I think I mentioned in another thread, I tried the motion sensor water thing. It didn't work. They eventually figured out a way to get onto my deck and do damage to my seedlings. You can only cover so much area with it, just when you think you have it tuned right, they still manage to find a way in. I also had problems with them being able to hide behind things on my deck (fooling the sensor), and if you ramp up the sensitivity, the slightest breeze can set the thing off, and your water bill is skyrocketing. It wouldn't be good near my figs; I would need at least two of them, and the nearby nanking cherry bushes would undoubtedly trigger them constantly.
