I remember years ago I was at a bar and a girl who was a stranger to me at the time freaked out and jumped up and screamed because something was on the wall next to her.
Because I owned the bar I ran over to see what I could do to help. What was it? A spider?.. a cockroach?...a centipede? a rat?.....a Velociraptor? What could possibly make this woman near freak out?
It was a gecko or as they call them in Thai, "jink-joke."

I suppose I could understand her reaction if that was the very first time she had seen one but I calmly tried to explain to her that this "phobia" of hers is something she is going to need to get past pretty quickly because these little guys are not only totally harmless, but they are literally everywhere.
I was once visiting a summer palace for the Royal Family and they were all over the wall in that place. If they are in the King's Palace, they are unstoppable... end of story.
They also eat other things that actually will hurt you such as mosquitoes and they also have a feast when the flying ants come out after a rain storm and swarm any light source.
I think most people realize this guys are harmless and unavoidable but go ahead and prepare yourself for them if you visit Thailand or really any part of south-east Asia because you will see them, I guarantee it.
That last image has no source because I TOOK IT! look how artsy I am.
I quite like these little fellas and except for the poo they leave in the corners of your house you really don't even notice they are there. Get used to them, don't kill them and don't try to catch them (they are very fast.) Embrace the fact that no matter the precautions you take, you will be sharing your room or your house with these guys.... and that is just the way it is.
