and does it drive humans crazy in the process, or other animals?

I think it's the type of sound that humans can't hear as well as the deer can (something like that) and when you are near the detector (working in the garden), you can shut it off. I am three acres apart from any neighbors, and hopefully no one could hear it if it went off at night - (I don't want to hear it either).... Hopefully someone has used it (successfully) and can let us know if it really works.

Here's hoping that they don't come to treat it like the dinner bell.

LOL - gosh, dottie - never thought of THAT! Ha Ha.... how about a little soap with the sound? (This is getting ridiculous... one of these days, I am going to put a large bowl of "deer food" out... so they don't eat the plants... Any ideas?

Deer ain't stupid. They will eventually outsmart any barriers you install. A hungry deer will browse in a highway median totally ignoring the traffic. It would probably take a season for them to learn the sonic warning meant nothing - just like it takes only a month or so for them to learn that soap is harmless or that a fat dog can only run so fast. Feeding them only makes the problem worse. Plenty of people have been attacked by stags in 'rut' because they have been conditioned to live in and around people. (rut, is the male equivalent to being in 'heat'. They go crazy with lust and attack anything deer sized that they perceive to be a opponent).

The only thing that really works is a deer fence, either the wooden stockade type or the virtually invisible black netting type. And even they need to be maintained and properly installed.

If you do a search back through the archives of this forum you will find plenty of posts about deer eating plants on the popular 'deer proof' lists. All deer nibble on everything, when they find something they like (which can change from night to night) they all take a healthy serving. Young deer will chew on anything, even the poisonous plants.

If I lived in a deer prone neighborhood, and was not allowed to install a proper deer excluding fence to protect my garden, I would move.

A loud device that gets rid of deer? It's called a shot gun....

I think John is right...the deer are relentless, and not much slows them down. I am considering an electric fence around the property line. What a pain, but I have daylilies I haven't even seen bloom yet because of the deer. I am also considering a cross bow...

Thanks everyone - you've saved me some money bec i won't be buying any sonic devices - Oh well, can't fence my gardens in (three acres of fencing), so I have to resort to something else... what? Beats me! Ha Ha

John is right about the deer eating anything, anywhere, but I still say they're stupid. I guess they now think the anti-deer pepper spray is just Brenda serving them their entres Cajun-style. I ordered the new "Deer Fortress" product. Anyone tried it?
