Pepper, Eggplant : Flea beetles
(revision date: 3/10/2017)


Use Integrated Pest Management (IPM) for successful plant problem management.

Biology
Flea beetles are small, brown to metallic black beetles with a habit of jumping like fleas when disturbed. They feed on many plants including beets, kale, collards, radish, and many weeds, particularly those in the mustard family. Small round holes are eaten in the leaves, usually early in the season. The larvae typically feed on underground portions of the host plants. Damage can be very severe on seedling plants.
Management Options

Non-Chemical Management
  • Keep garden and adjacent areas clear of weeds which may attract flea beetles.
Select non-chemical management options as your first choice!
