Pepper Leaf Holes: Nocturnal Pest Identification and Control

Big Holes in Pepper Leaves, No Bugs Visible: Night Feeders

Large holes in pepper leaves with no daytime insects = nocturnal feeders: cutworms, earwigs, slugs, or beetles.

Nocturnal Pest Identification

Pest	Damage	Signs	Trap/Confirm
Cutworms	Large irregular holes, stem cutting at soil line	Curled caterpillars in soil day	Flashlight at 10 PM, dig 2" at base
Earwigs	Ragged holes, hide in flower buds	Under mulch, pots	Rolled newspaper traps
Slugs/Snails	Smooth holes, slime trails	Silvery trails at dawn	Beer traps, check under pots
Flea Beetles	Tiny shot holes (not "big")	Jump when disturbed	Yellow sticky traps

Organic Control Protocol

Diatomaceous earth: Band 2 inches wide around each plant, reapply after rain
Sevin alternative: Spinosad (Captain Jack's) - organic, effective on caterpillars/beetles
Beneficial nematodes: Steinernema carpocapsae for cutworms in soil
Habitat reduction: Remove mulch touching stems, clear debris

Night Inspection Routine

10 PM with headlamp, 3 nights in a row. Catch them in act—definitive ID.

Most "invisible" pepper damage is cutworms or earwigs. DE + spinosad + night check solves 90%.
