Here in N. Georgia the Apple Farmers have propane cannons.  20# propane
bottle with an attachment.  The propane leaks into a pipe and about every 15
minutes a spark sets it off.

At reagan national airport here they have air cannon...just long tubes
with I would assume a valve on a timed solenoid, I'd guess. Keeps the
birds off the runway. Seems like it whouldnt be too hard to rig that up
with a motion sensor you can buy at home depot. Dunno if the deer would
get used to it or not. You neighbors (if you're unlucky enough to have
any) might not.
