Holes in Phalaenopsis Leaves: Snails, Not Flies

Identifying the Real Culprit Behind Chewed Orchid Leaves

White flies (likely fungus gnats) don't chew leaves—they lack biting mouthparts. The real pest is probably a bush snail hiding in the potting mix, emerging at night to rasp holes in leaves.

Effective Control

1. Apply snail/slug bait (metaldehyde or iron phosphate) per label directions.
2. Inspect leaf undersides and pot rims nightly with a flashlight.
3. Repot in fresh media to eliminate eggs/hiding spots.
4. Use sticky traps for flying insects (fungus gnats).

Prevention

• Keep growing area clean of debris
• Water in morning so foliage dries by night
• Quarantine new plants
