How do I prevent lizards from eating orchid blooms?

[CR7cristiano]

I have noticed some of my orchid blooms and even sometimes the roots of my orchids eaten partially or even completely. These orchids are outside and up until now I had no idea what it was.
Now I managed to catch a lizard in the act of eating a bit of an unopened bloom on my new Vanda spike who's buds have started to separate from the spike and get larger and take on colour.
It actually bit a hole through the unopened bloom, thankfully i caught it in time. Had i realized initially i would have caught it and done away with it.

I need to know how i can either rid the area outside of lizards where the orchids are, or how do I prevent them from eating my orchid blooms; which in turn deforms the otherwise beautiful blooms.

Someone please help ASAP!
