Mealybugs look like tiny bits of white cotton or mold. They hide in the nooks and crannies where leaves meet the stem.

The Weapon: Isopropyl Alcohol (70%)

Mealybugs have a waxy coating that repels water sprays. Alcohol dissolves this wax and kills them on contact.

Treatment Steps

1. The Q-Tip Hunt

Dip a cotton swab (Q-tip) in rubbing alcohol. Touch it directly to the white fluff. It will turn orange/brown and die instantly. This is satisfying but tedious.

2. The Spray

For larger infestations, mix a spray:

  • 1 cup water
  • 1/2 cup Isopropyl alcohol
  • 1 tsp Dish soap Spray the entire plant, getting into every crevice.

3. Repeat

Mealybug babies (crawlers) are tiny. Repeat treatment every 5-7 days for a month.
