Got Bugs!

[jakina22]

Hi all,

Recently a few non-orchid plants arrived from a family member and now I have a mess in my orchids (as well as the others). I am seeing white stuff (almost like a powder) on my potting medium, and in one case, it has made a 1 1/2 inch ring around the lower section of the outside of a pot as well as the rim around the top. I found small mealys (i think) and just recently a tiny worm was munching on my oncidium. I have tried alcohol without much luck.

I am going to get Bayer Rose or Garden Safe, but this is my first time with critters. Could someone tell me the best way to approach this? Should I water the plants first, spray leaves, medium and roots? I really don't know what to do and am looking for guidance- from start to finish. I have 15 orchids (all outside in beautiful Florida)- do I need to repot all of them?

I can provide photos later today if needed.

Thank you all so much for and advice or suggestions you can share.
