The best product to use indoors is CB 80 Aerosol. This is a handheld aerosol sort of like hair spray that you spray into the air. Usually a 2-3 second blast in the average room will kill all the flies within minutes. Just spray it and the go do something outside for a few minutes and let it dissipate. CB 80 contains natural pyrethrins, and is not extremely toxic to humans or pets, although you do not want to breath it.
Outdoors, use the Fly's Be Gone Fly Trap. Place it away from the home and not close to it. This trap will attract flies away from the house like a magnet. 2 or 3 traps placed outdoors will work wonders, and last for several months.
Spraying outdoors with a product such as Bifen will also help. Just spray the lawn, under shrubs, trees, around doors, windows, etc. Anywhere the flies could be living, breeding etc.
A really useful bait indoors is Maxforce Fly Spot bait. Dilute this bait in water, such as in a "windex bottle" and spray it on trash cans, on window sills, and anywhere the flies land or rest. It works great.
Indoor electronic fly traps for home use, usually do not provide enough control, and also do not attact the fly problem at its source. Finding the source, or keeping the flies at bay outdoors, is always the best treatment plan.
Hope this helps.
