Sick orchids are such a bummer

[Djarum Black]

Ok, I was tempted *again* by a picture of a big old orchid on ebay. It was Onc. Sharry Baby and I already have 3 but my excuse was that this one was HUGE! I saw stars twinkling; you know how it goes...and you think you know the perfect place where it will fit in the house etc etc.

So it got here today...and the stars fell down right out of my sky

First, it had the BIGGEST scale females I have ever seen in my life! Second couple of the Pbulbs looked like things had been drilling into them. Then third looked like animals had kindly eaten and chewed most of the leaves. Roots were pretty yucky as well.

*sigh*
So I doused it in kerosene (j/k) No I drenched it in insecticide, removed the burrowed bulbs and whacked most of its roots off.
I just don't know if it's worth trying to save. I'm hoping I can but dang...

What are the odds do you think that it will infect the rest of my greenhouse down the line? I think I got all the visible pests off and I literally bathed it in insecticide. I've just never everrrr seen female scale covers that large before. It literally made my blood run cold. I've quarantined it for the time being but it really creeped me out.
