Hello everyone!

i just found on one of my Phal some mealy bugs. That looks like cotton-wool
like substance on the flower spike and under some leaves.

According to theGuide to growing Orcjids by Wilma and Brian Rittershausen, I
should use denatures alcohol to get rid of the bugs.

Can I use rubbing alcohol, isopropylic alcohol 70% ?

Thanks

Claude
