Unfortunately, mealy bugs can also be pest on outdoor woody plants, like your hydrangea, but the control strategies are the same. You can reduce their numbers by swabbing away the clusters you see with a Q-tip dipped in rubbing alcohol. Then spray the plants with insecticidal soap or neem oil. You'll need to make repeat applications because the only vulnerable stage is the mobile crawler, that moves about on the plant for a short time after hatching out before settling down to feed and secrete a waxy coating to protect itself. So you need to spray every week to ten days to pick off the crawlers.
