Pest identification
What's eating my sansevieria ehrenbergii?
Mealybugs
Signs: Cottony white fluff deep in the leaf channels and at stem bases; honeydew residue and stunted new growth.
Control: Use a cotton swab with 70% isopropyl alcohol to reach into crevices. Follow with a neem oil soil drench and spray every 7–10 days.
Fungus gnats
Signs: Tiny flies hovering at soil level; larvae chew roots in waterlogged gritty mix, causing wilting.
Control: Ensure the mix dries completely before re-watering. Apply Bti-based drench and use yellow sticky traps to catch adults.
Scale insects
Signs: Small hard shells adhered to stems; scale feeding causes localised yellowing and slow growth.
Control: Scrape off with a soft toothbrush and treat with diluted horticultural oil spray repeated every 10–14 days.

What is eating my sansevieria ehrenbergii?
Dracaena ehrenbergii (Blue Sansevieria) is a robust succulent-type houseplant. Mealybugs are the primary indoor pest, sheltering in the deep channelled leaf bases. Fungus gnats appear when the well-draining mix is kept too wet. Scale occasionally infests the stiff stems. Dry conditions and good airflow are its best defence.
