Our dogs are our best deterrents. I have a deer path about 30 feet from my garden. It's a busy highway with lots of deer coming and going from dusk to dawn. They graze on ornamental plants I have planted near the path but they have never entered my garden, even though my fence is only 4 feet high.
I've never tried any formal kind of deterrent so I have to believe my dogs are doing the trick--and they're inside the house at night, just barking several times each night. Every once in awhile their barking ratchets up a notch and I let them out and then something goes scurrying away.
I have overturned plastic milk crates over squash/pumpkin hills and those grew successfully protected from both chickens and deer (they were planted right next to the deer highway, outside the fence). I have also used stakes and chicken wire to make very narrow ovals around new fruit trees. The deer had been eating the tops off--the new green shoots--but after the chicken wire required them to put their heads down inside the oval they stopped doing that and the fruit trees grew well.
