Help with flies!?

Question

Can flies get into my house through the air conditioner when it's turned on? I don't leave any doors or windows open, yet I have a butt load of flies in here... I reckon the only other way is through the vents in the AC... Is this possible?

Answer 1

Hate to say it but flies come from maggots.  Check your house.  They are in there somewhere.

No, they don't come in from a/c.
