They only live for 21 days, so if you can't get rid by then, he'll die and disappear. They do make flytraps, too.
febreeze! my mom used to go around the house spraying them with soapy water and that worked well. they would fall out of the air and she would just pick them up with a napkin. the advantage of febreeze is that it wont make your kitchen floors as slippery or build up like soapy residue (plus it makes the house smell nice). it's actually sorta fun and less frustrating and nasty than chasing them with a rolled up newspaper.
You can also swing a pillow at them super fast. Don't hit them with it (that'd be gross), the fast moving air will knock them out of the air like a mini shock wave. This one is just as good as the newspaper for breaking things around the house though!
Leave the house to the flies .....
cheap skate,hang several qt bags of water around the house,flys hate to look at themselves
Trays of crushed egg shell in the window, & no flys
If your talking about getting rid of houseflies? O.K. Get rid of any and all food scraps in and around your doorways, don't have a dog or any other pet around the doorway entrances, make sure any kids close the doors when going out or in.
Keep all food sources covered in the house, don't leave scraps laying around. Keep your garbage covered and take it out at least every night. Keep your place clean is what I'm saying.
Then spray the place with Raid Flying Insect Killer, go for a walk for about one hour, go visit a friend, go to the store. Get out for an hour.
Go back and sweep the floor of flies. That should do it.
