I have some weird problem in my house, whenever the weather gets warm
outside.. there will be 1 fly in my house per day.. I have no clue where
they get in. It is very annoying.

I even used those plastic window screen to block all the heater vents,
return vents and exhaust fans (there is no way fly can pass thro the
screen)
I checked everywhere on the 2nd/3rd floor. there is no holes. Where do
they come in? any idea??????

Many years ago I lived in an apartment that the flies would get into through
a small gap between the sliding glass doors.....maybe that
helps?????.....Ross
