-lived species, with adults living as long as two years under ideal circumstances.
Houseflies, on the other hand, typically go through their entire lifecycle in about 15 to 30 days depending upon temperature and living conditions.

Warning While pyrethrins are some of the less toxic pesticides, they will kill all insects, including beneficial insects such as pollinator honey bees. Do cluster flies carry disease? How long do cluster flies live?
Do cluster flies bite? Featured Video. Article Sources. Flies avoid being swatted in just the same way Keanu Reeves dodges flying bullets in the movie The Matrix — by watching time pass slowly. To the insect, that rolled-up newspaper moving at lightning speed might as well be inching through thick treacle.
Like Reeves standing back and side-stepping slo-mo bullets, the fly has ample time to escape. And it is not alone in its ability to perceive time differently from us. Research suggests that across a wide range of species, time perception is directly related to size. Generally the smaller an animal is, and the faster its metabolic rate, the slower time passes. The evidence comes from research into the ability of animals to detect separate flashes of fast-flickering light.
Comparing studies of the phenomenon in different animals revealed the link with size. Animals smaller than us see the world in slo-mo. It seems to be almost a fact of life.
It turns out this rate is different for every animal. The general rule is: the smaller the species, the quicker the vision. Humans see about 60 flashes per second while flies see about — a full four times faster than humans.
A quick note about trying to get your dog to watch TV: The refresh-rate on traditional TVs is about 60Hz, which is on par with the flicker-fusion frequency of humans. However, dogs see at about 80Hz, which means that unless you have a high-quality TV, your favorite movie appears as rapid-fire still images to your dog.
The fastest-seeing flies are blindingly quick, even relative to their own kind. Image: flysy. Why is the killer fly so much faster? For this insect, time moves in extra-slow motion — about six times slower than it does for humans.
