What kills mealybugs instantly?
Soak a cotton ball with regular rubbing alcohol and wipe it on the mealybugs, which kills mealybugs instantly and removes them. 4 Use a solution consisting of no more than 70% isopropyl alcohol, and test it on one leaf before you apply it to the whole plant to make sure the alcohol doesn’t burn it.
Can mealybugs infest your house?
Mealybugs will heavily infest almost any plants in greenhouses, homes or businesses.
