For your edification.....here's a nice picture!
You will already know they are carriers of disease. (I don't fall into the houseproud category - cleaning and polishing daily - we are a 'lived in' household here), but I was surprised at just how many diseases these flies actually carry. Here's an extract from Wikipedia
The flies (musca domestica) are capable of carrying over 100 pathogens, such as those causing
- Bacillary Dysentery
- Parasitic worms
Life Cycle: Each female fly can lay approximately 500 eggs (in several batches of between 75-150. Within a day, larvae (maggots) hatch.
36 hours or so after emerging from the pupa, the female is receptive for mating.
These flies depend on warm temperatures; the warmer the weather, the faster the flies will develop.
House flies feed on liquid or semi liquid substances, household rubbish and faeces, beside solid material which has been softened by saliva or vomit. Because of their large intake of food, they deposit faeces constantly, one of the factors that makes the insect a dangerous carrier of pathogens. Although they are domestic flies, usually confined to human habitations, they can fly for several miles from the breeding place.
They are active only in daytime, and rest at night, e.g., at the corners of rooms, ceiling hangings, cellars, and barns, where they can survive the coldest winters by hibernation, and when spring arrives, adult flies are seen only a few days after the first thaw

......and to answer the question about noise......which was the reason why I researched in the first place
here's the answer I found
Returning to Greyhounds (ahh yes please) and food. I do actually cook for my two and so the food I give invites considerable interest to the fly species, so I cover each meal with a wet tea towel for the period it is 'out' until it is eaten or finished with, and this seems to deter them.
Hope you found this a fascinating post........not the best I know, but nevertheless I've learned a little more than I knew an hour ago......and, I have answered the question about noisy flies!
Have a good day all :)
