Holes in Black-Eyed Susan Blooms: Identifying and Controlling Pests

Tiny holes in black-eyed Susan petals indicate flea beetles, aphids, or slugs.

Pest Identification and Control

Flea beetles/aphids: Spray pyrethrum or rotenone (organic) on foliage, especially undersides.
Slugs: Check at dusk under mulch. Use Sluggo or Escar-Go (iron phosphate baits).

Gardens Alive and Planet Natural carry these organic controls.
