Hi, thanks for all suggestions guys. I am having trouble with my pc these days.
will keep you updated with my orchids. The den has keiki, a healthy keiki. i did checked the root and they are fine (I saw a lizzard coming out though

)
The keiki is on its own now, safe and sound.
But the mother? oh man, I think she will die.
i will keep trying to safe her life.
I will update you with the pesticide I use here soon.
Ciao for now.
