Control: Increase irrigation and ambient humidity; apply neem oil or a labeled miticide; avoid drought stress

Slugs and snails

Signs: Irregular ragged holes and slime trails on newly emerging spear leaves and young fronds

Control: Apply ferric phosphate slug pellets around the base; use copper tape on containers; remove mulch piles where slugs shelter

Red palm weevil (Rhynchophorus ferrugineus) — risk in Mediterranean/coastal climates

Signs: Larvae bore into the crown causing sudden spear collapse and death; adult weevils visible near crown
