At a distance like 24" most of the fog should stay airborne and drift.
Since it's a fogger nozzle and not a spray one, it's not going to hit
the subfloor much. Try a regular spray bottle of glass cleaner as an
example and see how much will hit a ceiling 24" away. If you can
identify the position of the pickup tube in the can (usually marked with
a dot on a paint can) and keep that point down, you can get well over 45
degrees and still get full dispensing.
