If you hate using dreaded stinky or "safe" fly killer spray , do what I do .
Use furniture wax spray polish.
If fly is on table say give a few sprays 20 inches above it . the mist will fall and make it's wings sticky and difficult to fly, then spray again closer .
If fly is on a wall , do o a quick spray from about 20 inches away and rapidly move closer with another blast to wax the wings and see it fall , Then kill it or move it outdoors , and have a nice smelling room .
If you are against aerosols , make a sticky solution and put it in a manual squeeze bottle .
