Pest identification
What's eating my huernia brevirostris?
Mealybugs
Signs: White cottony deposits at stem bases or joint angles; root mealybugs cause gradual wilting — confirmed by white waxy powder visible on roots and pot interior when unpotted.
Control: Remove with 70% isopropyl alcohol swabs or a neem oil spray. For root mealybugs, unpot, scrub and dry roots, repot in sterile fresh compost. Use systemic insecticide drench if infestation is severe.
Scale insects
Signs: Small hard brown bumps on the four-angled stems, causing yellowing and weakened, distorted growth over time.
Control: Scrape off scales with a cotton swab dipped in isopropyl alcohol. Follow with a neem oil spray to catch hatching crawlers. Check again after two weeks.
Fungus gnats
Signs: Tiny black flies hovering near soil; larvae in wet compost feed on root tips, slowing growth or causing unexplained collapse.
Control: Allow compost to dry fully between waterings. Top-dress with coarse grit. Use yellow sticky traps and apply a Bacillus thuringiensis israelensis (Bti) soil drench.

Huernia brevirostris pests — FAQ
What is eating my huernia brevirostris?
Huernia brevirostris is a compact indoor stapeliad whose greatest pest threat is mealybugs — both stem and root-feeding types. Scale insects and spider mites are secondary risks. Fungus gnats can breed if compost is kept too wet. Fast-draining soil, careful watering, and monthly inspection prevent most problems.
