I suppose you could go for a more practical Alabama Legislator vampire-killing route as follows. We don't use these when they adjourn for recess, I swear!
You use a revolver-type gun that accepts cartridges pressurized air to sling a single foot-long, 9mm wide wooden stake covered in WD-40 into the heart of the poor fucker on the other end. As it exits the chamber, a pilot light ignites the WD-40 and sends a burning wooden stake straight into the heart of the vampiric fiend.
He ain't getting back up after that, I can assure you.
