Go to "Mike's Falconry" and order up a couple of his sparrow traps. take 2 saw horses and lay a sheet of plywood on them. bait the surface with bird seed until the little darlings are all coming to it. Put your traps on the surface, leave a little seed outside the trap doors. Soon they will find their way into the trap. Now comes the hard part...everybody must die. I like to leave one to entice others into the trap. So leave two alive in one trap, take the other trap with all the sparrows in it, place it in a large box with a hole in it the same height as your tail pipe on your truck. You know how this ends. hiring a guy like me to haze the sparrows out will cost you a fortune and it will only work as long as you keep at it.
