Mealybug Infestation: Identification and Treatment for Indoor Plants

Diagnosis: Mealybugs with Ant "Farmers"

The white pouches are mealybug egg sacs and protective wax. The black ants are "farming" them—collecting honeydew (insect excrement) and protecting the mealybugs from predators.

Immediate Alcohol Treatment

1. Dip cotton swabs in 70% isopropyl alcohol
2. Touch each visible mealybug—alcohol dissolves their wax coating
3. Check leaf undersides, stem crevices, pot rim, and soil surface
4. Repeat every 3 days for 2 weeks

Systemic Insecticide Option

For heavy infestations or large plants, apply a systemic insecticide (imidacloprid granules mixed into soil). The plant absorbs it, poisoning sap-feeding insects. Takes 5-10 days to translocate but provides weeks of protection.

Ant Control

Eliminate ants to prevent re-infestation: ant baits near the plant, sticky barriers on pot feet, or diatomaceous earth on soil surface.

Plant-Specific Advice

Identify your plant for tailored recommendations—some species are sensitive to alcohol or systemics. Send a photo if unsure.
