Pest identification
What's eating my huernia keniensis?
Mealybugs
Signs: Cottony white clusters at stem bases and joints; stunted tips; honeydew and sooty mold on stem surfaces.
Control: Remove visible colonies with alcohol-dipped cotton swabs. Spray the whole plant with diluted neem oil or insecticidal soap every 7–10 days until clear.
Root mealybugs
Signs: Unexpected wilting and yellowing despite correct watering; white waxy deposits visible on roots when plant is removed from pot.
Control: Shake off all old medium, rinse roots, and treat with a systemic insecticide drench (imidacloprid) or neem soil soak. Repot in fresh gritty cactus mix.
Fungus gnats
Signs: Adult gnats hovering around soil; larvae in wet soil chew fine roots, causing slow decline and wilting in seedlings or small plants.
Control: Allow the top several centimetres of soil to dry completely between waterings. Apply Bacillus thuringiensis var. israelensis (Bti) or beneficial nematodes to the soil; use yellow sticky traps for adults.
