S.S.
Totally empathize with you and unfortunately my husband has relatives like this (ok no deer but they used to show up unannounced all the time) OR the phone would ring right when it was dinner time and he would talk to them for hours and hours. There went dinner...In about the last couple of years (sorry it did take a long time) he himself began to see what leaches and annoyances they were and they do not appear too much anymore and he doesn't really seem to want to spend time with them either now that he has a more stressful job and little time on weekends to do his own thing. I wish I had advice, I don't because every now and then, just when I get comfortable...ring, ring. There was one thing I used to do and that was (is this possible for you?) I just started to leave and disappear when they showed up. For some reason that also bothered him. Well, like I said I have no advice, only empathy. My friends were always courteous about not calling at the wrong time, or took the hint 'gee we just sat down to dinner' but some don't. What to do what to do, who exactly knows. Good luck, good luck!
