Pest identification
What's eating my echeveria setosa?
Mealybugs
Signs: White waxy masses hidden among the plant's own white hairs; plant becomes difficult to distinguish pest from pubescence — watch for honeydew and stunted growth
Control: Use a cotton swab dipped in 70% isopropyl alcohol to target bug clusters precisely; avoid saturating the hairy leaves; repeat every 10 days
Vine weevil grubs
Signs: Roots consumed underground; plant topples or wilts severely despite normal watering
Control: Inspect roots at repotting; apply Steinernema kraussei nematodes in autumn (UK) or use vine weevil killer compost drench
Fungus gnats
Signs: Larvae in overly moist soil attack fine roots; adults fly around the pot
Control: Water sparingly; use gritty, porous cactus compost; apply Bti drench or yellow sticky traps

Echeveria setosa pests — FAQ
What is eating my echeveria setosa?
Echeveria setosa, the Mexican firecracker plant, has dense white hairs covering its rosette that can trap mealybugs and make them very hard to spot and treat. These hairs also retain moisture, increasing the risk of fungal rot if treated carelessly with wet sprays. Mealybugs are by far the greatest pest threat; vine weevil grubs are a secondary root-level risk.
