Not sure what kind of deer you have in CA, but I have had luck in Michigan with white tail deer with Liquid Fence. Unfortunately in Michigan, a six foot fence will do nothing to deter white tails, since they can hop a six foot fence like a five year old child can hop over a crack in the sidewalk!

I have recently relocated to CO where Mule Deer and Elk are rampant. As soon as the planting season arrives, I will find out if Liquid Fence will work with them or not!

Hi!
Have you tried those electronic repellents? They are usefull and easy to use.
Hope that helps!

Did the electric repellents work for you? I already tried the wireless deer fence, but it didn't work. I am going to get the Liquid fence, but it sounds smelly. If these repellents work, I would much rather use them because they are (according to the website) odorless.

Can you lay woven wire or chicken wire across your drive? They will not walk on it and it shouldn't bother to drive on it. You will need 12 ft. or so wide or they will jump it.

8' is what's suggested here in MD too. There is a grate that you can put in the ground that 'supposedly' they won't walk over.

The wireless zappers didn't work here either.
