Pest identification
What's eating my hoodia parviflora?
Mealybugs
Signs: White fluffy masses lodged at spine bases, stem joints, and the soil line; sticky honeydew; growth stalls or tips shrivel.
Control: Spot-treat with isopropyl alcohol on cotton swabs. Spray neem oil or insecticidal soap every 7 days for three to four rounds, covering the full stem surface.
Root mealybugs
Signs: Gradual wilt despite adequate soil moisture; white mealy coating on roots revealed when plant is unpotted.
Control: Remove all growing medium, rinse roots, and soak in dilute imidacloprid or neem solution. Air-dry briefly, then repot in fresh sterile, gritty cactus substrate.
Fungus gnats
Signs: Adult gnats hovering near the pot; larvae feed on fine roots in wet soil, causing yellowing and slow decline.
Control: Allow soil to dry completely between waterings. Treat the soil with Bti granules or a dilute hydrogen peroxide drench. Use yellow sticky traps to monitor adult populations.

Hoodia parviflora pests — FAQ
What is eating my hoodia parviflora?
Hoodia parviflora is a spiny succulent stapeliad cultivated indoors by collectors. Mealybugs are its primary pest, exploiting the shelter of its spines and stem angles. Root mealybugs are a serious secondary risk given this plant's need for near-dry conditions. Fungus gnats strike if the substrate stays wet too long between waterings.
