What's eating my sansevieria patens?

Sansevieria Patens forms a spreading rosette of cylindrical, groove-bearing leaves and is very drought-tolerant, which naturally reduces pest pressure. Mealybugs are most likely to colonise the grooved leaf channels. Spider mites appear in very dry indoor air. Root mealybugs may go unnoticed in overly wet soil conditions.

White powdery or cottony patches inside the distinctive leaf grooves and at the base of the rosette; honeydew and sooty mold follow. Use an alcohol cotton swab to remove visible bugs from inside the grooves. Follow with a neem oil or insecticidal soap spray and repeat weekly.

Light stippling along the round, channelled leaves; fine webbing at the rosette base indicates a heavier infestation. Wipe leaves with a damp cloth and apply insecticidal soap spray. Raise ambient humidity to discourage re-infestation.

White waxy colonies on roots and rhizome, detected only at repotting; above-ground decline without obvious cause. Remove from pot, wash all soil from roots, treat with a systemic drench, and repot in fresh, fast-draining cactus mix.
