deer are smart, they learn your NOT a threat and thus, don;'t run from you, but they MIGHT from others
I have hunted a lot of farms over the yrs, where the deer ignored farmers, but if a different truck pulled up, BOOM off they were like a rocket ship!
if you wanted deer gone, a trip to your local gun shop or archery shop, will most likely get you a list of folks wanting access to help you out.
I have known a few farmers that used to ask store owners to get a list of folks names and numbers and then would do like interviews, to find one's he trusted to come and hunt and kill some deer for them
Food for thought for you if you really want some help
another road, is talk to local wardens, most states have CO OP deals where they can get farmers hunters too!, or you can maybe get some farm tags and shoot as needed and donate the meat to a meat bank?
