New to this Forum - chanced upon same as I browsed the Internet this stifling hot day - and saw this topic and wondered if you might be interested in how I beat the odds and keep the deer at bay?.
I have a largish garden - 2 acres (Central Southern Ontario) with a fair number of flower beds and a large vegetable patch (lot smaller than it once was).
With thousands of acres of virgin bush and pasture land all around (right in the heart of rural Ontario) three years ago I found my gardens were being devastated by a number of roving white tailed deer who had decided we could supply them with delectables they could not find elsewhere. They feasted long and often and I was soon beside myself in anger and frustration. Especially so when they became so bold as to come into the garden whilst I was working in it!
After losing every Hosta (more than fifty) and many other plants - what were not eaten were trampled - we sought help. Had a friend who suggested a remedy which he had used and knew worked. His remedy consisted of installing an electric drill (old beaten up wreck, but the motor still turned) on a fence post. Connected by cable through a Motion Sensor to the house power supply. In the drill chuck, he put a long bolt which had been driven into a squared block of wood. Once in place and the chuck tightened so it could not slip, over the wood he placed an empty I kilo coffee tin.
After setting the motion sensor to work on a five second cycle, this covered the main entrance the deer used, when their motion activated the motion sensor on, the drill engaged and the ensuing racket was abominable! They would turn and flee! As would anything that came into his garden.
Now I have elderly neighbours on one side of me and I thought perhaps they would not take kindly to this racket taking place during the dark hours, when they were fast asleep, so had the idea that perhaps a cheap radio replacing the drill set-up, tuned to a modern rock station might be just as effective and less of an incursion to their sleep?
End result? I now have four such devices set up and have not seen a single deer or a footprint in my garden since the second such set up was installed. No damage to a single plant in three years! The other two set-ups were installed more as a safeguard to cover any smart white tailed deer who might think to approach from the other side!
For what it's worth? I found it a cheap and maintenance free answer to my problem, and I can sleep easier at nights, knowing my garden is guarded well.
