What's eating my echinocereus coccineus?
Cochineal scale (Dactylopius spp.)
Signs: Woolly white deposits on stems; feeding causes pale, sunken spots and can lead to rot if the cuticle is broken in wet conditions
Control: Dab with isopropyl alcohol on a cotton swab; spray with diluted neem oil; remove heavily infested pads and dispose
Spider mites
Signs: Fine tan or silvery stippling across the stem surface; webbing may appear at the spine areoles in severe infestations
Control: Mist with water to raise humidity and dislodge mites; treat with insecticidal soap spray; avoid hot, dusty positions
Rodents
Signs: Chewed or hollowed stem bases; rodents cache seeds and may undermine roots when burrowing nearby
Control: Use wire mesh guards around individual plants; set humane traps where legal; coarse grit mulch discourages burrowing
