gants, gnats, gnats!

help! my house seems to be overrun with little flying things… that coupled with the local ladybug epidemic is driving me batty… we leave no standing water, but if anything sits in any room for more that 45 minutes its covered with little fly thingies, its worst in the kitchen even though we’ve taken to not leaving any water sit, and just dumping the trash in the can outside as opposed to inside the house. any help?
