Answer 1

what you have in all likely hood are CLUSTER FLIES they have come in during the fall and have over wintered or hibernated and now with the warmer sun levels are emerging into your home.The cluster fly is a larger black ,sluggish  fly that will tend to go towards the windows or light bulbs.They can be in the walls and attic of the home the best time to treat is an exterior spray on the home in Sept-Oct to prevent entry,this should be done by a professional pest control company,at present you need to vacuum up the flies in the windows or call a company to come in and fog the attic and apply a residual spray around the window sills inside

Answer 2

Most flies start from maggots and those from eggs lid in a warm, moist, organicly rich environment.  The common housefly female fly can lay over 9,000 eggs. The eggs are white and are about 1.2 mm in length. Within a day, the larvae (maggots) hatch from the eggs; they live and feed in (usually dead and decaying) organic material, such as garbage or faeces. They are pale whitish, 3-9 mm long, thinner at the mouth end, and have no legs. At the end of their third instar, the maggots crawl to a dry cool place and transform into pupae, colored reddish or brown and about 8 mm long. The adult flies then emerge from the pupae. (This whole cycle is known as complete metamorphosis.) The adults live from half a month to a month in the wild, or longer in benign laboratory conditions. After having emerged from the pupae, the flies cease to grow; small flies are not young flies but the result of insufficient food during the larval stage.

Some 36 hours after having emerged from the pupa, the female is receptive for mating. The male mounts her from behind to inject sperm. Normally the female mates only once, storing the sperm to use it repeatedly for several sets of eggs. Males are territorial: they will defend a certain territory against other males and will attempt to mount any females that enter that territory.

Keeping flies at bay includes a clean house and a clean dry yard.  However if your neibors don't do the same, it is an uphill battle.  Additionally, if you live in an environment that provides a natural supply of fly habitat, the best you can do is fly exclusion (tight fitting screens, doors and windows).
