Identifying Leaf Damage on Canna 'Tropicanna': Slugs, Snails, or Pill Bugs in Screened Enclosures

Perfect Holes in Canna Leaves

Likely culprits: slugs, snails, or pill bugs (rolly‑pollies). Even screened areas can harbor them.

Control

  • Set shallow beer traps at soil level.
  • Or use commercial slug/snail bait.

Check at night with a flashlight to confirm.
