Mealybugs

These small, soft-bodied insects secrete a white, waxy substance that looks like cotton. They tend to hide in the leaf axils and at the base of the Aechmea's central reservoir (tank) to suck sap.

Very Common

How to confirm: Inspect the tight crevices where the leaves meet the stem for tiny moving insects or white clusters.

1 Isolate the plant immediately to prevent the mealybugs from spreading to other houseplants.
2 Use a cotton swab dipped in isopropyl alcohol to manually remove the visible white cottony masses from the leaf axils and central reservoir.
3 Apply an organic insecticide spray to the entire plant, ensuring you reach the base of the tank, to eliminate remaining insects and larvae.

Scale Insects

While often more bumpy than cottony, some species of scale can produce fine, white fungal growth or wax that mimics a cottony texture on the underside of Aechmea leaves.

Common

How to confirm: Check if the white spots are firmly attached to the leaf surface and cannot be easily wiped away like dust.

2 Carefully wipe the underside of the leaves with a cotton swab dipped in isopropyl alcohol to physically remove visible scale insects and white residue.
3 Monitor the plant's environment for high humidity, which can encourage secondary fungal growth, and ensure good airflow around the foliage.
warning

Botrytis (Gray Mold)

High humidity combined with stagnant water in the central tank can trigger fungal growth. This often appears as fuzzy, white-to-gray patches on decaying organic matter or leaf edges.

Common

How to confirm: Check if the white spots are accompanied by soft, brown, decaying tissue near the base of the plant.
