Andrew,
first, the
urine thing only works if you are a
deer eater, vegetarians get no respect. But deer blood works better.
second, forget about can't and work on won't - deer will only jump a
fence if they can see what is on the other side.
third, deer netting works great by itself, I think because it is almost invisible. Would you walk thru a spiderweb as strong as netting? I think not.
fourth, fengshui for evil spirits seems to work, you might try mirror chimes.
fifth, forget about 'sacrifice' you are just attracting them. Plant things they hate outside your garden.
