Leafminer on Lemon Tree in Palm Springs: Tolerate or Trim?

Identification

White, curly trails on leaves = citrus leafminer larvae mining inside the leaf.

Trim off infested new growth (leafminer prefers flush growth).
Fertilize in cooler months to avoid stimulating flush during peak leafminer season.
Companion planting: Guava nearby may deter leafminer (observed in some regions).
Accept cosmetic damage: Mature leaves harden off; new growth replaces damaged ones.

Spraying is difficult due to rapid life cycle (eggs every 7 days).
