A stinking mealy bug!

[Pattywack]

Last weekend I found one very small mealy bug on my Seiryujishi!!! I've seen photos of huge ones, eeeew! I was very surprised and not at all happy. I got it on a toothpick and killed the little bastard with ISA and checked the plant thoroughly, found nothing more. I unpotted it but did not remove it from its moss mound. I've continued to check it twice daily since and I've found nothing. The bug was on the same fan that had recently flowered near the old spike. I have isolated the Seiryujishi from my other plants.

I have only ever had mealy bug once before ( One bug) on a Masdevallia, well over a year ago. Same situation, killed the bug, waited and checked daily, never had another bug and that Masdevallia is happy and healthy today.

I've no idea where this lone mealy originated from, I've not added any new plants recently, sadly. The Seiryujishi looks fine, new roots, new fans growing and it's flowers lasted about a month.

I found an old thread here where Matt had treated his Neofinetia for mealy bugs using 1:1 distilled water/hydrogen peroxide. I really don't want to blast this Seiryujishi with harsh treatments nor do I want an infestation!

It has been a week without any sign of bugs, any suggestions would be appreciated. Thanks!
