| Hi Christina.
I use a small craft paint brush dipped in metho to wipe off the mealybug.
The mealy bugs also get into the potting mix and live on and around the root system.
I always repot all new orchids going into my orchid house.
As the flower spike is soft new growth the mealy bugs tend to all head up there for a feed.
You may get most of them but there next generation eggs will be in the root system.
cheerio
