Slugs vs Cutworms

Separate slug chewing from cutworm clipping before re-sowing seedlings, changing mulch, drying beds, adding collars, or covering rows.

What each seedling signal means

Slugs
Slugs are soft-bodied night feeders that rasp irregular holes in leaves and seedlings, leave shiny slime trails, and stay active where soil, mulch, boards, weeds, or plant debris keep conditions moist.
Cutworms
Cutworms are moth larvae that usually feed at night, hide in soil or residue during the day, and can cut young seedlings at or just below the soil line so plants disappear suddenly.
Ragged holes and slime trails
Ragged leaf holes, shredded edges, slime trails, and damage that increases after wet nights point toward slugs or snails before assuming a stem-clipping caterpillar.
Cut stems and missing seedlings
Cleanly severed stems, seedlings clipped near the ground, and nearby curled C-shaped larvae point toward cutworms, especially where weeds or residue sheltered larvae before planting.
Night scouting and hiding places
Scout after dark and check under boards, mulch, leaves, soil clods, weeds, and plant residue; the hiding place and feeding pattern decide whether to dry habitat, handpick, use collars, or protect rows.

Seedling protection workflow

Check the injury pattern first
Do not re-sow every missing seedling before checking the damage pattern; look for slime trails, ragged leaf holes, clean soil-line cuts, C-shaped larvae, wet shelter, weeds, collars, and row-cover timing before changing water, mulch, protection, or pest controls.
Scout at night or early morning
Use a flashlight after dark or lift nearby shelters in the morning so the active pest, not only the damaged seedling, drives the response.
Change habitat before chemicals
For slugs, reduce wet shelter, weeds, boards, and dense debris around seedlings, then handpick or trap where pressure is visible. For cutworms, remove weeds and residue before planting and inspect soil around clipped plants.
Protect vulnerable transplants
Use collars or other physical barriers around high-value transplants when cutworm clipping is likely, and use row covers only when they go on before pests are trapped underneath.
Keep moisture decisions separate
Do not dry seedlings to the point of stress just to suppress slugs; use the wet-soil, mulch, and watering checks to balance pest habitat with crop establishment.
